Healthy Brain Study (HBS)
The HBS is an interdisciplinary study based on multidimensional, dynamic assessments in both the laboratory and the real world. Between 2019 and 2024, the study tested over 900 individuals in their thirties, who have collectively spent over 500,000 hours on tests and tasks. The sample consists of 30 - 39-year-olds living in Nijmegen (Netherlands) and its surroundings. A reasonable level of reading, speaking, and understanding of Dutch (B1 level) was required, implying that the HBS participants do not fully represent the Nijmegen population at large because the illiterate, people with low literacy, or non-Dutch speaking individuals are excluded. As of December 2021, participants performed 755 total lab visits: 380 participants carried out the first assessment, 237 participants the second assessment, and 138 participants the third assessment, completing the entire study protocol.
