Evidence-Based, Occupational-Therapy-Driven Rehabilitation for Functional Neurological Disorder (FND)
Functional Neurological Disorder (FND) is a complex neurological condition that affects how the brain and body communicate. Symptoms can include weakness, tremor, gait changes, functional seizures, sensory symptoms, speech changes, swallowing difficulties, fatigue, pain, and cognitive complaints. These symptoms are real, involuntary, and often profoundly disruptive to daily life, even when routine investigations such as MRI, EEG, or bloodwork are normal or inconclusive (Espay et al., 2018; Dworetzky et al., 2025).
At Clinique Vivago, our approach to Functional Neurological Disorder treatment is grounded in modern rehabilitation principles and strongly informed by occupational therapy. That means treatment is not limited to discussing symptoms in the abstract. Instead, it focuses on helping people rebuild function in daily life: moving through the world more safely, returning to work or school, re-establishing routines, tolerating meals, participating socially, and reconnecting with meaningful activities and roles (Nicholson et al., 2020).
Treatment may be delivered in regularly occurring sessions, sometimes several times per week, depending on the person’s needs, the severity of their disability, and whether a more intensive rehabilitation format is appropriate. Current reviews emphasize that FND care is often most helpful when it is structured, individualized, multidisciplinary, and focused on functional improvement rather than on symptom description alone (Espay et al., 2018; Dworetzky et al., 2025).

From “Conversion Disorder” to Functional Neurological Disorder
FND was historically called conversion disorder, a term that came from older theories suggesting that psychological conflict was being “converted” into physical symptoms. The field has shifted toward the term Functional Neurological Disorder because it better reflects current understanding: the problem is not that symptoms are fabricated or imaginary, but that there is a disruption in how brain and body systems are functioning together (Espay et al., 2018).
This change in language matters clinically. It reduces stigma, better reflects contemporary neuroscience, and helps patients understand that they are dealing with a real disorder of nervous system functioning. Modern FND literature also emphasizes that symptoms are involuntary. People are not consciously deciding to produce tremor, weakness, speech changes, seizures, or swallowing symptoms (Voon et al., 2010; Espay et al., 2018).
Why Symptoms Are Real Even When Tests Are Normal
One of the most distressing parts of living with FND is being told that tests are “normal” while symptoms continue to feel intense, frightening, and disabling. This can leave people feeling invalidated or as though their symptoms are not being taken seriously. It is important to say clearly: normal tests do not mean symptoms are not real (Espay et al., 2018).
Most common medical tests are designed to identify structural abnormalities such as stroke, tumor, inflammation, nerve damage, degenerative disease, or major electrical abnormalities. FND, however, is primarily a disorder of function rather than visible structural damage. That is why many people with FND have normal imaging or inconclusive tests despite having very real symptoms (Espay et al., 2018; Perez et al., 2021).
A useful analogy is hardware versus software. In structural neurological disease, there is often a hardware problem. In FND, the hardware may be intact, but the software, signaling, or network coordination is not working properly. Functional neuroimaging and neurobiological models increasingly support the idea that disruptions in networks involved in movement, attention, body awareness, emotion regulation, and threat processing play an important role in FND (Perez et al., 2021; Edwards et al., 2012).
This also helps explain why symptoms can feel so physical. Walking, swallowing, speaking, sensing, and moving are normally highly automatic processes. When those automatic systems become dysregulated, people may experience symptoms as effortful, unpredictable, unsafe, or overwhelming. That does not make the symptoms less neurological. It makes them functional and real (Espay et al., 2018; Dworetzky et al., 2025).
Core Principles of Evidence-Based FND Treatment
Current FND treatment models typically combine several elements: education about the diagnosis, rehabilitation through activity, reduction of self-directed attention and hypervigilance, nervous system regulation, self-management strategies, and psychological or behavioral support when indicated (Espay et al., 2018; Nielsen et al., 2015; Nicholson et al., 2020).
