PROBLEM TO BE SOLVED: To provide an onset risk forecasting system for cerebrovascular disease, capable of forecasting risk of disease, especially cerebrovascular disease, because there have been methods for obtaining forecasting of risk of disease onset, but in practice, continuous acquisition of biological information is required but it is difficult, and accuracy of onset risk change forecasting based on only acquired biological information is not improved.SOLUTION: A small pulse wave information acquisition element is attached to a subject, for continuously acquiring a pulse wave, and based on the pieces of pulse wave information which are continuously acquired, onset degree of cerebrovascular disease is forecasted, based on variation of the pulse wave waveform and blood pressure.SELECTED DRAWING: Figure 1【課題】疾病発症の危険度の予測を生体情報より得ようとする試みは従来からあったが、実用的には常時連続した生体情報取得が求められるが困難であり、また取得した生体情報のみに基づいた発症危険度変化予測の精度は上がらない。疾病、特に脳血管疾患発症の危険度を予測することのできる発症危険度予測システムを提供する。【解決手段】小型の脈波情報取得素子を被測定者に装着し常時連続取得し、この常時連続取得した脈波情報に基づいて血圧、脈波波形の変動から脳血管疾患の発症危険度を予測する。【選択図】図１
