Dementia can affect more than memory. Changes in personality, emotions, and behaviour may sometimes be among the noticeable symptoms. Common behaviour changes in dementia may include: • Increased irritability or anger • Becoming unusually suspicious or fearful • Loss of interest in previously enjoyed activities • Social withdrawal • Reduced motivation or initiative • Impulsive or socially inappropriate behaviour • Repetitive actions or questions • Increased anxiety or emotional sensitivity • Reduced awareness of other people’s feelings These changes occur because dementia can affect brain regions involved in judgment, emotional regulation, and social behaviour. In frontotemporal dementia, personality and behavioural changes may appear even before significant memory problems. A sudden change in behaviour should not automatically be attributed to dementia. Pain, infection, medication effects, sleep problems, or delirium can also cause behavioural changes, particularly in older adults. Understanding personality changes in dementia can help families recognise that these behaviours may be symptoms of changes occurring in the brain rather than deliberate actions.
