Types of saliva problems

Motor neurone disease (MND) is a progressive and terminal disease that attacks the motor neurones, or nerves, in the brain and spinal cord. Many people with MND will experience problems with saliva control.

The salivary glands produce two different types of secretions: thin, watery saliva and thick mucus.

Phlegm is a thick mucus secreted by the membranes of the respiratory passages. Someone with MND may experience thin, runny saliva that drools out of the mouth, thick tenacious saliva or phlegm. Thick saliva and phlegm can be difficult to clear.

Some people may experience all of these.
