Welcome To Anxiety-Depression-Understanding..

Anxiety is a common, normal, and sometimes useful response that may improve performance for those facing life's challenges and dangers. But in some people, anxiety spins out of control. Anxiety disorders are characterized by either recurrent or persistent psychological and physical symptoms--such as intense fear, worry, dizziness, and palpitations--that interfere with normal functioning, continue in the absence of obvious external stresses, or are excessive responses to these stresses. Anxiety disorders may result from hyperactivity in certain areas of the brain or decreased activity of a neurotransmitter (a chemical messenger) called gamma-aminobutyric acid (GABA), which suppresses the action of neurons. Luckily, effective treatments are available, including psychotherapy, medication, and coping behaviors.

Generalized anxiety disorder

GAD affects 2 to 3 percent of the population. Although people with GAD know that the intensity, duration, or frequency of their anxiety and worry are well out of proportion to the actual likelihood or impact of the feared event, they still have difficulty controlling their emotions. Perpetual anxiety may impair concentration, memory, and decision-making ability; decrease attention span; and lead to a loss of confidence. Normal activities, such as working, socializing with friends, or maintaining intimate relationships, may become difficult or impossible.
