Outline of Annual Research Achievements

最終年度には、大阪大学神経科精神科、熊本大学精神科神経科などの多施設共同研究により、4大認知症、すなわち、アルツハイマー病(AD)、レビー小体型認知症(DLB)、血管性認知症(VaD)、ならびに前頭側頭葉変性症(FTLD)におけるアパシーの出現頻度、重症度、介護者の負担を認知症の重症度別に検討した。
対象はAD 1091名、VaD 249名、VaD 156名、FTLD 102名であった。認知症の重症度はClinical Dementia Rating (CDR)で、精神症状の評価尺度はNeuropsychiatric Inventory Distress Scale (NPI-D)を用いた。
ADとVaDでは、アパシーは認知症の進行に伴い重度化し、すべての重症度で最も頻度の高いBPSDであった。DLBでは、アパシーは認知症の進行に伴い重度化し、CDR 1, 2, 3で最も頻度の高いBPSDであった。CDR 0.5では幻視の頻度が最も高かった。FTLDでは、アパシーの重症度と認知症の重症度の関連は認められなかった。しかし、CDR 0.5, 2, 3では、最も頻度の高いBPSDであった。そして、これらの結果を英語論文(Kazui et al, PLOS one, 2016)に発表した。
初年度、昨年度は、4大認知症と健常高齢者の認知機能、アパシーを含む認知機能、神経画像のデータベースを構築し、多施設でデータ入力を開始し、最終年度の疾患別、重症度別のアパシーの出現傾向に関する研究につながった。また、データベースに蓄積した約1500例のMRIならびにSPECT画像は、現在分担研究者らにより解析中である。
本研究により、アパシーは、4大認知症すべておいて、ほとんどの重症度で最も頻度の高いBPSDであることが明らかになり、血管障害例の機能回復にも大きな影響を与えることが明らかになった。
