Abstract
Aims: To observe prevalence of sleep disturbance (SD) in cerebral palsy (CP) children in a specific age-group and its correlation with SD in primary caregivers and other associated factors. Materials and Methods: This was a prospective cross-sectional study. SD assessed using Sleep Disturbance Scale for Children (SDSC) in CP children and Pittsburgh Sleep Quality Index (PSQI) in caregivers. Fifty cases of clinically diagnosed CP [27 females, mean age: 107.9 ΁ 29.5 months (range: 78-180 months)] fulfilling criteria were included. Results: Eighteen (36%) children had pathological sleep total score (TS) and Disorders of Initiating and Maintaining Sleep (DIMS) was the commonest SD (n = 25, 50%). All primary caregivers were mothers. Twenty-five (50%) mothers had SD on PSQI scale. DIMS, Disorders of Excessive Somnolence (DES), and TS had significant correlation with PSQI (P < 0.05). Disorders of Arousal (DA) and TS had significant correlation with seizures (P < 0.05) in CP children. Bed-sharing had significant correlation with SD in caregivers (P < 0.001) but not with CP children. No significant correlation was observed between SD in CP and gross motor function (Gross Motor Function Classification System), use of orthoses, and dental caries. Interpretation: Children with CP have underreported significant SD, which negatively impacts caregiver's sleep also. Seizure disorders and medications contribute significantly to SD.
