Frequent panic attacks and hand tremors are caused by various factors, and organic related diseases should be excluded. For endocrine diseases, such as hyperthyroidism, panic attacks and hand tremors can occur frequently. For cerebrovascular diseases, such as hemorrhagic stroke, ischemic stroke, and hypertensive encephalopathy, patients often experience dizziness, headache, hemiparesis, aphasia, panic attacks, and hand tremors. In addition, for frequent panic attacks and hand tremors, it is necessary to pay attention to the presence of electrolyte disorders and to exclude disorders of acid-base balance. On the basis of excluding organic diseases, idiopathic tremor is often considered, which often occurs in the elderly, who have panic attacks and idiopathic tremor of the hands, and may develop Parkinson’s disease.
