Sleep problems in adults with learning disabilities: the compelling need for objective and methodologically consistent studies

Context Literature has consistently reported a high frequency of sleep disorders or sleep alterations in adults with learning disabilities (8.5%–34.1%), ranging from difficulties in falling asleep to sleep loss, daytime sleepiness or altered sleep behaviours. A few studies clearly stated the criteria for defining the presence of sleep problems in this population. Further, there is substantial methodological heterogeneity in the current research. The systematic review by Shanahan et al has a twofold purpose. On the one hand, it aims to describe studies investigating sleep disturbance in adults with learning disabilities. On the other hand, it provides the actual prevalence of disordered sleep and sleep disorders in this population.
