How to distinguish between hand tremors? How to distinguish between hand tremors

There are many causes of hand tremors, the first of which is Parkinson's disease, which is characterized by resting tremor with bradykinesia, special posture, gait abnormalities, and increased muscle tone. Resting tremor refers to the patient's hand tremor when the patient is quiet, generally 4-6 pill-rubbing shakes per second, which decreases during activity and disappears during sleep, which is resting tremor. There is also a type of tremor caused by cerebellar lesions, which refers to the patient's severe tremor when he is active, especially when he is close to the target, and the symptoms may be slightly reduced when he is quiet, which is a cerebellar lesion.

There is also essential tremor, which refers to unexplained tremor that can be seen in patients of all ages, especially in the elderly, and may be related to arteriosclerosis. The more nervous and anxious the more anxious the more it will tremble, and in severe cases, it will affect daily work and life, and may not be able to hold a pen, and it may be difficult to write. Therefore, patients with simple hand tremors must see a neurology department in time and ask a specialist for a detailed physical examination.

Hand tremor, manifested as involuntary rhythmic tremor, is divided into physiological hand tremor and pathological hand tremor.

Physiological hand tremor, its amplitude is small and fast, mostly appears at rest, often in the case of mental tension, fear, emotional agitation, severe pain and extreme fatigue, once the above causes are eliminated, hand tremor will also disappear, will not affect physical health.

Pathological hand tremor, medically known as "tremor", refers to the involuntary shaking of the hand, often permanent, and its root cause may be due to damage to areas of the brain involved in motor coordination.

Pathological hand tremors may be a sign of these four conditions.

In addition to physiological hand tremors, pathological hand tremors may be a precursor to many diseases, such as the following:

1. Parkinson's disease. Professor Liu Chengyong of the Department of Neurosurgery of the Third Affiliated Hospital of Southern Medical University said in an interview with family doctors**: Patients may only have one side of the body (left or right) affected at first, some of which may first manifest as a slight tremor of one finger, and some may manifest as slow fine movements, and as the disease progresses, symptoms will appear on both sides of the body.

The most typical manifestation of the disease is the joint movement of the thumb and index finger 3 to 4 times per second, such as "pill-rubbing" movements, which can lead to stiffness of the limbs, decreased movements, unsteady walking, and shaking of the legs, feet or jaw with the prolongation of the disease.

Generally, it is more common in middle-aged and elderly people aged 50 to 60 years old, slightly more in men than in women, and the incidence rate accounts for about 75%-80% of all patients.

What diseases may be associated with hand tremors?

Whether it's resting tremor due to Parkinson's disease, convulsive tremor due to epilepsy, postural tremor due to essential tremor, or motor tremor due to cerebellar disease, hand tremor can be the main symptom.

However, different diseases can generally manifest as a combination of symptoms, such as:

The main symptoms of Parkinson's disease can be muscle stiffness and bradykinesia in addition to resting tremor, which is mainly manifested by hand tremor;

Epilepsy, in addition to hand tremors, can also manifest as secondary generalized convulsive seizures or electroencephalogram (EEG) for epileptic discharge;

Essential tremor generally has a family history, and is usually manifested as involuntary tremor of the head and upper limbs, which is aggravated by tense exercise and relieved by rest and alcohol consumption;

Motor or intention tremor due to cerebellar lesions is usually diagnosed with a clear history of cerebellar injury and other signs and symptoms of neurologic impairment, as well as magnetic resonance imaging (MRI) or CT.

What medications might be associated with hand tremors?

Drug-induced tremor, also known as drug-induced tremor, is associated with a variety of drugs, generally related to age factors, with the increase of age, the speed and ability to metabolize drugs are reduced, therefore, older people are more common than younger people.

The most common drugs that cause tremor are:

gastric motility drugs, such as metoclopramide ;

Antipsychotic drugs, such as chlorpromazine, perphenazine, haloperidol, etc.;

Antidepressant; antiepileptic drugs;

antihypertensives;

antibiotics, etc. If you experience tremors after taking or adding doses of medications, it is important to consider factors related to the medication.

What environmental factors might be associated with hand tremors?

Hand tremor tremor is mostly related to physiological factors and mental factors, and the real disease still accounts for a small part, so it is necessary to pay attention to hand tremor caused by physical and psychological factors.

Emotional stress, stress, depression, anxiety and other factors may cause hand tremors, but this tremor is mostly related to mental factors, which are reduced or disappeared after the removal of mental factors, so it is easy to identify, but if the predisposing factors persist, it may lead to aggravation of symptoms or even become permanent symptoms.

