Background

Research Context and Motivation

Ultra-Aged Society in 2025

2025년 초고령 사회 진입

65세이상의 노인 인구가 전체 인구의 20%이상을 차지

A Surge in Neurological Diseases Due to an Ultra-Aged Society

초고령화 사회로 인한 신경계 질환의 급증

뇌졸중, 뇌위축, 치매와 같은 뇌질환 환자의 기하급수적 증가

Scarcity of Neurological Specialists

신경계 전문 인력의 희소성

신경과·신경외과 전문의는 전체 의사의 5.7%에 불과

Complexity of Neuroimaging Interpretation

MRI, CT 영상 해석의 난해함

복잡한 영상 구조와 미세한 병변으로 판독 난이도가 매우 높음

The Urgency and Fatality of Neurological Diseases

신경계 질환의 긴급성과 직결되는 치명성

뇌졸중은 단일질환 사망률 2위

Regional Imbalance in the Distribution of General Hospitals

병원 접근성의 지역별 불균형

강원·제주지역은 3차 종합병원 진료가 매우 어려움
