What is missing from hand tremors?

Sometimes when we feel very bored, we will shake our legs and hands to pass the time. However, many of our friends have this habit in life. Not only do they shake their legs and hands when they are working, but they also do so when they eat and sleep at home. If you encounter such a situation, you can actually go to the hospital for a check-up. It may be a sign of illness. So, what is missing from hand shaking?

Physiological hand tremors have small amplitudes and fast speeds, and often occur when the hand is stationary. They are small, fast, and irregular tremors. Physiological hand tremors often occur when one is under mental stress, fear, emotional excitement, severe pain, or extreme fatigue. Once the above causes of hand tremors are eliminated, the hand tremors will also disappear.

Pathological hand tremor, medically known as "tremor", refers to involuntary tremors of the hands, which are often permanent. There are two main types of hand tremors: static hand tremors and dynamic hand tremors. Among them, static hand tremor is the hand tremor that occurs when the muscles are completely relaxed, that is, in a quiet state. This type of hand tremor disappears during sleep, with a frequency of 4-6 times per second and a relatively regular pattern. It is a typical disease such as Parkinson's syndrome. Sports tremor is a tremor that only occurs during exercise, and the tremor becomes more severe when the movement approaches the target. For example, when a doctor performs the finger-to-nose test on a patient, he asks the patient to straighten his forearm and then point his index finger at the tip of his nose. The closer the tip of the index finger is to the tip of the nose, the more obvious the hand tremor will be. Motor tremors are irregular, with large amplitudes, and are aggravated by emotions. They are common in lesions of the cranial nerves and upper limb nerves.

Common diseases that cause pathological hand tremors clinically include upper limb nerve diseases and injuries, brain tissue diseases, and drug-induced hand tremors.

Hand tremors are common among the elderly. The constant shaking of both hands has seriously affected eating and writing, which makes the elderly very distressed. Medically, this shaking is called tremor. Although tremor manifests as shaking of the hands, the root cause is mostly in the anterior cruciate lateral lobes. Due to certain diseases, the area of ​​the anterior cruciate lateral lobes responsible for motor coordination is damaged, causing tremor.

Clinically, Parkinson's disease, cerebral arteriosclerosis, midbrain or cerebellar lesions, hepatic encephalopathy, drug poisoning, dementia, etc. may all cause hand tremors in the elderly. Medical research has found that eating broad beans and coffee can effectively control tremors. Family members can appropriately feed the elderly more of these two foods.

If pathological factors are excluded, another common cause of hand tremors is psychological factors.

Your problem is a bit like anticipatory anxiety. This type of question often creates a situation that the patient feels frightened about. For example, you may be very worried that your hands will shake when other people are around you at work, and then when someone comes in front of you, your hands actually shake. In anticipatory anxiety disorder, anxiety about symptoms that cause a psychological response can exacerbate or lead to the onset of symptoms. The onset of symptoms further intensifies anticipatory anxiety, thus forming a vicious cycle. You are trapped in this vicious cycle and cannot extricate yourself.
