Your friend's hand tremors are medically called tremors. It is just a symptom, which means that part or all of the body shows involuntary rhythmic tremor, which can be divided into static tremor, exercise tremor, postural tremor, rebound tremor and vibration tremor clinically. Resting tremor refers to limb tremor when muscles relax and disappear during sleep, which is more rhythmic. Parkinson's syndrome falls into this category. Exercise tremor does not appear at rest, but only during exercise. It is characterized by no rhythm and large amplitude, and often occurs due to emotional excitement and mental stimulation. This is the result of antagonistic muscle coordination disorder. It is often the reaction of cerebellar lesions, such as cerebellar tumors, commissural arm lesions and cerebrovascular sclerosis. Postural tremor is also called intentional tremor. This kind of tremor actually belongs to sports tremor, that is, it only appears when the body is in a certain posture (such as lying or sitting) or engaged in a certain purpose of sports or maintaining a certain posture, and disappears when it is still. Although tremor is manifested as shaking hands, its root is mostly in the brain, and the area of the brain involved in motor coordination function is damaged by some diseases. Clinical causes include Parkinson's syndrome, hepatolenticular degeneration, hepatic encephalopathy, cerebellar and brainstem lesions, cerebral arteriosclerosis, cerebral ischemia, drug poisoning, dementia and so on. For example, in the TV series, Jia Rong's hand tremor attack is probably due to his old-age hypertension, arteriosclerosis and sudden mental stimulation from the time, place, age and inducing factors.
Generally speaking, the symptoms of hand tremor mostly appear in the elderly. Your friend is only over 40 years old. You should consult a neurologist, endocrinologist and metabologist for proper examination, so as to make clear the cause and correct treatment.
