The Yahoo website provided this article on the experiences known as blackouts. I suppose like everything else related to drinking, the number of blackouts has increased during the pandemic. And with that have come questions such as this one:
Here’s a fairly recent review of research:
Some blackouts, by the way, are partial, meaning not all memories have been lost. Others appear to be total. There the drinker recalls nothing of events from the period of intoxication.
I’ve also run into the term ‘pseudo blackout’, which one former patient described as: “Some things I really didn’t remember, and other things I preferred not to.”
Alcoholic blackouts are specific to the experience of intoxication. They fall into two broad categories.
Fragmentary: partial memory loss, often recoverable later. An example: Marsha remembers attending the wedding, but not the long conversation she’s told by others she had with her friend Liza. “At first I thought they were teasing me. I had no memory at all of talking to Liza. But when I asked my roommate, she confirmed it. According to her, Liza and I talked for fifteen or twenty minutes. She was sitting on the sofa right next to us.”
Example 2: A 27 year old man went bar-hopping with friends in the City. The following morning he awoke with no recollection of how he got home or where he left his car. Later that night, while watching TV, he found himself picturing the vehicle in front of a bodega around the corner from where they’d been drinking. A friend gave him a ride to pick up the car. He never did recall who took him home the night before, however.
En bloc: this is memory loss both total and permanent for a specific period while intoxicated. I haven’t heard of cases where such memories did eventually return, but there may be some in the literature.
Example: A 46 year old man with a history of alcoholism reports total memory loss for a two-week period spent in Las Vegas. He learned to his chagrin that he’d managed to accumulate more than $200,000 in gambling debts at three different casinos.
Just FYI, here’s an earlier piece we did on some rather famous blackouts.
Three factors that are commonly believed to elevate one’s risk of a blackout:
- Consuming large amounts of alcohol in a very short period.
- Being an inexperienced drinker or having a low tolerance. Think of the stories that emerge from fraternity rush week at the local college.
- Using other drugs along with alcohol. CNS depressants, naturally, but other classes of drugs may also play a role. One patient explained that before going out to a club, he and his roommate liked to consume MDMA (AKA Molly). They followed that up with some heavy drinking. He explained he just liked the way the two drugs combined to “balance” his high. He made sure to carry along a few Xanax in case he required extra sedation during the evening. It isn’t hard to see how this could lead to a blackout.
Probably the most dramatic example I’ve encountered involved a woman who reported blacking out almost immediately after the first drink — recalling nothing that happened subsequently until she sobered up again. Her companion used the old-time technique of wrapping her up in a sheet or blanket to prevent her from further drinking. “That’s what it took,” she shrugged. “I guess I’m a rowdy drunk.”
