Functional Neurological Disorder (FND)

 
 

What is functional neurological disorder (FND)?

Functional neurological disorder (FND) causes symptoms that appear neurological—like weakness, tremors, seizures, or speech difficulties—but arise from a disruption in how the brain functions, rather than structural damage. It is a real, treatable condition.

“My body wouldn’t do what I wanted it to, and no one could explain why. Getting a proper diagnosis changed everything.”

Different experiences of FND in adults

FND often presents as unexplained symptoms such as limb weakness, non-epileptic seizures, gait disturbances, or visual and speech problems. People may also experience fatigue, chronic pain, brain fog, or emotional distress. These symptoms are often misdiagnosed—or dismissed as “just stress”—leading to frustration, shame, and delayed care.

The condition arises when the brain’s normal communication processes become disrupted, often following physical illness, trauma, or emotional stress. This disruption is real: it can be seen on functional brain scans, even if MRI or CT scans appear normal. FND may coexist with anxiety, depression, or trauma, but it is not “imagined”—and it responds best to a compassionate, evidence-based approach that integrates psychological and physical treatment.

“Helping patients with FND regain control and rebuild trust in their body is deeply rewarding—it restores hope where it was nearly lost.”

Symptoms of functional neurological disorder

  • Weakness or paralysis in a limb
  • Seizures that are not epileptic (dissociative seizures)
  • Speech or voice changes (e.g. stuttering, mutism)
  • Gait abnormalities or difficulty walking
  • Tremors or abnormal movements
  • Blackouts or non-responsive episodes
  • Sensory changes (numbness, tingling, vision problems)
  • Fatigue, brain fog, or memory difficulties
  • Anxiety, low mood, or dissociation
  • Symptoms that worsen under stress or fatigue
Our approach
 

Our approach to treating functional neurological disorder

At Bloomfield Health, we offer specialist assessment and treatment for adults with FND. Our approach is collaborative, trauma-informed, and grounded in the latest neuroscience. We work closely with neurologists to confirm diagnosis, then provide psychological therapies such as cognitive behavioural therapy (CBT), to help restore function and reduce distress. We also support pacing, symptom management, and identity adjustment. You’ll be treated with compassion, respect, and belief in your recovery.

 

Frequently asked questions

Yes. FND is a recognised neurological condition that involves disrupted brain–body communication. It’s real, and it’s treatable.

Causes vary. It may follow physical illness, trauma, or emotional stress, but it can also arise without an obvious trigger.

Diagnosis is made by a neurologist based on positive clinical signs—not by excluding other conditions.

FND is a functional issue, not structural. Brain scans often look normal, even when function is disrupted.

Yes. Therapy addresses the brain’s control systems, helps reduce symptoms, and supports recovery. Physical rehab may also help.

No. FND symptoms are real and involuntary. They are not imagined or consciously produced.

Many people improve significantly with the right diagnosis, understanding, and treatment. Early support improves outcomes.

That’s common. We offer integrated care that addresses psychological and physical aspects together.
