History of Stroke Discovery: From Ancient Observations to Modern Neuroimaging

Stroke understanding evolved over millennia:

1. Ancient era – Hippocratic texts describe sudden paralysis (“apoplexy”).
2. Renaissance – Vesalius’s anatomical illustrations advanced brain vascular knowledge.
3. 19th century – Bouillaud links stroke to cerebral hemorrhage; Virchow connects it to atherosclerosis and coins “thrombosis.”
4. Early 20th century – TIAs recognized as warning signs; cerebral artery occlusions documented.
5. Imaging revolution – CT (1970s) and MRI (1980s) enabled rapid, precise diagnosis of hemorrhage vs. ischemia.
6. Late 20th century – Mechanisms of ischemic stroke elucidated (platelet aggregation, coagulation cascade).
7. Ongoing research – Prevention, acute reperfusion, rehabilitation, and pathophysiology.

Each advance improved recognition, treatment, and outcomes for this leading cause of disability and death.
