Outline of Final Research Achievements

Regarding REM sleep behavior disorder (RBD), which is considered to be a precursor state of α-synucleinopathy, we evaluated the progress process of RBD to α-synucleinopathy in the present study. In the follow-up period of the present study, the frequency of progression from RBD to α-synucleinopathy was lower than in the previous report. However, from the time of the RBD state, it was found that some abnormal findings existed in the higher brain function evaluation and the neurological symptom evaluation.

Academic Significance and Societal Importance of the Research Achievements

レム睡眠行動異常症(RBD)は神経変性疾患の一部において、その前駆状態と考えられており本研究領域で注目を集めている。このRBDからα-シヌクレイノパチーへの進展過程にアプローチし、その病態および神経基盤を明らかにすることは、神経変性疾患の早期発見・発症予測する客観的なearly markerの同定、新しい臨床診断方法や発症前の予防介入、治療評価への臨床応用につながるものと考えられ、その意義は大きい。
