How many types of essential tremor are there? What are the typical features of essential tremor?

In addition to the four main symptoms of resting tremor, muscle rigidity, decreased movement, and unsteady walking, some patients with essential tremor also have some special symptoms.

1.SalivationThere are many patients with essential tremor who often drool, and in severe cases, they need to be wiped constantly with a handkerchief.

2.Patients with oil-faced essential tremor always have a shiny forehead.

The only symptom of essential tremor is tremor, occasionally reported with abnormal tone and slight gait, patients usually start from the upper limbs, mainly affecting the upper limbs, bilateral upper limbs symmetrical onset, can also unilateral upper limbs onset, once the upper limbs are affected, often upward to the head, face, tongue, mandible, involving the trunk and bilateral lower limbs is rare, only in the late stage of the course of the disease, and the degree is milder than the upper limbs. The main manifestations are postural tremor, which can contain motor, intentional or resting tremor components at the same time, and the tremor may be aggravated in the movement directed at the purpose, the frequency of tremor is 4 8 Hz, the frequency at the onset is 8 12 Hz, and the frequency gradually decreases and the amplitude gradually increases with the increase of the course and age of the disease. The typical symptoms are rhythmic abduction of the hand, adduction-like tremor and flexion-extension tremor, supination-supination tremor (similar to Parkinson's disease) is very rare, the written words may be deformed, but not as a small handwriting, another commonly affected part is the craniocervical muscle group, the head, tongue or vocal muscles can be involved, manifested as severe postural tremor and head tremor of the patient's hand, including vertical "nodding" movements and horizontal "shaking the head" movement, soft palate, tongue tremor can cause dysphonia.

Essential tremor is a functional, neurological disorder that manifests only as a motor symptom of tremor and is considered to be a slow-progressing, symptomatic disorder.

1. Benign movement disorders. The main symptoms of essential tremor are random shaking of the hands, head and possibly other parts of the body, rhythmic shaking, and generally when the condition is mild, the shaking amplitude is large, fast, easy to be controlled by oneself, and often appears when it is completely relaxed or nervous. In severe cases, the amplitude is small, but it lasts for a long time and is difficult to control.

Rarely, patients develop tremor of the lower limbs, which worsens with concentration, nervousness, fatigue, and hunger, and disappears temporarily after drinking alcohol and worsens the next day. The shaking is more obvious when holding chopsticks, serving tea and pouring water, threading needles and threads, etc., which is also a characteristic of essential tremor.

Essential tremor is a common movement disorder in which tremor is the only manifestation. 1 3 The patient has a positive family history, which is inherited in an autosomal dominant manner, and the pathogenesis and pathological changes are unknown. Essential tremor has an insidious onset, progresses slowly, and may resolve long-term.

It can be seen at any age, but it is more common in middle-aged and elderly people over 40 years old, tremor is the only clinical symptom, mainly manifested as postural and action tremor. Tremor can be temporarily relieved after taking propranolol, and can be aggravated by emotional agitation or nervousness, fatigue, cold, etc.

Hello, the typical feature of essential tremor is postural tremor, and the more common one is hand tremor.

Essential tremor is characterized by postural tremor, action tremor, and rhythmic involuntary movements, usually of the upper limbs, face, jaw, tongue, or head, and less often of the lower limbs.

Take things to do fine work hand trembling, many people are nervous and excited, haircut concentration will appear head tremor, nervous whole body trembling, palpitation, alcohol reduction, aggravation after drinking, this disease will become more and more serious with the time of illness.

Essential tremor, also known as familial or benign essential tremor, is an autosomal dominant genetic disease, the most common extrapyramidal disease, and the most common tremor condition.

Shaking hands is only one of the most easily found symptoms of essential tremor, and it is also a symptom that has a great impact on the patient's life and work, unable to write normally, unable to drive normally or even unable to eat normally, and will completely lose the ability to take care of himself when he reaches a certain age, so it is necessary to control its symptoms in time.

Causes physical and social embarrassment, usually does not cause disability, in some cases tremor can prevent the hand from performing fine movements such as writing, when the laryngeal muscles are affected, copying can affect speech, and the lower limbs are often not affected.

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.

Significant limb tremors are evident in nervousness, agitation, fatigue, hunger, and concentration.

The disease is more common in the late teens or early adulthood, and tremor is the only clinical symptom, manifesting as postural tremor and action tremor, often in one or both upper limbs, often with the head also affected, and less often in the lower extremities. In some patients, tremor can be temporarily reduced after drinking alcohol, and tremor can be aggravated by emotional agitation or nervousness, fatigue, and cold.

Pathology**.

Most of these diseases are neurological diseases, and some scholars believe that the disease is an extrapyramidal disease, or a sympathetic nerve reflex disorder.

Symptoms of essential tremor include:

1. Postural tremor: It is mainly manifested as obvious tremor when the hand is in a certain position;

2. Action tremor: It is the most characteristic manifestation of essential tremor, which is mainly manifested as obvious tremor when the hand completes a certain action, such as the direction shift during the clinical finger nose test. It can be distinguished from resting tremor in Parkinson's disease.

Symptoms of essential tremor usually include tremors in the hands or legs, and may also cause tremors in the head and neck, and the voice may also tremble, which may be due to genetic reasons, may be affected by the surrounding environment, or may be due to excessive tension, and the body can be properly massaged. The symptoms of essential tremor are manifested as tremors in the head or legs, and also as tremors in the trunk and facial muscles.

The main typical symptoms are shaking hands, shaking heads, and shaking legs.

Essential tremor, also known as familial or benign essential tremor, is an autosomal dominant disorder, the most common extrapyramidal disease, 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**.

Essential tremor (PEI) is the most common movement disorder, mainly caused by posture and motor tremor in the hands, head and other parts of the body. SHU 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.
