ESA for Functional Neurological Disorder (FND): How to Describe Your Limitations on the WCA
Updated June 2026 - Based on current WCA descriptor framework
Functional neurological disorder (FND) is a condition in which the nervous system is not working properly even though the structure of the brain and nerves looks normal on a scan. It can cause non-epileptic or dissociative seizures, functional limb weakness or paralysis, tremor, walking and balance problems, sensory disturbance, and cognitive symptoms such as brain fog and memory difficulty. The symptoms are genuine, often severe, and frequently unpredictable. A key difficulty for claimants is that "normal scans" are sometimes wrongly taken to mean there is nothing wrong, when in fact FND is a positive diagnosis made by a neurologist.
The Work Capability Assessment (WCA) does not ask "do you have FND?" - it asks how your condition affects your ability to perform 17 specific work-related activities. To be found to have Limited Capability for Work (LCW), you need 15 points across all 17 activities combined. The physical and mental activities are scored together and added up. Crucially, the WCA assesses the functional effect of your symptoms, not whether a test shows structural damage, so normal scans do not stop you scoring points. For the Support Group, you need to meet at least one Support Group (Schedule 3) descriptor, score 15 on a single activity, or pass the substantial-risk test.
Which WCA Activities Does FND Affect?
FND can affect a wide range of activities because it produces both physical and cognitive symptoms. The activities most relevant are usually:
- Loss of consciousness / consciousness episodes (Activity 10) - non-epileptic and dissociative seizures, blackouts and absence-type episodes are assessed here. See consciousness explained.
- Mobilising (Activity 1) - functional weakness, leg giving way, gait problems and fatigue affect how far and how reliably you can move. See mobilising explained.
- Standing and sitting (Activity 2) - difficulty maintaining a position because of weakness, tremor or dizziness. See standing and sitting explained.
- Manual dexterity (Activity 5) - tremor, functional weakness or loss of sensation in the hands affects fine tasks.
- Learning tasks (Activity 11) - cognitive symptoms and brain fog can make it hard to learn and retain new tasks.
- Initiating and completing personal action (Activity 13) - fatigue, dissociation and concentration problems can stop you starting, planning or finishing everyday tasks.
- Getting about - anxiety and the risk of an episode in public can prevent getting to places.
Remember, points from ALL activities are added together. Even scoring 6 points each on just three activities gives you 18 points, comfortably over the 15-point threshold. Because FND mixes physical and cognitive symptoms, a well-described claim can often draw points from both the physical and the mental activities at once.
How FND Maps to Specific Descriptors
Within each activity, the WCA uses a set of graded descriptors, and only the single highest descriptor you meet in that activity counts towards your total. The aim is to find the descriptor that genuinely reflects your everyday reality.
- Consciousness - the descriptors look at how often episodes happen. Frequent episodes at least once a week score the top points and can put you into the Support Group, while less frequent episodes still score. Both involuntary seizures and dissociative episodes where you lose awareness or control are relevant here.
- Mobilising - if you cannot reliably and repeatedly mobilise even a short distance, such as 50 metres, without stopping because of functional weakness or fatigue, you score the higher points.
- Manual dexterity - tremor or weakness that stops you doing fine tasks like using a pen or keyboard with either hand can score points here.
- Personal action and learning tasks - cognitive symptoms can mean you need prompting to start or complete tasks, or cannot learn a moderately complex task, both of which score.
For a fuller breakdown of how points are graded, see our guide to the WCA descriptors and the complete WCA guide.
Good Days, Bad Days and the Reliability Test
FND is one of the most unpredictable conditions there is. Symptoms can shift from hour to hour, an episode can strike without warning, and stress or tiredness can make everything worse. The WCA has to take this variability into account through what is known as the reliability test.
To be counted as able to do an activity, you must be able to do it reliably, repeatedly, safely and within a reasonable time, and for the majority of the time. If you can walk on a good day but your legs give way without warning, you cannot mobilise safely or reliably. If you can do a task once but a seizure or wave of fatigue then stops you repeating it, you should not be treated as able to do it. Unpredictability itself is a barrier to work: a job needs you to perform dependably, day after day, and a condition that can stop you at any moment without notice prevents that.
How to Describe FND on the ESA50/UC50 Form
The biggest mistake claimants with FND make is describing the condition in medical terms, or relying on the diagnosis alone, rather than describing the work-related effects. The WCA does not care that scans were normal - it cares about what you cannot do reliably, repeatedly and safely in a workplace context.
When completing your ESA50 or UC50 form, work through each activity and give concrete examples. For seizures, write how many you have in a typical week, whether you get any warning, whether you lose awareness or control, and how long recovery takes. For weakness, write how far you can walk before your leg gives way and how often that happens. Make clear that FND is a positive neurological diagnosis and that the symptoms are real, so normal test results are not misread. Think about an 8-hour working day, 5 days a week.
For more on the assessment itself, see what to say at your WCA assessment.
Support Group (LCWRA) for FND
The Support Group, called LCWRA in Universal Credit, is for people who are not expected to do any work-related activity. There are three main routes to it with FND.
