[History of Japanese Brain Dock]

Brain dock was introduced in Japan in 1988. Initially, DSA was used to detect unruptured cerebral aneurysms, and in the same year, brain dock using MRI to detect asymptomatic cerebrovascular lesions was initiated. Subsequently, the performance of the MRA improved, and all brain docks were made by MRI. A brain aneurysm was discovered in the brain dock and preventive surgery was performed. MRI-detected asymptomatic cerebral infarctions and microbleeds raise stroke risk, while preventive care improves with better risk factor management. In recent years, the role of brain dock technology has expanded beyond stroke prevention, as it is increasingly recognized for its potential in the early prevention of cognitive impairment.
