Key life stages of depression
Depression may change its form at different stages of the life cycle, as follows:

  • Post-menopausal - may become more severe in some women after menopause

  • Late-life - may occur for the first time in later life, particularly in association with certain types of physical illness, including heart disease and stroke3.



What changes take place in the brain during depression?
Nerve cells in the brain communicate with each other by means of chemical substances. During depression, the normal supply of these substances is reduced.

Antidepressants can help to restore these deficiencies by influencing certain chemical messengers in the brain and helping to re-establish normal brain functioning.


What treatments are available for depression?
There are several different treatments available for depression which are often used in combination. The use of pyschotherapy (counselling or 'talking therapy') and antidepressant drugs is well-supported by a large base of empirical evidence. There are also various self-help treatments, such as taking regular exercise, eating a balanced diet and getting sufficient rest2.


What treatment has recently become available for depression and how does it work?
Avanza (mirtazapine) has recently become available for the treatment of depression in Australia. With its broad action, it stimulates chemical messengers in the brain and helps to re-establish normal functioning. Its two way action means that it increases the levels of two chemical messengers - noradrenaline and serotonin - which are important in controlling mood.

The product should be taken with water at the same time everyday for at least six months, or as long as recommended by a doctor to prevent relapse. It is not addictive and long-term treatment should not have any negative effects on the patient4.
