Is excess saliva related to Alzheimers disease?

Excess saliva, also known as sialorrhea or drooling, can be a symptom of Alzheimer's disease.

As Alzheimer's disease progresses, it can affect the muscles and nerves that control swallowing and saliva production. This can lead to difficulty swallowing, which can cause saliva to accumulate in the mouth and eventually overflow.

Several factors can contribute to excess saliva in people with Alzheimer's disease:

- Difficulty swallowing: As Alzheimer's disease progresses, it can affect the nerves and muscles that control swallowing. This can make it difficult for people to swallow saliva effectively, which can lead to drooling.

- Reduced oral hygiene: People with Alzheimer's disease may experience difficulty brushing their teeth and caring for their oral hygiene. This can lead to a buildup of bacteria and plaque in the mouth, which can contribute to excess saliva.

- Medications: Some medications used to treat Alzheimer's disease, such as cholinesterase inhibitors, can cause side effects including increased saliva production.

- Increased thirst: People with Alzheimer's disease may experience increased thirst, which can lead to them drinking more fluids. This can also contribute to excess saliva.

Excess saliva can have a significant impact on a person's quality of life. It can lead to skin irritation and discomfort, social isolation, and difficulty with communication. If you or a loved one is experiencing excess saliva, talk to your doctor or dentist. They can assess the underlying cause and recommend treatment options.
