What causes essential tremor? What causes essential tremor?

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. 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.

Typical symptoms. 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, leading to more severe functional impairment, and patients often have difficulty controlling tremor, thus affecting work and daily life.

Essential tremor reacts differently to alcohol, some patients can reduce tremor by ingesting a small amount of alcohol, but after 42% and 75% of patients drink alcohol, the tremor decreases for only 2 4 hours, and the tremor worsens the next day.

Causes of essential tremor: 1. Genetic predisposition: Although the occurrence of essential tremor is related to aging and environmental toxins, not all elderly people or people exposed to the same environment, even people who also smoke a large amount of MPTP will 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, and China is constantly entering an aging society, which is also the main factor for the rising incidence.

3. 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 in their relatives 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 invading 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.

The only symptom of essential tremor is tremor, which has occasionally been reported to be accompanied by anomalies in intonation and gait. Patients usually start with the upper extremities and mainly affect the upper limbs, but can also affect the head, legs, trunk, voice, and facial muscles. Presents with postural tremor and may contain both motor, intentional, or resting tremor components.

Tremor may be worse with movement toward the purpose. The frequency of tremor is 4 8Hz. The frequency at the onset of the disease is 8 12 Hz, and the frequency gradually decreases and the amplitude gradually increases with the increase of the course of the disease and age.

Psychological research on patients with essential tremor has received more and more attention. Secondary social anxiety was reported in 30% of patients with essential tremor, and the degree of anxiety was negatively correlated with age and positively correlated with the degree of impairment in social functioning, but not with the severity of tremor and the duration of illness.

Essential tremor is an autosomal dominant disorder and is the most common extrapyramidal disorder. It is a hereditary disease, pay attention to rest, don't get tired, take medicine on time, maintain a good mood, and slowly recuperate.

Typical symptoms are rhythmic abduction and adduction tremor of the hand, flexion and 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.

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.

Also known as essential tremor, it is an autosomal dominant disorder.

Its cause is unknown, its onset is insidious, it progresses slowly, and can occur at any age. It is mainly manifested as motor tremor or postural tremor, which is generally dominated by the upper limbs, and some patients will accumulate their head or lower limbs. Exertion and agitation can trigger flare-ups or exacerbations.

There is no specific way after the onset of this disease, mainly symptomatic, and the commonly used drugs are mainly propranolol. If psychiatric symptoms are comorbidden, the choice of drug should be tailored to the condition and should be used under specialist guidance. Surgery is an option for severe disease or insensitivity to medications**.

The causes of essential tremor include the following: 1. Aging. 2. Familial hereditary: Essential tremor seems to have a tendency to gather in families, and the incidence of essential tremor patients in their relatives is relatively high.

This is a question that you have to ask and ask! ⚡️

Ageing: this is the main reason why essential tremor is preferred in older people. The average person is susceptible to various diseases due to the decline in physical fitness in old age, and essential tremor syndrome is one of them.

Environmental factors: The occurrence of a disease is more or less related to environmental factors, and the same is true for essential tremor, and the reason why there are 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.

The causes of essential tremor include the following: 1. Aging. 2. Familial hereditary:

Essential tremor appears to have a tendency to cluster in families, with relatives of people with essential tremor having a higher incidence than the normal population. 3. Environmental factors: Epidemiological investigations 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.

4. Genetic predisposition: Although the occurrence of essential tremor is related to aging and environmental toxins, not all elderly people or people exposed to the same environment, even those who also smoke a large amount of MPTP will develop essential tremor.

There are many causes of essential tremor, but there is no clear cause and 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, attention should be paid to it, timely medical treatment, and regular **.

There are many causes of essential tremor, but there is no clear **, which may be related to the following factors: genetic factors, people with a family history of heredity are more susceptible to environmental factors; long-term exposure to special drugs or chemical poisons; consumption of allergens such as seafood; Essential tremor can also be caused by cryptogenic causes of involuntary hand tremor after cold or exertion. After the occurrence of essential tremor, sufficient attention should be paid to seek medical attention in time and regular **.

There are various causes of essential tremor, such as drinking alcohol, eating spicy food, staying up late for a long time, and not having a good rule, it is easy to cause essential tremor, so we should pay more attention to this factor to avoid the occurrence of essential tremor.

Essential tremor is an autosomal dominant movement disorder, tremor is the only clinical manifestation, the early stage is generally not severe, can be well controlled by drugs, if not timed** symptoms can gradually worsen with age, may affect daily life, but can not**.

The essence of essential tremor is a movement disorder caused by a genetic mutation, which is where it comes from. Since it is not possible, it is necessary to follow the doctor's guidance according to the condition.

Patients with mild symptoms generally do not need **, early tremor symptoms, about 3% can be relieved on their own, patients need to avoid anxiety, drink caffeine, take thyroxine and other drugs.
