Definition of Tremors

Tremors are unintentional muscle or body part movements that are similar to oscillations. It is an involuntary movement that can be made by hands, legs, head, vocal chords, face and other parts of the body. The most common tremor is seen in the hands of a person. Sometimes chattering of teeth due to fear is also a tremor. Tremors are symptoms of a neurological disorder in a human. Tremors are of different types. Some of the types of tremors are essential tremor, dystonic tremor, Cerebellar tremor, psychogenic tremor and many more.

These tremors occur due to disorders in the parts of the brain that control the movements of the rest of the body like the arms and the legs. These disorders in the brain can be caused by many diseases like stroke, multiple sclerosis and brain injury. These diseases damage the brain’s stem cells and affect the cerebellum. Sometimes certain drugs can also cause a tremor in the body. Some of these drugs are caffeine, amphetamines and selective serotonin reuptake inhibitor SSRI. Tremors do not have any age factors and can occur at any age. They can occur for a temporary period of time or intermittently.

The essential tremor which is a type of tremor is also known as benign essential tremor. It is the most common tremor and can occur to anybody. It is one of the mild tremors which do not affect the body in a very great manner. However, if their severity is increased by stress, fear, exhaustion or low blood sugar, it may have severe consequences on the body. Though it is common to people in the age of 40 and above, it can be found in people of any age and gender.

The second type of tremor which is also known as dystonic tremor is found in people who are affected by the disease called dystonia. Dystonia is a disorder that occurs in people due to repetitive contractions and twisting motions. This can be identified when a patient holds himself in a certain position or posture. This tremor is very irregular with its pattern. It can be relieved by touching the respective body part that has been affected by the tremor. This type of tremor can also be taken as a symptom for dystonia.

The third type called the cerebellar tremor is also known as intention tremor. It is a slow and broad tremor with great extremities. This tremor occurs when a person purposefully moves the body. This tremor is actually caused by the damage of the lesions in the cerebellum of the brain. Tremors can be treated through medication, surgery and by changing the lifestyle of a person. All these methods help a person to recover completely from any kind of tremor.
