Czech Brain Aging Study (CBAS)
CBAS is a prospective longitudinal memory clinic-based multicentre study of over 1,200 non-demented adults aged 55 and above in the Czech Republic. Participants are mostly volunteers who attended as a self-referral with memory complaints expressed by themselves or the family, or who were referred by general practitioners, local specialists or the Czech Alzheimer Society. A further cohort was also formed, CBA Plus, which contains baseline data for over 400 participants who did not meet the CBAS inclusion criteria due to mild dementia of various neurodegenerative origins, depression and history of stroke, but gave informed consent to take part in the study.
