Memory impairment during acute intoxication involves dysfunction of episodic memory, a type of memory encoded with spatial and social context. Recent studies have shown that there are multiple memory systems supported by discrete brain regions, and the acute effects of alcohol and learning and memory may result from alteration of the ...
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] It is seen also with slow acting parenteral general anaesthetics. [citation needed]
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.
A 2015 review concluded that "Nicotine acts as a gateway drug on the brain, and this effect is likely to occur whether the exposure is from smoking tobacco, passive tobacco smoke or e-cigarettes." [25] Nicotine may have a profound impact on sleep. [26] The effects on sleep vary after being intoxicated, during withdrawal, and from long-term use ...
Nootropics are touted as “smart drugs” meant to improve cognitive performance. But there’s a lot we still don’t know about them. Do nootropics really boost focus and memory?
One prevailing theory which aims to explain this sex difference identifies estrogen levels in the body as an important factor relating to caffeine's effect on memory performance [20] As a result, the female menstrual cycle (which influences overall estrogen levels in the body) may play a role in modifying the effect of caffeine on memory.
Story at a glance University of Maryland researchers examined MRI images and medical records of more than 8,300 children aged 9 to 10. The team linked lack of sleep to mental health issues like ...
