For the Person With FND
Having FCD should not close the door on other explanations or treatments. Poor sleep, pain or difficulty hearing can make a conversation harder to follow, while medication effects or another illness may also matter. Sorting this out is a shared clinical task, not something you must diagnose alone.
These conditions are not automatically FCD
Migraine, chronic pain, fatigue, poor sleep, ADHD, mood disorders, medicine effects, sensory impairment and neurological illness may independently cause cognitive symptoms, coexist with FCD, or worsen an established functional pattern. They are not components of FCD simply because thinking becomes harder when they are present.
For example, treatment that makes migraine less frequent might leave more days when reading is manageable. That matters, even if another cognitive difficulty remains. Improvement would not show that migraine caused FCD—or that every previous lapse was functional. Keep both questions in the care plan. See Module 11: Pain, Migraine, Fatigue, and Sleep. [1][2]
A manageable way to begin
- Bring a short list of what has changed, your current medicines and supplements, and the tasks affected.
- Ask about relevant contributors: sleep, pain, fatigue, migraine, hearing or vision, mood, ADHD and other neurological or medical conditions.
- Agree which issue to address first, who will help and when it will be reviewed.
- Keep a brief note of useful changes and adverse effects. A prescriber should guide medication changes; do not abruptly stop treatment using this page.
Keeping the approach helpful
Treating a contributor may improve part of the difficulty without resolving everything. Anxiety and depression deserve care when present, but neither is required for FCD. New or progressive problems should not automatically be attributed to the existing diagnosis. [1][2]
During a familiar flare
If a familiar flare follows poor sleep or migraine, use your established plan and reduce avoidable demands. A substantially different episode needs assessment. Do not keep increasing cognitive exercises while an untreated contributor is making them intolerable.
When to seek assessment
Sudden new confusion, altered consciousness, or cognitive difficulty with new weakness, speech change, severe headache, fever, a seizure or head injury needs urgent medical assessment. New difficulty recognizing highly familiar people, progressive loss of familiar knowledge, major visual-spatial change, progressive decline, getting lost in familiar places, unsafe medication or financial errors, or a marked change from your usual pattern also needs review. Pause safety-sensitive activities when you cannot manage them safely. Existing FCD does not explain every new symptom.

With permission, help prepare a concise list or attend a review. Describe concrete changes without deciding their cause. Support access to hearing, sleep or other services and help clarify who is coordinating care.
During a familiar flare, use one speaker and one idea at a time. Give processing time and offer the person’s usual aids. Preserve dignity and choice; ask before taking over. If the pattern is new or severe, follow the medical plan instead of continuing a recovery exercise.

For Clinicians and the Care Team
Review the differential and contributors proportionately, using history, examination and indicated investigations. Include medication/substance effects, sleep disorders, sensory impairment, mood, neurodevelopmental conditions and neurological disease. Avoid both endless low-yield investigation and diagnostic overshadowing. Record reassessment thresholds and an accountable follow-up plan. [1][2]
Agree a written next step, accessible prompts and a review point. Assess symptom burden, daily function, support needs and adverse effects. FCD is a positive clinical diagnosis; normal tests alone, a good moment or the response to an exercise cannot establish it. Practical assistance should continue when symptom improvement is limited. See the paired diagnostic page.
