What are the causes of tremors? What causes tremors?

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 can also get the disease.

There are three main causes of limb tremor:

Patients with hyperthyroidism and hyperthyroidism often have symptoms of limb tremors. The diagnosis of hyperthyroidism is not too difficult, and only blood tests are needed to determine the relevant indicators, and the diagnosis can be basically defined. If it is caused by hyperthyroidism, after giving the corresponding **, the thyroid gland function is normal, and the symptoms of limb tremor will disappear.

Parkinson's disease or Parkinson's syndrome, this disease is seen in older people, in addition to limb tremors, there will also be bradykinesia, that is, slow movements, buttoning, tying shoes, putting on clothes, etc., all movements in daily life are very slow. Walking is also slow, the feet seem to be glued to the ground, unable to take a step, and the patient often feels that the limbs have lost their flexibility and are relatively stiff.

Benign essential tremor, the cause of which is not well understood, can occur at any age. It is mainly manifested as limb tremor when doing fine motor movements, such as holding a water cup, writing, buttoning, etc., and there are no other symptoms except tremor.

The specific cause of limb tremor requires a consultation with a neurologist. According to the physical examination, combined with laboratory examinations, a preliminary diagnosis is given, and the corresponding ** is given.

1. Essential tremor caused by pathological factors. The disease is unknown, involving the upper limbs and head, and is mainly manifested as hand tremors when doing movements, such as writing, holding chopsticks, buttoning and so on. Of course, once a person is emotionally stressed, hand tremors will be more obvious.

However, the tremor lessens or even disappears completely when people are relaxed or resting, but the neurological examination is not abnormal except for hand tremors. The most effective way to treat essential tremor is to use drugs, and many drugs now have a good effect on tremor symptoms, which can be improved as long as you take the medicine on time. Essential tremor progresses very slowly or non-progressively and has little impact on life.

2. The main symptom of Parkinson's disease is hand tremor, which is a disease that occurs more often in the elderly, and the symptoms of hand tremor mostly appear in the elderly. In addition to hand tremors, it is accompanied by symptoms such as slow movements, stiffness of the moving limbs, and poor balance function. Parkinson's disease needs to be prompted**, otherwise the symptoms will not only not be relieved, but will become more severe.

3. Anxiety disorders caused by psychological factors, which are often caused by a situation in which the patient himself or herself pre-anticipates that he feels fearful. The things that I am afraid of, the things that I expect to encounter, will feel anxious and restless in the process of being staged. Immediately after that, the hands will shake involuntarily, and the symptoms will become more and more severe with the rapid heartbeat.

In anticipatory anxiety disorder, this fear triggers a vicious cycle. In this vicious circle, patients are often unable to extricate themselves.

All in all, once you find that you have symptoms of hand tremors, you should still get a proper examination with your doctor in time. In order to understand and clarify your own **, under the correct guidance of the doctor, in a timely manner**, to reduce the impact of hand tremors on life.

When people are very tired, or when they are nervous, they are prone to muscle tremors. Or when the spirit is more nervous, there is also cerebellar disease** is a muscle tremor caused by this factor, mainly in the upper limbs. And the speed of this tremor is not fast, and there is no pattern to follow.

The closer you get to the affected area, the more pronounced the tremor feels.

In general, there are many causes of tremor, but in simple terms, parkinsonism and muscle weakness can cause tremor.

Physiological tremor: In some cases, most normal people will have a subtle rapid tremor in the hands when the upper limbs are stretched forward. Reinforcement of physiological tremor can be seen in anxiety, nervousness, fatigue, and metabolic disorders (

Tremor is the most common manifestation of Parkinson's disease, but it is not that tremor occurs or that Parkinson's disease occurs, tremor has primary tremor and physiological tremor, and tremor is classified as Parkinson's disease tremor, dystonic tremor, task-specific rolling tremor, and cerebellar tremor.

There is a very common reason for it to seek medical attention if there are other symptoms because it is too cold.

Body tremor is a symptom, and the cause of its onset depends on the part of the trembling, including the branches: 1. If it is a one-handed tremor that occurs in a quiet state and is combined with pre-branch impairment, walking disorder, difficulty in turning, and difficulty in starting, the possibility of Parkinson's disease is highly suspected; 2. If it is tremors in both hands, first of all, it is necessary to rule out whether there is hyperthyroidism.

Most of the body tremors are caused by physiological factors and mental factors, and only a few are really caused by the disease. Lust is angry, the heart and liver are hot, and the wind is inside.

Physiological tremor: In some cases, most normal people experience a subtle rapid tremor in the hands when the upper limbs are stretched forward. Enhancement of physiologic Lie-bradytremor may be seen in anxiety, nervousness, fatigue, metabolic disorders (eg, withdrawal ,.. before the alcohol beam).

The first reason is physiological tremor, such as when the patient is nervous, frightened, and excited, the sympathetic nervous system is excited, which leads to the release of a large amount of adrenaline and norepinephrine, which will cause tremor in the limbs, and this situation is not too worrying.

The second reason is to pay attention to whether there is extrapyramidal disease, such as the patient's Parkinson's disease will cause limb tremor, this tremor is generally bilateral asymmetrical, mainly resting tremor, which will be reduced when moving, and generally accompanied by clinical manifestations such as bradykinesia and muscle rigidity. Essential tremor is also an extrapyramidal disorder that is dominated by postural tremor and is different from Parkinson's disease.

The third reason is to pay attention to whether the patient has abnormal liver function and abnormal thyroid function, which can cause tremor.

Body tremors are generally seen in the following disorders:

Clause. 1. Essential tremor, more common in people over 40 years old, can appear head shaking, gradually appear body shaking, essential tremor generally does not need to give special drugs **, if the patient tremor is more obvious, you can take some drugs, such as propranolol, etc.

Clause. Second, it is necessary to pay attention to Parkinson's syndrome, the most common is Parkinson's disease, patients can have tremors in one limb, which is more obvious when it is quiet. As the disease progresses, patients can have increased muscle tone, gait panic, slow movements, etc., and drugs such as medopa can be given.

Clause. 3. It is necessary to pay attention to the body tremor caused by hyperthyroidism, patients often have excessive sweating, emaciation, and irritability at the same time, and it is recommended to go to the hospital for thyroid function test to make a clear diagnosis.

Essential tremor is also known as familial tremor, is a genetic disease, mainly caused by chromosomal abnormalities, generally after the occurrence of essential tremor, if you are younger, then the symptoms are relatively stable, but with the increase of age or the decline of the body's immunity, the symptoms of essential tremor will become more obvious.
