Limb tremors can be Parkinson’s disease or other diseases, but they can be broadly distinguished by a combination of tremor form and other combined symptoms. There are several common limb tremors as follows, and the characteristics of each are briefly described for identification purposes. 1, Parkinson’s disease, also known as tremor paralysis. It is characterized by tremors of the hands, head, and feet, 4 to 6 times per second, often starting on one side of the hand, and then progressing to the ipsilateral foot, contralateral hand, and contralateral foot. However, the tremor is characteristic of occurring at rest and disappearing with movement. There is also a combination of rigidity, leadpipe like and cogwheel like hypertonia, and slow movement. Weakness and inflexibility of movement are the main manifestations in the early stage. 2. Hyperthyroidism Fine tremors in more than one upper limb with fast frequency. Also combined with palpitations, anxiety, insomnia, irritability, irritability, increased appetite but wasting. It is common in young women. Thyroid function tests can clarify the diagnosis. 3. Idiopathic tremor is mostly a fine tremor of the hands, which does not affect the activities in the early stage and has a tendency to worsen but is not obvious, and can take care of itself even in old age. It appears when agitated, and drinking can temporarily eliminate the symptoms. Patients often describe the tremor as trembling when they first take a drink, and the tremor disappears after a few drinks. Most often there is a family history. In addition, Parkinson’s syndrome, Parkinson’s overlap syndrome, neurosis, psychosis, motor neuron disease, hereditary ataxia, Huntington’s disease, multiple system atrophy, olivopontocerebellar microcephaly, and other brain degenerative diseases can show the manifestation of limb tremors, to confirm the diagnosis need to see a neurologist.
