Is excess saliva related to Alzheimers disease?

Excess saliva, or hypersalivation, is not commonly recognized as a direct symptom of Alzheimer's disease. However, some individuals with Alzheimer's may experience changes in saliva production due to neurological dysfunction or medication side effects. While hypersalivation can occur in various neurological conditions, it is not specifically linked to Alzheimer's as a hallmark symptom. More research is needed to fully understand any potential connections.
