FND is a real neurological condition
Functional neurological disorder describes genuinely experienced neurological symptoms involving altered nervous-system functioning rather than the structural damage seen in some other neurological diseases. Symptoms can include weakness, movement symptoms, sensory changes or functional seizures.[1][2]
Modern guidance treats FND as a rule-in diagnosis. A clinician looks for positive features on history and examination; the diagnosis should not be made merely because scans are normal, symptoms are unusual, or someone has anxiety or a history of stress.[1][2]
Where trauma fits — carefully
A systematic review and meta-analysis found that stressful life events and maltreatment were more common in people with FND than in control groups. That is a group-level association: it does not mean every person with FND has experienced trauma, or that trauma alone caused an individual’s symptoms.[3]
Clinical reviews explicitly warn against diagnosing FND on the basis of psychological comorbidity or recent stress. Physical illness, injury, migraine and other neurological or medical conditions may also coexist with or precede functional symptoms.[1]
Treatment is individual, not one-size-fits-all
Evidence-informed care begins with a clear, respectful explanation of the diagnosis. Depending on the symptom pattern, treatment may involve specialist physiotherapy, occupational therapy, speech therapy, psychological therapy and management of coexisting conditions. Not everyone responds in the same way.[2]
Trauma-focused work may be appropriate when trauma is present and the person wants to address it. It should not be imposed as a universal explanation or offered in place of neurological assessment and rehabilitation.[1][2]
A note from Sureyya
Lived experienceSureyya’s interest in this subject comes from both counselling practice and her own reported experience of FND. That lived perspective can offer empathy, but it is not scientific evidence and will never be presented as proof that another person’s illness has the same cause or course.
If you have new, changing or unexplained neurological symptoms, seek medical assessment. If symptoms are sudden or severe, use urgent NHS services rather than relying on online information.[1]
Evidence boundary
Evidence about a population does not establish the cause of one person’s symptoms. A guideline, review or study also does not prove that Sureyya’s counselling or a self-guided resource will produce a particular result.