A major principle across the physiotherapy, occupational therapy, and speech-language consensus papers is that treatment should not revolve around repeatedly checking symptoms. Instead, it should help people reconnect with more automatic patterns of movement, speech, swallowing, and participation in daily life. The treatment target is not just “feeling less symptomatic,” but becoming more able to function, engage, and live (Nielsen et al., 2015; Nicholson et al., 2020; Baker et al., 2021).
Rebuilding Daily Structure and Schedule
FND often robs people of their schedule. Symptoms may make daily life feel unpredictable, and over time many people stop planning, stop initiating, or stop trusting that they can follow through with basic routines. This can affect waking, hygiene, meals, movement, school attendance, work capacity, social contact, and sleep. Occupational therapy guidance for FND specifically emphasizes rehabilitation within real-life routines and meaningful occupations (Nicholson et al., 2020).
A key part of treatment is often helping the person re-establish a sustainable daily rhythm. This may involve structured morning and evening routines, scheduling meaningful activity into the day, balancing rest with engagement, pacing to reduce boom-and-bust cycles, and gradually restoring predictability. Reconnecting with a schedule is not superficial. It is often central to helping the nervous system feel safer, more regulated, and more able to support everyday function (Nicholson et al., 2020; Dworetzky et al., 2025).
Reducing Hypervigilance and Body Checking
One of the most important and often under-explained parts of FND treatment is reducing hypervigilance, or the constant monitoring of bodily sensations. Many people with FND become understandably preoccupied with checking whether they feel weak, whether a swallow feels safe, whether a tremor is starting, whether speech sounds normal, or whether a seizure might happen. The physiotherapy and speech-language consensus recommendations both identify self-directed attention as a major treatment target (Nielsen et al., 2015; Baker et al., 2021).
This checking makes sense as a survival response. But when attention becomes locked onto bodily sensations, it can interfere with automatic motor and sensory processes and reinforce a cycle of fear, monitoring, and symptom amplification. Treatment therefore often involves helping people gently reduce checking, shift attention toward the outside world or meaningful tasks, tolerate uncertainty more safely, and re-learn how to live in their body with less constant alarm. For many people, this is one of the most transformative aspects of treatment (Nielsen et al., 2015; Nicholson et al., 2020; Baker et al., 2021).
Treating Functional Tremor and Other Functional Movement Symptoms
Overview
Functional tremor and other functional movement symptoms are among the most common and most disabling presentations of FND. People may experience tremor, limb weakness, gait changes, abnormal posturing, jerky movements, loss of coordination, or a sense that a limb is not responding normally. These symptoms may fluctuate from hour to hour or day to day, and they often worsen under stress, fatigue, sensory overload, or heightened self-monitoring (Espay et al., 2018).
These symptoms can look similar to Parkinsonism, essential tremor, multiple sclerosis, stroke, dystonia, or other movement disorders. What distinguishes them is not that they are less real, but that they reflect a functional disruption in motor control rather than structural damage to the nervous system. FND movement symptoms are therefore genuine neurological symptoms, even though the mechanism is different from that seen in degenerative or lesional disease (Edwards & Bhatia, 2012; Espay et al., 2018).
Why Functional Tremor and Movement Symptoms Occur
Movement normally depends on highly coordinated brain systems involving the motor cortex, basal ganglia, cerebellum, prediction systems, body awareness, and attention. In FND, there appears to be altered communication across these systems, especially in the interaction between movement control and self-directed attention. When attention becomes overly fixed on how movement is happening, movements that would ordinarily be automatic can become disrupted, slowed, tremulous, effortful, or inconsistent (Edwards et al., 2012; Perez et al., 2021).
Functional tremor is a particularly important example because it is often worsened by attention and may change with distraction or altered rhythm. Occupational therapy recommendations for FND even include practical examples of intervention strategies for functional tremor, such as superimposing an alternative rhythm and gradually slowing movement toward rest, or using the unaffected limb to influence rhythm and coordination (Nicholson et al., 2020 supplementary material).
