It's all about the receptors, really. There are 7 families of serotonin receptors that perform different functions within the brain, and according to Wikipedia 14 different subtypes have been discovered. The article assumes that a blanket level of serotonin would be sufficient to "perk" up the brain, wherein it is much more complicated. Serotonin serves ...

In a meta-anylysis, Bohlmeijer (2007) found that: In the last twenty years reminiscence has been applied in a large number of settings and with a large number of target groups. Examples of applications are: community-residents with a major depression, elderly with moderate depressive symptoms, nursing home residents, elderly with dementia, ...

There certainly isn't a single cause of depression. Wikipedia does not list inflammation, so that seems to be sufficient disproof of universal acceptance, and at least one candidate for representative of mainstream opinions. Berk and colleagues (2013) make a pretty convincing case though, so it may only be a matter of time, exposure to the evidence, and ...

However, if the question was "Is Major Depressive Disorder or Dysthimia the result of deficits in serotonergic signaling?" the answer becomes much less black-and-white.

I would like to point out the definitions of James Park of the University of Minnesota; please have a look at the table at the bottom of this page. So then, people with perfectly fine lives might well end up with a "clinical ...

While it is indeed one of the theories, it is by no means not the mainstream one. Nowadays, it seems the neurogenic theory of depression is gaining a lot of support, if one looks at recent publications. Briefly, the theory claims that impaired neurogenesis prevents replenishment of parahippocampal granule cells that normally inhibit the amygdala – a ...

There are different theories about the causes of depression. Three of them assume a cause that could be affected by aerobic exercise. Neurochemical theory of depression: It seems that depression might be caused by low serotonin and/or noradrenalin levels. Physical activity releases both neurotransmitters, thus alleviating depressive symptoms. Cognitive ...

This may be more of a non-answer than an answer, but here it goes. When you're talking about the effect of something like pain, it's valuable to first understand some of the complexity. While it's easy to put things in boxes in practice, (physical pain, emotional pain, etc.) it's very difficult to put those things in boxes when you're talking about a ...
