The chemical imbalance hypothesis states that a chemical imbalance within the brain is the main cause of psychiatric conditions and that these conditions can be improved with medication which corrects this imbalance. In that, emotions within a "normal" spectrum reflect a proper balance of neurotransmitter function, but abnormally extreme ...
Electrolyte imbalance, or water-electrolyte imbalance, is an abnormality in the concentration of electrolytes in the body. Electrolytes play a vital role in maintaining homeostasis in the body. They help to regulate heart and neurological function, fluid balance , oxygen delivery , acid–base balance and much more.
Biological psychiatry or biopsychiatry is an approach to psychiatry that aims to understand mental disorder in terms of the biological function of the nervous system.It is interdisciplinary in its approach and draws on sciences such as neuroscience, psychopharmacology, biochemistry, genetics, epigenetics and physiology to investigate the biological bases of behavior and psychopathology.
For years, a chemical imbalance of serotonin has been widely viewed as the culprit for depression, resulting in the widespread use of antidepressants. The study published this week in the journal…
Chemical signaling between neurons is mediated by neurotransmitters, neuropeptides, hormones, neuromodulators, and many other types of signaling molecules. Many neurological diseases arise due to an imbalance in the brain's neurochemistry. For example, in Parkinson's Disease, there is an imbalance in the brain's level of dopamine.
Trephination was when a small hole was drilled into a person's skull to let out demons, as that was an earlier belief for mental disorders. Bloodletting is when a certain amount of blood was drained out of a person, due to the belief that chemical imbalances resulted in mental disorders.
The serotonin "chemical imbalance" theory of depression, proposed in the 1960s, [35] is not supported by the available scientific evidence. [ 35 ] [ 36 ] SSRIs alter the balance of serotonin inside and outside of neurons: their clinical antidepressant effect (which is robust in severe depression [ 37 ] ) is likely due to more complex changes in ...
The Emperor's New Drugs: Exploding the Antidepressant Myth is a 2009 book by Irving Kirsch, arguing that the chemical imbalance theory of depression is wrong and that antidepressants have little or no direct effect on depression but, because of their common or serious side-effects, they are powerful active placebos.
