How common is FND?
Contrary to popular belief, FND is highly prevalent. It is estimated that 1 in 3 new patients seen in neurology clinics have symptoms that are partly or entirely due to FND.
Annual Diagnoses
Estimated new cases per year in the UK alone, similar to MS diagnoses.
Reach
FND is diagnosed across all cultures and ethnicities worldwide.
Who does it affect?
FND can affect anyone, but certain demographics show higher rates of diagnosis:
- Gender: While historically associated with females, we now know it affects both genders significantly. In some clusters like PNES, there is a female predominance (3:1).
- Age: Symptoms can appear at any age, including childhood, though the peak onset is often between ages 20 and 50.
- Co-morbidities: Many patients with FND also have other neurological conditions like epilepsy, migraine, or chronic pain.
A Misunderstood Metric
Is FND on the rise?
Increased Recognition
While diagnoses are increasing, this is likely due to better medical awareness and specialized "positive signs" diagnosis rather than a surge in the condition itself. We are finally giving a name to what was previously mislabeled.
Impact on Quality of Life
Statistics indicate that the disability associated with FND is often equivalent to or greater than that of MS or Parkinson's. This emphasizes the need for early diagnosis and multidisciplinary treatment to return patients to functional life.
