Abstract

Purpose: Post-mortem brain donation affords the opportunity to characterise disease by exploring global neuropathological changes. Such opportunities are essential to progress knowledge of CNS tumours such as Glioblastoma. A comprehensive understanding of the experience of consenting to brain donation is crucial to maximising consent rates while providing patient-centred care. This review aimed to synthesise the reported facilitators and barriers according to potential donors, next-of-kin (NOK) and clinician respondents.

Design: Database searches included Embase, Medline, PsycINFO, Psychology and Behavioural Science and Scopus. Search terms focused on motivations, attitudes and psychosocial experiences of brain donation. Exclusions included organ transplantation and brain death. All studies were assessed for quality and validity using tools from the Joanna Briggs Institute. To determine perceptions of benefit and harm, a method guided by the thematic analysis of Braun and Clarke was employed to reflexively assess and identify common themes and experiences.

Results: 40 studies (15 qualitative, 25 quantitative) were included involving participants with paediatric cancer, neurodegenerative and psychological diseases. Perceptions of benefit included benefit to future generations, aiding scientific research, avoidance of waste, improved treatments and the belief that donation will bring consolation or aid in the grieving process. Perceptions of harm included a perceived conflict with religious beliefs, disfigurement to the donor, emotional distress at the time of autopsy and discord or objections within the family.

Conclusion: Brain donation can afford a sense of purpose, meaning and empowerment for donors and their loved ones. Careful strategies are required to mitigate or reduce potential harms during the consent process.
