Why do I have sudden hand tremors? Why do you suddenly have shaky hands?

Trembling hands are generally referred to as involuntary hand movements, which are uncontrollable and move on their own. Hand tremors are divided into unilateral and bilateral, and are also divided into chronic and acute, and the causes of hand tremors are as follows:

1. Sudden unilateral hand tremor with a large amplitude, considering the nervous system problem, is the problem of the brain, because the brain is responsible for the voluntary movement of the hand;

2. Bilateral involuntary hand movements can also be seen in brain problems;

3. Acute sudden hand tremor, and the amplitude is large, whether it is unilateral or bilateral, it is considered that there is a problem with the brain, and chorea is more common in the nervous system;

4. Chronic is a long time ago or a period of time, trembling is subtle, systemic diseases such as hyperthyroidism, Parkinson's disease will also appear tremor, hand tremor. If it is chronic, it is necessary to pay attention to whether there is hyperthyroidism, of course, hyperthyroidism can also be combined with hyperhidrosis, polyphagia, Parkinson's disease combined with bradykinesia, abnormal gait and so on.

If the tremor is very small, it is okay to go to the doctor, it may be called physiological tremor, and observation is the mainstay. In general, once there is an abnormality, it is better to consult a doctor.

Sudden hand tremors can occur in the following situations:

Essential tremor, essential tremor causes hand tremor is a kind of posture or posture, that is, when the hand is in a certain posture, such as holding chopsticks to pick up vegetables or holding a cup to drink water, there will be hand tremor, which is related to emotional tension, the more nervous and anxious, the more the hand shakes badly.

Parkinson's disease, the hand tremor caused by Parkinson's disease is an involuntary shaking, which is not controlled by the brain's consciousness, and is mainly related to the decline of dopaminergic in the human body, which can be carried out by medopa**.

Sudden hand tremors may be a manifestation of chills, that is, fear of cold, symptoms before fever, pay attention to whether there is fever.

A change in mentality, sudden panic and impatience can also cause sudden hand tremors.

Tired. Rest well. It's also possible that the hand is pressed. This one is neurological.

It may be that there is a problem with the cranial nerves, and it is recommended to go to the hospital immediately for examination, and then treat the symptoms**.

The symptoms of sudden hand tremor are seen in physiological conditions, such as induced by emotional agitation, nervousness, exertion and other factors, which may be caused by neurological disorders. If the hand tremor occurs suddenly in the elderly, acute cerebrovascular disease cannot be ruled out, which may be caused by cerebral infarction or cerebral hemorrhage, and head CT is needed to distinguish it. There is also a sudden appearance of hand tremor, which may be caused by essential tremor, which is related to movement, and generally the more you do fine movements, the more severe the hand tremors.

In addition, it is considered to be senile Parkinson's disease, which is manifested as hand tremors like mud pills, tremors when at rest, and sudden hypoglycemia, and patients are also accompanied by symptoms such as palpitation and sweating.

When there is sudden hand tremor, it is first recommended to take the patient to the local hospital in time, and ask the doctor to judge the main cause of the current hand tremor.

In most cases, it is thought to be caused by endocrine hormone disorders, which are mostly seen in hyperthyroidism or some other endocrine hormone disorder. In addition to hand tremors, patients may also experience palpitation, shortness of breath, and significant difficulty breathing and labor. Endocrine hormone tests show that most cases of inappropriate thyroid hormone secretion occur.

In addition, it is necessary to determine whether it is caused by other diseases. For elderly patients, it is necessary to consider the occurrence of hand tremor due to some central nervous system diseases, such as some elderly people who are prone to resting tremor and some elderly people who have Parkinson's disease are also prone to hand tremor, and then the diagnosis can be further confirmed by endocrine examination and brain MRI.

1. Physiological hand tremors.

The amplitude is small and the speed is fast, and it mostly appears when it is stationary, which is a small, fast, irregular jitter. Physiological hand tremors are often caused by nervousness, fear, and moreEmotional agitation, severe pain, and extreme fatigue may occur, and once the above causes of hand tremors are removed, hand tremors disappear.

2. Pathological hand tremors.

Medically known as "tremor"; Refers to random tremors of the hand, often permanent. There are two main types: resting hand tremor and motor hand tremor. Among them, resting hand tremor is the hand tremor that occurs when the muscles are completely relaxed, that is, in a quiet state.

