This is about how we think, feel and behave. One in four people in the UK have a mental health problem at some point in their lives, which affects their daily life, relationships or physical health. Mental health disorders take many different forms and affect people in different ways. Schizophrenia, depression and personality disorders are all examples of mental health problems.
Diseases such as Alzheimer’s and dementia generally develop in old age, whereas eating disorders are more common in young people.
