What is Functional Neurological Disorder
Functional Neurological Disorder (FND) is a condition that affects how the brain and nervous system send and receive signals, even though there is no structural damage to the nervous system. While the brain’s anatomy remains intact, its functioning becomes disrupted. This can lead to symptoms that feel neurologically familiar like tremors, seizures, or limb weakness, but arise from a functional disconnect rather than a clear-cut injury or disease.
A Modern Understanding of FND
Historically known as conversion disorder, FND is now recognized in both the DSM-5 and ICD-11 as a legitimate neuropsychiatric condition. The term “functional” reflects the nature of the disruption: it is not about damage to the nervous system, but about how it functions. Importantly, symptoms are not imagined or fabricated. They are the result of real neurological changes in the way the brain processes information, often influenced by stress, trauma, or emotional regulation patterns.
How Common is Functional Neurological Disorder?
FND is more prevalent than many people realize. According to a 2023 review published in the journal Medicine, incidence rates of Functional Neurological Disorder are estimated at 4 to 12 cases per 100,000 people annually, with population studies suggesting a broader prevalence of 50 to 100 cases per 100,000. These figures place FND among the more commonly encountered conditions in neurology outpatient settings.
The Patient Experience
Because FND often presents with symptoms similar to conditions like epilepsy, stroke, or multiple sclerosis, it can be difficult to diagnose and sometimes misunderstood. Individuals with FND may feel frustrated or dismissed, particularly if medical testing does not show a definitive cause. Yet their symptoms are real, often disruptive, and deserving of treatment that bridges both physical and emotional care needs.
Who is Most Likely to Develop FND?
Functional Neurological Disorder can affect anyone, including children and adults. However, it is more commonly diagnosed in women, and symptoms often begin in a person’s late 20s to late 30s, depending on the type. For example, functional seizures often start in the late 20s, while functional movement symptoms tend to emerge in the late 30s.
Common Symptoms of Functional Neurological Disorder
The symptoms of Functional Neurological Disorder are diverse and often resemble those seen in other neurological conditions. What distinguishes FND is that these symptoms result from changes in how the brain functions rather than from structural damage. Routine scans or tests may appear normal, even when symptoms are clearly present and disruptive.
Because of this, individuals with FND frequently feel misunderstood or dismissed. Recognizing these patterns is critical for accurate diagnosis and compassionate care.
Neurological and Cognitive Symptoms
Functional Seizures (Dissociative Seizures)
Episodes that resemble epileptic seizures without abnormal brain activity, often including confusion, memory lapses, or emotional dissociation.
Limb Weakness or Paralysis
Sudden or fluctuating weakness, typically in one limb or one side of the body
Tremors and Involuntary Movements
Shaking, twitching (myoclonus), or repetitive postures (dystonia); symptoms may shift or improve with distraction.
Dissociation
Feeling detached from one’s thoughts, emotions, or physical body
Gait and Balance Disturbances
Difficulty walking, loss of coordination, or sudden collapses without a neurological explanation
Cognitive Fog and Concentration Problems
Difficulty with memory, attention, and mental clarity (“brain fog”)
Fatigue
Persistent exhaustion, slowed movement, or reduced physical stamina
Sensory, Communication and Internal Symptoms
Visual Disturbances
Blurred or double vision, or episodes of temporary vision loss
Sensory Changes
Numbness, tingling, or sensory loss not following typical nerve patterns
Autonomic Dysfunction
Episodes of dizziness, heart palpitations, temperature dysregulation, or digestive issues due to disruptions in the autonomic nervous system
Speech Difficulties
Slurred speech, inability to speak, or sudden onset of stuttering
Hearing Problems
Numbness, tingling, or sensory loss not following typical nerve patterns
Swallowing or Throat Sensations
Feeling of a lump in the throat, difficulty swallowing, or unexplained vocal tightness
Pain and Chronic Migraines
Unexplained physical pain, including recurring migraines or body aches
The presentation and severity of symptoms can vary widely from person to person. According to both the NIH and the Mayo Clinic, symptoms may appear suddenly, may worsen under stress, and can lessen with distraction. They are not intentionally produced and may affect any part of the body.
FND is a genuine disorder of brain functioning, not a psychological fabrication. Recognizing the symptom profile is a key part of diagnosis and of validating the lived experience of those affected.
Subtypes of Funtional Neurological Disorder
The wide range of symptoms involved in Functional Neurological Disorder (FND) fall into different clinical subtypes. These are not separate diagnoses, but rather different ways that the brain’s functioning may become disrupted. Understanding the presentation can help guide effective treatment.
Common subtypes include:
Functional Motor Disorder
This subtype involves problems with movement, such as tremors, limb weakness, muscle stiffness, or difficulties with walking and coordination. These symptoms often fluctuate and may worsen under stress. Although they may look like neurological conditions such as Parkinson’s disease or stroke, imaging and other tests do not show damage to the nervous system. FMD is one of the most commonly diagnosed forms of FND.
Functional Seizures
Also called dissociative or non-epileptic seizures, these episodes resemble epileptic seizures but occur without abnormal electrical activity in the brain. Symptoms may include convulsing, unresponsiveness, or sudden collapses. Functional seizures can be confusing and frightening, and people with this presentation are often referred for behavioral treatment after ruling out epilepsy through EEG and neurological evaluation.
Functional Sensory Symptoms
This subtype includes changes in sensation, such as numbness, tingling, vision or hearing changes, or sensitivity to light and touch. These symptoms can affect one or multiple areas of the body and may vary from day to day. They are often misunderstood or minimized, but they reflect real changes in how the brain processes sensory input.
