Researchers at Texas A&M University found that substance use impairs cognitive flexibility by inhibiting specific neurons. Chronic cocaine or alcohol use alters the local inhibitory brain circuit, leading to decreased cognitive flexibility and increased risk of academic deficits and lower quality of life.
Researchers found that individuals with AUD displayed less impairment on fine motor and cognitive tasks when consuming a standard dose of alcohol, but showed significant impairment at a higher dose. This suggests that the physical effects of alcohol accumulation contribute to impaired performance beyond mere tolerance.

However, the study's authors caution that receiving genetic feedback is just the first step in behavior change, and connecting individuals to resources and support is crucial.
A recent study published in Calcified Tissue International found that heavy drinkers are at risk of muscle loss and frailty. The research, which analyzed data from the UK Biobank, suggests that consuming 10 units or more of alcohol per day can lead to lower muscle mass, even when adjusted for body size and other factors.

A new study of 200,000 patients found that those who smoke cigarettes and drink heavily are more likely to experience post-surgical complications. However, talking to a health coach about drinking-related risks before surgery can help patients cut their alcohol use in half and reduce the likelihood of surgical issues.
Researchers believe that changes in the brain's orexin system promote drug-seeking behavior and that existing insomnia treatments could reduce or eliminate cravings. Studies have shown that blocking this system reverses addiction in animals and reduces opioid cravings in human subjects.
A new study published in Molecular Psychiatry suggests that parental discord and divorce may be indicators of children's genetic risk for future alcohol misuse. Researchers found that exposure to parents' relationship discord or divorce is associated with increased risk of alcohol use disorder symptoms in adulthood.

The study included nearly 160,000 older U.S. adults and showed that better lifestyle habits can reduce mortality risk from various causes.
A new study suggests that spironolactone, a medication for heart problems and high blood pressure, may also be effective in reducing alcohol drinking. The research found that increasing doses of spironolactone decreased alcohol consumption in mice and rats, as well as in humans with excessive alcohol drinking.
Researchers found that mandatory breath testing among commercial drivers had no significant effect on the number of alcohol-related collisions between 2011 and 2020. The trend was similar to non-commercial drivers, suggesting that other measures may be needed to reduce drunk driving.
A new rodent study found that low doses of alcohol can trigger epigenomic and transcriptomic changes in the brain, creating an epigenetic pathway for addiction. The research suggests that even small quantities of alcohol can prime the brain for addiction, regardless of sex or quantity.
Research finds that a single dose of alcohol permanently changes brain structure and function, leading to increased risk of addiction. The study used fruit flies and mice models to show that ethanol-induced changes in mitochondrial dynamics and synapse balance contribute to long-lasting behavioral changes.
