How is essential tremor caused? How is essential tremor caused?

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

Essential**. 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 spine in patients with familial essential tremor is higher than that of the normal population, and dehydroscarpine is a neurotoxic substance that can cause tremor, which is found to be high in meat after prolonged high-temperature cooking.

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

The exact condition of essential tremor remains unclear. It may be the result of a combination of peripheral spindle afferents and central autonomic oscillators.

The only symptom of essential tremor is tremor, which has occasionally been reported to be accompanied by intonation and slight gait abnormalities. 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.

It is the most common movement disorder, mainly postural and motor tremor of the hands, head, and other parts of the body. Essential tremor has a conflicting clinical nature, on the one hand, it is a mild monosymptomatic disease, and on the other hand, it is a common progressive disease.

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

Help to adopt, thank you! It is divided into four types: physiological, pathological, psychological and primary.

1) Physiological: Some tremors do not occur in normal times, but only occur in certain situations (such as: stress, nervousness, anger), and even drinking coffee, tea, cola and other beverages are physiological tremors.

2) Psychological: hand tremors caused by mental illness, etc.

3) Primary (benign primary tremor): That is, we cannot find out exactly what causes the tremors, which may be caused by a specific constitution and have a certain genetic predisposition.

4) Pathological: refers to tremors caused by nervous system dysfunction, such as Parkinson's disease, or Parkinson's disease, as well as metabolic abnormalities (such as hypoglycemia or hyperthyroidism).

Suggestion: The general physiological can ignore it and avoid its predisposing factors. But pathological tremors, then ** is needed.

If essential tremor has been diagnosed and the symptoms are not severe, it can be temporarily dispensed with, it is indeed relatively serious and affects life, and it can be taken orally propranolol, or arolol or primidone and other drugs**. It is recommended to take the drug under the guidance of a neurologist**.

After the appearance of essential tremor, people will have hand tremors, and it will be aggravated when they are nervous and concentrated, and it will be reduced after drinking. Traditional Western medicine can't help everyone very well**essential tremor**, so everyone is very concerned about its latest**. Meridian intervention activation** can be said to be the latest in essential tremor**.

Patients with essential tremor should ensure that they eat 300 500 grams of cereals every day, such as rice, noodles, and grains. Nutrients such as carbohydrates, protein, dietary fiber, and B vitamins can be obtained from cereals, and the energy required by the body can be obtained. Eat about 300 grams of vegetables or melons a day, 1 2 medium-sized fruits.

Vitamins A, B, C, a variety of minerals and dietary fiber are obtained. It is recommended that you go to a local regular tertiary hospital for examination, and the doctor will treat the symptoms according to your specific situation, so that the effect will be better and the fee will be more fair and reasonable. The above is a suggestion for this question, I hope it will be helpful to you, I wish you good health!

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

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. The tremor of this disease, which worsens with concentration, nervousness, fatigue, and hunger, and in most cases disappears temporarily after drinking alcohol and worsens the next day, which is also a clinical feature of essential tremor.

Essential tremor** is unclear and can be confused with tremor produced by other disorders.

The exact physiology of the disease remains unclear. It may be the result of the combined action of peripheral muscle spindle afferents and central autonomic oscillators.

Causes: Aging age (15%)

This is the main reason why essential tremor is preferred in older people. In old age, people are susceptible to various diseases due to degenerative changes in the nervous system and decline in physical fitness, and essential tremor syndrome is one of them.

Environmental factors (25%):

The occurrence of a disease is more or less related to environmental factors, and the same is true for essential tremor disease, and the reason for regional differences in the prevalence of essential tremor is that there may be some toxic substances in the environment that damage the neurons of the brain.

Familial inheritance (35%):

In the follow-up survey of some essential tremor patients, it was found that essential tremor, an elderly disease, seems to have a certain tendency to cluster in families, and the incidence of essential tremor patients in their relatives is higher than that of the normal population. About 60% of patients have a family history and show autosomal dominant inheritance characteristics, and two pathogenic gene loci have been identified, located at 3Q13 (FET1) and 2P22-25 (ETM or ET2). For essential tremor, although the main factor in the occurrence of the disease is that aging is related to environmental toxins, not all elderly people live in the same environment, and even people who also consume large amounts of pollutants will develop essential tremor.

