Tremor, or Why Your Hands Shake

Tremor is a shaking of the body or its individual parts, which can be both a physiological sign and a symptom of certain diseases of the nervous system. In this article we will look at the different types of tremors and their causes.

Benign tremor

Benign tremor, also known as familial, senile or juvenile tremor, is the most common movement disorder. It does not have any apparent cause and can manifest itself in the form of trembling of the hands, head, tongue and other parts of the body. It is possible that the person will have difficulty holding objects as well as speaking. The tremor increases with excitement and alcohol consumption. Usually no treatment is needed for this type of tremors, but if the shaking is significant, your doctor may prescribe medications such as propranolol or primidone.

Postural tremor

Postural tremor can be benign in nature and be a manifestation of heredity, increased anxiety, thyroid disease, and also be caused by withdrawal symptoms when taking alcohol or drugs. This type of tremor is always small-scale and is better noticeable when a person stretches out his arms and spreads his fingers. Does not disappear with movement, intensifies with concentration. Treatment is usually prescribed depending on the cause of the tremor.

Intention tremor

Intention tremor occurs when the cerebellum, which is responsible for balance when walking, is damaged. It is characterized by rough, large-scale movements that are absent at rest and appear during targeted movements, especially at the end. The patient cannot reach his nose from a standing position with outstretched arms and closed eyes.

Asterixis

The greatest concern is a type of tremor called asterixis, which can be a symptom of diseases such as Wilson-Konovalov disease, liver, respiratory or renal failure, or damage to the midbrain. The movements with it resemble the flapping of wings - this is a slow, irregular flexion and extension of the limbs.

Parkinson's disease

Parkinson's disease is a disease of the nervous system that is often accompanied by tremors. It usually develops in older people and can manifest as difficulty coordinating movements, slowness of movement, muscle stiffness and tremors at rest. Tremors in Parkinson's disease usually begin in one arm and spread to other parts of the body over time. Treatment for this disease includes medications, physical rehabilitation, and, in some cases, surgery.

conclusions

Tremor is a disorder of the nervous system that can be both a physiological sign and a symptom of certain diseases. Types of tremors can vary in causes, symptoms, and treatment. If you experience body tremors or notice other symptoms related to the nervous system, seek medical advice. It is important to get a diagnosis and prescribe the correct treatment to avoid worsening the condition and developing complications.
