Sleep problems, chronotype, and diurnal preferences in children and adults with spina bifida.

Edelstein K, Cirino PT, Hasher L, Fletcher JM, Dennis M. (2012) Sleep problems, chronotype, and diurnal preferences in children and adults with spina bifida. J Biol Rhythms. 2012 Apr;27(2):172-5.

Spina bifida meningomyelocele (SBM) is a neural tube defect that involves dysraphism of the spinal cord and extensive reorganization of the brain. The authors assessed the relationship between chronotype, diurnal preferences, and sleep problems in individuals with SBM and healthy controls. Although individuals with SBM showed the characteristic decelerating quadratic relationship between age and chronotype, the curve was displaced, peaking at a younger age in controls compared with SBM (23.4 vs. 29.2 years). Groups did not differ in morningness-eveningness preferences. Individuals with SBM endorsed more sleep problems than controls. Further examination of the relationship between entrainment and sleep in SBM is warranted.
