Involuntary hand twitching

Some middle-aged and elderly people suffer from involuntary twitching of their hands. There are two situations in which this phenomenon occurs: one is physiological and the other is pathological. The physiological ones are easier to understand. They are related to excessive mental tension. For example, fear or excessive excitement can cause hand twitching. If it is a pathological problem, you need to pay attention to it, as it may be related to the nervous system.

Hand tremors are divided into physiological tremors and pathological tremors.

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 middle-aged and elderly people. Both of my hands are shaking constantly, which seriously affects my eating and writing, and is very distressing. 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.

Medical research has found that eating broad beans and coffee can effectively control tremors. You can eat more of these two foods.
