Conversion Disorder Treatment (Functional Neurological Disorder)
What you have is not imaginary. It is not faked. It is not “all in your head” in the dismissive sense that phrase is often meant. It is a condition in which the brain’s ability to send and receive neurological signals has been disrupted — producing genuine neurological symptoms through a mechanism that is functional rather than structural, psychological rather than anatomical.
The symptoms are real. The weakness in your limbs is real. The tremors, the vision changes, the episodes that look like seizures — all of it is real. And the years you may have spent in neurologist offices, having test after test come back normal, being told there is nothing structurally wrong — that experience is real too.
That distinction matters enormously. Because it means the path to recovery runs through the brain — through the psychological and functional mechanisms that produced the disruption — rather than through the neurological hardware that medicine has already examined and found intact.
At Friendly Recovery Center, we provide compassionate, trauma-informed treatment for conversion disorder — also called Functional Neurological Disorder (FND) — across Southern California. As part of our broader somatic symptom and related disorder treatment programs, we offer clinical care that takes your symptoms seriously while addressing what is actually driving them.
What Is Conversion Disorder?
Conversion disorder — formally known in the DSM-5 as Functional Neurological Symptom Disorder (FNSD), and increasingly referred to as Functional Neurological Disorder (FND) — is a condition characterized by neurological symptoms that cannot be explained by a structural neurological disease. These symptoms are real and involuntary — they are not consciously produced or feigned — but they arise from disrupted functional processing in the brain rather than from damage, lesions, or structural abnormalities.
The term “conversion” reflects an older psychoanalytic theory that psychological distress is “converted” into physical symptoms. While this framing has been largely superseded by more contemporary neurobiological models, the name persists in common clinical use alongside the newer FND terminology. For people searching for information about their diagnosis, both terms are important to recognize.
According to the FND Society, functional neurological disorder is estimated to affect between 4 and 12 people per 100,000 — making it the second most common reason for neurological outpatient appointments after headache. Despite this prevalence, it remains one of the most misunderstood and undertreated neurological-psychiatric conditions in clinical practice.
Conversion Disorder vs. Somatic Symptom Disorder — Understanding the Difference
Because conversion disorder and somatic symptom disorder both involve physical symptoms with a significant psychological dimension, they are frequently confused. The distinction is clinically important.
Somatic Symptom Disorder (SSD) involves one or more physical symptoms accompanied by excessive preoccupation, anxiety, and behavioral responses to those symptoms. The defining feature of SSD is the psychological response to physical experience — the catastrophizing, health anxiety, and functional disruption driven by how the person thinks and feels about their symptoms.
Conversion disorder / FND involves specific neurological symptoms — weakness, paralysis, tremor, gait disturbance, sensory loss, vision changes, non-epileptic seizures, speech difficulties — that are produced by functional disruption in the brain’s neurological processing. The defining feature of FND is the neurological presentation itself, not primarily the psychological response to it.
In simpler terms: SSD is primarily about the anxiety around physical symptoms. FND is primarily about the neurological symptoms themselves and the functional brain disruption producing them. Both conditions have significant psychological dimensions, and both respond to psychological treatment — but the specific symptoms, the mechanisms, and the treatment emphases differ.
Signs and Symptoms of Conversion Disorder
Conversion disorder presents with a wide range of neurological symptoms that vary significantly between individuals. The common thread is that the symptoms are genuine, involuntary, and inconsistent with known structural neurological disease.
Motor Symptoms
- Weakness or paralysis — of a limb or one side of the body, without the neurological signs that would be expected from a structural lesion
- Tremor — involuntary shaking that may be present at rest or with movement, differing in character from neurologically-explained tremors
- Gait disturbance — difficulty walking, unusual gait patterns, or collapse without clear structural cause
- Dystonia — sustained muscle contractions producing abnormal postures
- Myoclonus — brief, involuntary muscle jerks
Seizure-Like Episodes
Non-epileptic seizures — also called psychogenic non-epileptic seizures (PNES) — are seizure-like episodes that are not associated with the electrical brain activity patterns of epilepsy. They are among the most common and most clinically challenging presentations of conversion disorder, frequently resulting in misdiagnosis and inappropriate epilepsy treatment before the functional nature of the episodes is identified.
Sensory Symptoms
- Numbness or tingling — in areas inconsistent with the distribution of known nerve pathways
- Visual changes — including blurred or double vision, tunnel vision, or functional vision loss
- Hearing changes — including functional hearing loss
Speech and Swallowing Symptoms
- Dysphonia — changes in voice quality, including whispering or voice loss without structural cause
- Dysarthria — difficulty with speech production
- Globus — the sensation of something stuck in the throat
Non-Epileptic Episodes and Dissociative Symptoms
Many people with conversion disorder also experience dissociative symptoms — episodes of feeling detached from the body, loss of memory, or altered consciousness — that are related to the functional brain disruption and to the trauma histories that frequently underlie the condition.
