Drop episodes in Coffin-Lowry syndrome: an unusual type of startle response.
We present a patient with a complete Coffin-Lowry syndrome, associated with drop episodes precipitated by sudden auditory stimuli, which provoked in turn, a definite loss of muscle tone in both legs. Electrophysiological studies showed that these episodes are an unusual type of startle response and that they may be associated with Coffin-Lowry syndrome.
