Functional Neurologic Disorder (FND) in Children and Young Adults: Symptoms, Causes, and Treatment
Functional Neurologic Disorder (FND) is a condition that affects how the brain sends and receives signals throughout the body. Although the symptoms can appear similar to neurological diseases, they occur without structural damage to the brain or nervous system. Instead, the problem lies in how the brain functions and communicates with the body.
Functional Neurologic Disorder is increasingly recognized by neurologists and mental health professionals, particularly in children, adolescents, and young adults. While the symptoms can be frightening and disruptive, research shows that many young people improve significantly with appropriate treatment, especially psychotherapy and supportive care.
At Ezer Psychotherapy, we provide compassionate, evidence-based therapy for adolescents and young adults experiencing conditions like FND.
What Is Functional Neurologic Disorder?
Functional Neurologic Disorder (FND) occurs when the brain has difficulty controlling movement, sensation, or other neurological processes. Unlike neurological diseases that involve structural damage to the brain, FND affects how the brain functions rather than how it is physically structured.
In simple terms, the brain’s “software” is temporarily malfunctioning even though the “hardware” is intact.
FND may also be referred to as:
Functional neurological symptom disorder (or Functional Neurologic Symptoms)
Conversion disorder
Functional seizures, psychogenic non-epileptic seizures (PNES), non-epileptic events (NEEs)
It is important to understand that FND symptoms are real and involuntary. Individuals are not faking symptoms or imagining them. The condition reflects genuine disruptions in brain signaling that can be improved with treatment.
Symptoms of Functional Neurologic Disorder in Children and Young Adults
Symptoms of FND can vary widely from person to person and may develop suddenly or gradually.
Common symptoms include:
Movement Symptoms
Tremors or shaking
Weakness in the arms or legs
Difficulty walking or abnormal gait
Muscle spasms or jerking movements
Sensory Symptoms
Numbness or tingling
Vision problems
Hearing changes
Seizure-Like Episodes
Some young people experience episodes that resemble seizures but are not caused by epilepsy. These are sometimes called functional seizures or non-epileptic seizures.
Cognitive and Physical Symptoms
Brain fog or difficulty concentrating
Fatigue
Headaches
Speech difficulties
These symptoms can interfere with school, sports, friendships, and everyday functioning.
How FND Impacts Children, Teens, and College Students
Functional Neurologic Disorder often appears during key developmental stages such as adolescence or early adulthood.
Young people with FND may struggle with:
School attendance or academic performance
Participation in athletics or extracurricular activities
Social relationships
Anxiety and frustration related to symptoms
Feeling misunderstood when medical tests appear normal
Because the symptoms are neurological in nature, many families initially seek medical care from neurologists. Once other neurological conditions are ruled out, treatment often includes psychotherapy and rehabilitation approaches.
What Causes Functional Neurologic Disorder?
There is rarely a single cause of FND. Instead, the condition usually develops due to a combination of neurological, psychological, and environmental factors.
Potential contributing factors include:
Stress or emotional overwhelm
Anxiety or depression
Trauma or adverse life experiences
Physical illness or injury
Academic or athletic pressure
Nervous system dysregulation
Learned physiologic response to specific stimuli
Research suggests that FND involves changes in how the brain processes movement, attention, and body signals. The brain essentially gets “stuck” in an unhelpful pattern of signaling.
The encouraging news is that the brain is highly adaptable, meaning these patterns can change with treatment and practice.
How Psychotherapy Helps Treat Functional Neurologic Disorder
Psychotherapy is a key part of treatment for many children, teens, and young adults with FND. Therapy focuses on improving brain-body communication, regulating the nervous system, and addressing factors that may contribute to symptoms.
1. Education About the Brain–Body Connection
A major component of treatment is helping young people understand how FND works.
Learning that symptoms are real but reversible can reduce fear and help individuals feel more hopeful about recovery.
2. Reducing Stress and Nervous System Dysregulation
Many individuals with FND have nervous systems that are operating in a heightened state of stress or threat.
Therapy may include skills such as:
Emotional regulation
Stress management
Mindfulness and grounding techniques
Body awareness exercises
These approaches help calm the nervous system and improve the brain’s ability to regulate physical symptoms.
3. Treating Anxiety, Trauma, or Emotional Stress
For some individuals, FND symptoms are linked to unresolved emotional stress or anxiety.
Evidence-based therapies can help address these factors, including:
Cognitive Behavioral Therapy (CBT)
Trauma-informed therapy
Family therapy
Skills for managing anxiety and stress
When emotional stress is addressed, many individuals notice improvements in neurological symptoms.
4. Supporting a Gradual Return to Daily Life
Recovery from FND often includes gradually returning to normal activities, such as school, sports, and social engagement.
Therapy helps young people:
Rebuild trust in their body
Reduce avoidance behaviors
Develop coping skills
Increase resilience
This step-by-step approach helps the brain relearn healthy movement and functioning patterns.
The Role of Family Support in FND Recovery
Family involvement is especially important when children or adolescents are experiencing Functional Neurologic Disorder.
Parents can help by:
Validating that symptoms are real
Encouraging gradual engagement in normal activities
Avoiding excessive focus on symptoms
Supporting therapy and treatment recommendations
A supportive environment can significantly improve recovery outcomes.
When to Seek Therapy for Functional Neurologic Disorder
You may want to seek professional support if your child or young adult experiences:
Unexplained neurological symptoms
Seizure-like episodes without an epilepsy diagnosis
Difficulty walking or moving without a medical explanation
Sudden weakness or tremors
Significant disruption to school or daily life
Early treatment can help young people regain functioning and confidence more quickly.
