Anxiety Disorders

Overview and Facts

When times become stressful, anxiety is a natural reaction. But when worry, fear and anxiety becomes excessive and irrational, it can interfere with an individual’s ability to function in a normal manner. This is when a person likely has an anxiety disorder.

There are five major types of anxiety disorders:

Generalized Anxiety Disorder (GAD): Generalized Anxiety Disorder is characterized by chronic anxiety and excessive, unrealistic worrying and tension, even when nothing provokes it.

Obsessive-Compulsive Disorder (OCD): Obsessive-Compulsive Disorder is an anxiety disorder in which people have recurrent thoughts or fears that overwhelm them to the point where they have the urgent need to perform routines or rituals.

Panic disorder: Panic disorder is where the individual experiences anxiety and panic attacks, which are sudden attacks of terror that often produce a fear of impending doom or loss of control.

Post-Traumatic Stress Disorder (PTSD): This disorder is a type of stress anxiety that can result from an individual experiencing a terrifying event. The individual often ‘re-lives’ the event through flashbacks or nightmares.

Social Anxiety Disorder: Social anxiety disorder is when an individual experiences overwhelming anxiety symptoms in everyday social settings.

Causes and Diagnosis

The cause of anxiety disorder is not exact, but researchers believe a variety of biological, psychological and social factors play a role. Factors such as:

Life experiences – Exposure to abuse, violence (especially in a military setting), and poverty can cause anxiety

Heredity – It is clear that anxiety disorders have a genetic factor and thus run in families

Personality – Those who have low self-esteem and social skills may susceptible to having anxiety disorders

Brain chemistry – Abnormal levels of chemicals in the brain can cause anxiety

Stress – Anxiety stress can develop from stress related to work, school, finances, trauma, relationships and more

There are unfortunately no laboratory tests that can diagnose anxiety disorders. A doctor will instead evaluate your mental by performing a physical exam and asking questions about your medical history, the way you are feeling, your symptoms and more. The doctor may also perform tests that don’t necessarily diagnose anxiety, but the test results can determine if another illness is causing the anxiety symptoms. A diagnosis is typically based on the intensity of the symptoms – if they are present for at least six months and are interfering with normal daily activities, it is likely it is an anxiety disorder.

Tests and Treatment Options

If your doctor has diagnosed you with an anxiety disorder, the next step is treating the anxiety disorder. You will first see a mental health professional who is specially trained in mental disorders. Together, you will be able to decide which anxiety treatments are right for you.
Treatment for anxiety disorders often includes both medication and behavioral therapy. Although many people cannot be cured, these treatments provide substantial relief from symptoms.

Medication: Drugs may be particularly helpful to those suffering from anxiety disorders that have interfered with daily functioning. Drugs called benzodiazepines are commonly used to decrease physical symptoms of anxiety disorders. Antidepressants may also be used with anxiety and depression are working in tandem – they are more appropriately used for long-term treatment of anxiety disorders.

Cognitive-behavioral therapy: This type of therapy helps those suffering from anxiety disorders to recognize their thought patterns and behaviors and learn how to change them. This recognition of one’s behavior helps to limit unrealistic thinking and distorted views
People with anxiety disorders typically benefit from joining a support group. By sharing their problems and achievements with others, it can help them to better identify how to change.

Stress management and meditation may also be of help to those suffering from anxiety disorders.
