Recovery of Cognitive Functioning in Alcoholics PMC

In a loose sense, the cognitive “switchboard” of the alcoholic appears impaired but apparently can be stimulated to more efficient activity by the repetition of appropriate cognitive demands. A quick review of this issue of Alcohol Health & Research World reveals the impact of chronic excessive alcohol use on cognitive functioning. Additionally, those that experience memory blackouts commonly from excessive drinking are more likely to participate in behaviors that could lead to other consequences. Drunk driving, unprotected sexual activity, crime, and violence are to be expected of those that have a blood alcohol content level high enough to induce memory lapse. Also, those that commonly experience memory blackouts from alcohol are at a higher risk of using other drugs and developing other addictions.

Why Can’t I Remember Blackout Memories

However, long-term effects of chronic alcohol abuse — such as liver damage, nerve damage and increased cancer risk — do not always go away. For example, people with minor liver problems can recover from heavy drinking if they stop drinking. The https://rehabliving.net/influence-of-genetic-background-in-alcohol/ authors concluded that the blackouts were caused by an inability to transfer information from short-term to long-term memory when blood alcohol levels were rising. The results were published in the Quarterly Journal of Studies on Alcohol.

According to Gray, instead of standing on the ground of reality, we actually stand on the ground of beliefs. Beneath beliefs are conclusions, assumptions, what’s relevant to one’s needs, and our experiences and observations about reality. Let’s break down an example to see how this pyramid works in real life.

It also might help to connect what you’re trying to remember to a favorite song or a familiar saying or idea. You’re more likely to forget things if your home is cluttered or your notes are in disarray. Keep track of tasks, appointments and other events in a notebook, calendar or electronic planner. You might even repeat each entry out loud as you write it down to help keep it in your memory. Keep your wallet, keys, glasses and other essential items in a set place in your home so they are easy to find. Therapy combined with an AUD program tends to lead to a high recovery success rate.

The latter study found that women experienced the side effects after drinking only half as much as men. Test findings from a wide group of studies show that alcoholics are remarkably free of impairment of general intelligence. Their cognitive deficits are more consistently revealed using specific tests of abstract reasoning and visual perception. In addition, alcoholics have not consistently shown learning and memory deficits despite the fact that more severe versions of these impairments are symptoms of Wernicke-Korsakoff syndrome (see Parsons et al. 1987).

How Heavy Alcohol Use Can Damage Memory Function

Subjects were asked to recall details regarding these stimuli 2 minutes, 30 minutes, and 24 hours after the stimuli were shown. Half of the subjects reported no recall for the stimuli or their presentation 30 minutes and 24 hours after the events, though most seemed to recall the stimuli 2 minutes after presentation. Lack of recall for the events 24 hours later, while sober, represents clear experimental evidence for the occurrence of blackouts. For all but one subject in the blackout group, memory impairments began during the first few hours of drinking, when BAC levels were still rising. The average peak BAC in this group, which was roughly 0.28 percent, occurred approximately 2.5 hours after the onset of drinking.

1. Some participants joined at the 1 month mark, meaning 23 individals didn’t have scans taken at 1 week, and only 40 of the total 88 continued to abstain from alcohol for the full period.
2. These methods have shown promise in preliminary studies and warrant further research.
3. An even more critical change was that the alcoholic patients’ ability to learn and implement a treatment component became a criterion for judging whether the alcoholic had successfully benefited from the cognitive rehabilitation program.
4. “The few longitudinal studies investigating cortical thickness changes during abstinence are limited to the first month of sobriety,” writes the team, led by psychiatrist and behavioral scientist Timothy Durazzo from Stanford University.

Interestingly, these reminders trigger at least some recall of the initially missing information. Research suggests that fragmentary blackouts are far more common than those of the en bloc variety (White et al. 2004; Hartzler and Fromme 2003b; Goodwin et al. 1969b). A pair of studies — one published in Psychological Medicine and the other in Alcoholism, Clinical and Experimental Research — found that men and women both experienced brain shrinkage and memory problems after heavy alcohol consumption.

Losing a night of memories may not seem like a big deal, but prolonged and excessive drinking can have long-term or even permanent effects on our memory, which we’ll get into. These results provide encouragement and a new understanding of brain recovery after quitting alcohol, though due to the small sample size and lack of diversity, they may not be generalizable. Also, it’s important to note these findings don’t indicate whether the changes had any effect on brain function.

There are two types of blackouts; they are defined by the severity of the memory impairment. The most common type is called a “fragmentary blackout” and is characterized by spotty memories for events, with “islands” of memories separated by missing periods of time in between. Unreliable sources can lead to memory errors and sometimes false beliefs about behaviors during a forgotten time-period. This may be true not only for boozy blackouts but for other past experiences, whether it’s cobbling together childhood memories or even in cases of wrongful conviction. Some brain cells are irreversibly lost from alcohol abuse, according to study researcher Natalie May Zahr of the Stanford University School of Medicine.But alcohol also shrinks the volume of brain matter, a process that can be reversed with sobriety. Research conducted in the past few decades using animal models supports the hypothesis that alcohol impairs memory formation, at least in part, by disrupting activity in the hippocampus (for a review, see White et al. 2000b).

