Treatment for sialorrhea (excessive saliva) in people with motor neuron disease/amyotrophic lateral sclerosis.

Motor neuron disease (MND), also known as amyotrophic lateral sclerosis (ALS), is a progressive neurodegenerative condition that may cause dysphagia, as well as limb weakness, dysarthria, emotional lability, and respiratory failure. Since normal salivary production is 0.5 L to 1.5 L daily, loss of salivary clearance due to dysphagia leads to salivary pooling and sialorrhea, often resulting in distress and inconvenience to people with MND. This is an update of a review first published in 2011.
