Brain donation procedures in the Sudden Death Brain Bank in Edinburgh

Brain banks typically receive donations through premortem consent procedures, often through disease-specific patient cohorts, such as dementia. While some control cases can be obtained through this route, access to age-matched control tissues, and some chronic neurologic conditions, particularly psychiatric disorders, can be challenging. The Edinburgh Sudden Death Brain Bank was established to try and increase access to control cases across all ages, and also access to psychiatric disorders through suicides. This chapter outlines the processes for establishing donations through medicolegal postmortems, which, although often with a prolonged postmortem interval, can provide high-quality well-characterized postmortem brain tissue to the neuroscience research community.
