Irritability and anxiety are mainly seen in patients with anxiety disorders, which mainly manifest mental anxiety, excessive worry, and concern about the unpredictability of the future, and sometimes this intense worry leads to feelings of panic, fear, and imminent danger. In addition to anxiety and irritability, patients also experience physical discomfort, such as motor restlessness, muscle tension, and panic, palpitations, chest tightness, shortness of breath, muscle tremors, dry mouth, frequent urination, or physical discomfort. Therefore, the patient’s arousal level is significantly increased, triggering anger, startle response or excessive alertness to small things that are sensitive to external stimuli. In this case, the clinic can apply anti-anxiety drugs and carry out systematic standardized treatment, such as the application of benzodiazepine anti-anxiety drugs, which can improve the above symptoms, and can also improve the patient’s anxiety, irritability and physical discomfort experience by means of behavioral training, such as relaxation training.