How Therapy Helps
Treatment focuses on restoring automaticity, not on endlessly analyzing the symptom. Consensus recommendations for physiotherapy emphasize education, movement retraining, addressing illness beliefs, reducing self-directed attention, and building self-management strategies in a positive, non-judgmental rehabilitation context (Nielsen et al., 2015).
For tremor, weakness, gait changes, or inconsistent movement, therapy often aims to:
-
practice normal movement patterns within meaningful activity
-
redirect attention away from the mechanics of the symptom
-
reduce fear and avoidance around movement
-
rebuild confidence in walking, balance, transfers, reaching, and daily tasks
-
support pacing so that progress remains sustainable
Rather than asking, “Is the tremor still there?” treatment often asks, “How can we help your nervous system move more automatically while you do something meaningful?” That shift is central to rehabilitation in FND (Nielsen et al., 2015; Nicholson et al., 2020).
What Treatment May Look Like
In practice, treatment may involve walking while engaged in an external task, using rhythm or dual-task techniques, practicing reaching or carrying in real contexts, building functional endurance, or using meaningful daily activities to reinforce more efficient movement patterns. Occupational therapy may also address how tremor or weakness affects dressing, showering, meal preparation, school tasks, work demands, driving routines, or community participation (Nicholson et al., 2020).
For some individuals, progress begins when they stop treating the limb as fragile and start re-engaging with it in guided, supported ways. For others, the biggest change comes from decreasing constant internal monitoring. Either way, treatment is usually less about “forcing” movement and more about helping the brain find safer, more automatic ways to move again (Nielsen et al., 2015).
Reducing Functional Seizures
Dissociative Seizures / Psychogenic Non-Epileptic Seizures (PNES)
Overview
Functional seizures are one of the best-known presentations of FND. They may involve shaking, collapse, changes in responsiveness, staring, altered awareness, or episodes that resemble epilepsy but occur without epileptic electrical activity on EEG. These episodes can be extremely frightening and can lead to major disruption in daily life, including loss of independence, avoidance of leaving the house, fear of being alone, difficulty working, and withdrawal from school or social life (Goldstein et al., 2020; Dworetzky et al., 2025).
Functional seizures are real and involuntary. They are not faked, staged, or consciously produced. That point is essential, because people with dissociative seizures are often misunderstood, including by people around them. Modern FND literature is very clear that this symptom cluster deserves serious, evidence-informed care (Goldstein et al., 2020; Dworetzky et al., 2025).
Why Functional Seizures Occur
The exact mechanism is still being studied, but functional seizures are thought to involve disruptions in emotional regulation, threat processing, bodily awareness, dissociation, and stress response systems. Episodes may be triggered or worsened by emotional overwhelm, fatigue, sensory overload, conflict, internal arousal, or the anticipatory fear of another episode (Goldstein et al., 2020).
Over time, many people become highly vigilant for warning signs. They may scan their body constantly, avoid situations associated with prior episodes, or live with ongoing fear of collapse. This anticipation can become part of the maintaining cycle. Treatment therefore often addresses not just the seizure event itself, but the broader nervous-system context around it, including fear, avoidance, dysregulation, and disrupted daily routines (Goldstein et al., 2020; Nicholson et al., 2020).
How Therapy Helps
The CODES trial showed that CBT-informed treatment, when added to standardized medical care, improved several important outcomes for adults with dissociative seizures, and secondary analysis suggested lower monthly seizure frequency at 6 months in the CBT plus standardized care group (Goldstein et al., 2020; Goldstein et al., 2022).
In practice, therapy may help the person:
-
identify triggers and prodromal signs
-
understand the seizure cycle
-
reduce fear and catastrophic anticipation
-
use grounding and regulation tools earlier
-
reintroduce activities that have been avoided
-
rebuild a predictable schedule that stabilizes the day
Occupational therapy may also help restore life around the seizures: routines, self-care, education, work planning, pacing, and community participation. This matters because sometimes the disorder expands not only through episodes themselves, but through the shrinking of life around them (Nicholson et al., 2020).
