The full name of anxiety disorder is generalized anxiety disorder, which mainly manifests as anxiety. The subtypes of anxiety disorders are acute and chronic, and acute anxiety is mostly a sudden anxiety condition caused by unexpected situations that produce a sense of severe suffocation, a sense of mental loss of control, etc. There are usually no precursors, and it occurs with the event. Chronic anxiety disorder and moderate to mild anxiety disorder also do not have 10 clear precursors, but commonly have the following two types of precursors: 1. Mental anxiety: If there is excessive worry about small everyday things, such as physical health, what will happen tomorrow, and accompanied by symptoms of dizziness, regurgitation and other discomfort. There may also be fear of scenes related to real life, sensitivity and alertness to the external environment, and tense muscles, which may be a precursor of anxiety disorder. 2. Some people may also experience panic attacks and even morbid physiological reactions such as frequent urination and urinary urgency, which may also be a precursor to anxiety disorders. Regardless of which precursor behaviors appear or what kind of period the anxiety disorder is in, patients should pay attention to it and seek timely psychological guidance, health education or cognitive behavioral therapy. In severe cases, patients should take medications as prescribed by their doctors to help treat the disease, improve the symptoms and control the development of the disease to avoid the development of depression or other co-occurring mental illnesses or physical discomfort as time progresses or the disease progresses.
