Anxiety

Anxiety is an unpleasant state of tension, apprehension, or uneasiness (a fear that seems to arise from a unknown source). Disorders involving anxiety are the most common mental disturbances. The physical symptoms of severe anxiety are such as tachycardia,sweating, trembling, and palpitations and involve sympathetic activation. Episodes of mild anxiety are common life experiences and do not warrant treatment. However, the symptoms of severe, chronic, debilitating anxiety may be treated with anxiolytic and/or some form of behavioral therapy or psychotherapy. Because many of the anti-anxiety drugs also cause some sedation, the same drugs often function clinically as both anxiolytic and hypnotic. some have anticonvulsant activity as well.
