With a tremor (this is what involuntary rhythmic oscillatory movements in various parts of the body are called) of the hands, many have encountered at least once in their lives. Shivering can be caused by a variety of factors, from overwork, excitement, fear, to Parkinson’s disease.
What causes hands to shake
Tremor may be physiological: for example, during exercise, high temperature, smoking, excessive consumption of tea and coffee. Physiological trembling in the hands may appear when taking certain medications – neuroleptics, antiepileptic drugs, antidepressants. Physiological tremor disappears when the causes that cause it are eliminated.
Pathological tremor can be primary (an independent neurological disease) and secondary (develops against the background of serious pathologies). In both cases, the help of a specialist is required.
One of the most common neurological pathologies is essential tremor, a hereditary disease of the nervous system, which is characterized by a slight trembling of the hands that occurs during movement. It may present in young or middle age and worsens over time. Trembling in the hands is noticeable when performing any action (for example, when you need to write or hold an object).
Essential tremor is often confused with Parkinson’s disease. But with it, hand trembling occurs at rest and is accompanied by an increase in muscle tone. Essential tremor is characterized by hand trembling during movement. This disease has one feature – taking small doses of alcohol almost completely removes trembling in the hands. Experts call this feature “alcohol test”.
What does trembling in the hands say?
Pathological trembling in the hands can be a symptom of many serious diseases.
neurological pathologies. Hand tremors are one of the first symptoms of Parkinson’s disease. This progressive neurological disease is more common in older people. At the same time, shaking of the head can join the tremor of the hands over time. With physical exertion, excitement tremor increases. In addition to these symptoms, Parkinson’s disease is accompanied by muscle weakness, depression, memory loss, and mental decline.
Hands can also tremble with damage to the cerebellum as a result of trauma, stroke, encephalitis, and oncology. Major tremors and incoordination usually occur in these conditions.
Autoimmune pathologies. Hand trembling is one of the symptoms of multiple sclerosis. With this disease, tremor occurs in other parts of the body.
Diseases of the cardiovascular system. Most often, trembling is experienced by people suffering from hypertension – this happens with a sharp increase in pressure.
Endocrine pathologies. Tremor often occurs when the thyroid gland produces an excess of thyroid hormones. In this case, trembling in the hands is often accompanied by weight loss, sweating, increased heart rate, muscle weakness, irritability.
Pathologies of the musculoskeletal system. In some cases, osteochondrosis of the cervical spine can lead to the appearance of tremor, and with it numbness of the hands.
Diabetes. In diabetes mellitus, hand trembling occurs against the background of a sharp decrease in blood glucose. With this disease, you can not skip meals, you need to constantly monitor the level of sugar.
Wilson-Konovalov disease. Hand trembling is a companion of one of the forms of a rare hereditary disease, Wilson-Konovalov disease. Its cause is a violation of copper metabolism in the body. It accumulates in the liver, cornea, brain, kidneys and causes their intoxication.
Poisoning. Another reason for the appearance of trembling in the hands is poisoning with toxic substances (carbon monoxide, salts of heavy metals). This condition is a medical emergency.
The treatment regimen for pathological tremor is selected individually and depends on the disease that provoked it. Do not self-diagnose – consult a doctor.
