GLP-1 drugs may protect the brain from inflammation, some studies say, but others warn they may increase depression risk. Image credit: James Manning – PA Images/Getty Images.
More specifically, it looked at the effect of methylphenidate (brand names Ritalin, Concerta), a stimulant, and atomoxetine (Strattera), a non-stimulant, on the brain. It concluded that both drugs ...
Behavioral neuropharmacology focuses on the study of how drugs affect human behavior (neuropsychopharmacology), including the study of how drug dependence and addiction affect the human brain. [2] Molecular neuropharmacology involves the study of neurons and their neurochemical interactions, with the overall goal of developing drugs that have ...
Studies have shown that a GLP-1 drug, exenatide, sufficiently crosses the blood-brain barrier in rodent models of Parkinson’s disease, leading to improvements in motor performance, behavior ...
The specific interaction between drugs and their receptors is referred to as "drug action", and the widespread changes in physiological or psychological function is referred to as "drug effect". [2] These drugs may originate from natural sources such as plants and animals, or from artificial sources such as chemical synthesis in the laboratory.
[19] [22] As a serotonin receptor agonist, LSD's precise effects are not fully understood, but it is known to alter the brain’s default mode network, leading to its powerful psychedelic effects. [12] [23] [24] The drug was first synthesized by Swiss chemist Albert Hofmann in 1938 and became widely studied in the 1950s and 1960s.
How Ozempic works in the brain. The effects that semaglutide has on insulin production and feeling full all start in the brain, Dr. Ania Jastreboff, associate professor at Yale School of Medicine ...
By altering receptor function in one part of the brain, abnormal activity can be induced in other parts of the brain due to the same type of receptor changes. A common example is the effect of D 2 altering drugs (neuroleptics) which can help schizophrenia, but cause a variety of dyskinesias by their action on motor cortex.
