How to help someone with depression without drugs?

Compelling research evidence exists that there is often a neurophysiological basis for depression, particularly in people with a family history of depression.

The left frontal area of the brain is associated with positive emotions and approach motivation, which is a desire to be involved with other people. The right frontal area of the brain is more associated with depression and fear, accompanied by motivation to withdraw from and avoid other people. When there is more slow brainwave activity in the left frontal area, this part of the brain is more inactive and the right frontal area is more dominant. Such a person is predisposed to become depressed more easily, to withdraw from other people, and to be anxious.

According to ISNR website, it is interesting that research has found that antidepressants do not correct the type of brainwave pattern that we see above on the left. Thus, medication treatment for depression appears to still leave intact the biological predisposition for becoming more easily depressed when unpleasant life circumstances come along.

I am working in a proactive healthcare centre (non-drug approach) at Setapak as a psychologist. I am supervised by a medical doctor and a PHD level psychologist who specializing in biofeedback for more than 20 years. I am using clinical hypnotherapy and biofeedback methods to help my clients.
Our unique approach for depression appear very promising not only in bringing relief from depression, but in modifying the underlying biological predisposition for becoming depressed. Biofeedback focuses on retraining the brain, for example, reversing the frontal brainwave asymmetry, with the goal of producing an enduring change that does not require people to remain on medication indefinitely. Training often requires about 20 to 22 sessions.
