Abstract Three patients with clinically proved subacute sclerosing panencephalitis (SSPE) had electroencephalograms in which periodic stereotyped complexes characteristic of SSPE were apparent during sleep but were not observed during the initial awake recordings. The first patient had periodic complexes only during sleep. The second and third patients had complexes that were inconstant and sporadic during the awake recordings but regular and periodic during sleep. Although sleep can have a variable effect on the electroencephalographic pattern in SSPE, it may facilitate elicitation of typical periodic complexes in questionable cases of SSPE.
