The types of data that are collected and can be used include: Electronic Health Records, Study Visits, Genetics and Biomarkers, Neuropathology, Physical Measures, Neuroimaging and Life Course Exposures. ACT data can be accessed through the Data Query Tool available on the ACT website and in consultation with the ACT steering committee.
