title: Relation of neurocardiovascular instability to cognitive, emotional and functional domains.
abstract: There is bulk of evidence suggesting that blood pressure dysregulation, as low blood pressure (LBP) or hypotension, orthostatic hypotension (OH) and high blood pressure (HPB) or hypertension are associated with alterations in cognitive and emotional domains. Some studies suggest that LBP, neurocardiovascular instability, like the OH, and atherosclerosis resulting from long standing HBP, reduces cerebral blood flow, increasing the risk of cognitive impairment, morbidity and mortality. This study aims to evaluate whether patients with cognitive impairment and cardiovascular disease would show any differences in some anamnestic indicators and/or psychometric measures of cognitive performance and affective symptoms. We recruited 36 patients over 65 years of age admitted to both psycho- and cardio-geriatric ambulatories of our hospital during the last year. The population (mean age of 80.5 years, 72.2% females, 27.8% males) was divided in 2 groups, with OH (25%), and without OH (75%). The first group was subdivided in subgroups: patients with HBP, normal BP and LBP, respectively. Cognitive and depressive domains were assessed with the mini mental state examination (MMSE) and the Italian "scala di valutazione del benessere emotivo nell' anziano" (SVEBA). Information about the present status, comorbidities (cumulative illness rating scale=CIRS), functional ability (activities of daily living=ADL, instrumental ADL=IADL) and drugs were collected during clinical examination. BP was measured 4 times, at the beginning of examination, then with the patient in clinostatic and orthostatic position (1st and 3rd minute). Data were analyzed by MANCOVA, considering age and gender as covariates, MMSE, SVEBA, CIRS, ADL, IADL and drugs as dependent variables, and presence/absence of OH as factor. Covariates were not significant sources of variance, as well as overall factor. Due to the heuristic aim of the study, we considered of interest the results of subsequent ANOVAs showing significant differences in SVEBA and ADL with respect to the factor. These data give us the basis to develop a longitudinal study to confirm the detrimental effect of OH on a wide range of health domains.
