Hand tremors in the early twenties may be caused by hyperthyroidism, which can also be seen in hepatomegaly. Hyperthyroidism can occur at any age. Patients mainly present with hand tremors at rest, and may also have fear of heat, excessive sweating, or palpitations. Some patients may present with diarrhea, or may have a thin body mass, and should be examined for thyroid ultrasound and thyroid function. If the diagnosis is clear, oral methimazole can be administered for treatment. If the patient has a fast heart rate, propranolol can also be given at the same time for treatment. Hepatomegaly is a rare disease in neurology, a degenerative disease of the nervous system, mainly caused by copper metabolism disorders. The lesion usually involves the liver or the nucleus accumbens, and some patients may develop a KF ring in the cornea of the eye. There may also be idiopathic tremor.
