• Experimental models and arterial occlusion techniques established controlled focal cerebral ischemia across species, enabling systematic study of infarct development, reperfusion, microvascular dynamics, and barrier function (retro-orbital/ extradural occlusion, transorbital approaches, and hemodynamic manipulations) [6], [16], [17], [14], [12], [18], [19], [20].

• Population-level stroke epidemiology and natural history were investigated through Rochester cohorts and national morbidity studies, tracing incidence, age effects, stroke types, and prognosis, forming baseline expectations for disease burden and recovery trajectories [2], [4], [9], [11], [10], [8].

• Cerebral hemodynamics and vascular pathology are core mechanisms, covering ischemia-induced vascular changes, microcirculation disruption, blood flow determinants of recovery, and blood–brain barrier involvement [3], [14], [12], [13], [20].

• Therapeutic modulation of ischemia via physiologic/experimental interventions, focusing on reperfusion strategies, vasoactive approaches, and pharmacologic protection to limit irreversible damage [18], [5], [19], [15].

• Clinical prognosis and trajectories from transient ischemic attacks to survivor outcomes, highlighting prognostic variability, functional recovery, and population-level mortality trends [8], [10], [11].
