Workshop I: Parkinson's disease and sleep--results of the group discussion

The group agreed on the facts that unwanted sleep onset has been observed after non-ergot as well as ergot dopamine agonists, that patients on these drugs need to be warned, that patients who have experienced sleepiness already must not drive a car unless the dosage is lowered and sleepiness has vanished, that a genetic predisposition for narcoleptic cataplexy has to be ruled out, that predictors of so-called sleep attacks need to be explored individually with the help of sleepiness scales and collectively in a careful study, respectively.
