RESUMO

Hypertension is thought be involved in cognitive decline and in the conversion to dementia among older adults. It is estimated that up to 60% of older adults have hypertension, what makes them more vulnerable to cognitive decline. Objective: The objective of this study was to investigate the relationship between hypertension and cognitive performance in non-demented older adults. Method: The sample was constituted by community dwelling older adults, who were registered at a public health unity, which offers regular home visits by a multidisciplinary health team. Participants were selected from the data bank from an earlier epidemiological study which included all senior citizens residing in Amparo (SP). Following inclusion and exclusion criteria, 80 seniors (men and women over 60) were recruited. 40 reported having hypertension and 40 did not. Both groups were equivalent as to socio-demographic and other health variables including presence of co-morbidities. The cognitive tests included the Geriatric Depression Scale (GDS), the Consortium to Establish a Registry for Alzheimer s Disease (CERAD) neuropsychological battery, the Clock Drawing Test, and Digit Span Forward and Backward. Logistic regression analyses with univariate and multivariate models and cluster analyses were carried out. No significant differences were found between the two groups for cognitive variables. The difference for verbal fluency approached significance (p=0.075). Discussion: Present results may be explained by the high compliance of the studied sample to the antihypertensive drug regimen. Longitudinal studies may be needed to continue to investigate the relationship between hypertension and cognition in aging
