| Opplysninger | We present an autopsied case of striatonigral degeneration (SND) combined with olivopontocerebellar atrophy (OPCA) with subcortical dementia and hallucinatory state. A Japanese woman without a remarkable family history showed hand tremor at the age of 35 years, followed by bradykinesia, muscle rigidity, orthostatic hypotension, neurogenic bladder and pyramidal signs. No obvious cerebellar symptoms were found. Various antiparkinsonian drugs were administered, but were not markedly effective for the parkinsonism. She developed a mild dementia characterized by mild memory disturbance with preservation of orientation, slowing of thought processes, emotional lability toward sadness, impaired ability to manipulate acquired knowledge and poor calculating, and by the absence of aphasia, apraxia and agnosia. The features in this patient were consistent with those seen in subcortical dementia. She also had auditory hallucinations. MRI revealed hypointense T-2 signals in the putamina and substantia nigra. T-1-weighted MRI demonstrated atrophy of both the pens and cerebellum in addition to atrophy of the putamina and substantia nigra. EEG showed slowing of background activity. She died of cardiac failure at the age of 47. Autopsy disclosed brain stem tegmental atrophy, SND, OPCA and many glial cytoplasmic inclusions in the central nervous system, but well-preseved cerebrum. We discuss the relationship between the psychiatric symptoms and pathologic findings of brain stem tegmentum.
