Causes of hand tremors

Some people often find that their hands are shaking in life and work. In fact, there are only two reasons for hand shaking. One is a psychological problem. If there is psychological tension, it will cause hand shaking. The second is the pathological cause, which is Parkinson's disease that we often hear about. This disease is caused by the degeneration of the elderly's body.

If the hand tremors are caused by psychological problems, they can be solved by relieving your emotions. If that doesn't work, you should go to a psychologist for consultation and treatment. If an elderly person experiences hand tremors, he or she should be checked promptly.

Pathological factors

1. Essential tremor. The cause of this disease is unknown and it mainly affects the upper limbs and head. The main symptom is hand tremors when doing fine movements, such as writing, holding chopsticks, buttoning, etc. Hand tremors are more obvious when you are emotionally nervous or tired, and they are reduced or disappear completely when you relax or rest. Symptoms may be alleviated after drinking alcohol. Neurological examination showed no abnormalities except hand tremors. Currently, the most effective treatment for this disease is drug therapy. Taking medicine can improve symptoms, but they will relapse after stopping the medicine, which is the so-called "treating the symptoms but not the root cause." Essential tremor progresses very slowly or not at all and has little effect on daily life.

2. Parkinson's disease. This is a degenerative disease that occurs in the elderly. In addition to hand tremors, it is also accompanied by symptoms such as slow movements, limb stiffness, and poor balance. If not treated, symptoms will become more severe. This disease requires the help of a specialist to diagnose and treat.

Psychological factors

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

Anticipatory anxiety disorder Anticipatory anxiety disorder. 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. From this we can see that what the patient is really afraid of is fear itself.

Symptom classification

Hand tremors can be divided into physiological tremors and pathological tremors based on symptoms.

Physiological hand tremor

The amplitude is small and the speed is fast. It mostly occurs when the machine is stationary. It is a small, fast and irregular vibration. 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", it 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 tremors appear as shaking hands, the root cause is mostly in the brain. Tremors are caused by certain diseases that damage the area of ​​the brain responsible for motor coordination. 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.

The above is an introduction to the causes of hand tremors. I believe that after reading this, you will have a clearer understanding of hand tremors. Many people think that hand tremors are definitely Parkinson's disease. In fact, this is not the case. Many times, they are caused by psychological factors, so psychological adjustments are very important.
