Brain Dock is a comprehensive battery of medical tests that can detect occult pathologies such as unruptured aneurysms, tumors and asymptomatic brain infarctions. Its primary aim is to prevent stroke. We investigated Brain Dock findings of 50 Lion Corporation employees at Juntendo Tokyo Koto Geriatric Medical Center between January 2015 and December 2017. We compared the risk factors of hypertension, diabetes, hyperlipidemia, atrial fibrillation, chronic kidney disease and obesity between employees with and without abnormal MRI and MRA findings. We found that 18 (36.0%) of the employees had asymptomatic cerebral infarctions. The incidence of asymptomatic cerebral infarction increases with advancing age, and hypertension, whether treated or not, was a significant risk factor. These results were similar to those of previous reports. However, the fact that over 50% of assessed employees had some abnormal findings is notable. We recommend that all employees aged more than 50 years old should undergo cerebral assessments. In addition, more lectures and information about occupational health are needed in the workplace to educate employers and employees about cerebrovascular disease prevention, and how to prevent severe cerebral infarction.
