Some elderly people in life usually shake their hands, thinking that this is a normal phenomenon of old age, they do not pay attention to it, in fact, most of this phenomenon is a movement disorder disease. The elderly usually sit and do not feel how, but once they get up to get something, end a glass of water, or clip the dish when the hand shakes constantly, this may be a precursor to idiopathic tremor, idiopathic tremor elderly people should be extra vigilant. ”Hand trembling is not necessarily Parkinson’s disease, and Parkinson’s disease is the most important disease to distinguish is idiopathic tremor, postural or action tremor is the only manifestation of idiopathic tremor is slowly progressive or long-term non-progressive. Idiopathic tremor, also known as familial or benign idiopathic tremor, is a common clinical movement disorder that is inherited in an autosomal dominant fashion.” Idiopathic tremor is a disease characterized by postural and motor tremor, and is one of the most common diseases with tremor as a clinical manifestation, with an incidence of about 1%, no gender differences, and a “bimodal” onset in adolescence or early adulthood. Family history, most patients have mild symptoms. How to distinguish idiopathic tremor from other diseases “Essential tremor (ET) is the most common movement disorder, mainly postural and motor tremor of the hands, head and other parts of the body. Idiopathic tremor has a conflicting clinical nature; on the one hand, it is a mild, monosymptomatic disorder, and on the other hand, it is a common progressive disorder with significant clinical variability.” Differential diagnosis of idiopathic tremor: 1, Parkinson’s disease: elderly onset, tremor in one and both limbs, tremor is resting, with increased muscle tone, does not affect the head causing nodding or shaking, difficulty walking and turning, difficulty turning over, reduced stride length; typical movement initiation and conversion difficulties. 2, secondary Parkinson’s syndrome: there are clear etiologies to be found, such as traumatic brain injury, stroke, viral encephalitis, drugs, metal and carbon monoxide poisoning, etc. 1), drug or toxic: neuroleptics (phenothiazines and butylphenols), rifampin, gastroflucan, a-methyldopa, lithium, flunarizine, etc. can lead to reversible Parkinson’s syndrome, which occurs after treatment or several months after discontinuation of the drug; 2), vascular. History of multiple cerebral infarcts, pseudobulbar palsy, tendon reflex hyperactivity, pathological signs and neuroimaging may provide evidence. Pharmacological and surgical treatment of idiopathic tremor Most patients have mild symptoms and do not require treatment; initial onset can be treated with medication or moderate alcohol consumption as needed for the occasion. Regular medication, propranolol, paracetamol, is needed when symptoms persist; surgery can be considered when medication is not effective. ”Deep brain electrical stimulation (DBS), with an efficiency of 90%, began in 1990 with stereotactic surgery to implant electrodes into the ventral intermediate nucleus of the thalamus (VIM) to dispense electrical pulses to the VIM and regulate the electrical activity of the neural circuit to improve symptoms; the effect is similar to disruption, but reversible and adjustable, safer, and effective in 90% of patients reported in the literature.
