Anxiety Disorders

(Chronic Free-Floating Anxiety)


Anxiety is a feeling of dread, tension, and unease. An anxiety disorder is when these feelings are intense or last for long periods of time. It may happen even if there is no specific cause. An anxiety disorder also causes problems in day to day life and relationships.

Anxiety may also occur with other conditions such as alcohol use disorder, drug abuse, or depression.

The doctor will ask about symptoms and past health. The doctor should also know about a person's medicines, drugs or supplements. A physical and exam will be done. The doctor will also ask questions about emotional health. It is important to be honest and open with the doctor. Many mental health disorders go untreated because people do not ask for help. An anxiety disorder may be suspected based on answers to these questions.

Other tests may be done if there could be another cause of anxiety. A referral may be made to a mental health professional. They can help to diagnose anxiety disorders or other mental health issues.


Anxiety disorders can be managed. Treatment can help to lower the effect on day to day life. The goal is to reduce stress and improve the reaction to it. A treatment plan may include a mix of the following:


The cause of anxiety disorders is not clear, so prevention is not known. To decrease the risk of an anxiety episode:

  • Be aware of situations, work, and people that cause you stress. Avoid them if you can.
  • Find a relaxation technique that works for you. Practice it often, not just when you have anxiety.
  • Grow and keep a strong social support system.
  • Express your emotions when they happen.
  • Challenge beliefs and thoughts that are not helpful to you.
  • Correct misperceptions. Ask others for their points of view.
  • Work with a therapist.
  • Avoid nicotine or other drugs. If you drink alcohol, drink only in moderation:
    • 1 drink or less per day for women
    • 2 drinks or less per day for men.
