Overview of Alcohol Use Disorder

Area of Science:

• Neuroscience
• Psychiatry
• Public Health

Background:

• Alcohol consumption is widespread, with heavy drinking leading to significant adverse health and social outcomes.
• Alcohol use disorder (AUD) affects 11% of the U.S. population but is significantly undertreated, with less than 15% receiving any intervention.
• AUD has both genetic and environmental risk factors and impacts multiple neurotransmitter systems.

Purpose of the Study:

• To review the current landscape of alcohol use disorder (AUD) treatments.
• To highlight the underutilization of effective therapies for AUD.
• To discuss emerging and potential future treatments for AUD.

Main Methods:

• Literature review of existing research on AUD.
• Analysis of current treatment modalities, including psychosocial and pharmacological interventions.
• Exploration of novel therapeutic targets and drug candidates for AUD.

Main Results:

• Psychosocial treatments (CBT, MET) and approved medications (disulfiram, naltrexone, acamprosate) are effective but underprescribed.
• Off-label medications (topiramate, gabapentin) and emerging treatments (psychedelics, PDE4 inhibitors) show promise.
• AUD remains a highly stigmatized condition, hindering treatment access.

Conclusions:

• Effective treatments for AUD exist but are underutilized due to various factors, including stigma.
• Further research into precision therapeutics and novel drug candidates is needed.
• Reducing stigma and improving identification are critical for increasing AUD treatment accessibility and effectiveness.
