The main causes of transient memory loss in the elderly are as follows: 1. Concussion, elderly people may suffer from concussion after head trauma, and concussion can cause transient retrograde amnesia in the elderly. 2. Seizures, patients with full-blown seizures and complex partial seizures can experience transient memory loss lasting about a few minutes, and memory can return to normal after the seizure subsides. 3. Transient cerebral ischemia Seizures, posterior circulation transient cerebral ischemic seizures are mostly seen in elderly patients, who may experience transient memory loss, dizziness, tinnitus and other symptoms, which can generally be recovered within 24 hours. 4, acute ischemic-hypoxic encephalopathy, plateaus, confined spaces and other environments as well as acute myocardial ischemia can lead to ischemia and hypoxia in elderly people, who may also experience transient memory loss, headache and other symptoms. The patient’s symptoms can be relieved by improving the environment, oxygenation and other symptomatic treatments.
