The Effect of Bright Light Therapy on Migraine With Sleep Disturbance

Migraine is a common disabling disorder and its substantial burden is associated with considerable negative impact on quality of life. Several pharmacological treatments are available for migraine prophylaxis but insufficient efficacy and significant side effects preclude them being widely using in migraine treatment. Recently, growing evidences have suggested that migraines are closely associated with sleep and circadian rhythms. Sleep disturbance is well-known as one of the triggers for migraine episode, and too much sleep (i.e., sleeping more on weekend) can also trigger migraine attacks. In addition, shift-work or jet lag have been reported to be triggers in some migraines; regular and good sleep would benefit migraine. Intriguing, hypothalamus is thought to be migraine generator and sleep and circadian activity rhythm also under controlled by hypothalamus. The evidence suggests an influence of both sleep and the circadian system with migraine. In the past, clinical evidence has shown that light therapy can stabilize the sleep architecture and further improve insomnia related to circadian rhythm disorders. However, the beneficial effect of light therapy on migraine with sleep disturbance has not yet been determined. This randomized, double-blinded, placebo-controlled study aim to: Explore the clinical efficacy of bright light therapy for migraine prevention; Explore the underlying molecular and biochemical mechanisms of light therapy on migraine prevention.

The Effect of a Combined Nature-based and Virtual Mindfulness Intervention on Perceived Stress in Healthcare Workers

Rationale: Healthcare workers that care for patients with COVID-19 are at increased risk for stress-related symptoms. When these symptoms are chronic, they can result in burnout and other mental health conditions that can exacerbate the current national health crisis. Social distancing can limit the accessibility of mental health services. Feasible and effective interventions are needed to reduce stress-related symptoms and promote resilience in this population, while adhering to federal and local guidelines to mitigate the transmission of SARS-CoV-2. Objectives: To investigate the feasibility and efficacy of a combined nature-based and virtual mindfulness intervention on stress-related symptoms and psychological resilience in healthcare workers that care for patients with COVID-19. Both components are reported to reduce levels of perceived stress and increase psychological resilience; however, the potential additive effect of their combined delivery is unknown. Methods: Ninety healthcare workers will be randomized into one of three groups: Nature+Mindfulness (n=30), Nature only (n=30), and Control (n=30). All participants will undergo assessments at baseline (week 0), post nature intervention (~week 1), and post mindfulness intervention (~week 3). The two intervention groups will have one final assessment at 2-month follow-up (~week 11). Perceived stress is the primary endpoint and will be assessed with the Perceived Stress Scale. Secondary endpoints include sleep quality, burnout, posttraumatic stress, anxiety, depression, mindfulness, self-efficacy, and psycho-social-spiritual healing. Anticipated Results: We anticipate that participants in the Nature+Mindfulness group will have greater reductions in stress-related symptoms and greater increases in psychological resilience compared with the Nature only and Control groups.

Sleep Disturbance and Emotion Regulation Brain Dysfunction as Mechanisms of Neuropsychiatric Symptoms in Alzheimer's Dementia

Recent findings suggest that sleep disruption may contribute to the generation and maintenance of neuropsychiatric symptoms including anxiety, depression, agitation, irritation, and apathy while treating sleep disruption reduces these symptoms. Impairments in the neural systems that support emotion regulation may represent one causal mechanism mediating the relationship between sleep and emotional distress. However, this model has not yet been formally tested within a sample of individuals with or at risk for developing Alzheimer's Disease (AD) This proposal aims to test a mechanistic model in which sleep disturbance contributes to neuropsychiatric symptoms through impairments in fronto-limbic emotion regulation function in a sample of individuals at risk for developing, or at an early stage of AD. This study seeks to delineate the causal association between sleep disruption, fronto-limbic emotion regulation brain function, and neuropsychiatric symptoms. These aims will be achieved through a mechanistic, randomized 2-arm controlled trial design. 150 adults experiencing sleep disturbances and who also have cognitive impairment with the presence of at least mild neuropsychiatric symptoms will be randomized to receive either a sleep manipulation (Cognitive Behavioral Therapy for Insomnia CBT-I; n=75) or an active control (n=75). CBT-I improves sleep patterns through a combination of sleep restriction, stimulus control, mindfulness training, cognitive therapy targeting dysfunctional beliefs about sleep, and sleep hygiene education. Neuropsychiatric symptoms, fronto-limbic functioning, and sleep disruption will be assessed at baseline and at the end of the sleep manipulation through functional Magnetic Resonance Imaging (fMRI), clinical interviews, PSG recordings, and self-report questionnaires. Neuropsychiatric symptoms (anxiety and depression) and sleep disturbance (actigraphy, Insomnia Severity Index, and sleep diaries) will be assayed at baseline and each week throughout the sleep manipulation to assess week-to-week changes following an increasing number of CBT-I sessions. Wristwatch actigraphy will be acquired from baseline to the end of the sleep manipulation at week 11. Neuropsychiatric symptoms and sleep will be assessed again at six months post-manipulation.
