Intention tremor is a dyskinetic disorder characterized by a broad, coarse, and low frequency (below 5 Hz) tremor. The amplitude of an intention tremor increases as an extremity approaches the endpoint of deliberate and visually guided movement (hence the name intention tremor). Causes: The most common causes are multiple sclerosis, midbrain trauma, and stroke. Degenerative diseases of the dentate nucleus and cerebellar outflow pathways, severe forms of essential tremor, Wilson's disease, hepatocerebral degeneration, and mercury poisoning may also produce intention tremor. Management: Isoniazid, buspirone hydrochloride, glutethimide, carbamazepine, clonazepam, topiramate, zofran, propranolol and primidone have all seen moderate results in treating intention tremor and can be prescribed treatments.
