Very rare disease, expected to be misdiagnosed as psychiatric. I admit I would (neurologist here) But you were luckily treated by an excellent neurologic center.

The lesson learned is that there are rare diseases (<1/10.000-100.000) but as they are so many, they form an important minority next to common ones (1/100-1000). Just don't forget them when data don't fit well. Such estimations is a hard dexterity of doctors that cannot be rivalled by AI.
