Why do I feel my hands are shaking?

Hand tremors are very common. For example, when we use our hands to do heavy physical labor, our hands will naturally feel very tired over time, so we can't help but have hand tremors. Of course, hand tremors may also be pathological, that is, caused by a certain disease. So, what is the reason for the shaking of hands and what disease is it related to?

Clinically, hand tremor is divided into: rest tremor, kinesiology tremor, postural tremor, rebound tremor and vibration tremor. Although tremor manifests as shaking of the hands, its root cause is mostly in the brain, caused by some disease that damages the area of ​​the brain involved in motor coordination functions. The clinical causes include Parkinson's syndrome, Wilson's disease, hepatic encephalopathy, cerebellar and brainstem lesions, cerebral arteriosclerosis, cerebral ischemia, drug poisoning, dementia, etc. Like the hand tremor attack of the eldest brother of the Rong family in the TV show, judging from the time, place, age and inducing factors, it is very likely caused by his existing senile hypertension, arteriosclerosis, and sudden mental stimulation.

Generally speaking, hand tremor symptoms often occur in the elderly. You should promptly seek appropriate examinations from a neurologist, endocrinologist, and metabolist to identify the cause and provide correct treatment.

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. 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.
