Drooling, or excessive saliva production, can be caused by several factors. Neurological conditions such as Parkinson's disease, cerebral palsy, and amyotrophic lateral sclerosis (ALS) can lead to drooling, as can certain medications, radiation therapy, or trauma to the head and neck. People with developmental disabilities or those who have had a stroke may also experience drooling. Risk factors for drooling include age, certain medications, and underlying medical conditions such as Parkinson's disease or stroke. Treatment options vary depending on the cause, but may include medications, surgery, or speech therapy.
