Aged Mental Health Research Unit


About the Aged Mental Health Research Unit

The Aged Mental Health Research Unit (AMHRU) studies depression and anxiety in residential aged care settings, the behavioural and psychological symptoms of dementia, ways to reduce over-prescribing of psychotropic medications, and brain stimulation therapies. We conduct clinical trials of psychological interventions for late life mental health, including individual psychotherapy for aged care residents and training programs for residential care staff to better manage residents with dementia and depression.

AMHRU is a partner of the Commonwealth Government's Dementia Collaborative Research Centre with responsibility and investigating non-pharmacological treatments of the behavioural and psychological symptoms of dementia.

We have several honours, masters, and doctoral level students currently conducting their research projects within our unit, and welcome all students.
