Maastricht Aging Study

on the determinants of adult cognitive development


When people get older ...


memory and other cognitive functions seem to change. But is this true for everybody? It turns out that many young people are outperformed by middle-aged or older persons on cognitive performance tests. So what are the characteristics of people who age succesfully, what causes the age-related cognitive changes seen in usual aging, and what are the determinants of pathological aging, such as dementia?


These are the main questions of the Maastricht Aging Study (MAAS). This research program consists of several related studies about the biological, medical and psychosocial aspects of cognitive aging. The core project of MAAS was a longitudinal study in nearly 1,900 individuals aged between 24 and 81 years. Since 1992 our participants were tested at fixed intervals over a period of 12 years.  The analysis of the longitudinal data is still ongoing and is performed by researchers with a wide range of disciplinary backgrounds. Since 2019, a 25 year follow-up is being executed in all still available participants.


MAAS was carried out at Maastricht University and is based at the Maastricht school for Mental Health and Neuroscience (MHeNS), in association with the Caphri School for Public Health and Primary Care, and the Registration Network of Family Medicine (RNFM).


The river Maas runs through the heart of Maastricht. It is a symbol of the connection between the city and the MAAS study, but also the continuous and ongoing character of this longitudinal project.
