What disease does the index finger tremor indicate?

In daily life, many people experience shaking hands, which may be caused by tension or illness, so it is particularly important to understand the relevant knowledge. Many people do not understand what disease the trembling of the index finger is a harbinger of. In fact, this needs to be judged based on the condition of people's trembling. Patients with different diseases need different treatments. Friends who experience related symptoms need to seek medical examination and treatment in time.

1 Hand tremors are divided into intentional tremors and involuntary tremors. The former occurs when performing movements and affects motor function; the latter only exists when the person is still and does not affect motor function. The former is a problem with the cerebellum and vestibular function, while the latter may indicate hyperthyroidism. Of course, some normal people may also have mild tremors. As long as it does not affect the function, just leave it alone.

Guidance: To check for tremors, hold your hands forward with the backs of your hands facing upwards, place a piece of paper on top of them, close your eyes, and see if the paper vibrates. If the tremor is severe, it is recommended to go to the hospital for a neurological examination. Common diseases that cause hand tremors include upper limb nerve diseases and injuries, brain tissue diseases and drug poisoning, Parkinson's syndrome, cerebral atrophy, hepatic encephalopathy, etc. You should promptly seek appropriate examinations from a neurologist, endocrinologist, and metabolist to identify the cause and receive correct treatment.

2 Physiological hand tremors have small amplitude and fast speed, and occur when one is under mental tension, fear, emotional excitement, severe pain, and extreme fatigue. Pathological tremor refers to involuntary shaking of the hands. Static tremor occurs when the muscles are completely relaxed and disappears during sleep. Typical diseases include Parkinson's syndrome. The other is motor tremor, which only occurs during exercise.

Guidance:

It is recommended to go to the hospital and ask the doctor to do a finger-nose test, that is, straighten your forearm and point your index finger at the tip of your nose. If the tip of the index finger is closer to the tip of the nose, the more obvious the hand tremor is, it is pathological hand tremor. If there is no such phenomenon, the diagnosis can be considered as motor tremor, which is mainly enhanced by emotions, and the diagnosis of cranial nerve or upper limb neuropathy can be considered.

3. The tremors in adolescent hands may be primary tremors, which are tremors that occur when the hands are in action (such as holding chopsticks, picking up food, writing, etc.). This type of tremor can be further divided into postural and intentional tremors. The most common action tremor is primary tremor, which usually starts with one hand, and gradually the other hand will also tremble, and it becomes more serious with age. About 0.3% to 1.7% of people have this kind of tremor, so it is very common. About half of them are inherited, which is autologous dominant inheritance. The age of onset is about 15 years old. The incidence rate of men and women is the same. Sometimes even the head, neck, face, chin and vocal cords will tremble. If the action tremor is not serious and does not affect life or work, no medication is needed. Usually, when patients come to the clinic, they say that the tremor is serious enough to affect their daily life functions, but when asked how long they have been ill, they often don’t know.

Guidance: If it reaches this stage, taking medication (such as beta-blockers or certain anti-epileptic drugs) can control the condition. Interestingly, some hand tremors may temporarily slow down or disappear after drinking alcohol. The clinical cause is Parkinson's syndrome.
