Essential Tremor

Essential tremor is a neurological disorder characterized by a shaking tremor, usually occurring in the upper part of the body, that cannot be attributed to any other neurological disorder. It is the most common generalized tremor and one of the most common neurological conditions in the world. Essential tremor is usually seen as an action tremor, meaning that it appears when an individual performs voluntary movements where the tremor is usually in the hands, arms, head, or voice. Action tremor usually has an alternating pattern – that is, one side of the body may be more affected than the other at times. It may also be seen at rest, meaning that it does not occur when a person is using the affected part of the body but when that part is resting. Essential tremor usually appears in early adulthood, although it can occur at any age. Its severit, y can range from mild to disabling. It can also worsen with age. Common treatments for essential tremor include medications, physical therapy, biofeedback, and, in some cases, surgery. The exact cause of essential tremor is unknown, although some research has found links to genetic factors and ageing. It also appears to be more common in individuals with certain neurological conditions, such as Parkinson’s Disease or dystonia. Other triggers, such as stress or fatigue, seem to temporarily worsen episodes of tremor. Recent research has suggested that essential tremor can be caused by abnormal electrical activity in the cerebellum, the region of the brain that controls balance and fine motor movements. Treatment of essential tremor is usually focused on reducing the symptoms and improving the quality of life of the individual. Exercise can help reduce the tremor, as can relaxation techniques. Many individuals may also benefit from taking medications or nutritional supplements as prescribed by a healthcare provider.
