Definition data were analysed deductively using the Diagnostic and Statistics Manual of Mental Disorders 5th Edition Text Revision (DSM-5-TR) Personality Change Due to Another Medical Condition diagnostic criteria, and inductively to uncover new ideas related to descriptions of brain tumour\u2013related personality and behaviour changes perceived by carers and healthcare professionals. Inductive thematic analysis was conducted to develop themes exploring the impact of patient personality and behaviour changes on carers.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Two themes were identified from participants\u2019 description of personality and behaviour changes associated with brain tumours: (i) variable presentation and multifactorial aetiology and (ii) manageable versus challenging changes.

Brain tumour\u2013related aggression was identified as a significant concern by both healthcare professionals and carers, lacking clinical guidelines internationally for managing violence and aggression in this population.
