First, obtain a much more thorough sleep history (from pt and bed partner), medical history and medication list. I am particularly interested whether he has any abnl movements during the day such as RLS sxs, dystonias, tremors or a seizure disorder - as well as all of the other usual sleep and medical questions.
Second, would perform a diagnostic PSG with an extended EEG montage (12-16 leads), video recording of PSG, and also extra limb leads.