What Treatment May Look Like
Treatment may involve mapping triggers, identifying what happens before, during, and after episodes, developing an early-response plan, using grounding strategies, reducing “checking” for bodily warning signs, and gradually resuming meaningful activities. Therapy may also address the emotional aftermath of episodes, shame, loss of confidence, and fear of being witnessed in public (Goldstein et al., 2020).
A major goal is not only reducing seizure burden, but helping the person feel safer, less trapped, and more able to live. This includes building routines, confidence, social re-entry, and functional independence alongside seizure-specific treatment (Nicholson et al., 2020; Dworetzky et al., 2025).
Addressing Swallowing Difficulties
Functional Dysphagia and Swallowing Symptoms in FND
Overview
Some individuals with FND experience swallowing difficulties, sometimes referred to as functional dysphagia. Symptoms may include difficulty initiating swallowing, throat tightness, the sensation that food is getting stuck, fear of choking, repeated checking of swallows, or avoidance of certain textures, meals, or eating in public. Speech, language, and swallowing symptoms are recognized in FND, although this remains a relatively under-researched area compared with movement symptoms and dissociative seizures (Barnett et al., 2019; Baker et al., 2021).
This is an area that must be approached carefully. New or persistent swallowing symptoms should always be medically assessed first to rule out structural, neurological, ENT, or gastrointestinal causes. Functional swallowing difficulties are considered in the context of appropriate medical work-up and a broader FND formulation (Baker et al., 2021; NHS inform FND resource).
Why Swallowing Becomes Difficult
Swallowing is usually a highly automatic process. In FND, however, the person may become intensely aware of every swallow. Fear of choking, hyper-awareness of throat sensations, and repeated checking can interfere with the fluid coordination of swallowing. This mirrors a broader principle seen across FND: when automatic functions become over-monitored, they may become harder to perform smoothly (Baker et al., 2021; Nielsen et al., 2015).
Some people also begin to avoid eating situations, rush or restrict meals, or lose confidence in social eating. Over time, the symptom is no longer only about swallowing mechanics; it becomes connected to fear, vigilance, isolation, and disruption of routines. That is one reason treatment often needs to address both symptom experience and participation in daily life (Barnett et al., 2019; Nicholson et al., 2020).
How Therapy Helps
The speech and language therapy consensus recommendations for FND emphasize education, symptomatic treatment, addressing self-directed attention, and integrating cognitive-behavioral principles within a supportive environment (Baker et al., 2021).
For functional swallowing symptoms, treatment may involve:
-
reducing excessive monitoring of swallowing sensations
-
lowering throat-related threat and fear
-
using calming or grounding strategies around meals
-
gradually reintroducing avoided foods or contexts when clinically appropriate
-
restoring confidence in the body’s automatic swallowing process
Occupational therapy may complement this by helping rebuild structured mealtimes, meal preparation routines, social participation around eating, and day structure, especially when eating has become associated with anxiety or withdrawal (Nicholson et al., 2020).
What Treatment May Look Like
In practice, treatment may include slowing the pace around meals, shifting attention outward, reducing repeated “test swallows,” building a more predictable eating routine, and working toward eating in settings that have become difficult. For some people, the central task is not merely swallowing better, but feeling safer in their body while eating. That distinction is often crucial in FND rehabilitation (Baker et al., 2021; Barnett et al., 2019).
Treating Functional Speech and Voice Symptoms
Overview
FND can affect communication in multiple ways. People may experience slurred speech, difficulty initiating speech, variable voice loss, stuttering-like disruptions, inconsistent speech patterns, whispering, mutism, or speech that worsens in particular emotional or social contexts. Speech, language, and swallowing symptoms are increasingly recognized as important parts of the FND spectrum, though they remain under-researched and are still sometimes missed in practice (Barnett et al., 2019; Baker et al., 2021).
These symptoms can be socially devastating. Communication difficulties can affect work, teaching, relationships, phone calls, self-advocacy, and everyday confidence. People may begin avoiding meetings, social events, or conversations because speaking feels effortful, embarrassing, or unreliable. As with other FND symptoms, the impact extends far beyond the symptom itself (Baker et al., 2021).
