Anxiety manifestations are clinically divided into the following three categories: 1. Psychogenic tension and anxiety: manifested as excessive worry or inexplicable tension in patients, who are overly nervous and worried about current events or future events; 2. Neurogenic tension: patients mainly manifest motor restlessness, appearing such behaviors as rubbing their hands and feet, stumbling and wandering; 3. Autonomic dysfunction: such as dry mouth, rapid heartbeat, rapid breathing, sweating, shivering dizziness, vertigo, and migraine. The above conditions are manifestations of anxiety autonomic dysfunction.
