Long-term consequences of repeated pentobarbital anaesthesia on choice reaction time performance in ageing rats (2001)

Blokland, A., Honig, W., Jolles, J.

Groot, J.C. De, Leeuw, F.E. De, Oudkerk, M., Hofman, A., Jolles, J., Breteler, M.M.

BACKGROUND: There is evidence for a vascular cause of late-life depression. Cerebral white matter lesions are thought to represent vascular abnormalities. White matter lesions have been related to...

Is nondipping in 24 h ambulatory blood pressure related to cognitive dysfunction? (1998)

Gaillard, C, Houx, P J, De Leeuw, P W, Jolles, J

OBJECTIVE: Associations between the outcome of 24 h ambulatory monitoring and cognitive performance were studied in order to evaluate the potential relevance of ambulant blood pressure status to...

The relation between morbidity and cognitive performance in a normal aging population (1998)

Houx, P J, Metsemakers, J F, Knottnerus, A, Jolles, J

BACKGROUND: Factors related to physical health have been implicated in both normal and pathological aging of cognitive abilities. To substantiate this notion, we studied existing morbidity, as...
