Mental Health in Older People

Last Modified 27/03/2023 14:29:17 Share this page


Social isolation and loneliness are recognised risk factors for poor mental health and are experienced by over one million older people in the UK1,2. Based on current population projections, the number of people aged 50 and over in England who often feel lonely will reach 2 million by 2025/263. Strengthening positive relationships and promoting opportunities for participation in meaningful activities in later life will help to promote mental health and wellbeing for all of us. Factors that contribute to loneliness, social isolation and increased risk of mental health problems in older adults include3,4:

    • Living alone
    • Poor physical health
    • Being widowed or experiencing other bereavement
    • Having family circumstances that prevent them doing things they want to (mobility, caring roles, digital exclusion etc.)
    • Having financial concerns / poverty
    • Not having someone to open up to when they need to talk
    • Discrimination

Amongst the over 65s the two most common mental health problems are depression and dementia. Loneliness has been associated with an increased risk of dementia; and loneliness, social isolation and living alone have also been associated with premature death2.

The COVID-19 pandemic has exacerbated social isolation, loneliness and mental health concerns among older people. A 2021 Age UK study found that:

    • Pre-existing mental health conditions had worsened
    • Anxiety levels, low mood, low confidence, and depression had increased
    • More people had become withdrawn and isolated
    • Coping strategies have been limited
    • Some older people's self-care had deteriorated
    • Some older people had adopted unhealthy coping strategies (excess eating, smoking, alcohol use)
    • Some older people's cognitive ability has declined as a result of reduced social contact
    • Those with dementia had been severely impacted, with rapid cognitive decline

Facts and Figure


In England there are an estimated 676,000 people in England with dementia, and around 540,000 carers6. 95% of people affected by dementia in the UK are over 65 and prevalence increases significantly with age7.

The needs of people with dementia and their carers already require high levels of health and social care input and this requirement will increase to meet the projected needs of this rapidly growing group. Family carers of people with dementia are often older and frail themselves with high levels of depression and physical illness and a diminished quality of life. Hence, dementia is seen as an NHS priority area, and in 2009 a National Dementia Strategy was launched. This was followed by the coalition government's 'Prime Minister's Challenge on Dementia' and in 2015 a further 'Challenge on Dementia 2020' aimed at improving dementia care, support and research by 2020.

Dementia is the single most frequent cause of admission to care homes, and of the need for community care services for older people. The demographics of an ageing population indicate the number of people with dementia in Blackpool is predicted to rise to around 2,660 by 2040 (Figure 1).

In the UK depression affects around 1 in 5 older people living in the community and 2 in 5 living in care homes. However, fewer than one in six older people with depression ever discuss this with their GP8. As the population ages within Blackpool, the number of people affected by depression is expected to increase (Figure 2).
