Many children with cerebral palsy (CP) have difficulty controlling saliva. Drooling varies in severity and can be distressing for the children, families and caregivers. Chronic drooling is referred to as Sialorrhea and occurs as a result of limitations in a person’s ability to control and swallow oral secretions.
"In addition to commonly associated environmental factors, genomic factors may cause cerebral palsy. We performed whole-exome sequencing of 250 parent–offspring trios, and observed enrichment of damaging de novo mutations in cerebral palsy cases."
