Adult Changes in Thought Study

Neuropathology Data

Neuropathology Data.png Data Description

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.

Study Forms

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.
