Trembling hands

Introduction Trembling is a regular and repetitive involuntary body shake that can occur throughout the body, but with multiple limbs. The amplitude can be large or small, the speed can be fast or slow, usually between 1 and 10 times per second. . Hand shake is divided into physiological hand shake and pathological hand shake: the amplitude of physiological hand shake is small and fast, and it appears mostly at rest. It is a small, fast and irregular shake; pathological hand shake, Medically known as "tremor"; refers to the involuntary vibration of the hand, often permanent.

Cause

Physiological hand shake often occurs in the case of mental stress, fear, emotional agitation, severe pain and extreme fatigue. Once the above-mentioned causes of hand shake are eliminated, the hand shake disappears. Pathological hand shake is mainly divided into two types: static hand shake and exercise hand shake. The static hand shake is the hand shake that occurs when the muscle is completely relaxed, that is, in a quiet state. This kind of hand shake can disappear when sleeping, the hand shake speed is 4-6 times / sec, more regular, typical diseases such as Parkinson's syndrome. Exercise hand shake is the only hand shake when exercising, and the jitter is aggravated when the motion is close to the target. If the doctor gives the patient a finger-nose test, ask the patient to straighten the forearm; then use the index finger to point to the tip of the nose; the closer the tip of the index finger is to the tip of the nose, the more obvious the hand shakes. The movement of the hand movement is irregular, the amplitude of the vibration is large, and it is enhanced by the emotion, which is common in the lesions of the cranial nerve and the upper limb nerve.

Regularity is its greatest feature, and any involuntary involuntary movement is not trembling. Here are some of the more common trembling:

1. Physiological tremors.

2. Physical or hereditary trembling.

3. Trembling of Parkinson's disease.

4. Tremor caused by cerebellar lesions.

Symptoms of Parkinson's disease include: mandibular and lip muscle tremor (involuntary shaking), affecting eating and talking, mouth drooling, unclear language, limbs burnout, shaking hands, can't take tableware, can't write, gait, walk difficult. When you are overworked, you will feel twitching in your hands and feet and shake your head. Pingming has a sallow complexion and a dull expression. It is a "mask face". The two upper limbs are curved like the shape of a basketball player when shooting. Some patients have incontinence. Symptoms of autonomic nervous system in patients with Parkinson's disease are increased saliva, sebum spillage, increased sweating, increased body temperature, lower extremity edema, and poor appetite. Some patients often sweat a lot at night, and some patients get worse when the weather is hot and their body temperature rises. Older patients are prone to mental symptoms, and depression is common. Among the elderly, the early stages of the disease are sometimes difficult to find. Because the elderly suffer from Parkinson's disease, often with less movement as the first symptom, walking is slow. This is easily overlooked, and it is wrong to assume that the actions of the elderly are not as agile as young people. Therefore, if the elderly do not have other reasons (such as poor eyesight), and the movement is slow, it is necessary to think of the possibility of Parkinson's disease, and a detailed neurological examination is required.

Differential diagnosis

Physiological tremor

It is a normal physiological phenomenon rather than a disease, and the trembling pattern is small and fast. Normal people have such tremors but are not obvious and unconscious. In some cases, physiological tremors will be strengthened and become more prominent and obvious. Common causes of strengthening physiological tremor are as follows: emotional fear, cold blood sugar Low, hyperthyroidism, alcohol or drug withdrawal symptoms, drugs or caffeine, the highest proportion of all trembling. The cause of this kind of tremor is unknown. It is generally considered to be related to personal physique. Half of them have a family history, so this tremor has a great relationship with heredity.

2. Physical or hereditary tremor

It occurs in all ages, but the older the tremor is, the more severe it is. It mainly appears in the hands, and it often appears on the head, even the sound is trembling. It is especially noticeable when the hands are in a fixed position or a fine movement, and the rest is relieved. Some patients experience a reduction in the degree of tremor after drinking. The course of this tremor is slowly deteriorating, and there are no subtypes of other neurological symptoms or hereditary trembling that have some variability, such as: tremors that occur only during movement. Trembling that occurs during rest and maintenance in a fixed position, trembling (writing trembling) when writing, simple trembling, chin tremor, simple tongue trembling, standing trembling.

3. The tremor of Parkinson's disease

Occurred in middle-aged and old people, mainly in the hands and feet, especially at rest, will be relieved when doing movements, this feature is contrary to physical or hereditary tremors. The course of disease continues to deteriorate, and with other Parkinson's disease Nervous system symptoms.

4. Trembling caused by cerebellar lesions

This tremor is caused by cerebellar lesions and is characterized by no or very slight rest at rest, mild when maintaining a fixed posture, but particularly noticeable when approaching the target, and with other cerebellar symptoms such as balance disorders.
