About Functional Neurological Disorder

FND is a condition in which the brain's networks don't function correctly — producing very real neurological symptoms without structural damage showing on scans.

Common symptoms

FND can look different for everyone. Symptoms may fluctuate day-to-day and can affect movement, sensation, cognition and more.

  • Non-epileptic seizures
  • Limb weakness or paralysis
  • Tremor and involuntary movements
  • Gait and balance difficulties
  • Sensory changes and numbness
  • Speech and swallowing issues
  • Cognitive fog and fatigue
  • Chronic pain

Causes & triggers

FND often develops after a physical injury, illness or period of significant stress. The exact cause isn't fully understood, but it involves a disruption in how the brain processes signals.

Diagnosis

FND is a positive diagnosis based on clinical signs — not simply the absence of other conditions. A neurologist experienced with FND can identify it reliably.

Treatment

Multidisciplinary care works best: neurology, physiotherapy tailored to FND, psychological therapies (like CBT), and self-management strategies.

Prognosis

Many people improve significantly with the right support. Early recognition and education are key.