Why Speech Symptoms Occur
Speech depends on coordinated motor planning, breathing, voicing, articulation, and timing, all of which are influenced by automaticity and attention. In functional speech disorders, self-monitoring, threat processing, and abnormal movement patterns may interfere with normal speech production. Positive diagnosis can sometimes be supported by how rapidly symptoms respond to symptomatic therapy, which is a feature noted in the speech literature (Duffy, 2016; Baker et al., 2021).
In plain language, speech may become harder when the person becomes overly focused on how they are sounding, whether their voice will come out, whether they will get stuck, or whether others will notice. As with swallowing and movement, over-control can interfere with automatic function (Baker et al., 2021).
How Therapy Helps
The 2021 consensus recommendations for speech and language therapy in FND explicitly state that treatment should address illness beliefs, self-directed attention, and abnormal movement patterns through education, symptomatic treatment, and cognitive-behavioral principles in a supportive therapeutic context (Baker et al., 2021).
Treatment may therefore focus on:
-
reducing internal monitoring of speech
-
restoring more automatic communication patterns
-
using breathing, voicing, or pacing strategies where appropriate
-
practicing speech in functional contexts rather than only drills
-
decreasing avoidance of speaking situations
-
rebuilding communication confidence
Occupational therapy may also support the functional side of recovery by helping the person return to speaking demands in daily life: work conversations, customer interactions, classroom participation, social calls, family routines, and self-advocacy tasks (Nicholson et al., 2020).
What Treatment May Look Like
In practice, therapy may involve guided conversation, speaking while engaged in an external task, graded exposure to feared speaking situations, or using voice and breathing strategies in real-life settings. The goal is not simply “better speech in the therapy room,” but more reliable, less effortful communication in the person’s actual life. That functional transfer is especially important in FND rehabilitation (Baker et al., 2021; Duffy, 2016).
Treating Sensory Symptoms in FND
Overview
Sensory symptoms are common in FND and can include numbness, tingling, altered touch perception, sensory loss, painful sensations, unusual heaviness, or hypersensitivity to noise, light, movement, or other stimuli. Sensory symptoms are often discussed less than movement symptoms, but emerging literature suggests they are both prevalent and disabling (Bennett et al., 2021; Ranford et al., 2020).
Some individuals also report that sensory experiences trigger or worsen other FND symptoms. For example, noise or visual overload may worsen tremor, fatigue, dissociation, or seizures. A biopsychosocial understanding of sensory processing is therefore often clinically useful in FND (Ranford et al., 2020; McCombs et al., 2024).
Why Sensory Symptoms Occur
Sensory experience is not a simple “input-output” phenomenon. It is shaped by the nervous system’s interpretation of signals, as well as by attention, arousal, prediction, and threat processing. In FND, altered network functioning may change how sensations are amplified, filtered, interpreted, or linked to other symptoms (Perez et al., 2021; Bennett et al., 2021).
When a person becomes highly vigilant to bodily sensations, the nervous system may become even more reactive. This can create a feedback loop in which sensory symptoms feel more intense, more alarming, and more disabling, especially in stressful or overstimulating environments (Ranford et al., 2020).
How Therapy Helps
Treatment may focus on:
-
reducing sensory hypervigilance
-
understanding triggers and overload patterns
-
rebuilding tolerance to sensation or stimulation
-
using grounding and sensory regulation tools
-
reducing avoidance of environments that have become associated with symptoms
A 2024 OT cohort study reported sensory sensitivity and sensation-avoidance patterns in FND and highlighted the relevance of sensory-informed treatment approaches for some patients (McCombs et al., 2024).
Occupational therapy is especially relevant here because it can help translate sensory understanding into day-to-day modifications and participation strategies: how to manage a grocery store, a commute, a classroom, a workday, a meal, or a social event without tipping the nervous system into overload (Nicholson et al., 2020).
