Hypersalivation, or ptyalism, is excessive salivation due to overactive saliva glands. The cause can be pain, Zenker's diverticulum
, ulcer, pregnancy
, infectious lesion in the mouth, or cancer
. Chronic hypersalivation can be caused by Parkinson's disease
, neurological trauma, or even rabies. This condition can also frequently be observed in the elderly who exhibit repetitive tongue movement.
