Who is prone to essential tremor? What is essential tremor?

First, essential tremor is the most common movement disorder, mainly postural and motor tremor in the hands, head, and other parts of the body. Essential tremor has a conflicting clinical nature, being a mild single-symptomatic disease on the one hand, and a common progressive disease with significant clinical variation on the other. Tremor is aggravated by concentration, nervousness, fatigue, and hunger.

Most cases disappear temporarily after alcohol consumption and worsen 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. There is also a family history in 60% of patients, also known as familial tremor, which is not found to enlarge in multiple families of essential tremor, and is evenly distributed by sex, which is generally considered to be autosomal dominant inheritance, and is completely penetrant before the age of 65 to 70 years.

It is unclear that its production may be the result of a combination of peripheral muscle spindle afferents and central autonomic oscillators. It can occur at any age, but is more common in the 30s and 50s to 60s.

Middle-aged and elderly people are prone to many diseases, among which the incidence of essential tremor is very high, and essential tremor has also become a major killer that threatens people's health.

The most susceptible population is the elderly.

Uncontrollable tremors in the hands, head, and even voice.

The disease manifests only as tremor and does not affect life expectancy.

Onset increases with age, often with a family history.

Drugs are preferred**, and surgery may be considered in severe cases.

Disease definition. Essential tremor, also known as essential tremor and familial tremor, is an autosomal dominant genetic disease, which is mainly manifested as involuntary tremor of the upper and lower limbs or head and face, and sometimes vocal tremor.

The conventional wisdom is that essential tremor is a benign movement disorder that manifests only as tremor and does not affect life expectancy. However, there is now increasing evidence that essential tremor or senile tremor is associated with aging, with patients aged 65 years progressing to Parkinson's disease.

chance increased by a factor of 4.

Epidemiology. The incidence of essential tremor is about % with age, with an incidence of about 40 years of age and about 65 years of age.

Essential tremor tends to run in families, with 30 to 50 patients having a family member with essential tremor. Patients with a family history of the disease develop the disease at an earlier age, most before the age of 20, and patients without a family history usually develop the disease after the age of 40. Labor loss due to tremor usually occurs 10 to 20 years after the onset of the disease.

Type of disease. Depending on whether the patient has a family history, it can be divided into familial tremor and sporadic cases. The clinical features of the two groups of patients are almost identical.

People with high blood pressure and low blood pressure (heart disease).

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

It is easy to develop it if there is a family history of hereditary disease.

Essential tremor is the most common movement disorder in clinical practice, which is mainly manifested as postural or action tremor, and some head or voice tremors can be seen, with an incidence of about 5% and the elderly population can rise to 20%. Essential tremor progresses slowly and has a single symptom.

1. Most of them are benign movement disorders. However, essential tremor is a multisystem disorder that includes motor symptoms such as intention tremor and ataxia, as well as nonmotor symptoms such as cognitive dysfunction, affective impairment, and hearing loss, and can also increase the risk of Parkinson's disease.

Essential tremor is still relatively common in our lives, but most people in life do not know very well, because the early manifestations of the disease are very slight, and it is normal for people not to understand, and they feel that it is not necessary, because the performance at the beginning does not affect the situation of life very much, and they feel that there is no threat. Hand tremors in young people are mostly caused by essential tremor or hyperthyroidism. Parkinson's hand tremor is not the same as hand tremor caused by essential tremor or hyperthyroidism.

Parkinson's disease is a chronic degenerative disease of the central nervous system that causes a lack of dopamine in the brain, eventually limb tremors, and other movement disorders. There are actually many types of hand tremors.

When people are particularly excited, nervous or weak, their hands will tremble, which is called physiological trembling; In addition, there are pathological tremors, including resting tremors, postural tremors, etc. One of the symptoms known as resting tremor is the manifestation of Parkinson's disease. Resting tremor, when a normal person puts their hands on their knees, their hands do not shake.

However, even if the Parkinson's patient's hand is placed on the knee, it will still shake involuntarily, and the shaking is regular, shaking 3 times per second, and the action is in the shape of a rub. Postural tremor, postural tremor refers to the fact that the hand does not shake when it is stationary, but it will appear when making movements or posing for a certain position, such as holding chopsticks or holding a cup. If a person's hands do not shake normally, but only when they hold chopsticks or make movements, it is generally not Parkinson's disease.

Because the tremor of Parkinson's patients is a resting tremor.

Essential tremor is an autosomal dominant disorder and is the most common extrapyramidal disorder characterized by tremor or rhythmic involuntary movements of the head, face, jaw, tongue, and lower extremities.
