Motivation as a factor affecting the efficiency of cognitive processes in elderly patients with hypertension

Abstract

The main purpose of the present study was to assess the role of motivation in the effective cognitive activity of elderly hypertension (HTN) patients provided with antihypertensive treatment; 25 patients with HTN took part in the study, stage 1-2; their mean age was 67.6±6.1. The psychological examination program embraced a quantitative measurement of intelligence quotient (IQ) with the Wechsler Adult Intelligence Scale, and an investigation into the qualitative features of their cognitive processes, applying a pathopsychological study procedure (Zeigarnik, 1962, 1972) and the principles of psychological syndrome analysis (Vygotsky-Luria-Zeigarnik school). The results showed that within the psychological syndrome structure of cognitive disorders in HTN patients, the leading part is played by two syndrome-generating factors: a neurodynamic factor and a motivational factor. The patients with reduced motivation would achieve poor general test results, if compared with the group of highly motivated participants. A correlation analysis of the data revealed the interconnection between frequency disturbances in motivation and the frequency in occurrence of various signs of cognitive decline, such as low efficiency in memorization and delayed recall, as well as lower IQ test results. The data provide a strong argument to support the hypothesis that motivation is of particular importance as a factor in the generation of cognitive disorders in HTN patients.
