Hand shaking can eat fruit, and the causes of hand shaking can be found out: First, Parkinson's disease, the most typical manifestation is that the thumb and forefinger move together three or four times per second, which is professionally called rubbing pills. With the extension of the course of the disease, symptoms such as decreased performance, stiff limbs, decreased activity and unstable walking may appear.

Second, idiopathic tremor, contrary to Parkinson's disease, if the tremor is obvious during physical activity, and it is relieved or disappeared during rest, and there are similar patients in the family, and a small amount of drinking can alleviate the tremor, you should first suspect idiopathic tremor.

Third, hyperthyroidism, if hand shaking is accompanied by symptoms such as emaciation, hyperhidrosis, exophthalmos, and rapid heartbeat, you should go to the hospital in time for serum thyroxine and thyroid B-ultrasound examination, because hyperthyroidism is also a common cause of limb jitter.

Fourth, cerebellar lesions, this kind of patients can appear intentional tremor, intentional tremor means that the closer the patient is to the target or object, the more obvious the jitter, and patients with cerebellar lesions can also appear ataxia such as nystagmus, speech changes, and unstable standing and walking.