Hand tremor, medically known as tremor, is a symptom, which is generally divided into physiological hand tremor and pathological hand tremor. Physiological hand tremors, self-adjustment or rest, and then return to automatic recovery. If hand tremors persist in progress, pathologic hand tremors are considered.

The factors that may occur are more complex, such as hyperthyroidism, Parkinson's, essential tremor, drug-induced tremor, cervical spine compression, etc., and it is necessary to go to a regular hospital for a detailed diagnosis, and then carry out the exact **, follow the doctor's instructions. The causes of hand tremor are generally more common in overwork of hand muscles caused by long-term hand activities, as well as hand tremors caused by emotional agitation, tension or fear, etc., which can usually be relieved by rest and emotional regulation, or may be caused by the following diseases, which need to be treated accordingly

1. Hypoglycemia: If hand tremor is combined with symptoms such as palpitation and sweating, it may be caused by hypoglycemia, and it is recommended to conduct a blood sugar check, and you can eat appropriately to promote the relief of symptoms;

2. Parkinson's disease: common in the elderly, resting tremor can occur, and its hand tremor is mainly manifested as the index finger and thumb showing mud pill-like movements. It can be controlled by drugs, but it cannot be completely eliminated, common drugs such as levodopa, trihexyphenidyl hydrochloride, amantadine, etc., in addition, ****, psychological ** and good care can also improve symptoms to a certain extent;

3. Hyperthyroidism: excessive release of thyroid hormone causes hypermetabolism and sympathetic nerve excitation, and hand tremors occur, as well as symptoms such as recent weight loss, excessive sweating, eye protrusion and irritability. It is recommended to perform thyroid function tests to assist in diagnosis, and drugs are often used to inhibit thyroid hormone synthesis in clinical practice, such as methimazole and propylthiouracil, and can also be removed by surgery when the drug is ineffective or accompanied by goiter**;

4. Essential tremor: **Unknown, it can be manifested as shaking of the hands, mainly on one side, which will have different degrees of impact on daily life such as writing and eating, aggravated when nervous or overfocused, reduced after a small amount of alcohol, and some patients have a family history. If it does not affect daily work and life, it can be left untreated, and if it is affected, oral alolol hydrochloride tablets and propranolol can be selected to reduce the symptoms of hand tremor;

5. Drug-induced tremor: Gastric motility drugs such as metoclopramide, calcium antagonists such as flunarizine, and some antipsychotic drugs such as chlorpromazine, haloperidol, etc. can cause hand tremor, and the dose should be reduced, stopped or changed according to the doctor's instructions.

Parkinson's disease: If you are a middle-aged person in your 50s and have uncontrollable shaking of one side of your hands and feet, and the shaking is noticeable when the limb is stationary and lessens during activity, you should be highly alert to the possibility of Parkinson's disease. The most typical manifestation of the disease is the appearance of the thumb and index finger 3-4 times per second, technically known as "pill-rubbing" movements.

At the same time, the disease can also show a decrease in manifestations with the prolongation of the course of the disease, such as limb stiffness, reduced movement, and unsteady walking.

Essential tremor: In contrast to Parkinson's disease, essential tremor (also known as familial tremor and essential tremor) should be suspected first if you have a similar patient in your family and cite a small amount of alcohol to reduce your tremor.

The causes of hand tremors are divided into four types: physiological, pathological, psychological, and primary. (1) Physiological: Some tremors do not occur in normal times, only in certain situations (such as:

stress, nervousness, and anger), and even drinking coffee, tea, cola and other beverages are physiological tremors. (2) Psychological: hand tremors caused by mental illness, etc.

3) Primary (benign primary tremor): that is, Feng Zai said that we cannot find out exactly what causes the tremors, which may be caused by a special constitution and have a certain genetic predisposition. (4) Pathological:

Refers to tremors caused by nervous system dysfunction, such as Parkinson's disease or Parkinson's disease, as well as metabolic abnormalities such as hypoglycemia or hyperthyroidism.

In general, physiological ones can ignore it and avoid its predisposing factors. But pathological tremors, then ** is needed.

A tremor or tremor in one part of the body is one of the most common movement disorders, and the hands are the part of the body that is most likely to suffer from this pain. In most cases, most of the "hand tremors" we call are non-permanent, often occurring in mental states such as nervousness, fear, excitement, fatigue, etc., which is called "essential tremor", but if it is frequent or even permanent hand tremor, it may be the pathological cause. The cause can be identified based on when and how the tremor appeared.

Hand tremors are seen in physiological hand tremors as well as pathological hand tremors. Symptoms of hand tremor may occur after lifting heavy objects, and symptoms of hand tremor may also occur when stressed. Under pathological conditions, if your hands are shaking due to hunger or low blood sugar, you don't have to worry too much.
