ICD-10 mild cognitive disorder following meningitis due to neurosarcoidosis.

We report the case of a patient referred to our department with the diagnosis of conversion disorder, who ultimately proved to have neurosarcoidosis presenting with mild cognitive disorder. Despite the criticism of mild cognitive disorder as a diagnostic entity, our patient met the criteria for it. The reported case exemplifies the difficulties in classifying mild cognitive deficits in patients suffering from brain diseases without major morphological damage.
