HENRIQUES FILHO, Paulo Sérgio Azeredo  and  PRATESI, Riccardo. Sleep disorder: a possible cause of attention deficit in children and adolescents with Chiari malformation type II. Arq. Neuro-Psiquiatr. [online]. 2009, vol.67, n.1, pp. 29-34. ISSN 0004-282X.  http://dx.doi.org/10.1590/S0004-282X2009000100008.

BACKGROUND: Attention deficit may be related to sleep disorders in Chiari malformation type II (CMII). Our aim is identify sleep disorders and their specific contribution in attention deficit. METHOD: We selected 24 patients with CM II and 24 without CM II. DSM-IV criteria and a neuropsychological analysis were applied in all. All patients underwent full night polysomnography. RESULTS: 14 CM II patients presented sleep apnea syndrome, REM sleep behavior disorder and periodic limb movement in sleep; six patients without CM II presented sleep apnea syndrome. Among these patients, 12 (six with CM II and six without CM II) presented attention deficit related to the sleep disorders. CONCLUSION: Sleep disorders may impair cognitive functions, as attention, and contribute to poor quality of learning also in patients with CM II.

Keywords : polysomnography; REM sleep behavior disorder; apnea; cognition; attention deficit disorder.
