Pharmacotherapy for Poststroke Cognitive Impairment and Poststroke Cognitive Impairment With Dementia: A Review

Poststroke cognitive impairment (PSCI) refers to any level of cognitive decline occurring after a stroke, ranging from mild to severe impairments, while PSCI with dementia describes a more severe form where the cognitive decline significantly affects daily functioning and meets the clinical criteria for dementia. PSCI occurs in more than half of individuals who have had a stroke. Despite its high prevalence, the pharmacotherapeutic options for PSCI are limited. Several pharmacotherapeutic options like cholinesterase inhibitors (e.g., donepezil, galantamine, and rivastigmine) and N ‐methyl‐ d ‐aspartate receptor antagonists (e.g., memantine) have shown potential in improving cognitive functions. However, their overall effectiveness remains inconsistent across different studies and patient populations. Newer drugs such as citicoline, cilostazol, and antidepressants have shown promise, but further research is needed to validate their efficacy and safety specifically for PSCI management.
