The trembling of the body (tremor) is a violent vibrational movement that covers the entire body or its parts as a result of repeated contractions and relaxation of the muscles. Muscle contractions are rhythmic, the frequency of oscillatory movements is 2-15 per second. The amplitude of tremor is large, medium and small. In addition, tremor can be physiological and pathological. The latter is most often a sign of damage to the central nervous system. With age, the severity of one of the forms of pathological tremor - an essential tremor - is amplified. Tremor is characteristic of Parkinson's disease. In a healthy person, postural tremor is possible, manifested by maintaining a certain posture of the body (eg, by raising the arms upwards and holding them for a long time in this position). Such a tremor, as well as a weakly expressed senile tremor, is not considered a deviation. For all types of tremor is characteristic that the patient can not affect it - shaking does not depend on the will of man, they can not be controlled.
Possible causes of jitter
The causes of body trembling are manifold, so the doctor should be engaged in their detection.
Fear. With a strong fright or excitement, so-called. Psychogenic tremor, usually accompanied by a strong palpitation. When a person calms down, the trembling stops.
Fatigue. Trembling occurs with severe fatigue.
Chills. The trembling of the muscles of the whole body, accompanied by a feeling of cold, indicates an increase in body temperature. This condition is called chill.
Alcohol abuse. Usually, the tremor manifests after taking a lot of alcohol. Such tremor is a sign of chronic alcoholism.
Strengthening the function of the thyroid gland. Trembling occurs with an excess of thyroid hormones. There are rapid heartbeats, increased sweating, diarrhea, exophthalmos. However, similar symptoms can be observed in other diseases.
Vegetative dystonia. Trembling is a common symptom of vegetative dystonia (dysfunction of the autonomic nervous system, characterized by headache, dizziness, frequent blinking, noise in the ears, increased sweating and pains in the stomach).
The defeat of the cerebellum. The defeat of the cerebellum is characterized by the appearance of a tremor when the patient performs certain precise motor acts.
Parkinson's disease. For Parkinson's disease and parkinsonism, jitter occurs in the patient at rest. As soon as a person starts moving, the trembling disappears.
Poisoning. Trembling of the body is observed with various poisonings, for example, lead or mercury (mercury tremor). The reason for this tremor is severe dysfunction of the central nervous system.
Diseases of the central nervous system. The trembling of the body can also be a symptom of certain diseases of the central nervous system. Due to the variety of diseases of the central nervous system, only a qualified doctor can make an accurate diagnosis.