What Treatment May Look Like
In practice, this may include identifying sensory triggers, using structured recovery strategies, gradually reintroducing avoided environments, and experimenting with attention-redirection and sensory regulation tools. The aim is not to remove all discomfort from life, but to help the person feel less at the mercy of sensation and more able to function meaningfully despite it (Ranford et al., 2020; Nicholson et al., 2020).
Treating Fatigue and Brain Fog
Overview
Fatigue is one of the most common and frustrating symptoms in FND. Many people describe persistent exhaustion, reduced endurance, brain fog, slowed thinking, poor concentration, cognitive overload, or the sense that ordinary tasks now require far more effort than before. Recent practical reviews explicitly note fatigue and cognitive complaints as common features that often need direct attention in treatment (Dworetzky et al., 2025; Lehn et al., 2025).
This fatigue is often misunderstood. It is not simply laziness or a lack of motivation. For many people with FND, basic motor and cognitive processes that used to happen automatically now require much more conscious effort. Constant monitoring, nervous-system arousal, poor sleep, symptom management, and repeated internal checking can all contribute to deep fatigue (Dworetzky et al., 2025).
Why Fatigue and Brain Fog Occur
When the nervous system is operating in a state of persistent vigilance, or when ordinary functioning requires extra cognitive control, the result can be mental and physical depletion. Fatigue may also be worsened by disrupted routines, irregular meals, poor pacing, pain, sensory overload, dissociation, or fear-based avoidance patterns (Dworetzky et al., 2025; Nicholson et al., 2020).
In some individuals, fatigue becomes part of a boom-and-bust cycle: on a “better” day they overdo it, then crash afterward, which further destabilizes routines and reinforces uncertainty. That is why fatigue work in FND often overlaps closely with schedule reconstruction, pacing, and functional planning (Nicholson et al., 2020).
How Therapy Helps
Treatment may focus on:
-
pacing and energy management
-
reducing cognitive overload
-
restoring more predictable daily rhythms
-
building sustainable work-rest cycles
-
gradually increasing participation without repeated crashes
-
addressing symptom-monitoring habits that consume mental energy
Occupational therapy is especially useful here because fatigue is rarely solved by rest alone. It often requires a detailed look at how the person is living, where energy is being lost, what tasks are costing too much, how the day is structured, and how meaningful activity can be reintroduced without overwhelming the system (Nicholson et al., 2020; Dworetzky et al., 2025).
What Treatment May Look Like
In practice, treatment may include mapping the person’s fatigue patterns, developing more stable routines, scheduling activity more strategically, alternating cognitive and physical demands, protecting recovery time without collapsing into inactivity, and gradually increasing tolerance for meaningful roles. The goal is not perfection. It is helping the person live with more steadiness, less overwhelm, and greater access to work, study, self-care, and relationships (Nicholson et al., 2020; Dworetzky et al., 2025).
Treating Pain in Functional Neurological Disorder
Overview
Pain is common in FND and is increasingly recognized as a major clinical issue rather than a side note. A 2024 systematic review and meta-analysis found that chronic pain symptoms and pain-related diagnoses are common in FND and deserve more attention in both research and practice (Steinruecke et al., 2024).
People may experience headaches, widespread pain, muscle pain, joint pain, body tension, or pain that fluctuates along with other FND symptoms. Pain can interact with fatigue, sensory sensitivity, poor sleep, reduced movement, and fear of activity. Over time, it may narrow the person’s world just as much as seizures or gait symptoms do (Steinruecke et al., 2024; Dworetzky et al., 2025).
Why Pain Occurs
Pain is shaped by more than tissue injury alone. It reflects complex interactions between sensory processing, nervous-system arousal, prediction, attention, emotion, and context. In FND, altered nervous-system functioning may contribute to pain amplification or greater sensitivity to bodily sensations, especially when the person is already living in a state of vigilance or overload (Steinruecke et al., 2024; Bennett et al., 2021).
Pain may also become linked to protective avoidance: the person moves less, fears provoking symptoms, loses conditioning, and becomes even more sensitive or disabled. That does not mean the pain is “just stress.” It means the nervous system has become part of the pain picture and must be addressed as such (Steinruecke et al., 2024).
