Neuropathology is the study of the diseases of the nervous system. The purpose of our neuropathology screening is to confirm, correct, or expand upon the clinical diagnosis. When the medical records and the Confidential Brain Donor Questionnaire have been collected at the HBTRC, a final neuropathology report is generated by the HBTRC staff neuropathologist for postmortem diagnostic purposes. A detailed review of the medical records, questionnaire and neuropathology report will be done to confirm the brain diagnosis and other relevant conditions. This is done so that the HBTRC can reliably give researchers the correct tissue samples needed for their studies. The legal next of kin/legal representative may receive a copy of the final neuropathology report at no cost and may request that a copy of this report be sent to the donor's physician.
