POST-STROKE COGNITIVE IMPAIRMENTS IN DIFFERENT PATHOGENETIC SUBTYPES OF STROKE: A REVIEW.
Keywords:
stroke, cognitive impairment, ischemic stroke, hemorrhagic stroke, pathogenesis, rehabilitation.Abstract
Post-stroke cognitive impairments (PSCI) are one of the most significant complications in modern neurology, substantially affecting patients’ quality of life and recovery prognosis. The prevalence of cognitive deficits after stroke ranges from 30% to 80%, depending on stroke subtype, lesion location, and concomitant vascular pathology. This review discusses the mechanisms of PSCI in ischemic and hemorrhagic strokes, as well as in different pathogenetic subtypes of ischemic stroke: atherothrombotic, cardioembolic, lacunar, and mixed types. Special attention is given to structural and functional brain changes associated with impairments in memory, executive functions, attention, and language skills. The review emphasizes the importance of early diagnosis, individualized rehabilitation, and the potential use of neuroprotective therapies.
