What are the symptoms specific to essential tremor

Symptoms of essential tremor are manifested as trembling hands, poor speech, intermittent speech, and even slurred speech, and some movements cannot be completed.

Postural tremor and action tremor are the only clinical manifestations of the disease and are often found in one or both upper limbs, often with the head 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.

Not only can it cause physical and social embarrassment, but it can also interfere with fine motor activities such as writing, and when the laryngeal muscles are affected, it can affect speech.

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

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.

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.

The only symptom of essential tremor is tremor, with occasional reports of intonation and slight gait abnormalities. 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, and mandible. Bilateral lower extremities of the trunk are rare, occur only late in the course of the disease, and are less severe than those of the upper extremities.

Typical symptoms. Postural tremor.

It can contain both motor, intentional, and resting tremor components. Tremor may be worse with movement toward the purpose. The frequency of tremor is 4 8 Hz, which gradually decreases and increases in amplitude with increasing course and age.

Severe postural tremor of the hand.

Presents with rhythmic abduction of the hand, with adduction tremor and flexion-extension tremor, and pronation and supination tremor are rare. The written word may be distorted, but it will not appear as too small.

Affects fine motor skills.

Tremor affects fine motor skills after 10 to 20 years of onset, reaching a peak in the 6th decade of onset. 86% of patients by the age of 60 to 70 years can affect social activities and life skills, including writing, drinking, eating, dressing, speech, and manipulation.

1.Manifestations of essential tremor: Essential tremor, also known as essential tremor, is a common movement disorder, familial tremor or hereditary tremor, is a neurological disorder characterized by uncontrollable tremor of the hands, head, voice or other parts of the body, essential tremor can occur at any age, but it is more common in middle-aged and elderly people over 40 years old.

2.The **:** of essential tremor is unknown, and some patients may have a genetic mutation that causes the onset of the disease, and patients with essential tremor who have a family history of tremor have an earlier age of onset, mostly before the age of 20.

3.What are the risk factors for essential tremor: Genetic mutations:

Essential tremor caused by genetic mutations is hereditary. If one parent has a mutated gene for essential tremor, there is a 50% chance that a child will develop essential tremor[3]. Age:

People aged 40 years and older are more likely to develop essential tremor.

4.Precautions for life prevention: Avoid caffeine intake because caffeine can worsen tremor Some patients notice some improvement in tremor after drinking, but know that drinking alcohol does not completely solve the tremor problem.

Once the effects of alcohol have subsided, tremors tend to worsen. In addition, it is gradually necessary to increase the amount of alcohol consumed to relieve the tremor, which may lead to the patient drinking too much and learning to relax. Stress and anxiety can worsen tremors.

Relaxation can reduce tremors. Although it is not possible to completely eliminate stress in life, it is possible to learn to take some relaxation methods to cope with stress, such as massage or meditation, which can allow the patient to relax, reduce stress, change lifestyle, and use lighter tremors for daily activities.

Essential tremor, also known as familial or benign essential tremor or essential tremor, is a common movement disorder with a certain genetic predisposition and tremor as the only manifestation. Essential tremor is a lifelong condition that is not currently available, but it does not affect the patient's lifespan. There is no age limit for this disease, but it is more common in middle-aged and elderly people, and it can cause hand tremors, head tremors, etc.

**。The pathogenesis of essential tremor has not yet been fully elucidated, but is related to genetic factors and is influenced by environmental factors.

Main**. Genetic factors.

30% to 50% of patients with essential tremor have a family history of autosomal dominant inheritance, and five causative loci have been identified.

Other factors. At present, some studies have found that dehydrocamel pine may be related to essential tremor, because in the investigation, it has been found that the level of dehydrocameline in patients with familial essential tremor is generally higher than that of the normal population, and the substance is a neurotoxic substance that is higher in meat cooked at high temperatures for a long time. In addition, the heavy metal lead may also be associated with essential tremor.
