A total of 52 patients with Parkinson's disease (PD), 11 with presumptive Alzheimer's disease (AD), and 20 healthy subjects were studied; subjects were aged 55-74 years. Neurological symptoms were assessed quantitatively, and the state of higher mental processes were evaluated using the Luriya method. A number of memory tests were also used. These studies(More)
A total of 88 patients with progression of Parkinson's disease (PD) were studied.

Severity of cognitive impairment increased simultaneously with severity of movement disorder. Patient's(More)
Frequency of clinical and psychological peculiarities of moderate (mild) cognitive impairment (MCI) in cerebral vascular insufficiency (CVI) was studied in 42 patients, mean age 67.7 +/- 7.7 years. Along with neurological examination, a battery of psychiatric and neuropsychological scales and tests was used. MCI was diagnosed in 28 (66.7%) patients. In 20(More)

The paper addresses use of cognitive event-related potential P300 to verbal and nonverbal stimuli with an assessment of interhemispheric asymmetry(More)
