Abstract
Introduction. Chronic cerebral ischemia (CCI) is considered a syndrome that develops as a result of a slowly progressive reduction in cerebral blood flow. This reduction occurs due to the gradual accumulation of ischemic and secondary degenerative changes in the brain, which are caused by repeated ischemic episodes resulting from the development of atherosclerosis and arterial hypertension. These changes lead to impairment of brain functions, manifested by progressive neurological, neuropsychological, and mental disorders.
The aim. To analyze the problems of pathogenesis, diagnosis, and treatment of CCI from the sources of modern literature in order to optimize the treatment of this group of patients.
Materials and methods. Bibliosemantic, comparative and method of system analysis.
Results. The pathogenetic mechanisms underlying CCI remain controversial due to the heterogeneity of causes and the complexity of the neuropathology associated with the disease. However, one common reason that can be named is dysregulation of cerebral blood flow, that results in chronic cerebral hypoperfusion, which can lead to the development of vascular cognitive impairment and dementia. Detection of biological markers in the patients' blood in combination with neuropsychological testing, neurophysiological (CEP P300, EEG) and neuroimaging (CT, MRI, Doppler Ultrasound of the head and neck) methods, which confirms the morphological substrate of vascular disease (leukoareosis, focal changes, multi-infarct condition, cerebral atrophy) and provides the possibility of choosing an effective pathogenetically-justified treatment.
Conclusions. The rating of effectiveness of treatment in CCI is complicated considering difficulties in the selection of the efficiency criteria due to the significant differences in the methodology and research formats, as well as problem of a significant medication-related burden in the case of comorbidities. In this regard, the main direction in therapy is combined neuroprotection, which allows to optimize the possibilities of this strategy and to increase its clinical significance in angioneurology.
