What is involuntary hand tremor?

Involuntary hand tremors are a type of involuntary tremors. This is a relatively abnormal condition and we should pay attention to it once it occurs, because it may be a complication of certain diseases or a specific symptom of certain diseases. There may still be many people who do not know the specific disease that causes this condition. So what is the disease that causes involuntary hand tremors?

It is normal for the elderly to have hand tremors, but it is different for young people. Once this symptom appears, it indicates that a certain disease is about to occur. The most common ones are Parkinson's disease, Parkinson's syndrome, and essential tremor.

1. Parkinson's disease, also known as Parkinson's disease. It is a central nervous system disease caused by problems with the substantia nigra in the brain, resulting in involuntary shaking when the patient is at rest.

2. Parkinson's syndrome. There is another type of disease that is similar to Parkinson's disease and is caused by certain organic diseases, such as encephalitis, cerebrovascular and brain tumors, and craniocerebral trauma. In addition to hand tremors, patients also have various symptoms of the primary disease. For example, encephalitis may cause fever, cerebrovascular disease may cause limb paralysis, brain tumors may cause headaches and vomiting, and craniocerebral trauma may cause a history of trauma and impaired consciousness. For Parkinson's syndrome, as long as the primary disease is treated actively, the symptoms will be alleviated or disappear.

3. Essential tremor, also known as benign senile tremor, essential tremor or familial tremor. More than 60% of patients with this type of hand tremor have a family history, and it mostly occurs in middle-aged and elderly people. The main manifestation is hand tremors when performing actions, most of which can involve the upper limbs, mandible or head, but lower limb tremors rarely occur. The symptoms are generally mild in the early stage of the disease, and the condition gradually worsens and may affect daily life and activities, especially when doing various actions, the hands shake noticeably, such as cooking, holding chopsticks, drinking water, writing, unlocking, etc., the hands shake violently, or even cannot complete these actions at all. Some patients also experience changes in the tone and voice of their speech. Hand tremors will worsen when you are emotionally unstable, mentally stressed or tired, but drinking can temporarily relieve hand tremors. Neurological examination showed no abnormalities except hand tremors. Currently, the most common treatment is Western medicine, but it only treats the symptoms and not the root cause, and the disease is very likely to relapse.

4. Cervical spondylosis. Due to local nerve compression, symptoms such as numbness and trembling of the fingers often appear; hyperthyroidism in the elderly is generally manifested by increased appetite and weight loss, slightly bulging and bright eyes, but a few people only show trembling when the upper limbs are stretched out; trembling hands may also be a precursor to cerebral stroke.
