This resource outlines alcohol toxicology, including how alcohol is absorbed, distributed, and eliminated and how concentration estimates are interpreted. It explains that food and drinking patterns affect absorption and peak levels, while the cited Mellanby research describes differences between subjective intoxication and objective performance as blood alcohol concentration rises and falls.
The article collection examines how sleep loss can affect the formation of new memories. A study summarized in the resource found that one night without sleep reduced hippocampal activity during episodic-memory encoding and worsened later retention, while another found that even shallow sleep could impair subsequent memory performance.
The resource surveys research on posttraumatic stress disorder and substance use, including diagnostic overlap and patterns of use among affected populations. Its studies include findings on drug-use reports by veterans seeking PTSD care and on links between PTSD symptoms, coping motives, and marijuana use, alongside reviews of treatment and co-occurring conditions.
The article systematically reviews whether alcohol’s effects at a given blood alcohol concentration differ while the level is rising versus falling. It reports lower perceived intoxication and greater willingness to drive on the descending curve, while objective driving and inhibitory-control measures were generally worse during that same phase.
This collection reviews research on the co-occurrence of bipolar disorder and substance use, including how the combination may affect diagnosis and illness course. The studies discuss high comorbidity, possible roles for impulsivity, and limited controlled treatment evidence, with one review describing integrated medication and psychosocial approaches as promising but in need of further study.
The article collection describes how benzodiazepines can interfere with forming and retaining new memories. The reviewed material links anterograde amnesia to impaired consolidation, with the extent of impairment varying by dose and drug properties, and notes that some groups face greater risk of adverse central nervous system effects.
The resource reviews research on alcohol’s effects on sleep architecture, including changes in sleep onset and the balance of REM and non-REM stages. The studies summarized describe more deep sleep and less REM early in the night, with later sleep often becoming lighter and more interrupted as alcohol is metabolized.
The article examines why drinkers may underestimate how much alcohol they have consumed or how intoxicated they are. Its cited studies report estimation errors associated with heavier drinking and, among bar patrons already above the legal driving threshold, frequent underestimation of breath alcohol concentration, especially among women and people under 21.
This resource explains how alcohol can affect multiple brain systems involved in memory, judgment, coordination, and behavior. It discusses hippocampal disruption and receptor activity, and summarizes research associating binge drinking and blackout history with altered frontal-lobe neurochemistry and cognitive effects of alcohol use disorders.
The article reviews evidence that alcohol changes the timing and structure of sleep in healthy people. It describes faster sleep onset and more deep sleep early in the night, followed by greater disruption later, and summarizes research linking intoxication with reduced REM sleep and poorer reported sleep quality.
