When is hand tremor essential tremor?

Essential tremor is a common clinical movement disorder, tremor is the only manifestation, and occasionally reported with abnormal intonation and gait. Patients usually start with hand tremors, which progress to head tremors, leg tremors, and body tremors, and can also have unilateral upper extremities. With the course of the disease and age, the frequency gradually decreases and the amplitude gradually increases.

The written word may be distorted, but it will not appear to be too small. Another area that is commonly affected is the craniocervical muscles. The head, tongue, or vocal muscles can be involved and manifest as severe postural tremor and head tremor of the patient's hands, including vertical "nodding" movements and horizontal "shaking the head" movements.

Tremors of the soft palate and tongue can cause dysphonia. Hand tremors in these conditions are essential tremors.

People with essential tremor have involuntary shaking that starts in the hands and progresses upwards to eventually affect the head and face muscles, making speech difficult when it affects the laryngeal muscles.

People with essential tremor shake shake more severely when they are in a certain position or do something with their hands, such as when they thread a needle. Essential tremor usually begins with bilateral hand tremor and rarely begins with hand tremor in one hand. Usually there is only mild hand tremor at the beginning of the disease, which gradually worsens.

Tremors can occur in everyday life, but they become more severe with age, especially when mood changes, and eventually have a negative impact on daily life.

Essential tremor occurs after emotional tension, anger, anxiety, fatigue and hunger, holding chopsticks, holding cups, and writing. It is that the hand tremors occur under certain circumstances, and they usually do not shake or the shaking is not obvious.

Essential tremor can occur at any age, some have a family history, but there are no other organic lesions, there are no other abnormal symptoms except tremor, and hand tremor generally occurs or worsens in the above situations, especially postural or action tremor, that is, in a certain posture, or in the case of holding something, the closer you get to the object, the more delicate and obvious the shaking. The tremor is temporarily relieved after drinking, and it worsens on the second day of drinking, and is relieved by taking propranolol.

The sudden onset of hand tremors may be caused by hyperthyroidism, neurological disorders or acute cerebrovascular diseases. If you want to clarify the cause, you should go to the hospital in time to avoid delay and aggravation of the condition; At the same time, pay attention to rest and try to maintain emotional stability.

There are many causes of hand tremors, sometimes cerebrovascular lesions, nervous system lesions may occur in this condition, and there are also some shocking horses, so relevant examinations should be carried out to make a clear diagnosis before implementation**.

Postural tremor, which excludes other causes of tremor, is diagnostic of essential tremor, and the gold standard is autosomal testing.

The early stage of essential tremor usually begins with a tremor in one hand, and after a few years, it can affect the ipsilateral upper limbs, including both upper limbs and neck.

1. Typical essential tremor can be found in children, adolescents, middle-aged and elderly people.

There are two views on the peak age of onset. One view is that the age of onset is bimodal, i.e., in the age groups of 20 to 30 and 50 to 60 years; Another view is that essential tremor rarely occurs in adolescents and increases with age, with an average age of onset of 37 to 47 years.

2. The only symptom of essential tremor is tremor, which is occasionally reported to be accompanied by abnormal intonation and gait.

Patients usually start with the upper extremities and mainly affect the upper extremities, with a symmetrical onset in both upper extremities or unilateral upper extremities. Once the upper limbs are affected, it often progresses upward to the head, face, tongue, and jaw. Involvement of the trunk and bilateral lower extremities is rare, occurs only late in the course of the disease, and is less severe than the upper extremities.

With the course of the disease and age, the frequency gradually decreases and the amplitude gradually increases.

Typical symptoms are rhythmic abduction of the hand, adduction and flexion-extension tremor, and pronation and supination tremor (similar to Parkinson's disease) are rare. The written word may be distorted, but it will not appear to be too small. Another area that is commonly affected is the craniocervical muscles.

The head, tongue, or vocal muscles can be involved and manifest as severe postural tremor and head tremor of the patient's hands, including vertical "nodding" movements and horizontal "shaking the head" movements. Tremors of the soft palate and tongue can cause dysphonia.

3. Tremor affects activity 10 20 years after the onset of the disease, and the severity increases with age, so that the ability to complete fine activities is impaired, and reaches a peak in the 6th 10 years after the onset of the disease. Eighty-six percent of patients by the age of 60 to 70 years have an impact on social activities and living skills, including writing, drinking, eating, dressing, speech, and manipulation. The greater the tremor, the greater the impact on mobility.

There was no difference in the effect of tremor on gender.

4. Many factors can affect tremor, such as hunger, fatigue, emotional agitation, and temperature. As with most involuntary movements, essential tremor resolves during sleep, and there have been individual reports of tremors persisting in light sleep.

The response to ethanol (alcohol) in patients with essential tremor is characteristic. Many people can reduce tremor even if they consume only a small amount of ethanol (alcohol). 42% and 75% of patients had tremor reduced after drinking, but it was only temporary, generally lasting 2 4 hours, and the tremor worsened the next day.

There are few reports of a similar effect on other types of tremors with ethanol (alcohol), which works through the center.

5. Essential tremor can be accompanied by other movement disorders.

Patients with essential tremor have hand tremors, and patients will be nervous, excited, fatigued, hungry, concentrated, do fine work, hold cups, hold chopsticks, and have hand tremors.

Essential tremor is caused by nerve damage in modern medicine, because the instrument cannot detect the specific nerve damage, so it is more considered to be the central nervous system. Therefore, most of the drugs are drugs that control the heart rhythm and nerves. This kind of drug can only be relieved from the symptoms, and the effect is not long-lasting, and it is not recommended to take it for a long time.

