Both schizofrenia and depression are linked to a genetic predisposition and life events.

Short answer: Bipolar disorder is probably not composed of two comorbid illnesses, but it may be on a continuum that includes some depressive disorders. This is a good question, though it does convey some confusion associated with this diagnosis that should be cleared up. Bipolar symptoms: The first confusion I think is the idea that "depression", ...

Human depression has been modeled in a variety of animal models, including cats (Wilner, 1984). Cats show comparable signs of distress when subject to maternal separation, including separation phenomena of protest, followed by despair.

Overall, based on my limited research it appears there is no evidence that people who are more logical are more likely to experience depression. There is a theory that people who see the world more accurately (of which rationality would be a component) are more likely to become depressed. It is called depressive realism {1}. However, the theory doesn't seem ...

Yes, they can coexist. No, they aren't opposites. How could they be? Both ADHD and OCD affect a variety of different brain regions, and its effects are not consistent in every person. Maybe if OCD and all its symptoms were always caused by an excess of dopamine in one specific pathway in the reward system, whereas ADHD and all its symptoms was always caused ...

This is a big question, but here are a few thoughts. While we could argue about the details, concepts around set points and the hedonic treadmill have reasonable empirical support. The general finding is that life satisfaction ratings are fairly stable from year to year (Lucas & Donnellan, 2007) which suggests that there are relatively stable individual ...

There is a lot of research on depression in animals. Wikipedia has a good summary of the comparison of depression between animals and humans: It is difficult to develop an animal model that perfectly reproduces the symptoms of depression in patients.

I would say it is impossible. Being unhappy is a necessary experience to make the feeling of happiness arise. Maybe there is some joyful state that can persist over time without unhappiness but I doubt it. As I see it, unhappiness at times comes with the deal of living.

Depression is characterized by emotion dysregulation (e.g., Joormann & Vanderlind, 2014). This means that depressed patients have difficulties decreasing (downregulating) their negative affect and increasing (upregulating) their positive affect. This may be a consequence of cognitive distortions and deficits (Joormann & Vanderlind, 2014) as well as ...

There's no theoretical reason to believe that depression is characterized by an increase in "double implications." If anything, the double implication you've posed (depression ⟺ no friends) is a pretty accurate understanding of the reciprocal relationship between the causes and consequences of depression (e.g., Stice, Ragan, & Patrick, 2004; Teasdale, ...

These small effects are comparable with what would be expected ...

A narrower use of the term refers to a disorder of brain function that affects emotion, learning ability, self-control and memory and that unfolds as the individual grows. You are correct ...

Daniel Gilbert actually coined a term called immune neglect (Gilbert et al., 1998), which describes a common bias in affective forecasting. The idea is that when we try to predict how we'll feel following a negative situation, we fail to take into account (i.e., we neglect) that our psychological "immune system" will kick in and return us to some neutral ...

The best way to set up a Mechanical Turk longitudinal study is with TurkPrime.com. You can follow-up with users and invite them to take a new survey. As long as they are properly incentivized they will come. I recommend that you inform them at the start that you are running a 10 part study and that those who perform well on each of the 4 minute studies will ...

For "permanent" loss of experience of happiness or pleasure, check out the term Anhedonia From my own understanding, a brain can shift between different states of mind. Depression is just one such state. I have a more detailed answer about states of mind here, but the important point is that states of mind color perception of past, present and future. Your ...
