What is Anxiety?
Generalized anxiety disorder (or GAD) is characterized by excessive, exaggerated anxiety and worry about everyday life events with no obvious reasons for worry. People with symptoms of generalized anxiety disorder tend to always expect disaster and can't stop worrying about health, money, family, work, or school. In people with GAD, the worry often is unrealistic or out of proportion for the situation. Daily life becomes a constant state of worry, fear, and dread. Eventually, the anxiety so dominates the person's thinking that it interferes with daily functioning, including work, school, social activities, and relationships.
Symptoms
GAD affects the way a person thinks, but the anxiety can lead to physical symptoms, as well. Symptoms of GAD can include:
- Excessive, ongoing worry and tension
- An unrealistic view of problems
- Restlessness or a feeling of being "edgy"
- Irritability
- Muscle tension
- Headaches
- Sweating
- Difficulty concentrating
- Nausea
- The need to go to the bathroom frequently
- Tiredness
- Trouble falling or staying asleep
- Trembling
- Being easily startled
Causes
The exact cause of GAD is not fully known, but a number of factors -- including genetics, brain chemistry and environmental stresses -- appear to contribute to its development.
- Genetics: Some research suggests that family history plays a part in increasing the likelihood that a person will develop GAD. This means that the tendency to develop GAD may be passed on in families.
- Brain chemistry: GAD has been associated with abnormal levels of certain neurotransmitters in the brain. Neurotransmitters are special chemical messengers that help move information from nerve cell to nerve cell. If the neurotransmitters are out of balance, messages cannot get through the brain properly. This can alter the way the brain reacts in certain situations, leading to anxiety.
- Environmental factors: Trauma and stressful events, such as abuse, the death of a loved one, divorce, changing jobs or schools, may lead to GAD. GAD also may become worse during periods of stress. The use of and withdrawal from addictive substances, including alcohol, caffeine, and nicotine, can also worsen anxiety.
Treatment
If no physical illness is found, you may be referred to a psychiatrist or psychologist, mental health cognitive-behavioral therapyprofessionals who are specially trained to diagnose and treat mental illnesses like GAD. Treatment for GAD most often includes a combination of medication and
- Medication: Drugs are available to treat GAD and may be especially helpful for people whose anxiety is interfering with daily functioning. The medications most often used to treat GAD in the short-term are from a class of drugs called benzodiazepines. These medications are sometimes referred to as "tranquilizers," because they leave you feeling calm and relaxed. They work by decreasing the physical symptoms of GAD, such as muscle tension and restlessness. Common benzodiazepines include Xanax, Librium, Valium and Ativan. Antidepressants, such as Paxil, Effexor, Prozac, Lexapro, and Zoloft, are also being used to treat GAD. These antidepressants may take a few weeks to start working but they're more appropriate for long-term treatment of GAD.
- Cognitive-behavioral therapy: People suffering from anxiety disorders often participate in this type of therapy, in which you learn to recognize and change thought patterns and behaviors that lead to anxious feelings. This type of therapy helps limit distorted thinking by looking at worries more realistically.
