Essential tremor is one of the most common movement disorders. It is characterized by rhythmic involuntary tremors that typically occur in the hands, arms, head, or vocal cords.
The most prominent symptom of essential tremor is involuntary tremors. These tremors often affect the hands, especially the fingers, and become more pronounced when the hands are holding something or performing a task. Tremors may also occur in other areas such as the arms, head, jaw, or vocal cords. They typically occur during movement, diminish at rest, or disappear completely.
The exact cause of essential tremor is unknown, but it is believed to involve a combination of genetic and environmental factors. Genetic predisposition has been observed in some families, and specific gene mutations have been associated with the condition. Additionally, environmental factors such as stress, fatigue, caffeine, and certain medications are thought to trigger tremor symptoms.
Treatment for essential tremor is available. The goal of treatment is to reduce the severity of symptoms and improve the patient's quality of life. Medications are commonly used treatment methods. Drugs such as beta-blockers, anticonvulsants, or antidepressants may be effective in reducing tremors. In addition, surgical or specialized treatment options such as botulinum toxin injections or deep brain stimulation may be considered for some patients.
Essential tremor is generally not a progressive disease and does not threaten life. However, symptoms may worsen over time and affect daily life activities. Since symptom control is often achievable with treatment, most patients can maintain a good quality of life. However, in some cases, symptoms may be resistant to treatment and further impact quality of life.
