[Vascular risk factors and cognitive performance in patients 50 to 65 years-old].
BACKGROUND
Vascular risk factors (VRF) have been related to cognitive deficits and an increased risk of dementia. Cognitive impairment is considered to be one of the earliest manifestations of cerebrovascular disease. In Spain there is a high prevalence of VRF, but also one of the lowest incidences of cerebrovascular disease in Europe. This is the first study that investigates the relationship between VRF and cognition in a Spanish sample.


METHODS
A total of 90 people aged between 50-65 years with a low-to-moderate cardiovascular risk underwent a neuropsychological evaluation. None of them had a history of cardiovascular disease. The battery included tests assessing executive, attentional, mnesic, visuospatial and motor-speed/coordination functions. We used correlation and inter-groups comparison to relate VRF to multiple cognitive domains0120.


RESULTS
Higher stroke risk was significantly related to a lowered profile in visuo-constructive functions and motor-speed/coordination. Moreover, the group with moderate cardiovascular risk showed a lower performance in visuoconstructive functions compared to the low-risk group. After statistical adjustment for age, sex and years of scholarship VRF were only related to motor-speed/coordination.


CONCLUSIONS
In healthy, middle-aged adults, VRF are related with impairment in two cognitive domains. This effect is slight and tends to appear in people with moderate cardiovascular risk.
