ANXIETY

Causes:

The exact cause of GAD is unknown, although it does appear to involve both psychological (mental) and physiological (physical) processes.

In particular it is believed, to be influenced by the activity of serotonin neurotransmitters (chemical messengers) in the Limbic System of the brain, an area, which processes information involved with emotions, memory, and behavior.

Symptoms:

• Motor tension
• Restlessness, feeling "edgy"
• Easily fatigued
• Shakiness
• Difficulty relaxing
• Back/neck pain
• Headache
• Irritability
• Sweating
• Dizziness
• Heart palpitation
• Frequent urination
• Shortness of breath

Diagnosis:

The diagnosis of GAD usually involves a thorough psychiatric examination.

A healthcare provider will interview the patient to identify symptoms, which correspond to GAD. Specifically, excessive anxiety and worry must occur more days than not and for at least six months. The anxiety is associated with three or more of the symptoms listed above. The result is an inability to work effectively or to enjoy social activities.
