Diagnosis

Your doctor will ask about your symptoms and medical history. A psychiatric evaluation will be done. Your doctor may also perform a physical exam and diagnostic tests. Usually the results of these tests are normal. You may be referred to a psychotherapist for further evaluation.

Treatment

Effective treatment usually involves a combination of interventions, including:

Lifestyle Changes

Relaxation Techniques

  • Deep breathing
  • Meditation
  • Deep muscle relaxation
  • Massage
  • Engaging in pleasurable activities

Social Support

Psychotherapy

This therapy addresses thoughts, feelings, and behaviors that play a role in anxiety. It helps you work through traumas and conflicts.

Cognitive-behavioral therapy can help you identify negative thought patterns and behaviors. Over time, you can learn to retrain your thinking. This will help you choose better options in response to stress and anxiety.

Medication

For severe anxiety or anxiety disorder, medications may include:

  • Benzodiazepines
  • Buspirone
  • Tricyclic antidepressants
  • Selective serotonin reuptake inhibitors (SSRIs)

    Please Note: On March 22, 2004, the Food and Drug Administration (FDA) issued a Public Health Advisory that cautions physicians, patients, families, and caregivers of patients with depression to closely monitor both adults and children receiving certain antidepressant medications. The FDA is concerned about the possibility of worsening depression and/or the emergence of suicidal thoughts, especially among children and adolescents at the beginning of treatment, or when there is an increase or decrease in the dose. The medications of concern—mostly SSRIs (Selective Serotonin Re-uptake Inhibitors)—are: Prozac ( fluoxetine ), Zoloft ( sertraline ), Paxil ( paroxetine ), Luvox ( fluvoxamine ), Celexa ( citalopram ), Lexapro ( escitalopram ), Wellbutrin ( bupropion ), Effexor ( venlafaxine ), Serzone ( nefazodone ), and Remeron ( mirtazapine ). Of these, only Prozac (fluoxetine) is approved for use in children and adolescents for the treatment of major depressive disorder. Prozac (fluoxetine), Zoloft (sertraline), and Luvox (fluvoxamine) are approved for use in children and adolescents for the treatment of obsessive compulsive disorder.