This kind of hand tremor can disappear when sleeping, and the speed of hand tremor is 4-6 seconds, which is relatively regular, and is typical of diseases such as Parkinson's syndrome. Motor hand tremor is a hand tremor that occurs only during exercise and is worse when the movement approaches the target. For example, when the doctor gives a patient a finger and nose test, he asks the patient to straighten his forearm; Then point your index finger at the tip of your nose; The closer the tip of the index finger is to the tip of the nose, the more pronounced the shaking of the hand becomes.

Hand trembling psychology**.

Reduce self-attention. It means that you want to shift your attention to the specific things you are facing, rather than to your own feelings. This is important.

When you find that you are paying attention to whether your face is red, whether your heart is beating fast, and you are paying attention to this kind of problem, the activity of the nervous system will be involuntarily activated or strengthened. And if you pay less attention to it, you can give it a rest, and its impulse will naturally weaken. In order to reduce self-focus, you need to learn to pay attention to your real problems in the situation, such as your application, your examiner, your environment, etc.

Sudden hand tremors. Tremors are more pronounced when you are stressed or tired. But it's good to have a good rest! Little impact on daily life.

This is your inadvertent subconscious action, and this will become a habit after a long time, otherwise you will really delay things sometimes.

There are many reasons for hand tremors, such as psychological factors, diseases, and so on.

After a long time, you should pay more attention.

Beijing Deshengmen Hospital of Traditional Chinese Medicine - Wen Jihuan - Deputy Chief Physician - What is the cause of hand tremors?

There are several reasons for the sudden shaking of the hand: 1. The most common is related to the patient's mental tension and pressure, which is a physiological reason. 2. If the patient's hand shakes suddenly, if the hunger is more severe, and there are symptoms of palpitation and palpitations, it is considered to be caused by hypoglycemia, which can be determined by measuring blood sugar.

3. If the patient's hand suddenly trembles, if it is manifested as a resting tremor and a mud pill-like change, it is considered to be caused by Parkinson's disease. 4. If the patient's hand suddenly shakes not violently, it may also be caused by essential tremor. 5. If the patient's hand shakes suddenly, if it is accompanied by inflexibility and involuntary movement of the limbs, it is considered to be caused by acute cerebrovascular disease, such as cerebral infarction.

If the patient has sudden hand tremors, a variety of factors should be considered, such as in young patients, and autonomic dysfunction should be considered if precipitating factors such as agitation or nervousness are present. In addition, if the elderly patient has hand tremor, it does not rule out acute cerebrovascular disease, such as cerebral hemorrhage or cerebral thrombosis, etc., and can also cause benign hand tremor due to emotional stress, which is generally an age-related disease with a family history.

The sudden appearance of hand tremors may be caused by the following reasons:

1. This may be a manifestation of peripheral neuritis, that is, there is a problem with the nerve perception of the hand, and the sensitivity is reduced, and the situation will cause shaking. Clause.

2. If the elderly do not rule out the possibility of Alzheimer's disease, it is recommended to observe whether there are other symptoms such as memory loss and cognitive decline. Clause.

3. Some diseases of the head and brain can also cause hand tremors, such as insufficient cerebral blood supply, cerebral infarction, cerebral arteriosclerosis and other diseases.

1. Pathological factors.

1. Essential tremor: the disease is unknown, mainly affecting the upper limbs and head. The main manifestation is hand tremor when doing fine movements, such as writing, holding chopsticks, buttoning, etc.

Hand tremors are more pronounced during emotional stress and fatigue, and are relieved or completely disappeared when the mind is relaxed or resting. Essential tremor progresses very slowly or non-progressively and has little impact on daily life.

2. Parkinson's disease: It has been clinically found that Parkinson's disease is the most common cause of hand tremor in middle-aged and elderly people. If left unchecked**, the symptoms will get worse and worse.

This condition requires the help of a specialist.

2. Psychological factors.

If pathological factors are ruled out, another common cause of hand tremors** is caused by psychological factors.

Anticipatory anxiety disorder. This kind of problem often creates a situation that frightens the patient. For example, if you are very worried about your hands shaking in the presence of others at work, your hands are really shaking when they come to you.

If this symptom of shaking hands is often present, it may be a manifestation of Parkinson's disease. Patients with Parkinson's disease experience tremors in the hands as well as shaking of the head and limbs when they are emotionally agitated, overworked and stressed. If the disease is severe, it will be difficult to walk and start, and after starting, it will become faster and faster.

It is also possible that the hands are overworked, and the muscles are tired due to overexertion, and the trembling of the hands can be done after exertion, and the hand muscles can be relaxed and massaged after exertion, which can improve the symptoms. If there is often a recurrence of hand tremors, it is best to go to a regular hospital to clarify the symptoms.
