Located in Nirasaki City, Yamanashi Prefecture, Akiyama Neurosurgery is a specialized clinic focusing on neurosurgery. The clinic emphasizes early detection and prevention of stroke and dementia, and has been offering "Stroke Diagnosis and Dementia Prevention Screening" since April 2008. This screening modifies traditional community health checkups with a strong focus on prevention as well as early disease detection, deeply rooted in the local community. The target age range is 40 to 74 years old, with patients receiving questionnaire forms and interviews. The clinic has also introduced VSRAD, an MRI-based early diagnosis support system for Alzheimer's-type dementia, capable of detecting brain changes that begin several years before dementia onset. Additionally, the clinic prescribes new migraine prevention drugs using CGRP receptor antagonists, expanding treatment options for patients who did not achieve sufficient results with conventional therapies. Parking is available for convenient car access. The clinic is closed on Thursdays, Sundays, national holidays, during the year-end and New Year period, and during the Obon season.
