ABSTRACT
Sleep spindles are an element of the sleep microstructure observed on the EEG during
the NREM sleep phase. Sleep spindles are associated to sleep stability functions as
well as memory consolidation and optimization of different cognitive processes. On
the other hand, Asperger’s syndrome (AS) is a generalized developmental disorder in
which cognitive and sleep disturbances have been described. In this study we analyzed
different characteristics of sleep spindles in a group of children with AS and compared
them with sleep spindles of a group of children with typical development paired by
age; both groups ranged from 6 to 12 years of age and were all male. We observed a
statistically significant decrease in sleep spindles intrinsic frequency in different
brain regions in the AS group in relation to the typical development group. This finding
could be due to immaturity in brain regions related to the integration of sleep spindles;
and this immaturity could be related with cognitive aspects in these patients.
