Geriatric Psychiatry

Overview

Geriatric Psychiatry is a specialised service under the Centre of Geriatric Medicine that focuses on the mental health, emotional wellbeing, memory, behaviour, sleep, and psychological needs of older adults. It is especially helpful for seniors who have depression, anxiety, dementia-related behavioural symptoms, delirium, sleep problems, loneliness, grief, or complex medical conditions affecting mental health.

Mental health concerns in older adults are common, but they are not a normal part of ageing. Early diagnosis and compassionate treatment can improve mood, thinking, independence, safety, and quality of life.

What Is Geriatric Psychiatry?

Geriatric Psychiatry, also called old age psychiatry, deals with the prevention, diagnosis, treatment, and long-term care of mental health conditions in older adults. It considers physical illness, medicines, memory, mobility, family support, social isolation, and daily functioning together.

Common areas of care include:

• Depression and anxiety in older adults

• Dementia-related mood and behaviour changes

• Delirium and sudden confusion

• Sleep disorders

• Grief, loneliness, and adjustment difficulties

• Late-life psychosis or hallucinations

• Bipolar disorder or long-standing psychiatric illness in older age

• Substance or alcohol-related concerns

• Medication-related confusion or behavioural changes

• Caregiver stress and family counselling

• Capacity, safety, and long-term care planning

Causes and Risk Factors

Mental health problems in older adults may develop due to medical, psychological, neurological, social, or medicine-related factors.

Common risk factors include:

• Chronic illness or long-term pain

• Dementia or cognitive decline

• Stroke, Parkinson’s disease, or other neurological conditions

• Bereavement or major life changes

• Social isolation or loneliness

• Reduced mobility or loss of independence

• Sleep problems

• Multiple medicines or medicine side effects

• Alcohol or substance use

• History of depression, anxiety, bipolar disorder, or psychosis

• Elder abuse, neglect, or caregiver stress

• Recent hospitalisation or surgery

Older adults taking several medicines need careful review, as some medicines can worsen confusion, memory, sleep, mood, or balance.

Symptoms

Symptoms may appear as emotional changes, memory problems, behaviour changes, sleep disturbance, or reduced ability to manage daily life.

Common symptoms include:

• Persistent sadness, hopelessness, or crying spells

• Excessive worry, fear, or restlessness

• Loss of interest in usual activities

• Sleep problems or daytime sleepiness

• Poor appetite or weight loss

• Memory loss or confusion

• Irritability, agitation, or aggression

• Suspiciousness or hallucinations

• Withdrawal from family or social activities

• Poor self-care or neglect of medicines

• Repeated falls linked to confusion or medicines

• Talking about death, self-harm, or feeling like a burden

• Sudden behaviour change after infection, surgery, or hospitalisation

Urgent help is needed for suicidal thoughts, self-harm, severe agitation, hallucinations with unsafe behaviour, sudden confusion, seizures, inability to care for basic needs, or risk of harm to self or others.

Diagnosis

Diagnosis begins with a detailed geriatric psychiatric assessment. The doctor evaluates mood, memory, behaviour, sleep, medicines, physical illness, family concerns, and daily functioning.

Common assessments include:

• Psychiatric history and mental status examination

• Memory and cognitive screening

• Depression and anxiety screening

• Delirium assessment when confusion is sudden

• Review of all medicines and supplements

• Physical health evaluation

• Blood tests for thyroid, vitamin deficiency, infection, sugar, kidney, liver, and electrolyte problems

• Brain imaging in selected memory, stroke, or neurological concerns

• Sleep, pain, nutrition, and mobility assessment

• Family or caregiver input when appropriate

• Safety and suicide-risk assessment

A careful diagnosis helps distinguish depression, dementia, delirium, medicine side effects, and medical causes of behavioural change.

Treatment Options

Treatment is personalised according to the diagnosis, age, medical conditions, medicines, safety needs, and family support.

Geriatric Psychiatry care may include:

• Counselling and psychoeducation

• Psychotherapy adapted for older adults

• Medicines for depression, anxiety, sleep, psychosis, or mood symptoms when needed

• Careful medicine selection to reduce side effects and interactions

• Memory care planning for dementia

• Non-medicine approaches for agitation, sleep, and behaviour changes

• Treatment of underlying medical causes such as infection, pain, dehydration, or vitamin deficiency

• Sleep routine and daily activity planning

• Social engagement and loneliness reduction strategies

• Family counselling and caregiver support

• Safety planning for falls, wandering, self-harm, or medication errors

• Hospital care when symptoms are severe or safety is at risk

Medicines should be started carefully and reviewed regularly because older adults may be more sensitive to side effects.

Prevention and Outlook

Mental wellbeing in older adults can be supported through regular health check-ups, social connection, physical activity, good sleep, balanced nutrition, pain control, hearing and vision care, medicine review, and early support after bereavement, illness, or hospitalisation.

The outlook depends on the condition and overall health. Depression, anxiety, sleep problems, and some causes of confusion can improve significantly with treatment. Dementia-related symptoms may need long-term care, but timely support can improve safety, comfort, family coping, and quality of life.

Frequently Asked Questions

1. When should an older adult see a geriatric psychiatrist?
   They should be evaluated for persistent sadness, anxiety, memory problems, sudden confusion, hallucinations, sleep problems, agitation, social withdrawal, unsafe behaviour, or caregiver concern.

2. Is depression normal in old age?
   No. Depression is common in older adults but is not a normal part of ageing. It can be treated with counselling, medicines, social support, and medical care.

3. What is the difference between dementia and delirium?
   Dementia usually develops gradually over time. Delirium is sudden confusion, often due to infection, dehydration, medicines, surgery, or acute illness, and needs urgent medical evaluation.

4. Can medicines affect memory or behaviour?
   Yes. Some medicines and combinations can cause confusion, sleepiness, falls, hallucinations, or memory problems in older adults.

5. Can dementia-related behaviour be managed?
   Yes. Behaviour changes can often be reduced by identifying triggers, improving routine, treating pain or infection, supporting caregivers, and using medicines only when clearly needed.

6. How can families support older adults with mental health concerns?
   Families can help by encouraging medical care, monitoring medicines, reducing isolation, maintaining routines, ensuring safety, and seeking caregiver support when needed.
