There is no quick cure for poor memory. Poor memory is mostly caused by long-term sleep deprivation, cerebral arteriosclerosis, and cerebral white matter degeneration. It can be improved and treated by keeping enough sleep, taking ginkgo biloba tablets, olanzapine and other medicines. 1. Long-term sleep deprivation: Long-term sleep deprivation will lead to memory loss, and it is necessary to maintain sufficient sleep and improve lifestyle. 2. Cerebral arteriosclerosis: Cerebral arteriosclerosis leads to insufficient blood supply to the brain, so memory loss can occur, and can take brain protein extract tablets, ginkgo biloba tablets and other drugs for treatment. 3. Cerebral white matter degeneration: Cerebral white matter degeneration will lead to poor memory, so you can choose drugs such as Oracetam and sodium cytosine to improve memory problems. When poor memory occurs, you should go to the hospital in time to clarify the specific cause of the disease and treat according to the doctor’s advice.
