The Goal of the Exam
The neurological examination is the most critical part of your diagnostic journey. Unlike a blood test or an MRI, which look at the "hardware," the neuro-exam allows the doctor to test your "software" in real-time.
Detailed History
The doctor will ask about how symptoms started, if they fluctuate, and if focus or stress affects them. This 'story' is often the first clue to an FND diagnosis.
Physical Testing
You will be asked to perform specific movements. The doctor is looking for 'positive signs'—evidence that your brain pathways are still working even when a limb feels weak.
Common Clinical Tests
During the exam, your neurologist might perform tests that feel unusual. These are designed to "bypass" the FND software glitch and access your brain's automatic programs.
- Hoover's Sign: Testing the strength of one leg while you focus on the other.
- Entrainment Test: Seeing if a tremor in one hand changes when you tap a rhythm with the other.
- Gait Observation: Watching you walk at different speeds or while performing a mental task (like counting backwards).
The Paradox of Testing
How to Prepare
Coming to the exam prepared can help your neurologist provide a more confident diagnosis:
- List your symptoms: Note when they happen and what makes them better or worse.
- Videos: If you have intermittent symptoms (like seizures or tremors), having a video can be extremely helpful for the doctor.
- Medication list: Bring everything you are currently taking.
