No structural or other lesions have been identified. No other tests may be required. However, testing may rule out other causes of tremors such as excessive caffeine , alcohol withdrawal , medication use, hyperthyroidism , pheochromocytoma , or other disorders. Laboratory tests and a head CT scan , MRI , X-rays, or other tests are usually normal if they are performed. Treatment Treatment may not be necessary unless tremors interfere with the patient's ability to perform daily activities.
Medications are variable because of individual responses to medications.
Medications that may reduce tremors include propranolol, Mysoline and other anticonvulsants, and mild tranquilizers. Alcoholic beverages in small quantities may markedly decrease tremors but can lead to alcohol dependence . The mechanism of how alcohol decreases an essential tremor is unknown. An essential tremor is not a dangerous condition but can be annoying and embarrassing. If it is severe, essential tremor can mildly interfere with activities, especially fine motor skills such as writing.
