Ischemic stroke is one of the common diseases in neurology department. It can not only cause disability in the motor function of stroke survivors， but also cause different degrees and types of cognitive impairment. Post-stroke cognitive impairment（ PSCI） not only has a negligible effect on the quality of life and work ability of stroke survivors， but also is closely related to the prognosis of stroke survivors. This article will refer to relevant research in China and abroad in recent years. The following will be explained one by one： the dynamic evolution of PSCI， the relationship between post-stroke neurological function plasticity and PSCI， the relationship between demographic data and PSCI， the relationship between biochemical markers and PSCI and the relationship between imaging features after ischemic stroke and PSCI.
