Several forms of memory are impaired by chronic ecstasy use; [22] [92] however, the effects for memory impairments in ecstasy users are generally small overall. [93] [94] MDMA use is also associated with increased impulsivity and depression. [8] Serotonin depletion following MDMA use can cause depression in subsequent days.
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 ...
Both substance use and alcohol can cause both long-term and short-term memory loss, resulting in blackouts. The most commonly used group of prescription drugs which can produce amnesia are benzodiazepines, especially if combined with alcohol, however, in limited quantities, triazolam (Halcion) is not associated with amnesia or memory impairment.
The observed effects on memory and learning, they said, showed long-term cannabis use caused "selective memory defects", but "of a very small magnitude". [85] A study by Johns Hopkins University School of Medicine found that heavy cannabis use is associated with decrements in neurocognitive performance even after 28 days of abstinence.
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 ...
Ecstasy users who additionally used amphetamine were included as results from prior studies have indicated that concurrent amphetamine use may mediate the effects of MDMA on orientation neurons. [2] [3] [4] The results of the study indicated that the amphetamine abstinent Ecstasy group showed a broader tuning bandwidth than the controls. [2]
Exercise can also prompt the birth of new neurons in the hippocampus, which is an area of the brain that’s essential for memory and learning, Dr. Vernon Williams, sports neurologist and founding ...
Alcohol-related brain damage [1] [2] alters both the structure and function of the brain as a result of the direct neurotoxic effects of alcohol intoxication or acute alcohol withdrawal. Increased alcohol intake is associated with damage to brain regions including the frontal lobe , [ 3 ] limbic system , and cerebellum , [ 4 ] with widespread ...
