| Explanation | [[Explanation::This patient is suffering from essential tremor. Essential tremor is a neurological disorder characterized by shaking of hands. The exact incidence is unknown, but it is presumed to be the most common type of tremor and also the most commonly observed movement disorder. Essential tremor might run in families and can be inherited as an autosomal dominant disease. Other potential sources of tremor (excessive caffeine consumption, recreational drug use, medications, hyperthyroidism) should be excluded if possible. The clues to the diagnosis are the bilateral nature of the tremor, its disappearance upon rest and its attenuation with alcohol use.
Educational objective: The two medications that are prescribed most commonly for control of essential tremor symptoms are the anticonvulsant primidone (mysoline) and the beta-blocker propranolol (inderal). |
