As with any substance use, alcohol may increase the undesirable symptoms of narcolepsy.
Article at a Glance:
Alcohol use is not proven to be a distinct cause of the sleep disorder narcolepsy.
However, the use of alcohol could create narcolepsy-like symptoms for the person drinking alcohol.
If a person with narcolepsy ingests alcohol, they may increase the challenging symptoms they are already dealing with.
Can Alcohol Consumption Cause Narcolepsy?
Alcohol is commonly thought of as a sedating or calming substance. While alcohol may induce a sleepy sensation in people who have consumed a few drinks, sleep quality tends to decrease after ingesting alcohol. Someone who drinks a glass or two of wine may feel drowsy after drinking. However, this is not likely, as alcohol consumption makes a person more likely to wake up during the night, worsening their overall quality of sleep.
This sleep disruption typically occurs during the second half of the sleep period once alcohol’s relaxing effect wears off. The disruption keeps the body from experiencing the critical REM state and may lead to daytime fatigue and sleepiness. A continued cycle of consumption and REM disturbances can lead to symptoms similar to those experienced with narcolepsy, like:
- Daytime sleepiness
- Disrupted REM sleep
- Vivid dreams
- Possible hallucinations caused by lack of sleep
Alcohol should be avoided before or close to bedtime. It prevents people from getting the deep sleep and REM sleep they need because alcohol keeps them in the lighter stages of sleep.
Hypocretin is an important chemical produced by the brain for regulating wakefulness and REM. Lack of the chemical in the brain can cause narcolepsy-like symptoms.
Alcohol-induced narcolepsy is caused by alcohol consumption and characterized by overwhelming daytime drowsiness and sudden attacks of sleep. If the urge becomes irresistible, patients fall asleep for periods lasting from a few minutes to several hours. These episodes of random sleep can occur at inappropriate times and places such as while driving, at bars, work and restaurants. In turn, people with sleep disorders are also at risk to develop substance use disorders in an attempt to induce sleep. Most often, the substances of abuse for individuals with sleep disorders are alcohol, narcotic medications and benzodiazepines.
Alcohol-induced narcolepsy should not be confused with passing out from excessive drinking, which usually consists of a person falling asleep, waking up, drinking more, actively engaging in activities and then falling asleep again. This cycle may repeat throughout the day and into the evening.
Co-Occurring Treatment of Narcolepsy With Alcohol Abuse
Patients who meet the formal diagnostic criteria for narcolepsy and either alcohol use disorder or addiction would need to treat both disorders simultaneously. Trying to address one disorder while ignoring the other would be counterproductive and result in negative effects.
Someone with these co-occurring diagnoses requires combined treatment. The purpose of the combined treatment is a long-term success, including aftercare planning. Ultimately, with a comprehensive treatment approach, people who suffer from narcolepsy and alcohol abuse can embrace a healthy life in recovery.
