To the Editor: Dr Hobson and colleagues1 confirmed our preliminary finding2
that episodes of sudden sleep are rare in patients with Parkinson disease
(PD). They reported that 16 of 420 patients reported sudden-onset sleep while
driving. Three patients did not experience prodromal drowsiness or warning,
and 2 events put drivers at risk. These numbers are similar to our estimate
of an annual event incidence of 2%.