Despite advice from experts and beer commercials, most people do not drink responsibly. More than 50 percent of adults have blacked out at least once in their lives. The number isn’t surprising considering almost 25 percent of adults binge-drink every month, according to stats from the National Institute on Alcohol Abuse and Alcoholism. If you focus on the information that you’re trying to remember, you’re more likely to recall it later.

My belief came from the observation of people drinking smoothies for weight loss and the experience of losing water weight after a heavy drinking session. As maintaining an ideal body weight was relevant to me, I captured the information and formed an assumption that liquids equal weight loss. The assumption led to the conclusion that drinking alcohol wouldn’t make me gain weight.

Being with a loved one who drinks regularly and loses control can be scary, and it is as scary for a man to be on the receiving end as the stereotypical women scenario. People tend to either be a happy drunk or a sad and angry drunk, and there is a direct relationship between alcohol and aggression. Even mild-mannered people can become angry when there is no emotional regulation in place.

That is why people experience a range of memory loss symptoms when they binge-drink. Alcohol can cause minor memory loss, such as being unable to remember details of a conversation after a few drinks, or major memory loss, such as forgetting hours of time after taking shots. In addition, information presented to patients should be concrete rather than abstract; active strategies that emphasize practice may be used. Also, treatment professionals must not depend on alcoholics being able to demonstrate “quick thinking” in high-risk situations that may trigger drinking. Alcoholics must be able to practice with specific behaviors in treatment that reduce risk until these behaviors are as automatic as possible.

The human brain, showing the location of the hippocampus, the frontal lobes, and the medial septum. It’s conceivable they both could have had a blackout about the same event, although that begins to get a little bit less likely.

Similarly, the combination of alcohol and THC, the primary psychoactive compound in marijuana, produces greater memory impairments than when either drug is given alone (Ciccocioppo et al. 2002). Given that many college students use other drugs in combination with alcohol (O’Malley and Johnston 2002), some of the blackouts reported by students may arise from polysubstance use rather than from alcohol alone. Indeed, based on interviews with 136 heavy-drinking young adults (mean age 22), Hartzler and Fromme (2003b) concluded that en bloc blackouts often arise from the combined use of alcohol and other drugs.

The question remains, however, whether such extensive damage can be reversed after abstaining from alcohol. Researchers have studied the effects of abstinence on the brains of alcohol-dependent individuals by comparing subjects recovering from years of alcohol abuse with those who do not drink or drink minimally. Scientists have also investigated changes in brain volume in initial versus sustained abstinence in one set of https://rehabliving.net/ subjects. Additionally, when they returned to a low-risk level of drinking — no greater than three drinks per day for men or 1.5 drinks for women — the volume of these brain regions more closely resembled that of people who did not drink at all. But, if you experience blackouts and consequences ensue because of them, yet you still cannot stop drinking alcohol, the chances are high that you have an addiction to alcohol.

Treatments themselves must be improved, and/or they must be matched to the functional cognitive level of the alcoholic before the true importance of differences in cognitive functioning can be identified and evaluated. For example, two recent reports on a patient-treatment matching study (Cooney et al. 1991; Kadden et al. 1989) provide somewhat unintended evidence for the importance of matching treatment complexity to patients’ cognitive resources. Perhaps this result is not so surprising, however, when the large amount of information that must be acquired during coping skills training is compared with the considerably lighter informational demands of interactional therapy. In more recent studies (Forsberg and Goldman 1987), practice on demanding visuospatial learning tests has resulted in performance improvements on a wide variety of other cognitive tests, but only if the tests were presented within the same sensory modality. For example, practice on some visually presented tests resulted in improved performance on other visually presented tests but did not seem to improve performance on tests that depended primarily on touch.

Researchers believe a person may be unable to access the memory unless a reminder triggers it. However, scientists at the Washington University School of Medicine found in a 2011 study that alcohol didn’t kill brain cells. Instead, they found that alcohol interfered with receptors in the brain, making them produce steroids that interrupted the learning and memory-building process. On the other hand, some researchers have reported the relationship between cognitive deficits and treatment success to be modest at best or even inverse. They note that adding indicators of patients’ cognitive status to statistical analyses does not increase the accuracy of the treatment outcome predictions that result from using only basic sociodemographic variables.

But when you add the effects of heavy alcohol use, memory loss can be very serious. The hippocampus plays a significant role in helping people form and maintain memories. When normal nerve activity slows down, short-term memory loss can occur. Take my old belief that “anything liquid won’t make me gain weight” as an example.
