What is the cause of hand shaking?

Mr. Li, a 40-year-old civil servant, had a hand shake a month ago and could not control it. At that time, he thought it was caused by work pressure and mental stress, so he didn't care. During this period, he and his colleagues had a few drinks. After drinking, the hand shaking would be obviously relieved, but it didn't last long. After repeated months, his trembling hands still didn't ease, and he was a little scared. He came to see me at the clinic today and asked me if he had Parkinson's disease.

Before talking about Mr. Li's illness, let's talk about the common causes of hand shaking. Hand tremor belongs to medical tremor, which is an involuntary, rhythmic and vibrating movement of a certain part of the body. It is also a very common phenomenon. Almost everyone has experienced it, but most of them appear when they are nervous or extremely angry. It belongs to physiological tremor, which will return to normal in the later stage and will not have any influence on daily life. But if the tremor caused by the disease is not so easy to recover, it may last for a long time, or it may get worse all the time, and there will be tremor in many parts of the body, or other symptoms, so which diseases will cause tremor?

Parkinson's disease

First of all, Parkinson's disease is the most widely known disease. Every April 1 1 is World Parkinson's Day. On this day, many hospitals in China will also carry out some free clinic activities to popularize the knowledge of Parkinson's disease. Parkinson's disease, also known as Parkinson's disease, is a common neurodegenerative disease in middle-aged and elderly people. The prevalence rate of people over 65 years old in China is 1.7%, and it is estimated that there will be more than 654.38+million new patients every year. The number of patients with Parkinson's disease in China is about 2 million. The etiology of Parkinson's disease is not completely clear, and now it can only be said that it is related to age, environment, heredity, defects or abnormal functions of certain substances in the body. At present, it is clear that the motor symptoms of Parkinson's disease are caused by the lack of dopamine neurotransmitters in the brain. Therefore, the drugs for treating Parkinson's disease are also around dopamine, a neurotransmitter.

Characteristics of Parkinson's disease:

1. Most of them are over 60 years old.

2. Unilateral onset and gradual progress

3. Slow exercise

4. It may be accompanied by static tremor, which will be relieved when voluntary movement (that is, it will be relieved when it is still and active).

5. It may be accompanied by muscle stiffness or unstable posture.

If the above performance occurs, we should be alert to Parkinson's disease.

essential tremor (ET)

Essential tremor is the most common dyskinesia disease with hereditary tendency. It can occur at any age and the disease progresses slowly. More than 60% patients have family history. Postural or exercise tremor is the only clinical symptom, which mostly occurs in the hands and forearms, but also involves the head and neck, lower limbs, trunk and other parts. Symptoms can be temporarily relieved after a small amount of drinking. The cause of this disease is still unknown. Many diseases have hand tremors in the early stage, so it is difficult to identify them.

Characteristics of essential tremor:

1. Both parties appear at the same time

2. Posture and/or motion tremor

3. There is no sign of other nervous system.

4. Slow progress (stable for several years or decades)

The incidence of essential tremor is high, but there is no specific examination item. Clinically, the diagnosis can only be made according to the medical history, symptoms and auxiliary examination, so as to exclude other diseases, so it is necessary to go to the clinic of a professional doctor.

hyperthyroidism

Everyone has heard of hyperthyroidism. At present, the incidence rate is very high, reaching 3 1/65438+ ten thousand. When it comes to hyperthyroidism, it will be associated with symptoms such as big temper and eye swelling, which are also two common manifestations of hyperthyroidism. It is called hyperthyroidism because the thyroid gland synthesizes and releases too much thyroid hormone for various reasons, which leads to hypermetabolism and sympathetic nerve excitement, causing palpitation, sweating, eating, defecation, weight loss and other symptoms. Another common symptom that is easily overlooked by everyone is hand shaking. Hyperthyroidism patients are often excited because of abnormal hormone secretion, which is very prone to mental allergies. At this time, they are also prone to symptoms of hand shaking. When the patient is emotional, when the patient's hand reaches forward, there is often a tremor. This is also the reason why hyperthyroidism patients often have hand tremors.

Characteristics of hyperthyroidism:

1. Common palpitations, hyperhidrosis, increased frequency of eating and weight loss, insomnia and irritability.

2. Most patients often have exophthalmos, eyelid edema and decreased vision at the same time.

3. Hand tremors are bilateral.

4. Abnormal thyroid hormone examination

If you have the above symptoms or test results, please go to the endocrinology department of the hospital as soon as possible.

cerebrovascular disease

When it comes to cerebrovascular diseases, people first think of hemiplegia, but cerebrovascular diseases are a general term, including cerebral hemorrhage, cerebral infarction, subarachnoid hemorrhage, intracranial venous thrombosis and some hereditary cerebrovascular diseases. According to the location and degree of injury, their symptoms are also different. No matter what kind of cerebrovascular disease, when it is damaged in the extrapyramidal system of the brain, it may cause symptoms similar to Parkinson's disease, such as tremor and limb stiffness.

Characteristics of tremor caused by cerebrovascular diseases;

1. Recent history of cerebrovascular disease.

2. Tremor is accompanied by other neurological deficit symptoms (hemiplegia, language disorder, sensory disorder, dysphagia, cognitive disorder, etc.). )

3. Common Parkinson's syndrome of lower limbs (slow pace, instability, difficulty in starting, etc.). )

4. A few patients involve both upper limbs and have postural tremor (tremor occurs when both hands actively maintain a certain posture), but static tremor is rare.

When symptoms similar to Parkinson's disease appear after cerebrovascular disease, the possibility of vascular Parkinson's syndrome should be considered.

These are some common causes of hand shaking. In addition, there are many other reasons, such as: drug-induced tremor (common drugs are phenothiazine, styrene butadiene, reserpine, metoclopramide, flunarizine, deanxit, etc. The symptoms can be obviously alleviated or disappeared after several weeks to several months of drug withdrawal); Poisoning (carbon monoxide and manganese poisoning are the most common); After infection (viral encephalitis, Parkinson's syndrome symptoms are generally mild and short-lived); Traumatic (concussion); Multiple system atrophy (a neurodegenerative disease, which may be accompanied by Parkinson's disease, tremor is often not obvious, and it is common to stand unsteadily, postural hypotension, dizziness, dysuria, sexual dysfunction, bradykinesia, etc. ); Alcohol tremor is the most common symptom of alcohol withdrawal syndrome, accompanied by irritability and gastrointestinal symptoms, especially nausea and vomiting. These symptoms often begin in the morning after drinking for several days and suddenly banning alcohol. Restoring drinking can quickly relieve symptoms, and symptoms will recur and worsen after abstinence again. Systemic tremor is the most obvious feature of this disease. These diseases are rare at ordinary times, but they all need to be considered when diagnosing tremor.

Finally, let's take a look at Mr. Li's condition. Do we have any clues? His hands trembled on both sides. He is young and has no other medical history. He can get over it after drinking. After some necessary examinations, Mr. Li is most likely to have primary tremor, but it is necessary to further observe the condition and observe the changes of the condition after taking the medicine before making a diagnosis.

Be sure to remember to go to the hospital as soon as possible if the related symptoms persist, because time is the most precious in the face of illness.
