ABSTRACT
OBJECTIVES:
An increasing evidence suggests hypertension (HTN) could be linked to cognitive impairment and incident Alzheimer's disease (AD). The precise mechanisms linking HTN and AD are not well-known. The aim of this study was to assess the putative association between HTN and AD.METHODS:
We assessed in patients with AD associations between HTN and demographic and clinical data, vascular risk factors, treatments, APOE genotypes, brain white matter hyperintensities (WMH), and medial temporal atrophy (MTA) in multivariate analysis of covariance.RESULTS:
We studied 92 patients with AD (mean ± SD age 72.12 ± 6.91; women 66.30%). Patients with HTN had significantly worse cognitive and functional status and higher frequency and severity of neuropsychiatric symptoms (P = .010). Magnetic resonance imaging analyzes showed significant increases in WMH (P = .018) and in MTA (P = .012) in patients with AD with HTN compared with those without HTN.CONCLUSIONS:
Neuroimaging burden (MTA and higher degree of severity of WMH) among patients with AD and HTN are associated with the impaired cognitive function and neuropsychiatric symptoms.Key words
