Info Centre » What is Depression?
Depression is a mood disorder characterised mainly by prolonged feelings of sadness. It is caused by a chemical imbalance in the brain which restricts brain cells ability to communicate with each other, so the part of your brain which releases serotonin (the chemical in your brain that allows you to feel happiness) may not produce enough, or the serotonin may not properly get delivered to the appropriate part of the brain.

Bi-Polar Disorder (also known as Manic Depression) is a form of depression characterised by moods cycling through extreme highs (also known as manic periods) followed by periods of depression.