Functional Cognitive Symptoms
People with FCD experience memory problems, mental “fogginess,” trouble concentrating, or slowed thinking that can interfere with daily functioning. Unlike neurodegenerative conditions, FCD does not involve structural brain changes. Instead, symptoms reflect a disruption in attention, self-monitoring, and cognitive processing. FCD is often under-recognized and can be especially distressing when individuals feel dismissed or misunderstood.
We Treat All Symptoms
Many individuals experience a combination of these symptom types. At Rowan Center, we recognize and treat the full spectrum of FND presentations using a compassionate and evidence-based approach tailored to each person’s experience.
For referring providers: If you’re supporting a patient with motor symptoms, cognitive concerns, or functional seizures, we welcome collaboration. Refer a patient or learn more about our multidisciplinary care.
Understanding the Causes of Functional Neurological Disorder
No Single, Simple Cause
Functional Neurological Disorder (FND) doesn’t have a single, simple cause. Instead, it results from a combination of biological, psychological, and social factors. These may include changes in brain connectivity, difficulty processing emotions, learned symptom patterns, or unresolved stress.
Disrupted Brain Connectivity Plays a Key Role
Brain imaging has shown that people with FND often have altered communication between areas involved in movement, emotion, and attention. In some cases, the limbic system, which helps manage emotional response, becomes overactive, increasing the brain’s sensitivity to stress and body signals.
It’s About Function, Not Structure
FND is not caused by damage to the brain. Instead, it is a problem with how the brain interprets and responds to information, such as a misfire between intention and action, or sensation and understanding.
Risk Factors
While FND is not caused by damage to the brain, psychological and environmental factors may influence its development in some individuals. These can include prior trauma, chronic stress, or co-occurring conditions such as anxiety, depression, or PTSD. For children and adolescents, contributing influences might include bullying, family conflict, or peer pressure.
However, these factors are not present in every case. FND can occur without any clear emotional or psychological trigger, which is why it is considered a complex, multifactorial condition. Understanding this helps reduce stigma and supports a more compassionate, individualized treatment approach.
How Functional Neurological Disorder is Diagnosed
Functional Neurological Disorder (FND) is diagnosed based on what is present during a clinical exam, not just on what is missing from test results. That means your doctor will look for positive clinical signs that point to FND, rather than simply ruling out other conditions.
There is no single blood test or brain scan that confirms FND. However, neurologists and neuropsychiatrists are trained to identify specific physical signs such as Hoover’s sign, which helps distinguish functional weakness in the legs, or entrainment, which is used to evaluate functional tremors.
In the case of functional seizures, diagnosis often involves reviewing video footage of an episode, or monitoring brain activity using tools like EEG to differentiate functional from epileptic seizures.
Testing may also include MRI, EMG, or other imaging to rule out other neurological conditions. Importantly, the presence of depression, anxiety, or trauma is not what determines an FND diagnosis. These may be part of a person’s history, but they are not required for diagnosis.
FND is also recognized in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). According to the DSM-5, diagnosis requires one or more symptoms affecting voluntary motor or sensory function, evidence of incompatibility between the symptom and recognized medical conditions, and that the symptoms cause significant distress or impairment.
FND is diagnosed through observable signs in a neurological exam, not just by ruling out other conditions. The symptoms are real, and help is available.
How Rowan Center Approaches Treatment
Our treatment approach to Functional Neurological Disorder is rooted in compassion, collaboration, and evidence-based care. While each person’s experience is unique, we work as part of a broader interdisciplinary team to support your recovery and long-term well-being. Effective care often involves multiple specialties working together, which may include:
Cognitive Behavioral Therapy
Cognitive Behavioral Therapy (CBT) helps individuals with FND identify patterns of thinking, behavior, or emotion that may reinforce symptoms. It offers tools to better manage stress, reframe internal responses, and support improved daily functioning over time.
Dialectical Behavior Therapy
Dialectical Behavior Therapy (DBT) offers skills-based training in areas like mindfulness, emotion regulation, and distress tolerance. These approaches help individuals better manage arousal, stress responses, and emotional reactivity, which are often heightened in FND.
Psychodynamic Therapy
This insight-oriented therapy explores how past experiences and emotional processing patterns may shape current symptoms. It is especially helpful for individuals whose symptoms may reflect suppressed or unresolved emotions.
Mind-Body Strategies
We use techniques like paced breathing, grounding, and behavioral pacing to help regulate the nervous system. Mindfulness-Based Cognitive Therapy (MBCT) also helps patients observe thoughts and emotions with less reactivity.
Psychoeducation
Understanding FND is an essential part of treatment. Psychoeducation provides individuals and families with clear explanations of how and why symptoms occur, helping reduce fear, improve trust, and build empowerment through knowledge.
Symptom and Pain Management
For individuals experiencing co-occurring symptoms like chronic pain, insomnia, anxiety, or depression, integrated treatment may include non-addictive medications or behavioral strategies. The focus is always on improving function and quality of life.
Collaborative Care
Functional Neurological Disorder often requires support from more than one provider. At Rowan Center, we understand that recovery is strongest when care is multidisciplinary. While our team focuses on the emotional, cognitive, and behavioral aspects of FND, we recognize the importance of partnering with neurologists, physical therapists, occupational therapists, and speech-language pathologists when needed.
Our role is to help ensure mental health care aligns with the broader medical picture. We communicate with referring providers, support patients in building care teams, and stay engaged throughout the recovery process. Whether you’re already working with other specialists or need help finding the right referrals, we can assist in creating a cohesive, coordinated plan.
FND can affect multiple systems: physical, emotional, and neurological. A collaborative care model improves continuity, reduces stress, and ensures that all aspects of your experience are addressed with care and clarity.
