Description
Hamza Adel Salim and a large team link delayed venous drainage on brain scans to early thinking problems after stroke in a 2026 study. Two hundred fifty-three patients with large vessel blockage in the front circulation had perfusion imaging at arrival. Each also received a four-item cognitive score at discharge. That score was built from standard stroke scale items covering orientation, commands, language and attention. Prolonged venous transit meant a marked delay in two deep drainage points on the scan.
About one third of patients showed the delay, and their discharge cognitive scores were notably worse. The link held after adjusting for age, stroke severity, side and final damage volume. A combined model separated normal from impaired cognition well. Venous health may add prognostic information beyond clot and tissue measures.
