RT Journal Article SR Electronic T1 Beta blockade in lithium tremor. JF Journal of Neurology, Neurosurgery & Psychiatry JO J Neurol Neurosurg Psychiatry FD BMJ Publishing Group Ltd SP 719 OP 721 DO 10.1136/jnnp.38.7.719 VO 38 IS 7 A1 Kellett, J M A1 Metcalfe, M A1 Bailey, J A1 Coppen, A J YR 1975 UL http://jnnp.bmj.com/content/38/7/719.abstract AB Practolol, propranolol, and placebo have been tested on an objective test of lithium induced tremor. Both beta-blocking agents produced significantly more tremor than the placebo. It is argued that lithium induced tremor is closer to essential than to physiological tremor.
