A comment on sleep assessment of children with cerebral palsy: Using validated sleep questionnaire.

Sir,

Went through article entitled “Sleep assessment of children with cerebral palsy (CP): Using validated sleep questionnaire” published in your journal.[1] The authors must be lauded for their effort in dealing with sleep assessment with a sleep questionnaire. However, I feel that the study suffers methodologically in picking up and reporting on certain sleep related problems like for example in assessment of nightmares in young children. Assessing nightmares in healthy children of pre-school age is also a difficult job and it becomes more so in case of children with CP. The best example of this has been provided by the authors themselves in the discussion part of the article. If we look at the discussion, we hardly note a mention of nightmares being reported by other researchers dealing with sleep assessment. The fact that the study is based on a questionnaire makes it difficult to assess nightmares.
