Sialorrhea / etiology

Sialorrhea is common in children with neurologic impairment

Sialorrhea can be normal in children with typical development until age 4 years. It occurs in as many as 44% of children with cerebral palsy.1 It typically results from poor oral motor control and fluctuates alongside the child’s developmental trajectory. Reversible contributors such as nasal obstruction, dental issues, and medication effects (e.g., benzodiazepines and clozapine) should be considered.
