[Vascular ischemic dementia].

Observations are reported of the course and other interrelations between clinical pattern and computer tomography results in 36 patients with vascular ischaemic dementia. Attention is called to the frequency of transient dementia-like disturbances following stroke and to the importance of the middle gyrus of the left frontal lobe in the development of dementia manifestations. In cases with slow progression of dementia symptoms and only scant neurological signs not infrequently long-standing improvement or even complete remission of dementia symptoms occur which sets them apart from mixed forms of dementia. The problem of the occurrence of isolated dementia syndromes of sudden onset is discussed and for them the term "stroke with dementia" is proposed.
