   en.wikipedia.org/wiki/Biology_of_depression

   The biology of depression is the attempt to identify a biochemical origin of depression, as opposed to theories that emphasize psychological or situational causes. Scientific studies have found that different brain areas show altered activity in humans with major depressive disorder (MDD) . [ 1 ]

3. Serotonin–norepinephrine–dopamine reuptake inhibitor

   en.wikipedia.org/wiki/Serotonin–norepinephrine...

   The original monoamine hypothesis postulates that depression is caused by a deficiency or imbalances in the monoamine neurotransmitters (5-HT, NE, and DA). This has been the central topic of depression research for approximately the last 50 years; [ 12 ] [ 192 ] it has since evolved into the notion that depression arises through alterations in ...

4. Neurogenesis hypothesis of depression - Wikipedia

   While depression is a complex condition with many factors involved, it is commonly attributed to an imbalance of several key monoamine neurotransmitters, including serotonin, dopamine and norepinephrine. This monoamine hypothesis of depression is popular because of the simplicity of the explanation. [4]

   Alcohol-related brain damage [1] [2] alters both the structure and function of the brain as a result of the direct neurotoxic effects of alcohol intoxication or acute alcohol withdrawal. Increased alcohol intake is associated with damage to brain regions including the frontal lobe , [ 3 ] limbic system , and cerebellum , [ 4 ] with widespread ...

7. Neurotrophic hypothesis of depression - Wikipedia

   en.wikipedia.org/wiki/Neurotrophic_hypothesis_of...

   The neurotrophic hypothesis of depression [1] proposes that major depressive disorder (MDD) is caused, at least partly, by impaired neurotrophic support.Neurotrophic factors (also known as neurotrophins) are a family of closely related proteins which regulate the survival, development, and function of neurons in both the central and peripheral nervous systems.
