The only study I'm aware of is the following: Cannabis increased verbal fluency in low creatives to the same level as that of high creatives. Cannabis increased state psychosis-like symptoms in both groups and the high creativity group were significantly higher in trait schizotypy, but this does not appear to be linked to the verbal fluency change. Acute ...

Yes it is possible, but it is difficult. The way it would be done currently is to insert a needle into the base of your spinal cord to measure the concentration of a metabolite of serotonin, 5-HIAA, in the fluid surrounding your brain. It is also possible to measure levels of this metabolite in saliva, urine, or in the bloodstream, but these measures would ...

Low self-esteem can be the result of severeal things, implying depression and other mental disorders, past experiences (harassement for example). We can "fix" low self-esteem through non-drug therapy, but sometimes we can't. There is no fixed answer, it varies from person to person. My personnal experience : I am a schizoaffective and asperger person, for ...

I'd say it is a low-impact theory. The original (2004) paper in which this was proposed has around 60 citations in Google Scholar. That's pretty low for a paper like this (if the theory were influential). For contrast a 2000 paper on the monoamine hypothesis for depression (which is far from being the first paper proposing it) has around 460 citations and ...

Probably not. The closest thing I am aware of is Mayor et al (2016) [The Effect of Chronic Dieting Goals on Auditory Perceptual Biases] where they propose the existence of “wishful hearing,” which establishes that ambient product sounds can be perceived as more spatially proximal when more desirable and thus lead to increased purchase intentions and ...

About intelligence: The subject of intelligence is broadly addressed in research in psychology, one of the most supportive theories is Spearman's bifactorial theory of intelligence, in this theory the factor g is a huge stable factor that explains the common variance (in scores) to all the different cognitive tasks that can be put to a person. Although ...

The only required degree to become a psychiatrist is a doctoral degree (M.D.). Using your example, yes those people could train to become psychiatrists. After passing the Medical College Admission Test (MCAT) and going through med school, most students undergo a psychiatric residency (aka. clerkship) where they are trained in different medical centers (...

Suppose someone were to see a psychiatrist, explain their life problems and such and then their psychiatrist concludes they are currently in a depressive episode. Their psychiatrist doesn't yet know if they have major depressive disorder - MDD - bipolar disorder or no disorder. Are there situations where someone in such scenario might be able to ...

This is not an a totally absurd proposal if dosage and time-related issues weren't a factor, but it is rife with practical difficulties otherwise. In schizophrenia patients, what you're talking about has been widely studied, under terms like "antipsychotic-evoked dopamine supersensitivity", "supersensitivity psychosis" (SP) etc. The ...

Short answer Taking dopamine antagonists leads to serious side effects, and stopping taking them leads to other, equally nasty side effects. None of them include happiness or feeling energized. Background So basically, based on our discussion in the comments, I think you are after the following: Is it viable to use a drug originally meant to suppress ...

Haha, yep. We don't know how depression or SSRIs work. We have hypotheses for both schizophrenia and depression - the dopamine hypothesis and the serotonin hypothesis. While I was conducting my research, I too was faced with this conundrum. And Dr. David Healy is one of the trailblazers of the side which says that it's all clever pharma marketing. As in ...

Depressants belong to a general class of drugs that decrease activity in one or more parts of the nervous system. Depression in the usual sense of the word comprises a particular subset of depressed states, particulars as it refers to lack of happiness or drive. Not all depressed states are considered depression in the common sense of the word. Similarly, ...
