What to know about alcohol abuse

People often view alcohol as a casual part of social life, but it can cause more harm than they realize. According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), almost 29 million people aged 12 and older in the United States struggled with alcohol use disorder (AUD) in 2022 alone. That’s over 10% of the population in that age group.¹

It’s easy to think you’re just “blowing off steam” with a few drinks, especially when stress and life’s pressures mount. But when alcohol use starts interfering with your mental clarity, relationships, or ability to manage responsibilities, it might be time to look deeper. And that’s where professional support from programs like ours at Promises Washburn House can make a meaningful difference.

What are alcohol abuse’s effects on the brain?

The effects of alcohol on the brain can be severe—and they can begin sooner than you might think. Alcohol can mess with the way your brain works, affecting how you process information, manage your mood, and stay in control of your movements. Over time, here’s what it can do to your brain:

Short-term impacts: Even after just one or two drinks, alcohol slows down brain function. This can lead to poor coordination, slurred speech, memory lapses, and difficulty making decisions.
Long-term damage: Prolonged alcohol abuse can lead to persistent cognitive impairments. Some people develop Wernicke-Korsakoff syndrome (WKS)—a type of brain damage caused by a deficiency in vitamin B1, often tied to long-term alcohol misuse.
Emotional impact: Drinking alcohol can mess with the part of your brain that handles emotions, making it harder to manage feelings over time. This can lead to more anxiety, depression, or even bouts of anger.
Changes in the brain: Long-term alcohol use can actually shrink areas of the brain that help with decision-making and self-control, according to MRI studies.²

Getting better together starts with understanding how alcohol has impacted your brain—and how treatment can help you heal those areas with time, support, and care.

What are other troubling side effects of alcohol addiction?

The brain isn’t the only part of your body affected by alcohol misuse. Alcohol abuse can affect nearly every major organ system. When someone drinks heavily over a long time, it can take a serious toll on their health:

Liver damage: The liver works hard to process alcohol, and over time, this can lead to issues like fatty liver or even cirrhosis.
Heart problems: Drinking too much can raise blood pressure, cause irregular heartbeats, and increase the risk of a stroke.
Digestive issues: Alcohol irritates the stomach lining, increasing risks for ulcers and pancreatitis.
Weakened immune system: Regular heavy drinking makes it harder for the body to fight off infections.

These physical effects, combined with the neurological and emotional toll, highlight why alcohol abuse is more than just a “bad habit”—it’s a condition that calls for real support and professional care.

Can addiction co-occur with other mental health issues?

Yes—and this happens more often than you might expect. Many people struggling with alcohol abuse are also dealing with anxiety, depression, other substance use disorders (SUDs), or trauma- and stress-related conditions like post-traumatic stress disorder (PTSD).³ When substance abuse and mental health conditions happen at the same time, they are called co-occurring disorders.

At Promises Washburn House, we provide dual diagnosis treatment to help you address both sides of the equation. Our therapists recognize how these conditions interact and create a care plan that reflects your full picture—not just your symptoms. There’s no such thing as a one-size-fits-all treatment for addiction, and we’ll never treat you like a number. Your journey is yours, but we’ll walk with you every step of the way.
