Along with risky behavior and memory loss, the neurological impact of repeated blackout periods can cause significant damage to brain function. Chronic blackout drinking can result in permanent cognitive impairments, increased risk of alcohol use disorder, potential brain cell destruction, and a decrease in the ability to form and retain memories. After a traumatic event, a person may drink to deal with anxiety, depression, and irritability.
What Causes Blackouts?
Difficulties Engaging in Goal-Directed Behavior also mediated the relationship between PTSD symptoms and alcohol-related consequences in the full sample, and these results remained significant for women when the sample was split by sex. It is possible that for women, PTSD symptoms, especially “difficulty concentrating,” interferes with motivation to attend to tasks when distressed. For women struggling with intense negative affect who have difficulty conceiving and tracking even short-term goals, a pattern of risky alcohol use could develop due to the immediate relief it provides. Past research has found relationships between PTSD hyperarousal symptoms (which includes difficulty concentrating) and alcohol consumption (Duranceau, Fetzner, & Carleton, 2014). Further, in that study distress tolerance had an indirect effect on alcohol consumption through the pathway of hyperarousal symptoms.
Research shows that support from family and friends also can be an important part of recovery. Emotionally, she alternated between feeling apathetic, numb, and alienated from others and feeling “on edge,” hypervigilant, and anxious. She avoided numerous situations reminiscent of her earlier experiences, including her childhood home and movies and news items involving child abuse. She also avoided discussing her abuse history with others and attempted to suppress her own memories of what happened. She felt unable to control many of these PTSD symptoms except by drinking alcohol, but even alcohol provided only temporary relief. Ultimately, each veteran’s experience is unique, and there is no experience that you have to go through to be considered traumatized.
The constant reexperiencing of the PTSD symptoms causes an initial increase in endorphin activity followed by a rebound withdrawal. One study conducted with Vietnam combat veterans with chronic PTSD showed that their alcohol use generally began after the onset of PTSD symptoms. For many of the patients, alcohol consumption continued to increase as their symptoms of PTSD increased (Bremner et al. 1996). From a clinical perspective, better understanding of the correlates of blackout may help inform and tailor intervention efforts. Data from this study suggest that racial discrimination and drinking to cope may be especially relevant for blackout in diverse samples of Veterans, in which case screening for and preventing these experiences becomes a priority.
Unlike age-related memory decline or the effects of certain medications, PTSD blackouts are typically episodic and closely tied to traumatic experiences. They may also be accompanied by other dissociative symptoms, such as depersonalization or derealization, which are less common in other forms of memory loss. Dealing with military-related trauma, whether it’s PTSD, combat trauma, or sexual trauma, may be too much to handle on your own.
Someone in a blackout will have no memory of having been given three words to remember and may think you are playing a trick on them. The movie Memento illustrated this condition on a permanent basis due to brain injury. The most common cause of permanent blackouts is thiamine deficiency due to poor diet in chronic alcoholics, called Korsakoff’s Syndrome. During a blackout, the mind is not functioning properly because the brain is not functioning properly. The fundamental mental dysfunction is that short-term memory is no longer being uploaded into longer-term memory.

- Smith and Cottler, in The Epidemiology of Post-Traumatic Stress Disorder and Alcohol Use Disorder, describe the changes in the Diagnostic and Statistical Manual of Mental Disorders (DSM) definitions of AUD and PTSD.
- This investigation examined facets of emotion dysregulation as potential mediators of the relationship between PTSD symptoms and alcohol-related consequences and whether differences may exist across sexes.
- On her way home from the same crime prevention class, Jan encounters another man who points a gun at her head and demands her money.
- Participants rated how often they were “feeling down, depressed, or hopeless” and had “little interest or pleasure in doing things” on a scale from 0 (not at all) to 3 (nearly every day).
How can I find a clinical trial for PTSD?
These early experiences of physical or sexual abuse can have a life-long effect. Early experience with trauma (e.g., a history of childhood sexual or physical abuse) also heightens a person’s susceptibility to severe PTSD symptoms as an adult. For example, victims of childhood physical and sexual abuse are at higher risk for developing PTSD symptoms following traumatic events in adulthood (Breslau et al. 1999). Human studies have also shown that traumatic events can increase endorphin activity.
In Behavioral Treatments for Alcohol Use Disorder and Post-Traumatic Stress Disorder, Flanagan and colleagues describe evidence-supported behavioral interventions for treating AUD, PTSD, and co-occurring AUD and PTSD. They also examine the debate regarding sequential versus integrated treatment models. The experience can be compared to snapping photos only to discover later that there was no film in the camera. The difference with a blackout is that, not only are there no pictures in the camera, but your mind has absolutely no memory of having taken the pictures. Twin studies show that if one twin is prone to blackouts, the other is much more likely to also be prone if they are identical, rather than fraternal. Identical twins share 100 percent of their DNA, while fraternal twins only share 50 percent.
Why Alcohol Blackouts Are Nothing to Joke About

Addressing trauma through various therapeutic approaches, including trauma-focused therapy, EMDR, and motivational interviewing, can effectively reduce PTSD symptoms and substance misuse. Complex trauma and AUD are often intertwined, as childhood trauma increases the risk of developing AUD. One 2020 study explored the direct and indirect links between types of childhood trauma to PTSD and alcohol misuse. Embarking on the journey to recovery from addiction involves navigating the challenging phase of substance withdrawal.
An opioid antagonist such as a naltrexone would block the endorphin response and reduce the desire for alcohol. In an animal study (Volpicelli et al. 1986), we have shown that the opioid blocker naltrexone can prevent increased alcohol consumption following trauma. Rats will typically increase their alcohol consumption after several days of 1-hour sessions of brief electric footshocks.
Historical Link Between PTSD and Alcohol Addiction
For example, patients with PTSD will experience numbness or analgesia when simply exposed to reminders of the trauma (Pitman et al. 1990). We know the analgesia is attributable to a release of endorphins because drugs that block endorphins (opioid blockers) also block the analgesia in PTSD patients. In one study, Vietnam veterans with PTSD were shown a videotape of combat and asked to rate the pain intensity of a hot stimulus. After viewing the videotape the hot stimulus was less painful (i.e., the trauma reminder produced analgesia). However, when the opioid receptors were blocked with naloxone, an injectable opioid receptor blocker, there was no analgesia (van der Kolk et al. 1989).
