In generalized anxiety disorder, anxiety is pervasive and widespread but not limited to or even substantially predominating in any specific environmental circumstances (i.e., it is free-floating). The predominant symptoms, like complaints of ongoing anxiety, shaking, muscle tension, perspiration, light-headedness, palpitations, dizziness, and epigastric discomfort are frequent. Along with many other anxieties and dreads, the patient or a family member frequently expresses fears that they or another person may fall ill or have an accident soon.
