Actigraphic investigation of circadian rhythm functioning and activity levels in children with mucopolysaccharidosis type III (Sanfilippo syndrome) / R. A. MUMFORD in Journal of Neurodevelopmental Disorders, 7-1 (December 2015)
[article]
Titre : Actigraphic investigation of circadian rhythm functioning and activity levels in children with mucopolysaccharidosis type III (Sanfilippo syndrome) Type de document : Texte imprimé et/ou numérique Auteurs : R. A. MUMFORD, Auteur ; L. V. MAHON, Auteur ; S. JONES, Auteur ; B. BIGGER, Auteur ; M. CANAL, Auteur ; D. J. HARE, Auteur Article en page(s) : p.31 Langues : Anglais (eng) Mots-clés : Actigraphy Circadian rhythms Mucopolysaccharidosis type III Sanfilippo Sleep Index. décimale : PER Périodiques Résumé : BACKGROUND: Sleep disturbance is part of the behavioural phenotype of the rare genetic condition mucopolysaccharidosis (MPS) type III. A growing body of evidence suggests that underlying disturbance in circadian rhythm functioning may explain sleep problems within the MPS III population. METHODS: Actigraphic data were recorded in eight children with MPS III over 7-10 days and compared to age-matched typically developing controls. Parameters of circadian rhythmicity and activity levels across a 24-h period were analysed. RESULTS: Statistically and clinically significant differences between the two groups were noted. Analysis indicated that children with MPS III showed significantly increased fragmentation of circadian rhythm and reduced stability with external cues (zeitgebers), compared to controls. Average times of activity onset and offset were indicative of a phase delayed sleep-wake cycle for some children in the MPS III group. Children with MPS III had significantly higher activity levels during the early morning hours (midnight-6 am) compared to controls. CONCLUSIONS: Results are consistent with previous research into MPS III and suggest that there is an impairment in circadian rhythm functioning in children with this condition. Implications for clinical practice and the management of sleep difficulties are discussed.
