There are several causes of essential tremor?

There are many causes of essential tremor, which are related to the following factors:

1. Genetic factors, people with a family history of heredity are more likely to get sick;

2. Environmental factors;

3. Long-term exposure to special drugs or chemical poisons;

4. Consumption of allergenic substances such as seafood;

5. After a cold or exertion, the hands are found to tremble involuntarily, and such cryptogenic factors can also lead to essential tremor.

Essential tremor is a hereditary disorder that is a disease of the extravertebral system with a high clinical incidence.

Many people experience finger tremor when holding a pen or chopsticks, or holding something with their hands during daily activities, which may be essential tremor. It is a type of postural tremor, which is caused by the limb maintaining a certain position. It tends to occur when you are concentrated, nervous, tired, or emotional.

Essential tremor can be treated with receptor blockers, such as propranolol, betalux, etc. If the disease is severe, botulinum toxin injections may be used. If essential tremor is suspected, an outpatient neurology clinic can be examined**.

Essential tremor, also known as essential tremor, is a common movement disorder in which tremor is the only manifestation. 1 3 patients have a positive family history of essential tremor and are inherited in an autosomal dominant manner. The pathogenesis and pathology of essential tremor are unknown, and three loci have been identified.

Essential tremor has insidious onset, slowly progresses, and can also resolve for a long time, and can occur at any age, but is more common in middle-aged and older adults over 40 years of age. Tremor is the only clinical symptom and is characterized by postural and action tremor, with no neurologic signs other than tremor.

Essential tremor has a conflicting clinical nature, on the one hand, it is a mild single symptomatic disease, and on the other hand, it is a common progressive disease with significant clinical variation. Essential tremor** is not clear.

There are many reasons for this.

Essential tremor is a chromosomal dominant genetic disorder, so the main cause is family history that is, genetic diseases, the most common is extrapyramidal disease, patients will manifest as normal or rhythmic involuntary movements of the head, face, jaw, tongue and lower limbs. Postural tremor and action tremor are clinical manifestations of this disease, often seen in one or both upper limbs and also involve the head, but the lower limbs are relatively rare, some patients will have tremor after drinking, and the tremor will be aggravated when emotional and nervous.

Essential tremor is caused by familial hereditary, genetic predisposition, aging, environmental factors, etc.

Suggestion: You should pay attention to doing some physical exercises as much as possible, such as tai chi and gymnastics. Eat more anti-arteriosclerosis foods, such as vegetables, fruits, celery, onions, etc., which have the effect of lowering blood pressure and anti-blood lipids.

High-fat, high-calorie, and high-sugar foods should be limited, especially fried foods should be eaten less. Essential tremor symptoms disappear after drinking some liquor, and worsen when you are nervous.

1. Familial hereditary: In long-term practice, medical scientists have found that essential tremor seems to have a tendency to gather in families, and the incidence of essential tremor patients and their relatives is higher than that of the normal population.

2. Environmental factors: Epidemiological findings have found that there are regional differences in the prevalence of essential tremor, so it is suspected that there may be some toxic substances in the environment that damage the neurons of the brain.

3. Genetic predisposition: Although essential tremor patients also have familial agglomeration, no clear pathogenic gene has been found in sporadic essential tremor patients, indicating that the first priority of essential tremor is multifactorial.

The exact condition of essential tremor is still unknown, but modern studies have found that genetics and environmental factors can cause essential tremor.

Essential tremor is caused by abnormal signaling in specific areas of the brain, including the cerebellum, thalamus, and brainstem. The exact cause of the disease is unknown, but about 30% to 50% of patients have a family history and are inherited in an autosomal dominant manner. However, some people who have no family history can also get the disease.

Predisposing factors. Studies have found that the level of dehydrocamel sppylline in patients with familial essential tremor is higher than that of the normal population, and dehydrosopherine is a neurotoxic substance that can cause tremor, which is higher in meat after long-term high-temperature cooking.

Heavy metals such as lead and smoking in the diet may also be associated with the onset of essential tremor.

Essential tremor is characterized by postural tremor, which is an involuntary but rhythmic tremor of the limb muscles. Tremors usually begin in the upper extremities and may also affect the head, legs, trunk, voice, and facial muscles.

Tremors usually begin with symmetry on both sides, starting with the hands and affecting the head and neck, voice, legs, or trunk.

Some patients begin with tremors in the head and neck, tongue, or voice, but rarely in the legs.

If the tremor is from the hands, start with the first.

Second, third, and fourth fingers start, so it is more difficult to detect early.

