Of intellectual sphere is characterized by impaired as a result of underestimating the generalization task conditions and making impulsive decisions. Unlike Alzheimer's disease, and local lesions of the cerebral cortex to subcortical dementia are not characteristic of amnesia on current events, apraxia, agnosia, and aphasia [13,21,26,40,49]. Descriptions of cognitive impairment in the ED and vascular dementia are broadly consistent with the above-mentioned model ? ? subcortical dementia. However, the presence of cerebral infarctions, or cortical localization of associated neurodegenerative process may modify the clinical picture is very, adding a touch of features characteristic of primary lesions of temporal-parietal regions of the brain. Concomitant neurodegenerative processes, as typically occurs in individuals of older age. The clinical picture of cognitive impairment in this case may more resemble Alzheimer's disease [3,4,13,16,18,41,49]. Clinical features of emotional disorders in the ED most common change in emotional state at DOE is to develop depression. However, as a rule, the severity of depression does not reach the degree of a major depressive episode criteria DSMIV. In the early stages of depression with ED is hypochondriacal traits. Severity of hypochondria, but decreases with the progression of vascular brain disease. The severity of depressive symptoms in ED depends on the stage of disease and severity of neurological disorders. There is also a relationship with the severity of cognitive impairment and dementia: when it says a great manifestation of depression [16]. Quite interesting data on the clinical and neuroimaging comparisons. In TA Yanakaevoy it was shown that the presence and severity of depressive symptoms depend on the severity of focal changes in white matter of the frontal lobes of the brain and neuroimaging evidence of ischemic damage to the basal ganglia. These observations suggest the biological nature of depression in the ED is probably due mainly to the phenomenon of frontal-subcortical disconnection [16]. Diagnosis and differential diagnosis of vascular dementia in the differential diagnosis of vascular and degenerative dementia, primary-a very important role is played by a combination of cognitive impairment and other clinical manifestations of the phenomenon of separation. The latter include pseudobulbar syndrome, oligobradikineziya, apraxia of walking, posture and pelvic disorders. In typical cases, the subcortical nature of cognitive dysfunction and symptoms of depression in conjunction with the above neurological disorders have been reported in an elderly patient with a history of povotornyh stroke and long-existing vascular disease, such as hypertension or cerebral atherosclerosis [3,17,18,35]. An important role in the verification of the vascular nature of cognitive and emotional disturbances are neuroimaging techniques: CT and MRI of the brain. Currently, the diagnosis of vascular dementia is considered illegal without neuroimaging confirmation.
