Sleep Disturbance and Emotion Regulation Brain Dysfunction as Mechanisms of Neuropsychiatric Symptoms...

Alzheimer DiseaseMild Cognitive Impairment2 more

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.

GamePlan4Care: Online Support for Family Caregivers

Dementia

As the population of older adults grows, almost doubling in size from 2012 to 2040, so too will the need for family caregiving. Caregiving can lead to negative psychosocial outcomes such as depression, anxiety, and burden; social isolation and family conflict: financial strain due to costs of care; and some caregivers also experience negative health consequences. This project will test the value of GamePlan4Care (GP4C) an evidence-based, internet-enabled system capable of providing immediate, tailored education and skills training to caregivers who can access live support from a DCS via phone or web-based video.

Self-Care for Dementia Caregivers

AgingMental Disorder8 more

The Self-Care for Dementia Caregivers research study is a pilot randomized control trial (RCT) to develop and evaluate the feasibility of a behavioral intervention that uses technology and motivational health coaching to optimize caregivers' sleep, exercise, and social activities. Caregivers of family members with Alzheimer's Disease (AD) and AD-related dementias often experience disruptions of their biological or behavioral time cues, placing them at higher risk for adverse health outcomes. The investigators hypothesize that targeting the stability of sleep, exercise, and social activities will improve stability of the biological clock, improve caregiver health and wellbeing, and improve their ability to provide care.

Cognitive Effects of Roflumilast in (a)MCI and Mild Dementia Patients

Mild Cognitive ImpairmentMild Dementia1 more

The aim of the current project is to validate whether chronic intake (24 weeks) roflumilast (PDE4 inhibitor) can improve cognition in patients with (amnestic) mild cognitive impairment (MCI) and in patients with mild dementia. The project will demonstrate whether episodic memory, but also attention, information processing or executive function improves with chronic administration of roflumilast in (a)MCI and mild dementia patients.

Stimulation of Cingulo-opercular Alertness Network

Lewy Body DiseaseLewy Body Variant of Alzheimer Disease1 more

Fluctuations in alertness are very common in persons with Lewy body dementias and are a major source of disability. Changes in a chemical messenger molecule called acetylcholine within certain brain regions may play a role in these fluctuations. We propose to test this hypothesis and also determine whether a non-invasive way of stimulating affected brain regions may be of relevance for future management of these fluctuations.

Clinical Study of Neflamapimod in Patients With Dementia With Lewy Bodies

Dementia With Lewy Bodies

The purpose of this study is to determine whether neflamapimod can improve learning skills, problem solving skills, and memory loss in people diagnosed with DLB. More specifically, improvement in verbal learning, memory, and attention, as well as cognitive and functional performance will be measured.
