Do you know what it's like to shake hands often involuntarily? When it comes to finger trembling, many people may think of Parkinson's disease first. In fact, the first symptom of Parkinson's disease is tremor, and most patients with Parkinson's disease have tremor. Hand tremor can be divided into two categories: physiological hand tremor and pathological hand tremor. Physiological hand tremors can also occur at rest, but the tremors are small and fast, which mostly occur in the case of mental tension, emotional excitement and extreme fatigue. Once these factors disappear, hand tremors will also disappear. Pathological tremor refers to the permanent tremor of the hand, which is medically called "tremor".

What disease can finger trembling mean? In daily life, Parkinson's disease is one of the factors that cause physiological finger trembling, but incomplete physiological finger trembling is caused by Parkinson's disease. In other words, your hands are shaking, which is usually a sign that you are ill. There are many diseases related to hand tremor, which means that the actual diseases can only be understood according to medical diagnosis.

So, what is the reason for hand shaking? Hand tremors may be caused by the following symptoms. 1. Parkinson's disease

Hand shaking is a prominent symptom of Parkinson's disease. When the patient's hands, hands and feet have uncontrollable abnormal tremor. This tremor will become more and more obvious when the body is at rest, and will be relieved when exercising, so be careful of the probability of Parkinson's disease.

Parkinson's disease has another obvious main manifestation. Thumb and ring finger will make 3-4 coordinated gestures every second, just like "rubbing the ball". Don't be careless about such common main manifestations.

2. Primary tremor leads to finger trembling.

Arm tremor may also be a major sign of primary tremor. As we all know, this kind of primary finger tremor is just the opposite of Parkinson's disease. Tremor is obvious when the limbs move, and it is relieved or subsided when the body is still. Especially when doing some physical exercise, the hand tremor will be very obvious. Everyone should be careful when this tremor occurs, which is a major manifestation of primary tremor.

3. Hyperthyroidism

Hyperthyroidism is also called hyperthyroidism, and tremor is the main manifestation of hyperthyroidism. Your hands are shaking, accompanied by classic hyperthyroidism symptoms, such as sweating, overeating, weight loss and so on. You must be careful of hyperthyroidism. Hyperthyroidism is very harmful to human body. Once the above symptoms appear, it is best to go to a medical institution for corresponding examination as soon as possible.

4. The patient's thalamus is sick.

Finger trembling is sometimes closely related to the occupation of cerebellar lesions in patients. Hand tremor caused by cerebellar lesions has a certain purpose, and the closer the patient is to the overall goal, the more obvious the hand tremor will be. The patient will also have nystagmus and unstable standing. You have the above main manifestations, so you must be careful of cerebellar lesions.
