Why They Cause Drooling:
These disorders can weaken or delay the swallowing reflex, so saliva builds up in the mouth and spills out during sleep — even if you’re producing a normal amount.
Other Symptoms:
Tremors or muscle stiffness
Slurred speech
Difficulty chewing or swallowing (dysphagia)
Facial weakness or drooping
Unexplained weight loss
What to Do:
If you notice drooling along with any neurological symptoms, consult a neurologist. Early diagnosis can lead to better management and improved quality of life.
