Information for Patients
What is anxiety?
Anxiety is a feeling of fear, dread, and uneasiness. It might cause you to sweat, feel restless and tense, and have a rapid heartbeat. It can be a normal reaction to stress. For example, you might feel anxious when faced with a difficult problem at work, before taking a test, or before making an important decision. It can help you to cope. The anxiety may give you a boost of energy or help you focus. But for people with anxiety disorders, the fear is not temporary and can be overwhelming.
What are anxiety disorders?
Anxiety disorders are conditions in which you have anxiety that does not go away and can get worse over time. The symptoms can interfere with daily activities such as job performance, schoolwork, and relationships.
What are the types of anxiety disorders?
There are several types of anxiety disorders, including
- Generalized anxiety disorder (GAD).People with GAD worry about ordinary issues such as health, money, work, and family. But their worries are excessive, and they have them almost every day for at least 6 months.
- Panic disorder. People with panic disorder have panic attacks. These are sudden, repeated periods of intense fear when there is no danger. The attacks come on quickly and can last several minutes or more.
- Phobias. People with phobias have an intense fear of something that poses little or no actual danger. Their fear may be about spiders, flying, going to crowded places, or being in social situations (known as social anxiety).
What causes anxiety disorders?
The cause of anxiety is unknown. Factors such as genetics, brain biology and chemistry, stress, and your environment may play a role.
Who is at risk for anxiety disorders?
The risk factors for the different types of anxiety disorders can vary. For example, GAD and phobias are more common in women, but social anxiety affects men and women equally. There are some general risk factors for all types of anxiety disorders, including
- Certain personality traits, such as being shy or withdrawn when you are in new situations or meeting new people
- Traumatic events in early childhood or adulthood
- Family history of anxiety or other mental disorders
- Some physical health conditions, such as thyroid problems or arrhythmia
What are the symptoms of anxiety disorders?
The different types of anxiety disorders can have different symptoms. But they all have a combination of
- Anxious thoughts or beliefs that are hard to control. They make you feel restless and tense and interfere with your daily life. They do not go away and can get worse over time.
- Physical symptoms, such as a pounding or rapid heartbeat, unexplained aches and pains, dizziness, and shortness of breath
- Changes in behavior, such as avoiding everyday activities you used to do
Using caffeine, other substances, and certain medicines can make your symptoms worse.
How are anxiety disorders diagnosed?
To diagnose anxiety disorders, your health care provider will ask about your symptoms and medical history. You may also have a physical exam and lab tests to make sure that a different health problem is not the cause of your symptoms.
If you don't have another health problem, you will get a psychological evaluation. Your provider may do it, or you may be referred to a mental health professional to get one.
What are the treatments for anxiety disorders?
The main treatments for anxiety disorders are psychotherapy (talk therapy), medicines, or both:
- Cognitive behavioral therapy (CBT) is a type of psychotherapy that is often used to treat anxiety disorders. CBT teaches you different ways of thinking and behaving. It can help you change how you react to the things that cause you to feel fear and anxiety. It may include exposure therapy. This focuses on having you confront your fears so that you will be able to do the things that you had been avoiding.
- Medicines to treat anxiety disorders include anti-anxiety medicines and certain antidepressants. Some types of medicines may work better for specific types of anxiety disorders. You should work closely with your health care provider to identify which medicine is best for you. You may need to try more than one medicine before you can find the right one.

Drug Use and Addiction
What are drugs?
Drugs are chemical substances that can change how your body and mind work. They include prescription medicines, over-the-counter medicines, alcohol, tobacco, and illegal drugs.
What is drug use?
Drug use, or misuse, includes
- Using illegal substances, such as
- Anabolic steroids
- Club drugs
- Misusing prescription medicines, including opioids. This means taking the medicines in a different way than the health care provider prescribed. This includes
- Taking a medicine that was prescribed for someone else
- Taking a larger dose than you are supposed to
- Using the medicine in a different way than you are supposed to. For example, instead of swallowing your tablets, you might crush and then snort or inject them.
- Using the medicine for another purpose, such as getting high
- Misusing over-the-counter medicines, including using them for another purpose and using them in a different way than you are supposed to
Drug use is dangerous. It can harm your brain and body, sometimes permanently. It can hurt the people around you, including friends, families, kids, and unborn babies. Drug use can also lead to addiction.
What is drug addiction?
Drug addiction is a chronic brain disease. It causes a person to take drugs repeatedly, despite the harm they cause. Repeated drug use can change the brain and lead to addiction.
The brain changes from addiction can be lasting, so drug addiction is considered a "relapsing" disease. This means that people in recovery are at risk for taking drugs again, even after years of not taking them.
Does everyone who takes drugs become addicted?
Not everyone who uses drugs becomes addicted. Everyone's bodies and brains are different, so their reactions to drugs can also be different. Some people may become addicted quickly, or it may happen over time. Other people never become addicted. Whether or not someone becomes addicted depends on many factors. They include genetic, environmental, and developmental factors.
Who is at risk for drug addiction?
Various risk factors can make you more likely to become addicted to drugs, including
- Your biology. People can react to drugs differently. Some people like the feeling the first time they try a drug and want more. Others hate how it feels and never try it again.
- Mental health problems. People who have untreated mental health problems, such as depression, anxiety, or attention deficit/hyperactivity disorder (ADHD) are more likely to become addicted. This can happen because drug use and mental health problems affect the same parts of the brain. Also, people with these problems may use drugs to try to feel better.
- Trouble at home. If your home is an unhappy place or was when you were growing up, you might be more likely to have a drug problem.
- Trouble in school, at work, or with making friends. You might use drugs to get your mind off these problems.
- Hanging around other people who use drugs. They might encourage you to try drugs.
- Starting drug use when you're young. When kids use drugs, it affects how their bodies and brains finish growing. This increases your chances of becoming addicted when you're an adult.
What are the signs that someone has a drug problem?
Signs that someone has a drug problem include
- Changing friends a lot
- Spending a lot of time alone
- Losing interest in favorite things
- Not taking care of themselves - for example, not taking showers, changing clothes, or brushing their teeth
- Being really tired and sad
- Eating more or eating less than usual
- Being very energetic, talking fast, or saying things that don't make sense
- Being in a bad mood
- Quickly changing between feeling bad and feeling good
- Sleeping at strange hours
- Missing important appointments
- Having problems at work or at school
- Having problems in personal or family relationships
What are the treatments for drug addiction?
Treatments for drug addiction include counseling, medicines, or both. Research shows that combining medicines with counseling gives most people the best chance of success.
The counseling may be individual, family, and/or group therapy. It can help you
- Understand why you got addicted
- See how drugs changed your behavior
- Learn how to deal with your problems so you won't go back to using drugs
- Learn to avoid places, people, and situations where you might be tempted to use drugs
Medicines can help with the symptoms of withdrawal. For addiction to certain drugs, there are also medicines that can help you re-establish normal brain function and decrease your cravings.
If you have a mental disorder along with an addiction, it is known as a dual diagnosis. It is important to treat both problems. This will increase your chance of success.
If you have a severe addiction, you may need hospital-based or residential treatment. Residential treatment programs combine housing and treatment services.
Can drug use and addiction be prevented?
Drug use and addiction are preventable. Prevention programs involving families, schools, communities, and the media may prevent or reduce drug use and addiction. These programs include education and outreach to help people understand the risks of drug use.
