[Apraxia disorders in elderly patients with non-stroke chronic brain ischemia].

The study aimed at providing qualitative and quantitative evaluation of apractic disorders in 60 elderly patients (mean age of 75.0 +/- 0.78 years) with non-stroke chronic vascular brain disease (NS CVBD). Apractic disorders were obligatory syndromes in patients with stage 2-3 NS CVBD. Kinetic and regulator apraxia were most prominent forms according to Luria's neuropsychological analyze. Apraxia is associated with the severity of the disease. Kinetic and regulator apraxia were components of frontal lobe syndrome presented by specific mental and speech disturbances and frontal lobe gait disorders. The results may be used in differential diagnosis between NS CVBD in elderly and another type dementias, especially dementia occurred in patients with Alzheimer's disease.
