New research conducted on mice suggests repeated heavy drinking causes synaptic dysfunctions that lead to anxiety.
- The study was conducted on mice, who were given the equivalent of five drinks daily for 10 days.
- Images of the alcoholic mice brains showed synaptic dysfunctions related to microglia (immune cells in the brain).
- The results suggest that regulating TNF, a signaling protein related to systemic inflammation, may someday play a part in treating alcohol addiction.

The role of TNF in anxiety<p>But the new study revealed an interesting finding about TNF. To find out how TNF interacts with anxiety, the researchers gave to the alcoholic mice a drug called <a href="https://www.drugs.com/mtm/pomalidomide.html" target="_blank">pomalidomide</a>, which blocks the production of TNF. After, the mice showed improved synaptic functioning and less anxiety-like behaviors.</p><p style="margin-left: 20px;">"This study suggests that regulating the levels of TNF might eventually be useful when treating alcohol addiction," Relvas told Inverse.</p>

After all, even if science can fix the anxiety aspect of alcoholism, heavy drinking still exacts heavy tolls on other parts of the body and brain.</p><p>For now, it's probably best to keep your drinking within moderate levels: <a href="https://health.gov/our-work/food-nutrition/2015-2020-dietary-guidelines/guidelines/appendix-9/" target="_blank">Most</a> <a href="https://www.nytimes.com/2018/08/27/health/alcohol-drinking-health.html" target="_blank">research</a> suggests that having one to two drinks per day yields no significant negative health consequences.</p>
