What are anxiety disorders?
An anxiety disorder is a condition which causes you to feel
nervous, worried, or jittery almost daily or many times during a
week. All of us have times when we worry or feel nervous and upset
about things. This is normal.
An anxiety disorder is not just nervousness, fretting, or
"butterflies" in the stomach. Anxiety disorders usually include
outright fear, panic, and terror. The fright and terror often keep
you from doing daily activities.
Are there different kinds?
There are several kinds of anxiety disorders. Some people have
more than one kind at a time. The main kinds are:
- Anxiety Disorder Due to a General Medical Condition. Troubles
with anxiety and nervousness can be caused by physical
problems. Medical conditions such as hormone imbalances,
breathing problems, and heart problems can cause anxiety.
- Generalized Anxiety Disorder (GAD). GAD is anxiety or worry
that causes you problems in many areas every day or nearly
every day for 6 months or more. Worries often cause physical
symptoms such as headaches, back pain, and intestinal or
stomach upset.
- Panic Disorder. When panic attacks occur without warning, or
you have repeated unexpected attacks, it is called panic
disorder. These attacks can happen many times every day or
every week. You might worry about having these attacks
throughout the day. It can interfere with your work and
personal life.
- Phobias. Having a phobia means that you feel dread or panic
when you face a certain activity, event, or object. Some
people fear dogs, heights, or snakes. People with agoraphobia
avoid going places or doing things because they fear they will
have no way to escape or will panic and have no help. Social
phobia is fear of events such as parties, presentations, and
meetings.
- Posttraumatic Stress Disorder (PTSD). PTSD begins after you
witness or are involved in a very stressful event. The event
usually involves the threat of severe injury or death. PTSD is
when symptoms continue for months or years after the event is
over.
- Substance-Induced Anxiety Disorder. Drugs such as alcohol,
cocaine, sedatives, and amphetamines can make you feel
nervous, worried, or jittery. Stopping drug use for a few
weeks usually reduces fears and worry.
How do they occur?
Many anxiety disorders begin in late childhood through the young
adult years. Anxiety disorders caused by medical or substance
abuse problems can start at any age. Some problems come on slowly
over weeks or months. Anxiety can also begin suddenly. A stressful
event can also create anxiety.
The exact cause of anxiety is not known. The brain is made up of
billions of neurons (cells) that communicate with each other. This
affects other parts of the body. Neurotransmitters are chemical
substances in the brain. The kinds and amounts of these substances
control how neurons communicate. Too much or too little of these
neurotransmitters may lead to anxiety.
Anxiety problems tend to run in families. Stressful life events
and situations also play a major part. Anxiety is more common if
you have few friends, family, and activities. Poor diet and lack
of daily exercise may also make anxiety disorders more likely.
Many people have both anxiety and depression. You may need
treatment for both problems.
How are they diagnosed?
Your healthcare provider or a mental health therapist will ask
about your symptoms and any drug or alcohol use. You have lab
tests to rule out medical problems such as hormone imbalances and
heart problems.
How are they treated?
Anxiety may be treated with psychotherapy, medicine, or both. The
best treatment for you depends on which type of anxiety disorder
you have.
How long will the effects last?
Some anxiety disorders last for a short time. Others may happen
over and over throughout life.
When should I seek help?
Do not try to overcome anxiety all by yourself. Seek professional
help if you believe that you or a loved one has the symptoms of an
anxiety disorder.