What Causes Conversion Disorder?
The neurobiological understanding of conversion disorder has evolved significantly in recent decades — from the psychoanalytic “conversion” model toward a contemporary framework that recognizes FND as a disorder of functional brain networks.
The Neurobiological Model
Contemporary research using neuroimaging has identified specific patterns of altered brain network activity in people with FND — particularly involving the connection between the motor and sensory cortex and the limbic system, which processes emotion and threat. The functional disruption is not in the neurological “hardware” but in how the brain’s networks communicate and regulate motor and sensory function under conditions of psychological stress, trauma, or arousal.
A useful analogy is the difference between a hardware failure and a software glitch in a computer system. The brain’s hardware — its structures and anatomy — is intact. The software — how the brain’s networks process and transmit signals — is disrupted in ways that produce genuine neurological symptoms.
Trauma and Psychological Stress
Trauma is one of the most consistently documented contributing factors in conversion disorder. A significant proportion of people with FND report histories of physical abuse, sexual abuse, emotional trauma, or significant adverse childhood experiences. The mechanisms connecting trauma to FND are not fully understood, but research consistently suggests that unprocessed traumatic experiences can disrupt the functional integrity of brain networks involved in motor and sensory regulation.
Acute psychological stress — a significant life event, a sudden loss, a period of extreme emotional pressure — can also trigger conversion disorder episodes or exacerbate existing symptoms, reflecting the sensitivity of functional neurological processing to psychological state.
Predisposing Factors
Not everyone who experiences trauma develops conversion disorder. Research identifies several factors that appear to increase vulnerability — including prior neurological conditions or injuries that create a template for functional symptoms, dissociative tendencies, heightened physiological reactivity to stress, and the presence of other somatic or psychiatric conditions.
The Misdiagnosis Journey
One of the most significant features of conversion disorder is how frequently it is misdiagnosed — and how much harm that misdiagnosis causes. Many people with FND spend months or years in neurological investigation, receiving inconclusive test results, inappropriate treatments for epilepsy or other conditions, and the implicit or explicit suggestion that their symptoms are fabricated or exaggerated.
The average time between symptom onset and correct diagnosis of conversion disorder is measured in years in most research — with significant financial, occupational, and psychological costs accumulating during that period. If you have received an FND or conversion disorder diagnosis after a long medical journey, the frustration and distress of that experience is a clinically important part of your history — and one that effective treatment acknowledges directly.
How Conversion Disorder Affects Daily Life
The functional impairment of conversion disorder is real and can be profound.
Physical functioning — Depending on symptom type, conversion disorder can significantly affect mobility, independence, and the ability to perform daily activities. Motor symptoms including weakness and gait disturbance can require assistive devices. Non-epileptic seizures can prevent driving and create safety concerns. Sensory and visual symptoms can affect the ability to work and navigate daily environments.
Occupational impact — Many people with conversion disorder experience significant disruption to employment — through inability to perform job functions during symptomatic periods, through the unpredictability of symptom presentation, or through the extended time in medical investigation that delays appropriate treatment and return to function.
Psychological wellbeing — The psychological burden of living with a misunderstood and frequently dismissed condition is significant. Depression, anxiety, and the demoralization of a long diagnostic odyssey compound the functional impact of the neurological symptoms themselves. Co-occurring depression and anxiety are present in the majority of people with FND and require direct clinical attention.
Relationships and social functioning — The unpredictability of conversion disorder symptoms, combined with the difficulty of explaining a condition that others often misunderstand as psychological fabrication, produces isolation and relational strain that further affects wellbeing and recovery.
Conversion Disorder Treatment at Friendly Recovery Center
Effective conversion disorder treatment requires a multidisciplinary approach that addresses both the functional neurological symptoms and the psychological, trauma-related, and emotional factors maintaining them. Neither purely neurological management nor purely psychological treatment in isolation produces the most complete results.
Psychoeducation — The Essential First Step
One of the most important and most evidence-supported components of conversion disorder treatment is thorough, compassionate psychoeducation — helping the person with FND understand what the condition is, how it develops, and why the brain-based functional model explains their symptoms more accurately than either structural neurological disease or psychological fabrication.
Research consistently shows that accurate understanding of the FND model — delivered by a clinician who takes the symptoms seriously and explains the neurobiological mechanism clearly — produces symptom improvement in a significant proportion of people, sometimes before any other treatment has begun. The “graceful pathway to improvement” that psychoeducation creates — allowing symptoms to improve as functional brain processing normalizes — is itself a therapeutic mechanism.
