[Age dynamics of cognitive functions in persons 50-85 years].

The paper presents original study results of cognitive changes associated with aging in the absence of neurodegenerative, vascular and other significant for cognition disorders in period from 50 to 85 years. It was shown that aging is associated with moderate memory decrease predominantly because of retrieval deficit but not acquisition insufficiency. It was also shown that aging is associated with non-severe executive dysfunction (lack of planning and control).

[Chronic cerebral circulatory insufficiency: A clinical case report].

Chronic cerebral circulatory insufficiency (CCCI) is a result of cerebral microangiopathy, most commonly due to uncontrolled hypertension. In this case, the brain is affected due to recurrent silent infarcts and/or microbleedings without clinical manifestations of stroke and chronic brain ischemia. Progressive cognitive impairments with a preponderance of inadequate attention and lower rates of cognitive performance, with impaired planning and control abilities in relative preservation of memory serve as the main manifestation of chronic progressive non-stroke vascular lesion in the brain.
