PIP for Functional Neurological Disorder (FND): The Strategy (2026)
1. What is FND?
Functional Neurological Disorder (FND) is a condition where there is a problem with how the brain sends and receives signals, rather than a structural problem with the nervous system. Common symptoms include tremors, seizures, limb weakness, and cognitive issues.The PIP Challenge: Because FND symptoms can fluctuate wildly and are often triggered by stress or fatigue, DWP assessors often mistake it for a "psychological" issue rather than a functional disability.
2. Proving the Functional Impact
The secret to a successful FND claim is describing the unpredictability of your symptoms using the "Reliability" criteria.- Safely: If you have non-epileptic seizures or sudden limb weakness, you cannot cook or wash safely without supervision.
- Repeatedly: If you can walk 50 meters once, but the effort triggers a tremor that lasts for 6 hours, you cannot walk "repeatedly."
- To an Acceptable Standard: If your weakness means you struggle to hold a knife or drop things, you cannot prepare food to an acceptable standard.
3. Dealing with Fluctuating Symptoms
FND is often "intermittent."- The 50% Rule: You should score points if your symptoms affect you for more than half of the days in a month.
- The Strategy: Do not average your symptoms. Describe what happens on your "bad" and "moderate" days. If 4 days a week you cannot leave the house due to leg weakness, you meet the 50% threshold for mobility points.
4. The "Mental Health" vs. "Physical" Distinction
FND is a neurological condition, but it is often influenced by the brain's response to stress.- The Trap: Assessors may try to push you into the "Mental Health" descriptors (Activity 9 and 11) only.
- The Strategy: Insist on the physical impact. If your legs give way, that is a mobility issue (Activity 12). If your hands shake, that is a manual dexterity issue (Activity 1 and 4). You can score in both physical and mental health activities.
5. Essential Evidence for FND
- Neurologist Report: This is your most important document. It should confirm the diagnosis and describe your specific symptoms (tremors, gait, etc.).
- Physiotherapy/Occupational Therapy Reports: These are excellent because they describe your *functional* limitations in a clinical way.
- Seizure/Symptom Diary: Keep a detailed log for 14 days. Note the triggers, the duration of the symptoms, and the "recovery time" needed afterwards.
- Incident Reports: If you have had falls or accidents, document them (even if you didn't go to A&E).
