Experience of Clinical Application of the Method of Integrated Graphic Geometrical Logarithmic Evaluation of Cognitive Functions

Abstract

Objective: Develop and evaluate the effectiveness of the method of integrated graphical geometric logarithmic evaluation of cognitive functions. Methods: The developed method consists in evaluating three indicators of the radar chart: the risk of developing and progressing cognitive impairment, cognitive deficits and expressions emotionally behavioural disorders. The method is tested on 30 subjects of the acute cerebral circulation disturbance during the last six months. Based on the clinical picture, allocated three groups of comparison. In the first group, there were 11 people who had a left middle cerebral artery (MCA) ischemic stroke; the second group consisted of 12 people who had a right MCA ischemic stroke; in the third group, there were 7 people who had a hemorrhagic stroke. The control group was represented by 23 practically healthy young age subjects. Results: It was shown that the less contribution to the development of cognitive impairment in the early recovery period after a hemorrhagic stroke is made by postponed diseases of the musculoskeletal system and head trauma, thyroid gland pathology, and burdened patient’s history of cognitive disorders. The minimal risk from the position of cognitive impairment development in patients in the early recovery period of the right MCA ischemic stroke is the presence in the history of diseases of the musculoskeletal system and pathological conditions associated with cognitive disorders in relatives. The least risk of the developing cognitive impairment in the early recovery period in patients who have had the left MCA ischemic stroke associated with concomitant thyroid gland disease. For theese patients hallucinatory spectrum disorders, abnormal physical activity, sleep and appetite disorders were characterized in the early recovery period. For patients who have had a hemorrhagic stroke and right CMA ischemic stroke, depressive disorders were characterized. Conclusion: The developed method is a convenient and effective tool for visual diagnosis of the risk of development and progression of cognitive impairment, assessment of the severity of cognitive deficit and associated emotional-behavioural disorders.