Cognitive Behavioral Therapy (CBT)
CBT for conversion disorder addresses the thought patterns, behavioral responses, and emotional processing patterns that maintain functional disruption. This includes challenging the catastrophic interpretations of symptoms that increase physiological arousal and worsen functional disruption, addressing the avoidance behaviors that prevent functional recovery, and developing more adaptive responses to the emotional and stress-related triggers that precipitate episodes.
According to research cited by Cleveland Clinic, CBT is among the most evidence-supported psychological treatments for FND — with randomized controlled trials demonstrating significant improvement in functional symptoms, quality of life, and daily functioning.
Trauma-Informed Therapy and EMDR
For the significant proportion of people with conversion disorder who have trauma histories, trauma-informed treatment is a critical component of comprehensive care. Processing the traumatic experiences that may have disrupted functional brain network integrity — safely and at an appropriate pace — addresses the root psychological conditions contributing to FND rather than managing symptoms in isolation.
Eye Movement Desensitization and Reprocessing (EMDR) is one of the most evidence-based approaches for trauma processing and has shown promising results specifically in FND populations — addressing the traumatic material held in the nervous system that standard talking approaches may not fully reach.
Acceptance and Commitment Therapy (ACT)
ACT helps people with conversion disorder develop a different relationship with their symptoms — reducing the struggle against symptoms that paradoxically amplifies functional disruption, and reconnecting with valued activities and life domains despite the presence of symptoms. ACT is particularly effective for the demoralization and loss of identity that the FND journey frequently produces.
Mindfulness and Nervous System Regulation
Mindfulness and body-based approaches that support nervous system regulation address the physiological dimension of FND — building the capacity to regulate the stress response and autonomic arousal that contribute to functional brain disruption. For people with conversion disorder, mindfulness is not about relaxation as a general goal but about developing specific capacity to interrupt the dysregulation cycles that precipitate symptomatic episodes.
Coordination With Physical and Neurological Care
Effective conversion disorder treatment at the outpatient mental health level typically involves coordination with the neurologist or physical therapist who has been involved in the person’s care. Physical therapy specifically adapted for FND — focusing on normalizing movement patterns rather than treating structural injury — is an important adjunct to psychological treatment for many people with motor symptoms. We work collaboratively with your existing medical providers to ensure that psychological and physical rehabilitation are aligned.

Frequently Asked Questions About Conversion Disorder
-
Is conversion disorder real or is it psychological?
Both — and the distinction between "real" and "psychological" is part of what makes this condition so poorly understood. Conversion disorder produces genuine neurological symptoms that are involuntary and not consciously manufactured. The mechanism producing those symptoms is functional and psychological rather than structural — meaning it involves disrupted brain network processing rather than anatomical damage. Real and psychological are not opposites. Psychological processes produce real physical effects. The symptoms of FND are as real as the symptoms of any neurological condition.
-
My neurologist says nothing is structurally wrong. Does that mean it's all in my head?
No — and this framing has caused enormous harm to people with conversion disorder. "Nothing structurally wrong" means the neurological hardware is intact — not that the symptoms are fabricated or imaginary. Functional disruption in how the brain processes and transmits neurological signals produces real symptoms through a mechanism that standard neurological testing is not designed to detect. A correct FND diagnosis is not an absence of diagnosis. It is a specific and accurate explanation of what is producing your symptoms.
-
Can conversion disorder be cured?
Recovery from conversion disorder is possible — and early treatment significantly improves outcomes. Research suggests that a significant proportion of people with FND experience substantial improvement or full remission with appropriate multidisciplinary treatment. Recovery is not always linear, and some people manage ongoing symptoms rather than achieving complete resolution — but meaningful improvement in functioning and quality of life is achievable for most people who engage with treatment.
-
What is the difference between conversion disorder and non-epileptic seizures?
Non-epileptic seizures (also called psychogenic non-epileptic seizures or PNES) are one of the most common presentations of conversion disorder. They are seizure-like episodes that are not associated with the electrical brain activity of epilepsy — they are functional rather than epileptic in origin. PNES are frequently misdiagnosed as epilepsy and inappropriately treated with anticonvulsant medications before the functional nature is identified. Treatment for PNES is psychological — not anticonvulsant.
-
Do I still need to see a neurologist if I am receiving psychological treatment?
Yes — multidisciplinary care is the most effective approach for conversion disorder. Continued coordination with your neurologist, and in many cases with a physical therapist specializing in FND, alongside psychological treatment produces the most complete results. We work collaboratively with your existing medical team.
You Deserve Care That Understands What This Actually Is
Conversion disorder may be the condition most in need of a clinical team that begins from a position of belief — belief that your symptoms are real, that your experience is valid, and that the long journey to reach an accurate diagnosis was not a sign that nothing was wrong but a sign that the right framework had not yet been applied.
That framework exists. The treatment works. And the path forward is clearer than the years of neurological investigation may have suggested.
