For example, they are investigating whether the net increase in synaptic serotonin levels results from alcohol’s direct actions on molecules involved in serotonin release and uptake or from more indirect alcohol effects. Serotonin is an important brain chemical that acts as a neurotransmitter to communicate information among nerve cells. Serotonin’s actions have been linked to alcohol’s effects on the brain and to alcohol abuse. Alcoholics and experimental animals that consume large quantities of alcohol show evidence of differences in brain serotonin levels compared with nonalcoholics.
Scientists postulate that this syndrome represents the hyperactivity of neural adaptive mechanisms no longer balanced by the inhibitory effects of alcohol (see figure). Research shows that people with alcoholism find it difficult to recover from traumatic events. This is possibly because of the effects of alcohol abuse, which can actually change brain activity. These examples demonstrate that serotonin interacts with other neurotransmitters in several ways to promote alcohol’s intoxicating and rewarding effects.
Similar to the other modalities described here, administration of these psychosocial treatment strategies for alcohol problems can be less straightforward with individuals who have comorbid anxiety and AUDs. Clients with social anxiety disorder, for example, may have difficulties with several elements of standard psychosocial approaches for alcoholism. Many treatment programs, as well as AA, heavily rely on the mutual help in group settings. Individuals with social anxiety, however, may be reluctant to attend group therapy or AA meetings or may avoid meaningful participation should they make the effort to attend. Other activities that are integral to participation in AA, such as sharing one’s story (i.e., public speaking), obtaining a sponsor, and becoming a sponsor (i.e., initiating social contact) also can be impaired among socially anxious alcoholics.
Research notes that changes in chemical levels such as serotonin can cause anxiety disorders and depression. In fact, 50% of people receiving treatment for alcohol use disorder also live with an anxiety disorder. Factors such as dehydration, lack of quality sleep, and alcohol withdrawal symptoms can further contribute to prolonged anxiety.
Talk to your doctor about medications, therapy, and support groups that can help you manage your alcohol consumption. If you have anxiety and are using alcohol to cope, it’s important that you seek support from your doctor or mental health professional. It’s never too late (or too soon) to reach alcohol serotonin anxiety out for help if you are trying to cope with a mental health condition or substance use disorder. In some cases, a person who drinks alcohol to relieve feelings of anxiety might end up drinking more because they expect alcohol to provide a certain amount of relief from their anxiety symptoms. Experiencing anxiety the day after drinking, commonly known as a “hangover anxiety” or “hangxiety,” is a common occurrence for many individuals.
