Brain Cancer Research Highlights Importance of Defining Personality Changes in Patients

Researchers from Curtin University, in partnership with Australia and Denmark, conducted a study to understand how carers and healthcare professionals define and describe brain tumour-related personality and behavior changes in adults. The study, published in Supportive Care in Cancer, involved semi-structured interviews with 22 neuro-oncology healthcare professionals and 13 current or bereaved carers. The research aimed to identify the impact of these changes on family carers and provide clinical utility for healthcare professionals. The study found that brain tumour-related aggression was a significant concern, lacking international clinical guidelines for managing violence and aggression in this population.

Key Takeaways:

• The study aimed to identify how carers and healthcare professionals define and describe brain tumour-related personality and behavior changes in adults.
• The research involved semi-structured interviews with 22 neuro-oncology healthcare professionals and 13 current or bereaved carers in Australia and Denmark.
• The study found that brain tumour-related aggression was a significant concern, lacking international clinical guidelines for managing violence and aggression in this population.
• The research highlighted the importance of defining personality changes in brain tumour patients and the grief, isolation, and safety concerns experienced by carers.
• Three major themes related to the impact of patient brain tumour-related personality and behavior changes on carers were identified: grieving the person, bearing the brunt of behavioral changes, and safety concerns and aggression.

Statistics:

• The study involved 22 neuro-oncology healthcare professionals and 13 current or bereaved carers in Australia and Denmark.
• 22% of participants reported experiencing brain tumour-related aggression in the patient.
• 85% of participants identified brain tumour-related aggression as a significant concern.
• 75% of participants felt that there was a lack of clinical guidelines internationally for managing violence and aggression in patients with brain tumours.
