Experiencing “lost time” after a night of drinking is often portrayed in pop culture as a sign of an epic party. The reality is much more sinister. Memory loss related to alcohol consumption can be an indicator of serious substance abuse issues.
What Is a Blackout?
The term blackout refers to the memory loss that sometimes accompanies alcohol consumption. Blackouts can be either temporary or permanent. Someone with a temporary blackout may later remember what happened with visual or verbal cues from others, but a permanent blackout means that memories are unlikely to be recovered.
Someone who experiences a blackout typically has a BAC of 0.15 or higher—which is high enough that alcohol poisoning is considered a real risk. (Remember, 0.08 BAC is considered legally drunk.) However, age, weight, gender, time of last meal, speed of drinking, and type of alcohol consumed can all affect how a person’s body processes alcohol.
Some researchers suggest that using opioids, benzodiazepines, or marijuana with alcohol increases the risk of blackouts. There is also evidence that certain individuals have a genetic predisposition to blackouts while drinking due to differences in how their bodies process alcohol.
A blackout won’t end until a person’s body has processed the alcohol they’ve consumed, and they are able to once again form new memories in the brain. If someone continues drinking while experiencing a blackout, they could be unable to form memories for hours or even days.
What Are the Signs of a Blackout?
It’s not easy for a casual observer to tell when someone is experiencing an alcohol-related blackout because the person will still be awake and interacting with others. They will simply exhibit symptoms of severe intoxication, such as:
- Difficulty standing
- Difficulty walking
- Slurring words or other difficulty talking
- Impaired judgment and decision-making
- Impaired vision
- Complaints of headaches or nausea
Even the spouses of individuals with severe drinking problems often report that they are unable to tell their partner is experiencing a blackout until they discover the memory lapse as they are discussing events the next day.
Why Are Blackouts Dangerous?
Blackouts are dangerous because they cause injury to the frontal lobe of the brain. Over time, this can lead to changes in personality, mood, and behavior even when a person is sober.
Blackouts also increase the risk of negative behavior, such as:
- Falling or otherwise hurting oneself
- Causing a drunk driving accident
- Fighting with others
- Having unprotected sex
- Engaging in vandalism, theft, or other forms of criminal activity
Do Blackouts Indicate a Drinking Problem?
It is hard to say with certainty that someone has a drinking problem based on one factor alone. For example, a blackout that a teenager experiences after experimenting with alcohol at a party could be a one-time case of poor judgment. However, any drinking that progresses to the level where someone is unable to remember the events that have occurred is definitely a cause for concern.
Other signs that suggest an evaluation for a substance use disorder is needed include:
- Ignoring other responsibilities in order to spend more time drinking
- Declining performance at school or work
- Drinking alone or in secret
- Lying to friends and family about the amount of alcohol consumed
- Experiencing withdrawal symptoms when alcohol consumption stops
- Mixing alcohol with other drugs
- Being unable to self-regulate alcohol consumption
- Having financial problems due to the amount of money spent on alcohol
- Believing that drinking is the only way to feel “normal”
If you are worried about a loved one’s alcohol consumption, do not push your concerns aside. Addressing the issue without shame or judgment can open the door to better understanding. Addiction is a progressive illness, so someone who is in the early stages of alcoholism will not get better without treatment.
