Some participants of the Adult Changes in Thought (ACT) Study consent to brain autopsy upon death, generously donating their brain for neuropathological assessment by the ACT Neuropathology Core. After autopsy, complete neuropathological assessments are performed, and data elements derived from those assessments of ACT participant brains are collected and stored. The ACT neuropathology dataset contains measures from approximately 850 ACT participants who died as of the current data freeze date March 5, 2020.
Not applicable. Because these data elements are derived directly from neuropathological assessments performed at autopsy, no forms are used to collect these data from participants.
The following publications provide additional detail on the neuropathology data elements. These may be helpful supporting citations when publishing analyses using these data.
