Types of mental illness

1-minute read

There are nearly 300 mental disorders listed in the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders). This is a handbook used by health professionals to help identify and diagnose mental illness.

Some of the main groups of mental disorders are:

The diagnosis of mental illness can be controversial. There have been many debates in the medical community about what is and isn’t a mental illness. The definition can be influenced by our society and culture, but most mental illnesses occur across all countries and cultures. This suggests that they are not just constructed by social norms and expectations, but have a biological and psychological basis too.

Not sure what to do next?

If you or someone you know are finding it difficult to manage mental health issues, try healthdirect’s Symptom Checker and get advice on when to seek professional help.

The Symptom Checker guides you to the next appropriate healthcare steps, whether it’s self-care, talking to a health professional, going to a hospital or calling triple zero (000).

Complementary Therapies and mental illness.

What are complementary therapies? These are ways of helping yourself stay healthy which complement medical treatment. While these can be useful, care needs to be taken, especially when you have a mental illness. Some people use them instead of medical treatment or without consulting their doctor – this can be dangerous as substances used in ‘natural’ therapy are not required to undergo the same rigorous tests for safety as prescribed medications. The term ‘natural’ is also misleading, as most prescribed medications are actually derived from natural substances too.
