Question

Quizplus · Accepted Answer

The physiological measure that consistently distinguishes individuals with GAD from nonanxious normal subjects is increased muscle tension. This is often seen as the individual experiencing restlessness and a sense of being on edge. Increased heart rate and decreased skin conductance levels can also be seen in anxiety disorders, but they are not consistently present. Decreased EEG beta activity may be seen in some anxiety disorders, but it is not specific to GAD.