It is more damaging to the body.

Regarding the problem of hand tremors, many people have this phenomenon. The most common of us is physiological tremor, that is, when the hand is raised forward, the hand will tremble slightly, and some people will be more obvious, and the hand can tremble when writing, and the written word will be a little bent. In addition, middle-aged and elderly people should pay attention to Parkinson's disease and Parkinsonism syndrome, they are often prone to hand tremors.

If you feel that hand tremor is affecting your work and life, it is recommended to go to the outpatient clinic of the neurology department for examination, because you can determine whether the cause of hand tremor is benign or pathological. Because many diseases can also cause hand tremors, such as hereditary diseases such as Wilson's disease degeneration that causes hand tremors, Parkinson's disease is prone to hand tremors. In addition, some stroke patients are also prone to hand tremors due to the sequelae of stroke.

In general, there are more benign hand tremors, that is, physiological tremor is more common, and senile tremor is more common in the elderly. On the **, it can be carried out with drugs such as propranolol, so as to reduce the frequency and amplitude of hand tremors, so that the quality of life is not affected.

Expert Q&A.

Hand shaking is what's going on.

Li Xuezhen, deputy chief physician.

Department of Neurosurgery, Beijing Tiantan Hospital, Capital Medical University.

The causes of hand tremors are related to psychological disorders and neurological and cerebral lesions.

Hand tremor, medically known as tremor, is characterized by involuntary rhythmic tremor of the hands.

Hand tremors can be divided into two types: physiological and pathological. Physiological hand tremors often occur in situations of nervousness, fear, emotional agitation, severe pain, and extreme fatigue, and once the causes of the tremors are removed, the tremors disappear.

Common diseases of pathological hand tremor include essential tremor, Parkinson's disease, Parkinson's syndrome, extravertebral diseases, cerebellar diseases, brain degenerative diseases, Wilson's disease, hepatic encephalopathy, drug poisoning, etc. According to the clinical manifestations, it is mainly divided into two types: resting hand tremor and motor hand tremor. Among them, resting hand tremor is the hand tremor that occurs when the muscles are completely relaxed, that is, in a quiet state.

This kind of hand tremor disappears during sleep, and the speed of hand tremor is 46 seconds and is relatively regular, typical of diseases such as Parkinson's syndrome. Motor hand tremor is a hand tremor that occurs only during exercise and is worse when the movement approaches the target. For example, when the doctor gives a patient a finger and nose test, he asks the patient to straighten his forearm; Then point your index finger at the tip of your nose; The closer the tip of the index finger is to the tip of the nose, the more pronounced the shaking of the hand becomes.

Motor hand tremors are irregular, the amplitude of shaking is large, and it is enhanced by emotion, and is common in lesions of cranial nerves and upper extremity nerves.

In life, some people may have shaking hands or unsteady holding of things, which is called "tremor" in medicine, and if the situation is not very serious, it often does not attract people's attention. Common** include: Essential tremor is the most common condition that causes hand tremors, mainly postural and motor tremors in the hands, head, and other parts of the body.

It is aggravated by concentration, nervousness, fatigue, and hunger, and most cases disappear temporarily after drinking alcohol and worsen the next day, but it should be noted that the disease cannot be treated by drinking. Parkinson's disease is another condition that often causes tremors. The disease is characterized by easy shaking when at rest, inflexible movements, stiffness of the limbs, and postural gait disturbances, while patients may be accompanied by symptoms such as depression, constipation, and sleep disturbances.

Hand tremors are not necessarily Parkinson's disease, and the most important condition to distinguish from Parkinson's disease is essential tremor, which is the only manifestation of essential tremor that progresses slowly or does not progress for a long time. Essential tremor, also known as familial or benign essential tremor, is a common clinical movement disorder and is inherited in an autosomal dominant manner.

Many diseases have symptoms of hand tremor, so we must be more vigilant about this, if you have begun to tremble, first of all, we must learn to judge the cause by ourselves, and carry out relevant mitigation measures, if you can not judge the disease, you must consult a doctor as soon as possible, do not ignore the "small symptom" of hand tremor.

Essential tremor.

It is true that there are symptoms of hand tremors, but it does not necessarily mean that hand tremors are associated with essential tremor. There are many factors that can trigger hand tremors, which can be considered to be a manifestation of torsional spasm or hand tremors caused by hyperthyroidism. In addition, overexertion of the hands may also cause symptoms of hand tremors.

Therefore, if the symptoms of hand tremor occur, you must consider it comprehensively, and go to a regular hospital to consult a professional doctor in time to find out the specifics.

There are many causes of hand tremors, such as hunger, low blood sugar, abnormal emotional agitation, Parkinson's, essential tremor, etc. If you have frequent hand tremors, it is recommended to go to the hospital in time to check and diagnose the cause of hand tremors, so as not to cause unnecessary trouble! Hope it helps, thank you!

If the hand tremors, sometimes it may be essential tremors, but sometimes it is certain, other tremors. This thing is possible.

Hand tremors are one of the most common and characteristic symptoms of Parkinson's disease, and many patients present for the disease because they notice hand tremors, which can be as high as 50% to 60%. But hand tremors aren't the only symptom of Parkinson's disease, and not all hand tremors are Parkinson's disease. This is because many diseases can cause hand tremors, including alcoholism or alcohol addiction.

The most common confusion with Parkinson's disease is essential tremor and liver disease, including metabolic disorders and thyroid dysfunction.

When you find that your hands are shaking, you should first check what factors cause hand tremors, and only after the investigation can you know whether it is Parkinson's disease, and don't think that hand tremors are Parkinson's disease.
