General Information

DEFINITION--A vague, uncomfortable feeling of fear, dread or danger from an unknown source. For some it may be a one time episode; other persons become constantly anxious about everything. A certain amount of anxiety is normal and helps improve our performance and allows people to avoid dangerous situations. Several types of anxiety are recognized including acute situational anxiety (which is usually short-term), generalized anxiety disorder and adjustment disorder. (See also Panic Disorder, Post Traumatic Stress Disorder, Phobias, and Obsessive-Compulsive Disorder in Illness section). Generalized anxiety is defined as unrealistic or excessive anxiety for 6 months or longer. Anxiety is the most common mental health problem in the U.S.

BODY PARTS INVOLVED--Central nervous system; endocrine system.

SEX OR AGE MOST AFFECTED--Females more than males, and mainly in adults ages 20-45.

SIGNS & SYMPTOMS

• Feeling that something undesirable or harmful is about to happen (edginess and apprehension).
• Dry mouth; swallowing difficulty; hoarseness.
• Rapid breathing and heartbeat, palpitations.

CAUSES--Activation of the body's defense mechanisms for fight or flight. Excess adrenalin is discharged from the adrenal glands, and adrenalin breakdown products (catecholamines) eventually affect various parts of the body. Attempts to avoid the anxiety leads to more anxiety.
