Abstract
To study clinical characteristics of dementia with Lewy bodies (DLB) depending on neuropsychological, neuroimaging and concomitant cerebrovascular changes as well as on the character of disease onset. Forty-five patients with DLB (25 men and 20 women, men age 72.9±7.2 years, illness duration 2.9±2.2) were studied. The diagnosis was made according to international criteria (McKeith, et al, 2017). MRI, clinical/neurological examination and psychometric scales were used. Clinical, neuropsychological and neuroimaging results reveal the heterogeneity of DLB, which remains poorly investigated. An analysis of the clinical picture, cognitive profile, neuropsychiatric changes and MRI results identified three subtypes of DLB course: 1) typical; 2) with early psychotic manifestation; 3) atypical (mixed). This approach may improve the diagnosis of DLB, prognosis of disease course and treatment effectiveness.
