Whether memory loss after cerebral infarction can be recovered is closely related to the site and extent of cerebral infarction injury, and whether the treatment is timely for post-rehabilitation training. 1. Possible recovery: if the scope of cerebral infarction is small and the injury site is non-memory nerve function area, memory will not be damaged after active treatment. After active treatment, memory is not damaged. With conscious functional practice in the later stage, memory can basically be recovered. 2. Difficult to recover: If the scope of cerebral infarction is large or the damaged area affects the area of hippocampus in the medial temporal lobe of the brain, the internal capsule, the thalamus and other areas, and if it is not diagnosed in time and misses the golden period of salvation, then memory loss may occur, and the recovery is relatively slow. However, by controlling the risk factors of the underlying disease, improving microcirculation, giving oral cognitive improvement drugs such as donepezil and carboplatin when necessary, and strengthening cognitive rehabilitation training at a later stage, it is possible to achieve the stimulation of brain cells and improvement of memory. Memory loss caused by cerebral infarction is recommended to go to the hospital for rehabilitation in time.
