Effects of cognitive-behavioral therapy for insomnia during sedative-hypnotics withdrawal on sleep and cognition in older adults

Author(s): Barbaux L; Cross NE; Perrault AA; Es-Sounni M; Desrosiers C; Clerc D; Andriamampionona F; Lussier D; Tannenbaum C; Guimond A; Grenier S; Gouin JP; Dang-Vu TT;

Objectives: Our objective was to assess the effect of cognitive-behavioral therapy for insomnia (CBTi) on subjective and objective sleep quality (including sleep spindles) and cognition during a sedative-hypnotics withdrawal program in older adults with insomnia disorder.

Identification of five sleep-biopsychosocial profiles with specific neural signatures linking sleep variability with health, cognition, and lifestyle factors

Author(s): Perrault AA; Kebets V; Kuek NMY; Cross NE; Tesfaye R; Pomares FB; Li J; Chee MWL; Dang-Vu TT; Yeo BTT;

Sleep is essential for optimal functioning and health. Interconnected to multiple biological, psychological, and socio-environmental factors (i.e., biopsychosocial factors), the multidimensional nature of sleep is rarely capitalized on in research. Here, we deployed a data-driven approach to iden ...

Effect of chronic benzodiazepine and benzodiazepine receptor agonist use on sleep architecture and brain oscillations in older adults with chronic insomnia

Author(s): Barbaux L; Perrault AA; Cross NE; Weiner OM; Es-Sounni M; Pomares FB; Tarelli L; McCarthy M; Maltezos A; Smith D; Gong K; O' Byrne J; Yue V; Desrosiers C; Clerc D; Andriamampionona F; Lussier D; Gilbert S; Tannenbaum C; Gouin JP; Da ...

Study objectives: Insomnia in older adults is associated with widespread benzodiazepine (BZD) and benzodiazepine receptor agonist (BZRA) use, despite evidence that chronic use disrupts sleep regulation and cognition. Little is known about BZD/BZRA effects on NREM slow oscillations (SO), spindles ...

Phase-Amplitude Coupling of NREM Sleep Oscillations Shows Between-Night Stability and is Related to Overnight Memory Gains

Author(s): Cross N; O' Byrne J; Weiner OM; Giraud J; Perrault AA; Dang-Vu TT;

There is growing evidence in humans linking the temporal coupling between spindles and slow oscillations during NREM sleep with the overnight stabilization of memories encoded from daytime experiences in humans. However, whether the type and strength of learning influence that relationship is still unknown. Here we tested whether the amount or type of ver ...

Cognitive-behavioural therapy for insomnia mechanism of action: Exploring the homeostatic K-complex involvement

Author(s): Sforza M; Morin CM; Dang-Vu TT; Pomares FB; Perrault AA; Gouin JP; Bušková J; Janku K; Vgontzas A; Fernandez-Mendoza J; Bastien CH; Riemann D; Baglioni C; Carollo G; Casoni F; Zucconi M; Castronovo V; Galbiati A; Ferini-Strambi L;

Investigating the mechanisms of action of cognitive-behavioural therapy for insomnia (CBT-I), the first-line treatment for chronic insomnia disorder (ID), can contribute to the overall understanding of insomnia and its treatment. To date, no study has examined the relationship between K-complexes ...

NREM sleep brain networks modulate cognitive recovery from sleep deprivation

Author(s): Lee K; Wang Y; Cross NE; Jegou A; Razavipour F; Pomares FB; Perrault AA; Nguyen A; Aydin Ü; Uji M; Abdallah C; Anticevic A; Frauscher B; Benali H; Dang-Vu TT; Grova C;

Decrease in cognitive performance after sleep deprivation followed by recovery after sleep suggests its key role, and especially non-rapid eye movement (NREM) sleep, in the maintenance of cognition. It remains unknown whether brain network reorganization in NREM sleep stages N2 and N3 can uniquel ...

A multidimensional investigation of sleep and biopsychosocial profiles with associated neural signatures

Author(s): Perrault AA; Kebets V; Kuek NMY; Cross NE; Tesfaye R; Pomares FB; Li J; Chee MWL; Dang-Vu TT; Yeo BTT;

Sleep is essential for optimal functioning and health. Interconnected to multiple biological, psychological and socio-environmental factors (i.e., biopsychosocial factors), the multidimensional nature of sleep is rarely capitalized on in research. Here, we deployed a data-driven approach to ident ...

A Pilot Randomized Trial of Combined Cognitive-Behavioral Therapy and Exercise Training Versus Exercise Training Alone for the Management of Chronic Insomnia in Obstructive Sleep Apnea

Author(s): Cammalleri A; Perrault AA; Hillcoat A; Carrese-Chacra E; Tarelli L; Patel R; Baltzan M; Chouchou F; Dang-Vu TT; Gouin JP; Pepin V;

Insomnia treatment among individuals with comorbid insomnia and obstructive sleep apnea is suboptimal. In a pilot randomized controlled trial, 19 individuals with comorbid insomnia and obstructive sleep apnea were allocated to one of two arms: EX + EX, consisting of two 8-week phases of exercise ...

Author(s): Perrault AA; Kebets V; Kuek NMY; Cross NE; Tesfaye R; Pomares FB; Li J; Chee MWL; Dang-Vu TT; Thomas Yeo BT;

Sleep is essential for optimal functioning and health. Interconnected to multiple biological, psychological and socio-environmental factors (i.e., biopsychosocial factors), the multidimensional nature of sleep is rarely capitalized on in research. Here, we deployed a data-driven approach to ident ...

Methodological approach to sleep state misperception in insomnia disorder: Comparison between multiple nights of actigraphy recordings and a single night of polysomnography recording

Author(s): Maltezos A; Perrault AA; Walsh NA; Phillips EM; Gong K; Tarelli L; Smith D; Cross NE; Pomares FB; Gouin JP; Dang-Vu TT;

Study objective: To provide a comprehensive assessment of sleep state misperception in insomnia disorder (INS) and good sleepers (GS) by comparing recordings performed for one night in-lab (PSG and night review) and during several nights at-home (actigraphy and sleep diaries). Methods: Fifty-sev ...

Effects of cognitive behavioral therapy for insomnia on subjective and objective measures of sleep and cognition

Author(s): Perrault AA; Pomares FB; Smith D; Cross NE; Gong K; Maltezos A; McCarthy M; Madigan E; Tarelli L; McGrath JJ; Savard J; Schwartz S; Gouin JP; Dang-Vu TT;

Study objectives: To assess the effects of Cognitive Behavioral Therapy for insomnia (CBTi) on subjective and objective measures of sleep, sleep-state misperception and cognitive performance. Methods: We performed a randomized-controlled trial with a treatment group and a wait-list control group ...
