Brain susceptibility to poststroke cognitive impairment and dementia - Genetic susceptibility - Cerebral reserve - Preexisting brain pathology (AD/ADRD, SVD, BBB-P) - Stroke - Acute lesion impact (subtype, size, topography) - Acute Rx and rehab - Poststroke cognitive and functional outcomes - Mechanisms of brain resilience - Lifetime environmental exposures, vascular risk and sociodemographic factors
  • Post-stroke cognitive impairment (PSCI) ranges in severity from mild to severe and occurs in up to 60% of stroke survivors in the first year after stroke, with a higher rate seen acutely after stroke.
  • The risk of developing future dementia increases after stroke, even in those with transient cognitive impairment.
  • This statement discusses many aspects of PSCI with thoughtful discussions about recognition, diagnosis, and treatment of this post stroke condition.
