Direct linkMaas, Anneke P. H. M.; Didden, Robert; Korzilius, Hubert; Curfs, Leopold M. G. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2012
The prevalence of sleep problems in individuals with intellectual disability (ID) seems to vary between genetic syndromes associated with ID. Different types of sleep disturbances may indicate underlying causes of sleep problems and these types of sleep disturbances may vary between different genetic syndromes. We examined and compared five types…

Maas, Anneke P. H. M.; Didden, Robert; Korzilius, Hubert; Braam, Wiebe; Collin, Philippe; Smits, Marcel G.; Curfs, Leopold M. G. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
We examined the psychometric properties of one part of the Sleep Questionnaire developed by Simonds and Parraga (SQ-SP; 1982), a questionnaire that is frequently used to explore sleep problems and behaviors related to sleep in individuals with intellectual disability (ID). The SQ-SP was completed for 345 individuals with ID (sleep clinic n = 146;…

Braam, W.; van Geijlswijk, I.; Keijzer, Henry; Smits, Marcel G.; Didden, Robert; Curfs, Leopold M. G. – Journal of Intellectual Disability Research, 2010
Background: In some of our patients with intellectual disability (ID) and sleep problems, the initial good response to melatonin disappeared within a few weeks after starting treatment, while the good response returned only after considerable dose reduction. The cause for this loss of response to melatonin is yet unknown. We hypothesise that this…

Braam, Wiebe; Smits, Marcel G.; Didden, Robert; Korzilius, Hubert; van Geijlswijk, Ingeborg M.; Curfs, Leopold M. G. – Developmental Medicine & Child Neurology, 2009
Recent meta-analyses on melatonin has raised doubts as to whether melatonin is effective in treating sleep problems in people without intellectual disabilities. This is in contrast to results of several trials on melatonin in treating sleep problems in individuals with intellectual disabilities. To investigate the efficacy of melatonin in treating…

Maas, Anneke P. H. M.; Didden, Robert; Bouts, Lex; Smits, Marcel G.; Curfs, Leopold M. G. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2009
Individuals with Prader-Willi syndrome (PWS) are at risk for excessive daytime sleepiness (EDS) and disruptive behavior. This pilot study explores temporal characteristics of EDS and severe disruptive behavior across time of day and day of week in seven individuals with PWS (aged between 33 and 49 years) of whom five were matched to controls.…

Didden, Robert; de Moor, Jan M. H.; Korzilius, Hubert – Research in Developmental Disabilities: A Multidisciplinary Journal, 2009
Children with epilepsy are at risk for problems in daytime functioning. We assessed daytime sleepiness, on-task behavior and attention in 17 children (aged between 7 and 11 years) with epilepsy who visited a school for special education and compared these to 17 children from a control group who visited a regular school. Within the group of…

Peer reviewedDidden, Robert; De Moor, Jan; Kruit, Inge Wichink – International Journal of Disability, Development and Education, 1999
A case study assessed the efficacy of extinction of parental attention on nighttime crying of a 2-year-old Dutch child with a physical disability. Parents of the child were instructed to ignore nighttime crying. Extinction of parental attention was effective in the elimination and long-term maintenance of nighttime crying. (Author/CR)

Didden, Robert; Korzilius, Hubert; Smits, Marcel G.; Curfs, Leopold M. G. – American Journal on Mental Retardation, 2004
Prevalence of severe sleep problems and its association with other variables were investigated with 109 individuals who have Angelman syndrome. Severe settling problems, frequent night waking, and early waking were found in 2%, 37%, and 10% of the individuals, respectively. Sleep problems were persistent in this sample. No statistically…
