Also called: Alcohol dependence
For most adults, moderate alcohol use is probably not harmful. However, about 18 million adult Americans have an alcohol use disorder (AUD). This means that their drinking causes distress and harm. It includes alcoholism and alcohol abuse.
Alcoholism, or alcohol dependence, is a disease that causes
- Craving – a strong need to drink
- Loss of control – not being able to stop drinking once you’ve started
- Physical dependence – withdrawal symptoms
- Tolerance – the need to drink more alcohol to feel the same effect
With alcohol abuse, you are not physically dependent, but you still have a serious problem. The drinking may cause problems at home, work, or school. It may cause you to put yourself in dangerous situations, or lead to legal or social problems.
Another common problem is binge drinking. It is drinking about five or more drinks in two hours for men. For women, it is about four or more drinks in two hours.
Too much alcohol is dangerous. Heavy drinking can increase the risk of certain cancers. It can cause damage to the liver, brain, and other organs. Drinking during pregnancy can harm your baby. Alcohol also increases the risk of death from car crashes, injuries, homicide, and suicide.
You may have an AUD if you can answer yes to two or more of these questions:
In the past year, have you
- Ended up drinking more or for a longer time than you had planned to?
- Wanted to cut down or stop drinking, or tried to, but couldn’t?
- Spent a lot of your time drinking, or recovering from drinking?
- Felt a strong need to drink?
- Found that drinking – or being sick from drinking – often interfered with your family life, job, or school?
- Kept drinking even though it was causing trouble with your family or friends?
- Given up or cut back on activities that you enjoyed just so you could drink?
- Gotten into dangerous situations while drinking or after drinking? Some examples are driving drunk and having unsafe sex.
- Kept drinking even though it was making you feel depressed or anxious? Or when it was adding to another health problem?
- Had to drink more and more to feel the effects of the alcohol?
- Had withdrawal symptoms when the alcohol was wearing off? They include trouble sleeping, shakiness, irritability, anxiety, depression, restlessness, nausea, and sweating. In severe cases, you could have a fever, seizures, or hallucinations.
If you have any of these symptoms, your drinking may already be a cause for concern. The more symptoms you have, the more serious the problem is. If you think you might have an AUD, see your health care provider for an evaluation. Your provider can help make a treatment plan, prescribe medicines, and if needed, give you treatment referrals.

Delirium is a condition that features rapidly changing mental states. It causes confusion and changes in behavior. Besides falling in and out of consciousness, there may be problems with
- Attention and awareness
- Thinking and memory
- Muscle control
- Sleeping and waking
Causes of delirium include medications, poisoning, serious illnesses or infections, and severe pain. It can also be part of some mental illnesses or dementia.
Delirium and dementia have similar symptoms, so it can be hard to tell them apart. They can also occur together. Delirium starts suddenly and can cause hallucinations. The symptoms may get better or worse, and can last for hours or weeks. On the other hand, dementia develops slowly and does not cause hallucinations. The symptoms are stable, and may last for months or years.
Delirium tremens is a serious type of alcohol withdrawal syndrome. It usually happens to people who stop drinking after years of alcohol abuse.
People with delirium often, though not always, make a full recovery after their underlying illness is treated.
