Generalized anxiety disorder (GAD), is characterized by unrealistic or excessive anxiety and worry about two or more life circumstances for at least six months.
A. Chronic worry is a prominent feature of GAD as opposed to the intermittent terror that characterizes panic disorder. Patients may report that they "can't stop worrying," which may revolve around life concerns relating to money, job, marriage, health, and safety of children.
B. Other features of GAD include insomnia, irritability, trembling, dry mouth, and a heightened startle reflex.
C. Symptoms of depression should be sought because 30-50% of patients with anxiety disorders will also have depression. Drugs and alcohol may contribute to anxiety disorders.
II. Medical disorders causing anxiety symptoms
B. Cardiac rhythm disturbances and mitral valve prolapse may cause anxiety symptoms.
C. Substance abuse or dependence with withdrawal symptoms may resemble anxiety.
D. Pharmacologic causes of anxiety include salicylate intoxication, NSAI Ds antihistamine intoxication/withdrawal, phenylpropanolamine pseudo-ephedrine, psychotropics (akathisia), stimulants, selective serotonin reuptake inhibitors. Caffeine, cocaine, amphetamines, theophylline, beta-agonists, over-the-counter decongestants, steroids, and marijuana can cause anxiety.
III. Laboratory evaluation of anxiety disorders
A. Chemistry profile (glucose, calcium, phosphate), TSH.
B. Special Tests. Urine drug screen, cortisol, serum catecholamine level.
A. Caffeinated beverages and excess alcohol should be avoided. Daily exercise and adequate sleep (with the use of medication if necessary) should be advised.
