1. Major depressive disorder (MDD)
This is the most common type of depression people experience in Australia. It can be mild, moderate or severe depending on the intensity of the symptoms and how much they impact day-to-day life. There are several symptoms including depressed mood and loss of interest or pleasure in normal activities.
2. Major depressive disorder with melancholia
This is a severe form of depression defined by a complete loss of pleasure in almost everything, feelings of despair, excessive guilt and a slowing down of movement or restlessness.
3. Psychotic depression
Psychotic depression is when a person experiences hallucinations, paranoia and delusions in addition to major depressive disorder. Although it is less common than other forms of depression, it is severe and often requires a combination of treatments.
4. Perinatal and postnatal depression
There is no doubt that becoming a parent can be a physically and emotionally challenging time and a big adjustment. Approximately 15-20% of Australian women experience depression during pregnancy or in the year after giving birth. It is normal and common for women to feel down, tired or irritable in the days and weeks after having a baby and require support from the community during this time. It is important to speak to a professional to understand whether a persistent low mood may require treatment for depression. It is important to note that fathers can experience depression in the postnatal period, too, and should seek support. Seeking help early can improve the experience of parenting and improve relationships between family members.
5. Persistent depressive disorder
When a person has experienced depressive symptoms for more than 2 years, this may be diagnosed as persistent depressive disorder. Because the depression symptoms have been present for a long time, people may not realise they are experiencing depression and so may not seek help until encouraged to do so by a friend or family member.
