Memory-enhancing drugs can be applied to olanzapine, piracetam and cytidylcholine. Memory loss can be caused by a variety of diseases, for example, it can occur in patients with encephalitis, and memory impairment may occur after treatment of cerebrovascular disease, massive cerebral infarction and cerebral hemorrhage. It can also be caused by severe hypertension, which can cause hypertensive encephalopathy in severe cases. Patients mainly show memory loss, and in severe cases, they may have impaired consciousness, which can be manifested as blurred consciousness. If the patient is in the early stage of Alzheimer’s disease, memory loss may also occur. As the disease progresses, cognitive dysfunction may occur, or complete loss of cognitive function may occur, and patients in the late stage may develop intellectual impairment, which can be treated with oral donepezil or staphylococcus aureus. It may also be caused by chronic cerebral blood supply deficiency. When caused by the above factors, the main treatment is to improve blood circulation, and Cipro and Ginkgo biloba drops can be taken orally.
