We talk about mental depression, but why not physical or physiological depression?
What is physiological depression?
We tend to think that depression is a mental phenomenon, not a physical or physiological one. Why not?
Why do we think that depression is a mental phenomenon?
The general idea:
Depression is caused by a neuro-chemical-hormonal imbalance or aberration in the head, skull, and brain.
The theory is about serotonin, dopamine problems in the brain is the cause of depression. Thus, if we simply fix the serotonin or dopamine signaling pathways to be “normal”, then the feelings of depression, ennui, etc will go away.
What if the brain and mind were a physical, bodily, and physiological phenomenon?
Physiological sickness and illness leads to mental depression.