How Therapy Helps
Treatment may focus on:
-
reducing pain-related fear and avoidance
-
pacing activity more effectively
-
lowering nervous-system arousal
-
gradually rebuilding tolerance for movement and participation
-
addressing catastrophic interpretation of symptoms
-
restoring meaningful daily function despite pain
Occupational therapy can be especially helpful in translating pain management into real life: how to shower, cook, work, sit through meetings, socialize, commute, or rest in ways that are restorative rather than deconditioning (Nicholson et al., 2020).
What Treatment May Look Like
In practice, this may include graded re-engagement in activity, schedule rebuilding, movement confidence work, sensory and regulation strategies, and reducing the cycle of checking, fearing, and avoiding painful sensations. The goal is not always immediate pain elimination. Often the first major win is helping the person reclaim function, autonomy, and confidence even while symptoms fluctuate (Steinruecke et al., 2024; Dworetzky et al., 2025).
Intensive Rehabilitation for Functional Neurological Disorder
Some individuals benefit from a more structured and intensive format of care, particularly when symptoms are severe, longstanding, interacting across several domains, or significantly reducing independence. Multidisciplinary treatment studies and modern reviews support intensive, coordinated approaches for selected patients, while also emphasizing that outcomes vary and treatment should be individualized (Demartini et al., 2014; Espay et al., 2018; Dworetzky et al., 2025).
An intensive program may include regularly occurring sessions several times per week, coordinated goal-setting, occupational therapy, movement retraining, nervous-system regulation, schedule reconstruction, fatigue management, and psychological support when indicated. This kind of structure can be especially useful when a person’s life has narrowed substantially around symptoms and they need repeated, consistent support to begin expanding it again (Nicholson et al., 2020; Nielsen et al., 2015).
Recovery Expectations
It is important to be hopeful and honest at the same time. FND is a real and potentially reversible source of disability, but there is still much to learn about which treatments work best for which patients, at what intensity, and under what conditions. Current reviews emphasize both the progress in the field and the continuing need for individualized, multidisciplinary care (Espay et al., 2018; Dworetzky et al., 2025; Thomas et al., 2025).
Results vary. Some people improve quickly. Others improve gradually. Some continue to have flare-ups even as their functioning becomes better. The right message is not false certainty. It is that meaningful improvement is possible, and many people do get better support, better function, and better quality of life with appropriate treatment (Espay et al., 2018; Thomas et al., 2025).
FAQ — Functional Neurological Disorder Treatment
What is the best treatment for Functional Neurological Disorder (FND)?
The best treatment for Functional Neurological Disorder usually involves a multidisciplinary rehabilitation approach. Depending on the person’s symptoms, treatment may include occupational therapy, physiotherapy, psychotherapy, nervous system regulation strategies, education about the diagnosis, and structured support to return to meaningful daily activities. FND treatment is most effective when it focuses on restoring function, reducing symptom-related fear, and rebuilding confidence in the body.
Can Functional Neurological Disorder be treated?
Yes. Functional Neurological Disorder can be treated, and many people experience meaningful improvement in their symptoms, daily functioning, and quality of life with appropriate care. Recovery varies from person to person, but structured rehabilitation can help reduce disability and support long-term progress.
Is Functional Neurological Disorder curable?
Some people experience major improvement or near-resolution of symptoms, while others have a more gradual or fluctuating recovery. Because FND is a complex and still-evolving area of neurology, it is more accurate to say that meaningful recovery is possible rather than promising a cure. Treatment often focuses on helping people function better, feel safer in their body, and return to daily life.
Why are FND symptoms real even when tests are normal?
FND symptoms are real because they reflect a problem with how the nervous system is functioning, not necessarily a visible structural problem on MRI, EEG, or other routine medical tests. Many standard tests are designed to detect damage or disease in the structure of the brain or nervous system. In FND, the difficulty is often in the brain’s signaling, control, and regulation systems.
What does occupational therapy do for Functional Neurological Disorder?
