Anxiety disorder is a neurological disorder in which anxiety is the predominant emotion. It is mainly divided into two types: panic disorder and generalized anxiety. The anxiety symptoms of anxiety disorders are primary. Any anxiety secondary to somatic diseases such as hypertension, coronary heart disease, hyperthyroidism, etc. should be diagnosed as anxiety syndrome. Other psychopathological states such as hallucinations, delusions, obsessive-compulsive disorder, hypochondria, depression, phobias and other concomitant anxiety should not be diagnosed as anxiety disorder. Panic disorder is a neurological disorder in which recurrent panic attacks are the main primary symptom. Such episodes are not limited to any specific context and are unpredictable in nature. Panic attacks as secondary symptoms are seen in many different psychiatric disorders, such as phobic neurosis and depression, and should be differentiated from certain physical disorders, such as epilepsy, heart attack, endocrine disorders, etc. Symptom criteria: 1. The diagnostic criteria of neurosis are met; 2. Panic attacks need to meet the following four items: (1) no obvious trigger for the attack, no relevant specific context, and the attack is unpredictable; (2) in the interval between attacks, there are no obvious symptoms except the fear of having another attack; (3) the attack shows intense fear, anxiety, and obvious autonomic symptoms, and there is often depersonalization, reality dissolution, near-death fear, or (4) The seizure starts suddenly, reaches its peak rapidly, and the patient is conscious during the seizure and can recall it afterwards. Severity Criteria: The patient is suffering because of unbearable and unrelieved pain. Course criteria: At least 3 panic attacks within 1 month, or anxiety secondary to fear of further attacks lasting 1 month after the first attack. Exclusion criteria: 1. Exclude panic attacks secondary to other psychiatric disorders such as phobias, depression, or somatoform disorders; 2. Exclude panic attacks secondary to somatic disorders such as epilepsy, heart attack, pheochromocytoma, hyperthyroidism, or spontaneous hypoglycemia. Generalized anxiety refers to a kind of anxiety disorder with a lack of clear objects and specific content, and tension and anxiety, with significant vegetative symptoms, muscle tension, and motor anxiety. Patients feel distressed because they can’t stand it and can’t get rid of it. Symptom criteria: 1. Meet the diagnostic criteria for neurosis; 2.
