Yawning in the elderly is not necessarily a disease, for example, when the brain is fatigued or sleepy due to lack of sleep, it can lead to yawning actions. If an elderly person yawns frequently in a disease state, it is considered to be a lack of oxygen to the brain due to insufficient blood supply to the brain, which is common after cerebral arteriosclerosis, posterior circulation ischemia, or a large cerebral infarction. In this case, the elderly must be promptly referred to the hospital for relevant examinations to clarify the cause of the disease and then treat it symptomatically. Oxygen inhalation can be given, and drugs that activate blood circulation and improve blood stasis can be used to improve cerebral hypoxia, which can reduce the yawning action of the elderly. Yawning is not scary, what is scary is the disease hidden behind the yawning.