Occupational therapy helps people with Functional Neurological Disorder rebuild their daily functioning. This may include support with routines, self-care, work, school, energy management, sensory regulation, cognitive fatigue, community participation, and confidence in movement. Occupational therapy is especially relevant in FND because it focuses on helping people return to meaningful life activities.
Can occupational therapy help with functional tremor or weakness?
Yes. Occupational therapy can help with functional tremor, weakness, and other movement symptoms by focusing on functional movement retraining in real-life activities. Treatment may involve reducing body checking, restoring more automatic movement patterns, rebuilding confidence in mobility, and gradually returning to daily tasks.
Can therapy help reduce functional seizures or PNES?
Yes. Therapy can help reduce the frequency, severity, or impact of functional seizures, also called PNES or dissociative seizures. Treatment often includes education, identifying triggers and warning signs, nervous system regulation, reducing fear of episodes, and gradually rebuilding routines and daily participation.
What are functional seizures?
Functional seizures are real and involuntary episodes that resemble epileptic seizures but occur without epileptic electrical activity in the brain. They are a recognized presentation of Functional Neurological Disorder and can be treated through specialized rehabilitation and psychological approaches.
Can Functional Neurological Disorder affect swallowing?
Yes. Some people with Functional Neurological Disorder experience swallowing difficulties, sometimes referred to as functional dysphagia. Symptoms may include throat tightness, fear of choking, difficulty initiating swallowing, or the feeling that food is stuck. Swallowing difficulties should always be medically assessed first to rule out structural causes.
Can Functional Neurological Disorder affect speech?
Yes. FND can affect speech and voice. Some people experience slurred speech, difficulty initiating speech, changes in voice, stuttering-like symptoms, or speech that worsens under stress. Treatment may include speech-language therapy, attention redirection, breathing regulation, and functional communication practice.
Can Functional Neurological Disorder cause numbness, tingling, or sensory symptoms?
Yes. Functional Neurological Disorder can cause sensory symptoms such as numbness, tingling, altered sensation, burning, heaviness, or sensory hypersensitivity. These symptoms are real and may improve with treatment focused on sensory regulation, reducing hypervigilance, and gradually rebuilding tolerance to daily environments and sensations.
Can Functional Neurological Disorder cause fatigue and brain fog?
Yes. Fatigue and brain fog are very common in Functional Neurological Disorder. Many people experience mental fatigue, slowed thinking, poor concentration, and cognitive overload. Treatment may include pacing, energy management, routine building, cognitive strategies, and nervous system regulation.
Can Functional Neurological Disorder cause chronic pain?
Yes. Chronic pain is common in people living with Functional Neurological Disorder. Pain may include headaches, muscle tension, body pain, or widespread discomfort. Treatment often focuses on reducing nervous system sensitization, improving pacing, gradually rebuilding activity, and supporting better daily function despite pain.
Why does reducing body checking matter in FND treatment?
Reducing body checking is an important part of FND treatment because constant monitoring of movement, swallowing, speech, or other bodily sensations can reinforce symptom cycles. Many people with FND become hypervigilant to their body after frightening or unpredictable symptoms. Therapy helps shift attention away from constant checking and toward safer, more automatic functioning.
Why is rebuilding a daily routine important in FND treatment?
Rebuilding a daily routine is important because Functional Neurological Disorder often disrupts schedules, predictability, and confidence in everyday life. Structured routines can help reduce avoidance, stabilize the nervous system, improve energy management, and support return to work, school, meals, movement, and social participation.
Do people recover from Functional Neurological Disorder?
Many people do improve with the right treatment, although recovery looks different for everyone. Some people improve significantly, some recover gradually, and others continue to have flare-ups while still gaining better function and quality of life. Hope is realistic, but treatment should be individualized and grounded in realistic expectations.
When should I seek treatment for Functional Neurological Disorder?
You should seek treatment if FND symptoms are interfering with daily life, mobility, work, school, swallowing, speech, emotional well-being, or independence. Early treatment can help reduce disability, improve coping, and support a more effective rehabilitation process.
