Creutzfeldt-Jakob disease mimicking Lewy body dementia - a case report.

Lewy body dementia and Creutzfeldt-Jakob disease are recognized on the basis of certain diagnostic criteria. However, common symptoms such as: dementia, extrapyramidal syndrome, psychotic disorders may cause difficulty to make the correct diagnosis especially in the early stage of the disease. Each of these diseases may have atypical onset.

[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.