First, you can meet a Schedule 3 descriptor, for example frequent loss of consciousness, or being unable to mobilise more than a short distance. Second, you can score 15 points on a single activity, which frequent non-epileptic seizures or severe functional weakness can reach. Third, you can qualify through the substantial-risk rule (Regulation 35 ESA, Regulation 40 UC), if going to work or doing work-related activity would put your own or someone else's health or safety at substantial risk - for example because unpredictable collapses or seizures would be genuinely dangerous in a workplace or on the way there.
A letter from your neurologist or GP that spells out this risk and the unpredictability in writing carries real weight with the decision maker. See how to qualify for the Support Group and our note on the Work-Related Activity Group for the difference between the two.
Tips for Your WCA with FND
- Always describe limitations in work-related terms, and never let "normal scans" stand as the headline
- Stress the unpredictability - episodes and flares that strike without warning are a real barrier to work
- Think about reliability - can you do each activity dependably, every day, for a full working day, and repeat it?
- Record seizure frequency, warning, loss of awareness and recovery time for the consciousness activity
- Describe your worst typical day, not your best
- Make clear FND is a positive diagnosis and the symptoms are genuine and disabling
- Get supporting evidence that mentions specific work-related limitations, not just the diagnosis
How much could your ESA be worth?
The amount depends on whether you reach the 15-point threshold for Limited Capability for Work, and whether you qualify for the Support Group (LCWRA). As a rough starting point, enter your main condition below to see the kind of figure a successful claim can reach. It is only an estimate - your real award depends on how the Work Capability Assessment scores your difficulties across the 17 activities.

Frequently Asked Questions
Can you get ESA for functional neurological disorder?
Yes, you can claim ESA or Universal Credit on the grounds of functional neurological disorder (FND), even though scans are usually normal. The symptoms are genuine and disabling, and the Work Capability Assessment looks at how they affect your ability to carry out 17 work-related activities. A successful claim depends on showing how non-epileptic seizures, functional weakness, tremor and cognitive symptoms limit what you can do reliably, repeatedly and safely, not on the test results themselves.
How many WCA points can FND score?
FND can score across several activities, most often consciousness episodes from non-epileptic seizures, mobilising, standing and sitting, manual dexterity, learning tasks and personal action. You need 15 points in total across all 17 activities to be found to have Limited Capability for Work, and physical and mental points are added together. Only the single highest-scoring descriptor in each activity counts towards your total.
How do I qualify for the Support Group with FND?
The Support Group (LCWRA on Universal Credit) is separate from the 15-point test. You can reach it by meeting a Schedule 3 descriptor, by scoring 15 points on a single activity such as consciousness, or through the substantial-risk rule if going to work would put your health or safety at substantial risk, for example because of unpredictable collapses or seizures. A neurologist or GP letter that explains this risk in writing carries real weight with the decision maker.
Does FND count for ESA even though my scans are normal?
Yes. FND is a recognised condition in which the nervous system is not working properly even though structural scans look normal. The WCA assesses the functional effect of your symptoms, not whether a scan shows damage. Make sure your form and evidence make clear that FND is a positive diagnosis and that the symptoms are real and disabling, so that normal test results are not wrongly read as meaning there is no problem.
How should I describe non-epileptic seizures on the ESA50 form?
Describe how often the seizures or dissociative episodes happen, how long they last, whether you lose awareness or control, and how long recovery takes. Frame it around an eight-hour working day. If you have warning before an episode it is relevant to the consciousness activity, and so is the unpredictability. Explain what you cannot safely do because an episode could happen at any time, and how often episodes occur in a typical week.
What evidence helps an FND ESA claim?
Useful evidence includes neurology letters confirming the FND diagnosis, clinic and physiotherapy reports, records of non-epileptic seizures, fit notes, and a personal seizure or symptom diary showing frequency and recovery time. Ask your GP or neurologist to describe the functional impact on tasks and the unpredictability of symptoms, rather than simply confirming the diagnosis or that scans were normal.
What if my ESA claim for FND is refused?
If you score too few points or are placed in the wrong group, you can challenge the decision by asking for a Mandatory Reconsideration, and then appealing to an independent First-tier Tribunal if it is still refused. FND claims are often refused because normal scans are misread as meaning there is no disability, so a reconsideration that stresses the functional effect and the unpredictability of symptoms is often where a weak first decision can be turned around.

Strong evidence is crucial for a successful WCA. For FND, gather:
- Neurology letters confirming the FND diagnosis as a positive diagnosis
- Clinic, physiotherapy and occupational therapy reports describing functional limitations
- Records of non-epileptic seizures or dissociative episodes
- Fit notes or med3 certificates
- A personal seizure or symptom diary showing frequency, triggers and recovery time
Ask your GP or neurologist to specifically mention how FND affects your ability to perform work-related tasks and how unpredictable the symptoms are, not just the diagnosis itself. Our guides to the ESA evidence checklist and the medical evidence letter explain what good supporting evidence looks like.
What if You're Rejected?
If you score 0 points or are placed in the wrong group, you should challenge the decision. With FND, the most common reason claims fail is that normal scans are misread as meaning there is no disability, or that limitations are not described in work-related terms - which is exactly what ESAexpert helps you with.
