title: [Thalamic dementia].
abstract: Report with complementary clinical examinations and detailed neuropathological findings of a case of subacute progressing "thalamic dementia", interpreted as combined systemic degeneration of the dorsal and medial thalamic nuclei. For the development of the EEG changes, which were followed from beginning of the disease, a slowly advancing reduction of the function of the meso-diencephalic activating system proved responsible. The inferior olives were symmetrically atrophied and the fasciculus tegmenti centralis was on both sides completely degenerated. It is to be considered that the inferior olives are directly subordinated to the medial thalamic nuclei by the way of the fasciculus tegmenti centralis. In the cerebellum nerve cell groups and fiber bundles, which are closely connected with the reticular system, are degenerated. The systemic medial degenerations of the thalamus belong to the abiotrophies in the sense of Gowers original conception.
