The current diagnostic criteria for generalized anxiety are mainly based on the ICD-10 criteria of the International Classification of Diseases. Specifically, the following aspects are considered: 1. To diagnose generalized anxiety patients must have obvious symptomatic manifestations of anxiety, nervousness, panic disorder, etc., and the symptoms have no clear object or fixed content, and belong to a floating anxiety state, where the anxiety will last for at least several weeks, usually more than 6 months along with social function impairment, and the patient will feel distressed; 2. The presence of nervousness, motor fidgeting, feeling nervousness, shaking, trembling, restlessness and other motor manifestations; 3. The presence of autonomic dysfunction symptoms, such as sweating, dizziness, palpitations, gastrointestinal discomfort, and even frequent and urgent urination; 4. In addition to the above symptoms, other diseases such as somatic diseases, thyroid diseases, heart diseases, and drug-induced anxiety problems should be ruled out. Only when the above four aspects are met can a diagnosis of generalized anxiety be made.
