Outline of Research at the Start

慢性不眠症の治療抵抗要因の中で最も対応に困窮するのが睡眠状態誤認(Sleep state misperception; SSM)である。SSMは客観的睡眠が改善しているにも関わらず主観的な睡眠評価が低く留まる病態像である。睡眠薬の多剤併用・長期投与に陥る主な原因一つであり、その抑止の観点からもSSMのリスク要因分析、臨床診断および治療法の開発が求められている。本研究では、通常生活環境下において客観的睡眠状態を同一個人内で長期間にわたり測定することでSSMの実態把握とリスク要因分析を行い、その後にSSMフィードバック型認知行動療法プログラム(sCBT-I)と適用判定アルゴリズムの作成する。

Outline of Final Research Achievements

A risk factor analysis of sleep state misperception in chronic insomnia was conducted. Thirty-one patients with treatment-resistant chronic insomnia (mean age 63.2 years) and 42 healthy controls (59.6 years) were simultaneously recorded in a sleep diary and actigraph MTN and evaluated for daytime functional impairment. The insomnia group reported 62 minutes less subjective total sleep time, 39 minutes longer wake time after sleep onset, and 28 minutes longer sleep latency than the control group. The insomnia group had a significantly longer total bedtime (45 minutes). The insomnia group had significantly poorer daytime dysfunction. In the insomnia group, the longer the time-in-bed and the earlier the bedtime, the greater the sleep state misperception. These results indicate that the presence of sleep state misperception in the insomnia group is associated with bedtime behavior.

Academic Significance and Societal Importance of the Research Achievements

慢性不眠症の治療抵抗要因の中で最も対応に困窮するのが睡眠状態誤認(Sleep state misperception; SSM)である。SSMは客観的睡眠が改善しているにも関わらず主観的な睡眠評価が低く留まる病態像で、薬物療法が奏功せず難治性である。睡眠薬の多剤併用・長期投与に陥る主な原因一つであり、その抑止の観点からもSSMのリスク要因分析、臨床診断および治療法の開発が求められている。本研究の成果は不眠症に対する認知行動療法の主要コンポーネントである睡眠制限法の理論的根拠とも合致した所見であり、睡眠薬の適正使用の推進にも寄与する。
