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 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 of essential tremor can also develop essential tremor.

Essential tremor is caused by predisposing factors, and studies have found that patients with familial essential tremor have higher levels of dehydrocamel fluffine, 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 caused by aging. 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.

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, 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 growing evidence that essential tremor or senile tremor is associated with aging, and people aged 65 years with essential tremor are four times more likely to progress to Parkinson's disease.

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.
