The morning after the night before: Alcohol-induced blackouts impair next day recall in sober young adults PMC

In the shallow encoding, immediate recall condition, 11 participants (47.8%) showed the effect and 12 (52.2%) did not. In the shallow encoding, delayed recall condition, 10 participants (43.5%) showed the effect, 11 (47.8%) did not, and 2 participants (8.7%) improved after-MBO. These results suggest that the deeply encoded conditions were most affected by binge-drinking until blackout. We originally hypothesised that people who experience a high volume of MBOs may perform differently in recall tasks compared to people who have never experienced diabetes and alcohol blackouts an alcohol-related memory blackout. Our data suggests that in general they do not perform differently, however, a lack of differences between controls and high frequency MBO participants here does not necessarily imply that the two groups of participants are equal. There is a paucity of neuroimaging work examining the impacts of memory blackouts, however, Squeglia et al. [25] examined structural changes in the brains of low-moderate frequency binge drinkers, and highlighted reduced grey matter volume in young adults compared to controls.

According to the University of California, San Francisco, one particular type of epileptic seizure that causes blackouts is a tonic-clonic seizure — also known as a grand-mal seizure. During this epileptic episode, people lose consciousness, and the body goes stiff (tonic phase). The muscles then contract, which may result in the jaw clamping shut (clonic phase). The American Heart Association (AHA) describe a syncope blackout as a short temporary loss of consciousness that happens when not enough blood reaches the brain. Some people define blackouts as a temporary loss of consciousness that typically lasts for a few minutes.

Alcohol and Diabetes: Additional Steps

Liquid sugars are quickly absorbed by the body, so those carbs won’t be much help in preventing or treating a low that may occur hours after you drink. Food, on the other hand, is digested gradually, so it provides better protection against lows. The best way to overcome diabetes and alcoholism is to seek professional treatment.

Despite the fact we could not measure source recollection, it is conceivable that recall performance for deeply encoded items would drop to a similar level seen for shallow encoding, after ingesting alcohol. (A, B) line graphs showing between control and MBO group mean accuracy (%) for freely recalled words in the depth of encoding task, both before and after ingesting alcohol. (A) displays data for deep and shallow conditions collapsed across https://ecosoberhouse.com/ delay, whereas (B) shows the differences between immediate and delayed recall conditions, collapsed across deep and shallow. Despite the increase in research on and our understanding of alcohol-induced blackouts, additional rigorous research is still needed. Studies examining potential genetic and environmental influences, as well as their interactions, are clearly warranted given recent research findings of Marino and Fromme (2015).

The Effects of Alcohol on Type 1 and Type 2 Diabetes

Finally, given the growing literature on alcohol-induced memory impairments and blackouts, a standardized assessment for alcohol-induced blackouts is sorely needed. Most of the existing research on alcohol-induced blackouts either uses a single item from the Rutgers Alcohol Problem Index or the investigator’s own description/definition of an alcohol-induced blackout. Moreover the frequency of occurrence for blackouts is currently measured in widely different ways, including dichotomous measures (e.g., Yes/No blackouts) and proportion of times drinking that blackouts were experienced (e.g., always, sometimes, never). In an effort to better characterize blackouts, researchers should collect detailed information about past and current alcohol consumption patterns, as well as other illicit drug use.

People with both diabetes and alcoholism and people with diabetes who often drink also increase their risk of worsening their symptoms. Alcohol can worsen diabetes by blocking the production of glucose in the liver, which can result in very low blood sugar levels. The symptoms of low blood sugar (hypoglycemia) are usually similar to the side effects of alcohol, making it difficult to differentiate the two. Low blood sugar and alcohol can both cause symptoms like blurred vision, slurred speech, sedation, and impaired coordination. The aim of this study was to examine the associations between alcohol consumption and the risk of vascular events and death in patients with type 2 diabetes, with special reference to microvascular outcomes, level of alcohol consumption, and the predominant type of alcoholic drink.

Alcohol Use at Baseline and Study Outcomes

The delay component (three minutes) within the depth of encoding task was included to assess the impact of frequent MBO events on memory consolidation over time. To conclude, the three experiments presented here examined episodic memory performance in people who experience alcohol-related memory blackouts. To the best of our knowledge, this is the first paper to compare frequent blackout participants when sober, after alcohol, and after blackout, and further, contrast their performance with a control group before and after alcohol. We hypothesised that in comparison to controls, MBO participants may show greater deficits in memory performance after drinking alcohol yet found limited group differences before and after alcohol. However, we show that after experiencing a blackout, deficits remained in all three experiments to varying degrees (individual participant data), and group data highlighted significant after-MBO effects in the serial recall and depth of encoding tasks.

In our free recall experiment, both groups showed similar recall accuracy when sober and after drinking alcohol, where the amount of words recalled decreased at the same rate. Additionally, within the MBO group, recall after-MBO was variable across the group, with 10 participants showing a deficit in relation to sober conditions, while 12 showed no deficit. This pattern of variability may suggest a weak effect size within the overall population of individuals who blackout frequently for free recall, and mirrors findings across studies of hangovers in social drinkers. Some studies have shown no deficit in memory performance [see, for example, 52, 53], but others have found impaired performance during hangovers in free recall tasks [54, 55]. Possibly the differences between findings reflects the design of experiments, either measuring in the laboratory or relying on self-reported drinking behaviour.
