For the Person With FND

Definition

Functional capacity is what you can do in real conditions. Variable function means that ability changes across time or situations. Disability forms and rules use different definitions, so local advice matters.

Illustration: one successful attempt does not answer every question about sustainable function.

If you read only one thing

Describe an ordinary week and a difficult week, not only your best day or worst moment. Include what happens during the task and afterward.

Five parts of a useful example

1. Task: what you were trying to do.
2. Reliability: how often and predictably you can do it.
3. Safety: falls, episodes, mistakes, injury or supervision.
4. Recovery: what happens later and how long it lasts.
5. Support: prompting, equipment, transport, another person or changed conditions.

For example: “I can prepare a simple meal twice some weeks if ingredients are ready and someone is nearby. Standing and sequencing become unsafe on other days, and I may need to lie down afterward.” This is clearer than “I can cook” or “I cannot cook.”

Use records only as much as they help. A short dated example may be enough; constant monitoring can be burdensome. Benefit and accommodation systems differ, and this page is not legal advice.

Research shows that FND outcomes need more than a symptom score and that specialist samples can experience severe disability. Neither study can decide an individual claim. [1][2]

Community experiences for review

Option 1 — unstable walking

“My legs feel awful. They feel disconnected … everything feels like I’m going to collapse.”

— One person’s description of leg function. Read the public source.

Option 2 — prompting for basic needs

“Currently I can barely take care of myself … My partner has to remind me.”

— One person’s account of memory and daily care. Read the public source.

Questions

Which thing can you sometimes do, but not reliably enough for other people to understand the problem?

What does the task cost you afterward that a form or appointment might miss?

One small thing you can do

Write one example using only task — reliability — safety — recovery — support. Ask someone to help type or remember it if needed. Stop if recording symptoms is worsening distress or taking more capacity than it returns.

For Family, Friends, and Other Supporters

With consent, add specific observations: the prompting given, the recovery you saw or why a task stopped. Do not exaggerate, minimize or turn a rare better day into the person’s usual capacity. Let the person decide what private information is shared.

Research quotations for review

Option 1 — Pick et al., 2020

“few well-validated FND-specific outcome measures”

Option 2 — Moss et al., 2026

“significant functional disability”

Describe, do not adjudicate beyond the evidence

Document diagnosis and comorbidities, but make the functional description task-specific: frequency, variability, quality, safety, time, assistance, adaptations and delayed effect. Distinguish patient report, supporter report, examination and inference. A short clinic examination cannot reproduce a full week or every work setting.

Outcome measures can support care but are imperfect and cover different domains. Specialist-cohort findings demonstrate possible severity, not an individual’s eligibility. Avoid stating that fluctuating performance is inconsistency in the everyday sense or evidence of low effort. Give an opinion only within your role and local rules; record uncertainty plainly. [1][2]
