In psychopharmacology, researchers are interested in any substance that crosses the blood–brain barrier and thus has an effect on behavior, mood, or cognition. Drugs are researched for their physiochemical properties, physical side effects , and psychological side effects.
APA does not recommend benzodiazepines for persons with depressive symptoms or a recent history of substance use disorder. APA guidelines state that, in general, pharmacotherapy of panic disorder should be continued for at least a year, and that clinical experience supports continuing benzodiazepine treatment to prevent recurrence.
The pharmacology of antidepressants is not entirely clear.. The earliest and probably most widely accepted scientific theory of antidepressant action is the monoamine hypothesis (which can be traced back to the 1950s), which states that depression is due to an imbalance (most often a deficiency) of the monoamine neurotransmitters (namely serotonin, norepinephrine and dopamine). [1]
Psychopharmacology studies a wide range of substances with various types of psychoactive properties. The professional and commercial fields of pharmacology and psychopharmacology do not typically focus on psychedelic or recreational drugs, and so the majority of studies are conducted on psychiatric medication. While studies are conducted on all ...
An implicit premise in neuropsychopharmacology with regard to the psychological aspects is that all states of mind, including both normal and drug-induced altered states, and diseases involving mental or cognitive dysfunction, have a neurochemical basis at the fundamental level, and certain circuit pathways in the central nervous system at a higher level.
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.
By this method, body diagrams can be derived by pasting organs into one of the "plain" body images shown below. This method requires a graphics editor that can handle transparent images, in order to avoid white squares around the organs when pasting onto the body image. Pictures of organs are found on the project's main page. These were ...
In the 1950s, scientists also became better able to measure levels of specific neurochemicals in the body and thus correlate these levels with behavior. [3] The invention of the voltage clamp in 1949 allowed for the study of ion channels and the nerve action potential. These two major historical events in neuropharmacology allowed scientists ...
