Essential tremor (ET) is a neurological disorder characterized by involuntary and rhythmic shaking of certain parts of the body, most commonly the hands, but it can also affect the head, voice, arms, and legs. The tremors are typically present during voluntary movement and can worsen with stress or fatigue.
The cause of essential tremor is not fully understood, but it is believed to be a combination of genetic and environmental factors. It can occur at any age, but it is more common in older adults and tends to run in families.
Essential tremor can be diagnosed through a clinical examination by a neurologist, who will assess the severity and frequency of the tremors, as well as rule out other possible causes. Imaging tests such as CT scans or MRI may be used to rule out other neurological conditions.
Treatment for essential tremor may include medications such as beta-blockers, anticonvulsants, or benzodiazepines, which can help reduce tremors. Physical therapy and occupational therapy can also help manage symptoms and improve coordination and muscle strength. In severe cases, surgical options such as deep brain stimulation may be considered.
While essential tremor is not a life-threatening condition, it can significantly affect quality of life, and it may interfere with activities of daily living. Therefore, it is important to seek medical attention if you experience any symptoms of essential tremor.
