Neuropsychological deficits in arterial hypertension

Abstract

Sixty subjects with uncomplicated essential hypertension and 60 matched normal subjects were submitted to neuropsychological tests in order to establish whether some impairment of cognitive functions can be evidenced even in those hypertensive subjects that are in this respect asymptomatic on standard examination and interview. The hypertensive subjects obtained significantly poorer results than normotensive subjects on memory, visuo‐motor and performance tests. In the control group, the classic negative correlation pattern between age and scores was observed, while in the patient group this correlation could be confirmed only in a few tests. Subgrouping of patients according to hypertension duration and treatment showed that the impairment of cognitive functions manifested itself very early and did not tend to progress within 6–10 years of hypertension duration.
