Causes of depression

There isn’t a simple explanation for what causes depression, although you may have heard that it’s due to a chemical imbalance in the brain.

The fact is, despite decades of research, scientists have been unable to produce any hard evidence to support the hypothesis that depression is a result of a serotonin deficiency or some other neurotransmitter imbalance or dysfunction.

Regardless of the lack of scientific support for the idea, the public, the media, and even many healthcare professionals, are still under the misapprehension that it is proven to be caused by a biochemical abnormality and that this is corrected by selective serotonin reuptake inhibitors (SSRIs) or other types of antidepressant drugs.  In recent years, a considerable number of researchers and clinicians working in the fields of psychiatry, psychology and psychotherapy have published books that expose the myths surrounding the serotonin hypothesis and raise awareness of the dangers of antidepressants.
