The aim of our study was to evaluate the relationship between health-related factors, brain imaging findings and cognitive functioning. We examined 113 neurologically healthy subjects from 55 to 85 years of age. Health-related variables included a clinical health evaluation, cardiovascular diseases, and other systemic diseases. The presence of white matter changes and cerebral and peripheral atrophy were obtained with magnetic resonance imaging. Neuropsychological tests measuring verbal memory, visual memory, intellectual and language functions, visuoconstructional functions, flexibility, and speed and attention were administered. Results showed that overall health status was not related to cognition. Subjects, who had both arterial hypertension and white matter changes had difficulties in flexibility. Cardiac failure and white matter changes were related to impairment in visuoconstructional functions, flexibility and attention. Significant speed and attention deficits were observed in subjects with cardiac failure and central atrophy. In conclusion, this study verifies the relationship between hypertension, white matter changes and cognitive functions. We found also specific patterns in relation with cardiac failure, brain imaging findings and cognitive functioning, the most vulnerable domains were visuoconstructional functions, flexibility and attention.
