One of the most frequently asked questions by people diagnosed with FND is: “Does this count as a disability?”
The short answer: it depends. The long answer: it depends on the country, the legal system, and the functional impact on your life.
What does the law say?
In Portugal, FND can be recognized as a disability if it causes a significant and long-lasting limitation in daily activities. The Multi-Purpose Medical Certificate of Disability (AMIM) system assesses the degree of disability based on functional impact—not on the diagnosis.
In the United Kingdom, the Equality Act 2010 protects people with FND as long as the condition has a substantial and long-term effect on daily activities.
In the United States, the Social Security Administration (SSA) evaluates each case individually. FND is not automatically listed, but it may qualify if the symptoms prevent the person from working.
What Really Matters
More important than the legal label is the actual impact. FND can be just as disabling as multiple sclerosis—with the difference that it does not show up on imaging tests.
If FND affects your ability to work, drive, or perform daily tasks, seek specialized legal guidance. Document your symptoms, request detailed medical reports, and don’t give up at the first “no.”
See the complete guide to FND for more information on diagnosis and treatment.
How to Document Functional Impact
For medical, workplace, or legal purposes, documentation is usually strongest when it describes function, not only diagnosis. Instead of writing only “I have FND”, note concrete examples: how often you fell this month, how long you can stand, whether you can drive, which tasks you have to stop, which adjustments help, and which symptoms appear under stress or fatigue.
Reports from a neurologist, physiotherapist, occupational therapist, and psychotherapist can build a fuller picture. A simple diary also helps: date, main symptom, duration, likely trigger, impact on daily life, and recovery. This does not replace professional assessment, but it organizes evidence and prevents you from relying only on memory during appointments, workplace conversations, or benefit reviews.