Therefore, our relevant experts deduce that essential tremor also has a certain familial agglomeration phenomenon, but so far no clear pathogenic gene has been found in sporadic essential tremor patients, therefore, there are many kinds of essential tremor syndrome, and we should not take it lightly.

Essential tremor is an autosomal dominant disorder, the most common extrapyramidal disorder, and the most common tremor condition, with about 60% of patients having a family history. Essential tremor is a single symptomatic disorder, and postural tremor is the only clinical manifestation of the disease. Postural tremor refers to a tremor caused by a limb maintaining a certain posture, which disappears naturally when the limb is completely relaxed.

Tremor is common in the hands, followed by head tremor, and tremor of the lower extremities is rare in patients. Essential tremor is also characteristic of essential tremor that worsens with concentration, nervousness, fatigue, and hunger, and in most cases disappears temporarily after alcohol consumption and worsens the next day. Coping symptoms**.

Disease**. 1 3 patients have a family history with autosomal dominant inheritance, and 2 pathogenic loci have been identified, localized at 3Q13 (FET1) and 2P22 25 (ETM or ET2).

Essential tremor, also known as familial tremor, has a family history in about 60% of patients. No intergenerational phenomenon has been found in multiple essential tremor families, the sex distribution is balanced, and it is generally considered to be autosomal dominant inheritance, which is completely penetrant before the age of 65 to 70 years, and there are also reported cases of incomplete penetrance and sporadic tremor, and the clinical characteristics of sporadic and hereditary people are completely identical, and it is usually considered to be the same disease, but the related genetic abnormalities have not been identified. The bimodal feature of the age of onset of essential tremor suggests the presence of two distinct abnormal genes.

Familial tremor occurs at an earlier age than sporadic cases, suggesting that early-onset essential tremor is more strongly influenced by genetic predisposition, and genetic susceptibility significantly affects clinical subtype characteristics.

There are many causes of essential tremor, but there is no clear cause at present, which may be related to the following factors: 1. Genetic factors, people with a family history of heredity are more likely to be affected; 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. After the occurrence of essential tremor, attention should be paid to it, timely medical treatment, and regular **.

There are many causes of essential tremor that may be 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. After the occurrence of essential tremor, it should be taken seriously and immediately seen a doctor.

A hand tremor is an involuntary, rhythmic shaking caused by repeated muscle contractions and relaxation. Everyone has varying degrees of tremor, called physiological tremor, but most tremors are too mild to be noticed. Tremors can be classified according to their speed, rhythm, frequency of occurrence, and severity.

Motor tremor occurs when the muscles are active, and resting tremor occurs when the muscles are resting, i.e., when the patient is completely relaxed. This type of tremor can be one of the symptoms of Parkinson's disease. Intention tremor occurs when a position is taken.

Essential tremor usually begins in childhood and becomes more pronounced with age. It's not clear. Senile tremor is also a type of essential tremor that appears in old age.

If people with essential tremor have a family history, it is sometimes called familial tremor.

Essential tremor is a disease in which tremor is the only symptom, and this disease is more strange, that is, tremor symptoms, and there are no other symptoms. In addition, tremor often has a family history, so it is related to genetic factors, and there are often several people in the family who develop this disease. However, this disease is relatively not easy to attract attention, because the disease develops slowly, and most patients have relatively mild symptoms, so they do not go through anything**, but there are also individual cases where they shake very badly, unable to sleep, unable to eat, especially doing some fine work to shake more powerfully, to be timely**.

In addition, after drinking alcohol, the tremor will be reduced in some patients.

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 a genetically related movement disorder that can occur at any age, with a higher incidence over the age of 40.

Patients typically present with postural or action tremor in the hands or forearms, some patients may also have head and neck tremors, and some patients may have tremors of the lower extremities. Patients generally do not have other neurological positive signs, do not have hypertonia, generally have slow progression, do not affect the patient's disability, and do not require special **.

Essential tremor, also known as benign tremor, is unknown, the so-called idiopathic is not found, but 60% of patients may have a history of familial tremor, that is, parents, brothers, sisters or grandfathers, grandmothers may have a history of tremor, can appear tremor of the hand, can also appear tremor of the head, the progress of this essential tremor is very slow, this is a kind of postural tremor, generally aggravated when holding objects or nervous, does not appear when stationary, does not need to be treated, the progress is very slow.
