Abstract:
<p>BACKGROUND: Hypertension and HIV are salient risk factors for cerebral small vessel disease and neurocognitive impairment, yet the effects of hypertension on neurocognitive performance in persons living with HIV remain poorly understood. This is the first study to examine the longitudinal associations between blood pressure, hypertension, and pulse pressure with neurocognitive performance in persons living with HIV.SETTING: New York City.METHODS: Analysis of medical, neurocognitive, and virologic data from 485 HIV+ participants collected by the Manhattan HIV Brain Bank, a prospective, observational, longitudinal study of neuroHIV. A series of multilevel linear growth curve models with random intercepts and slopes were estimated for blood pressure, hypertension status, and pulse pressure to predict change in neurocognitive performance.RESULTS: The baseline prevalence of hypertension was 23%. Longitudinal change in diastolic and systolic pressure were associated with 10.5-second and 4-second increase in Grooved Pegboard Test non-dominant hand performance, respectively. Longitudinal change in diastolic blood pressure was also associated a .3-point decline in correct categories and 3-point increase in perseverative responses and total errors on the Wisconsin Card Sorting Test. Increasing odds of prevalent and/or incident hypertension was associated with a .1-point decrease in correct categories and a .8-point increase in total errors on the Wisconsin Card Sorting Test. There was no association between pulse pressure and neurocognitive performance.CONCLUSIONS: Results indicate linear longitudinal relations for blood pressure and hypertension with poorer neurocognitive test performance, particularly in psychomotor and executive functions in persons with HIV.</p>
