A mental illness is a health problem that significantly affects how a person thinks, behaves and interacts with other people. It is diagnosed according to standardised criteria.
One in five Australians will suffer from a mental illness in any given year.
A mental health problem also affects how a person thinks, feels, and behaves, but to a lesser extent than a mental illness.
Mental illnesses are of different types and degrees of severity. Some of the major types are:
- bipolar mood disorder
- personality disorders
- eating disorders
These illnesses may also be referred to as a mental disorder, mental impairment or psychiatric disability.
