    • Few data exist on the effects of specific Alzheimer's disease (AD)-related mutations on cognitive function. We present neuropsychological test results in eight members of a large kindred with variant Alzheimer's disease (VarAD) due to a deletion of the presenilin 1 (PS-1) gene, encompassing exon 9. The disease was neuropathologically characterized by the presence of large, unusual, "cotton wool" plaques (CWP). Four surviving patients were prospectively tested, and retrospective neuropsychological data were collected from additional four deceased patients. The neuropsychological evaluation was based on tests of verbal and visual memory, abstract thinking, and visuoconstructive and spatial functions. In addition, psychiatric symptoms were evaluated. In four patients, brain glucose metabolism was examined by positron emission tomography (PET). PET showed temporoparietal hypometabolism typical of AD. In addition, variable patterns of hypometabolism (hemispherical asymmetry and occipital accentuation) were related to individual deficits of cognitive performance. However, all these early-onset patients (age range 43-63 years) with a deletion mutation of PS-1 gene showed prominent memory impairment and deficits in visuoconstructive and intellectual functions.

    • 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.
