People who kill themselves usually believe that they are in an unbearable situation from which they cannot escape and that things won't ever get better. The problem with research into the reasons for suicide is that those that successfuly killed themselves can no longer explain their motives, and those that survived might – consciously or unconsciously – ...

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 ...

The truth is that very few people who haven't seriously contemplated suicide, or who haven't dealt extensively with many people who have, really understand it. They will, like you, not figure it out, thinking there are so many other options available to them. It is even more puzzling when wealthy people, who have so many more options than most, do so, while ...

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 ...

It may interest you to know that depression and anxiety relate to emotional stability (essentially the opposite of neuroticism), a personality trait which tends to decrease over the lifespan, especially in young adulthood (Roberts & Mroczek, 2008). Here's a figure depicting this trend (bottom left): This article points out that most of the personality ...

"Their lives are perfectly fine" is a hard to test thing. Hard to compare. How people feel and respond is deeply contextual. However there are several potential reasons: They may be 'wired' to feel stress or respond emotionally (i.e. Due to the way their brain has developed). A feeling of not being in control (This is often hard to perceive from outside ...

The ICD and DSM definitions can be a bit opaque, but there are several criteria that are usually considered necessary for diagnosis. Different practitioners may diagnose more conservatively or more pervasively, but those differences are based on their professional experience, and they are all meant to interpret from similar guidelines. Because there are ...

I would also like to point out that there is a clear difference between a psychological depression and an existential one. 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 ...

I suppose at face value, the answer to the question "Is serotonin linked to depression?" would 'yes'. 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. First, to piggyback on Chuck's response, it is very important to consider 5-HT ...

I'm not any kind of professional in this field, but I can say just a few things about this from experience in my family. I thought depressive feelings and being diagnosed with depression are one and the same. But health of a family member gave me insight into feelings that can't be changed just because your belief changes. Depressed person, with altered ...

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 ...

Whew, OK. I am going to take a crack at this. The question asks about depression diagnoses, so I will interpret and focus on that accordingly. I think we can all agree that making any clear distinction between endogenous and exogenous causes of depression is difficult, since 1) liken to the Nature vs. Nurture question, people generally agree that Major ...

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 ...

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 ...

A common definition of "conflict" is readily retrievable and applicable in the context of clinical evaluation – i.e., conflict has no particularly unusual primary meaning in clinical psychology. "Interpersonal" also operates as an ordinary adjective with the usual meaning. Thus interpersonal conflict is conflict between persons, as might be distinguished ...

Siblings as children do this alot. Most people grow out of it. I would think these symptoms reflect a kind of hypochondriasis which is a factitious disorder with an underlying dependant (or inverse dependence) disorder. It could also be an incorrect empathic response due to a narcissistic disorder. The aggressive features as a response to others doubts ...

The proverb you mention is overly general to the point of being largely false (or at least unfalsifiable, to give some credit to the defensibility of philosophical solipsism otherwise). @JunJun and @felino's answers also generalize too much, but this is partly a consequence of a lack of specificity in the OP. Depression in general is widely misunderstood and ...

Look up Jeffery Schwartz. He has done decades worth of scientific studies with hundreds of OCD patients. In his book "You Are Not Your Brain" (worth a read) he mentions this bad brain wiring or cognitive deficits are the culprit behind the "Deceptive Brain Messages (OCD). His studies show that self directed neuro-plasticity make the most corrections in ...
