Functional Neurological Disorder: Diagnosis

The Government recognises the importance of ensuring that people with neurological symptoms receive an accurate and timely diagnosis. Clearer diagnostic pathways and improved clinical understanding are key to improving earlier recognition and reducing misdiagnosis of conditions like functional neurological disorder (FND).

The National Institute for Health and Care Excellence (NICE) guideline, Suspected neurological conditions: recognition and referral, reference code NG127, sets out the symptoms commonly associated with FND and the recommended referral pathways for suspected cases, helping clinicians identify positive diagnostic signs rather than relying on a diagnosis of exclusion.

NHS England ensures that integrated care boards (ICBs) follow NICE guidance through a combination of statutory oversight frameworks, annual performance assessments, and local clinical governance requirements.

NICE’s Clinical Knowledge Summary on FND offers further practical advice for clinicians in both primary and non‑specialist care on the diagnosis and management of the condition, supporting more consistent recognition across the system.

ICBs are responsible for commissioning services that meet the needs of their local populations. This includes ensuring appropriate assessment, referral, and support arrangements are in place for people presenting with symptoms consistent with FND, informed by national guidance.
