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.
One form of behavioral neuropharmacology focuses on the study of drug dependence and how drug addiction affects the human mind. Most research has shown that the major part of the brain that reinforces addiction through neurochemical reward is the nucleus accumbens. The image to the right shows how dopamine is projected into this area.
Researchers found that 63% of lifetime heavy cannabis-using participants and 68% of recent cannabis users showed reduced brain activity during their working memory task. “We found that brain ...
A review and meta-analysis published in Neuroscience and Biobehavioral Reviews in May 2024 highlighted the benefits that prescription drugs for ADHD can bring to brain health.
Alcohol acts as a general central nervous system depressant, but it also affects some specific areas of the brain to a greater extent than others. Memory impairment caused by alcohol has been linked to the disruption of hippocampal function—particularly affecting gamma-Aminobutyric acid (GABA) and N-methyl-D-aspartate (NMDA) neurotransmission which negatively impacts long-term potentiation ...
Drug-induced amnesia is amnesia caused by drugs. Amnesia may be therapeutic for medical treatment or for medical procedures, or it may be a side-effect of a drug, such as alcohol , or certain medications for psychiatric disorders, such as benzodiazepines . [ 1 ]
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.
A recent study found significant reductions in opioid overdose and alcohol misuse among people taking GLP-1 drugs like Ozempic. These medications interact with a part of the brain that can help ...
