Mental well-being means the positive ability to enjoy life and cope with its difficulties and challenges.
Ageing does not have to mean a decline in mental health. There are many ways in which you can maintain good mental health, even if physical and health issues are making life more of a challenge. Just as we care for our bodies, we need to look after and exercise our minds.
Being a bit forgetful can often come with age, and does not mean you have dementia.
We all feel a little sad or down from time to time but feeling down is not the same as being depressed or having depression. Take steps to help prevent depression. Depression can affect older people. Many older people experience psychological or emotional distress associated with factors linked to old age, including loss of independence, loneliness and losses of many kinds, including bereavements. If you feel unable to cope it is important to tell your GP, don't suffer in silence and get help.
