BPSD is quite common among people with dementia due to physical and external causes (such as genetics, pressure, changes in daily routine, over-stimulation or environmental changes). These causes will lead to unusual behaviour, which occurs in different stages of Alzheimer’s and other types of dementia.
Commonly seen behaviours include: unwilling to communicate with other people, changes in appetite, mental disorders, being prone to anxiety and becoming emotional, sometimes showing aggressive or repetitive actions, screaming, loitering, depression, suspiciousness, delusion and sleeping disorders.
Carers can try to understand the causes of such behaviour and offer suitable responses to reduce the likelihood of misunderstanding spiralling into confrontation. Carers can record the time, place and details of such events to help analyse the behaviour’s causes and responses.
