What is depression?
Depression is a persistent state of reduced motivation, low mood, and cognitive heaviness — a brain and body shifted toward withdrawal rather than engagement. It is common, it is treatable, and it is not a sign of weakness.
Around one in seven Australians will experience depression in their lifetime, and on any given day around 4–5% of adults are navigating an episode [1]. The presentations we see most include:
- Major depressive episodes — sustained low mood, loss of interest, sleep and appetite changes, fatigue, difficulty concentrating.
- Persistent depressive disorder (dysthymia) — a longer, lower-grade version that quietly shapes years of life.
- Post-natal depression — appearing in the months after childbirth, with its own clinical considerations.
- Burnout-related depression — covered overlapping with our stress & burnout page.
- Treatment-resistant depression — where standard first-line care has not given the relief expected.
Underneath the experience is often a brain and body that have settled into a low-arousal, low-engagement pattern — and the work, in any clinical setting, is to help that pattern shift.
