1 The particular psychological vulnerabilities of later life
Ageing brings natural changes in the brain, alongside an accumulation of vulnerabilities: a gradual loss of physical independence, successive bereavements, social isolation, multiple illnesses and the use of multiple medications. Old age psychiatry addresses the mental health of people over sixty-five, whether they are living with psychiatric conditions that began in youth and have continued into old age, or with disorders that emerged later through neurodegenerative processes or painful life events.
2 What an old age psychiatric assessment involves
The consultation takes a comprehensive, compassionate approach. The physician allows time to assess higher cognitive functions, including episodic memory, orientation in time and space, language and learned motor skills, using validated tests such as the MMSE or MoCA. All prescribed medications are carefully reviewed for possible treatment-induced harm or toxic interactions, since older people are particularly sensitive to the sedation and confusion caused by certain psychotropic drugs. Family carers occupy a central place in the interview, and their physical and psychological exhaustion is routinely assessed and addressed.
3 Reasons for consultation and benefits for patients and families
Common reasons for consultation include depression in older adults, which is often atypical, presenting as repeated physical complaints, withdrawal or loss of appetite rather than expressed sadness; behavioural disturbances associated with Alzheimer's disease or vascular dementia, including aggression, night-time wandering, hallucinations and persecutory ideas; and acute confusional states. The old age psychiatrist helps restore calm to everyday life, adjust care and enable the person to remain at home under the best possible conditions for preserving dignity.
4 Supporting carers and preserving the living environment
A crucial part of the psychiatrist's role is preventing exhaustion among spouses and adult children who provide care. By recommending day services or respite support, the physician helps prevent anxiety crises within the family and delays admission to a specialist institution wherever possible, enabling the person to remain at home in a calm, respectful environment.