Tremor also affects the flexor and extensor muscles of the limb and is dominated by rhythmic up-and-down vibrating movements.

The frequency, amplitude, and limb distribution of tremors usually do not change significantly over several years, or they do change, and the progression is very slow.

Tremor is worse when people perform delicate movements, such as holding a drinking glass, tying a shoelace, or holding a needle and thread.

As the course of the disease increases, the frequency of tremor decreases and the amplitude increases, resulting in more severe functional impairment, and patients often have difficulty controlling tremor, thus affecting work and daily life.

Some patients can reduce tremor by ingesting a small amount of alcohol, but 42% to 75% of patients only maintain tremor for 2 4 hours after drinking, and the tremor worsens the next day.

1. Genetic predisposition:

Although the occurrence of essential tremor is related to aging and environmental toxins, not all older people or people who are exposed to the same environment, even those who also use large amounts of MPTP, develop essential tremor. Although there is also a familial agglomeration phenomenon in patients with essential tremor, no clear pathogenic gene has been found in sporadic patients with essential tremor so far, indicating that the ** of essential tremor is multifactorial.

2. Aging:

The disease mainly threatens the health of the elderly group, and China is constantly entering an aging society, which is also the main factor for the increasing incidence.

3. Familial hereditary:

In long-term practice, medical scientists have found that essential tremor seems to have a tendency to cluster in families, and the incidence of essential tremor in the family and relatives of patients with essential tremor is higher than that of the normal population.

Fourth, environmental factors:

The results of epidemiological investigation found that the occurrence of the disease is mainly due to the toxic substances that invade the neurons of the brain, with the development of society, environmental pollution has become more and more serious, carbon monoxide, gas poisoning has become very common, so we must pay more attention in ordinary times, so as not to cause essential tremor disease.

Essential tremor, also known as familial tremor, is autosomal dominant in about 60% of patients with a family history. Presence appears before the age of 65 to 70 years. Gulcher et al. found that the causative gene of this disease was located in 3q13, called Fet1, and Higgins et al. mapped the causative gene to 2p22 25, called ETM or ET2, and found that ETM may be a triplet repeat, which was confirmed in the other two families of familial essential tremor.

Sex chromosome abnormalities have also been reported in patients with this disease, and a small number of male patients have XXY and XYY. The diversity of clinical manifestations of familial ET suggests possible genetic heterogeneity and indicates that new loci may be discovered.

However, there are many sporadic cases of essential tremor, and the clinical manifestations and pattern of sporadic cases are basically the same as those of familial tremor, but the age of onset of familial tremor is earlier than that of sporadic cases. Therefore, familial tremor cannot be separated from essential tremor until the genes for essential tremor are known.

Essential tremor is the most common movement disorder and consists mainly of postural and motor tremor in the hands, head, and other parts of the body.

Guidance: Essential tremor** is not clear, it is recommended to go to the neurology department of a regular hospital in time for timely treatment**.

1. When the patient's body is in an environment containing toxic substances, it may cause damage to the patient's brain neurons, and due to long-term brain damage, it will also lead to the problem of essential tremor in the patient's body. Therefore, when there is an abnormal problem in the body, you should seek medical attention in time for an examination to determine whether it is caused by the poor environment in which you are in a bad environment.

2. If there are more people in the patient's family who suffer from the disease, the probability of the disease will be greatly improved. Although this cause cannot be avoided, patients should pay attention to maintaining an optimistic attitude to face the problem and avoid the influence of excessive anxiety and other negative emotions, so as to prevent the aggravation of physical problems.

3. Because of age, the body's organs and nerves will be weakened, which is easy to cause the disease in the body. Therefore, in daily life, you need to pay more attention to controlling your own diet and living habits, enhance your physical fitness, and carry out appropriate physical exercise, which can also promote the body's metabolism and enhance your own resistance and immunity, so as to effectively avoid physical problems.

Causes of essential tremor.

Causes of essential tremor 1. Environmental factors: Epidemiological findings have found that there are regional differences in the prevalence of essential tremor, so it is suspected that there may be some toxic substances in the environment that damage neurons in the brain.

Causes of essential tremor 2. Familial heritability: Medical scientists have found in long-term practice that essential tremor seems to have a tendency to gather in families, and the incidence of essential tremor in the family and relatives of patients with essential tremor is higher than that of the normal population.

Causes of essential tremor 3. Age: With the continuous increase of age, there are more and more people with essential tremor. Essential tremor is a disease of the brain that declines and is more common in people over the age of 50.
