Anxiety is one of the common psychological symptoms and is often the main manifestation of anxiety disorders. Nervousness and excessive worry are the core symptoms of all anxiety disorders. Anxiety disorders can be treated with pharmacological and psychological treatments, with the most widely used behavioral and cognitive therapies, including biofeedback, being the most widely used clinical treatments. Medications and psychotherapy are an effective treatment for anxiety disorders such as anxiety disorders, phobias, social anxiety disorder and obsessive-compulsive disorder and hypochondria. 1, anxiety disorders Anxiety disorders (Anxiety disorders) is a common neurological disorder dominated by anxiety. The incidence rate is 2%, is a persistent anxiety, fear, tension and plant nervous activity disorders of brain dysfunction, often accompanied by motor anxiety and somatic discomfort. It occurs in young adults, and there is no significant difference in the incidence between men and women. Before the disease, most of the characters are timid and fearful, with low self-esteem and suspicion, thinking and hesitating to do things, and unable to adapt quickly to new things and new environments. The cause of the disease is mental factors, such as in a stressful environment can not adapt, encounter misfortune or difficult to undertake more complex and difficult work. As social competition becomes increasingly fierce and stress factors in life increase, anxiety reactions such as psychological maladjustment are bound to increase and should be taken seriously. There are two main types of panic disorder and generalized anxiety. 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. Common symptoms are intense tension, marked shortness of breath, feelings of near death, insanity, and cardiovascular system symptoms. Generalized anxiety: The symptoms of generalized anxiety are mainly nervousness and anxiety without clear objects and specific contents. Patients are anxious all day long, worrying about their work and health; worrying about the safety of their loved ones, and often accompanied by somatic discomfort, such as sweating, palpitations, chest pain, and a feeling of pins and needles all over the body. Patients feel pain because it is unbearable and cannot be relieved. Both of these patients often go to internal medicine or the emergency room, and are often mistaken for coronary heart attacks, respiratory disorders or other episodic diseases, repeatedly examined but no abnormal findings, so patients with the above symptoms should go to a psychiatric outpatient clinic for treatment. 2, phobia Phobia manifests itself as an excessive and unreasonable fear of external objects or situation-oriented neurosis. The patient knows that there is no need, but still fear, accompanied by significant anxiety and autonomic symptoms. The patient desperately avoids the feared object or situation, or endures it with awe. Place phobia: The object of fear is mainly certain specific environments, such as squares, closed rooms, dark places, crowded places, transportation (e.g., crowded ship cabins, train cars), heights, etc. Social phobia: Fear of objects mainly for social situations (such as eating or talking in public, parties, meetings, etc.) and interpersonal contact (such as contact with people in public, fear of eye contact with others, etc.); Specific phobias: Fear of objects are specific objects or situations not included in place fear and social phobia, such as animals (such as insects, rats, snakes, etc.), heights, darkness, lightning, blood, trauma, injections OCD is a neurological disorder characterized by obsessive-compulsive symptoms, characterized by the coexistence of conscious self-compulsions and counter-compulsions, causing the patient to feel anxious and distressed, and unable to get rid of them despite strong resistance. For example, repeated hand washing, door closing, repeated checking, repeated thinking, etc. If the disease is prolonged, the mental pain can be reduced by ritual actions, but social function is severely impaired. 4. Hypochondriasis is a neurological disorder characterized by a persistent fear or belief in the predominance of various somatic symptoms. Patients repeatedly seek medical attention for these symptoms, and various negative medical tests and doctors’ explanations are unable to dispel their doubts. Even if some kind of somatic disorder is sometimes present, it does not explain the nature or extent of the symptoms complained of, or their distress and predominant perceptions. It is often accompanied by anxiety or depression. The patient is often unaware of psychological factors, despite the fact that the onset and persistence of symptoms are closely related to unpleasant life events, difficulties, or conflicts. Anxiety disorders can be treated with some explanatory psychotherapy. Psychotherapy is extremely important to cure or relieve the patient’s anxiety symptoms. It can also be treated with some anti-anxiety medications, such as antidepressants (e.g., TCAs, SSRIs, SNRIs, MAOIs) and benzodiazepines. The treatment of patients with anxiety disorders begins with psychotherapy. The patient is treated with sympathetic care and consideration, assisted in eliminating the causes of the disease, has a correct understanding of the causes, solves specific difficulties, and provides a scientific explanation of the nature of the disease. The principles of psychotherapy for anxiety disorders are: 1. dealing with anxiety symptoms: such as relaxation, biofeedback; 2. fear/phobia: relaxation + exposure (overcoming avoidance behavior); 3., obsessive-compulsive disorder: exposure + reaction prevention; 4. changing inappropriate anxiety perceptions: anxiety is like climbing a mountain, there is a top even if the mountain is high, as long as you persist, you will go over the mountain, i.e. anxiety is self-limiting and will not last permanently and in great distress.
