Sleep clinical trials at UCSF
4 in progress, 3 open to eligible people

  • Autonomic Mechanisms of Sleep-dependent Memory Consolidation

    open to eligible people ages 18-64

    The goal of the proposed project is to identify the impact vagal activity during sleep for memory formation. Nearly 100 years of research contends that sleep plays a critical role in memory consolidation (i.e. the transformation of recent experiences into stable, long-term memories), yet much of this literature has focused on the central nervous system and technologies like electroencephalography (EEG) to unpack neural correlates involved in memory processing. Sleep is also a unique period of autonomic variation and an expansive literature has indicated the critical importance of the autonomic nervous system for memory formation. This project would be amongst the first to examine the autonomic nervous system during sleep as a critical, causal pathway linking sleep to memory processing. The investigators will assess the impact of non-invasive, transcutaneous vagal nerve stimulation on sleep and post-sleep memory performance. Autonomic physiology, including electrocardiography and impedance cardiography, will be gathered at baseline, before the memory task and continuously during sleep to examine vagal tone (i.e. heart rate variability) and sympathetic activation (i.e. pre-ejection period) in response to both active and sham stimulation conditions. Polysomnography will also be gathered during the nap to examine sleep architecture. The proposed research will address a critical gap in the literature by: 1) examining the causal role of the ANS for memory functioning in humans, 2) extending the current understanding of sleep's impact on memory processing, and 3) set the groundwork for novel, sleep-based interventions with the goal of improving cognitive health.

  • Summertime: Kids in Motion

    open to eligible people ages 8-10

    This is a 3-week randomized crossover study to determine the effect of the prior night's sleep duration on energy-balance related behaviors of diet and physical activity the following day. In Week 1, child participants will sleep their usual amount. In week 2, participants will be randomized to either a sleep restricted or a healthy sleep condition for 4 nights. In week 3, participants will cross over to the opposite sleep condition for 4 nights.

  • The Impact of 8 Weeks of Digital Meditation Application and Healthy Eating Program on Work Stress and Health Outcomes

    open to eligible people ages 18 years and up

    The aim of the present study is to test the effects of a digital meditation intervention and/or a healthy eating intervention in a sample of UCSF employees with overweight and obesity (BMI>=25kg/m2) who report mild to moderate stress. We will randomize UCSF employees to 8-weeks of a digital meditation intervention (using the commercially available application, Headspace), a healthy eating intervention, a digital meditation+healthy eating intervention, or a waitlist control condition.

  • Napping, Sleep, Cognitive Decline and Risk of Alzheimer's Disease

    Sorry, not yet accepting patients

    This study aimed to pilot test a non-pharmacological (behavioral) treatment program targeting improved cognition through improving 24-h sleep-wake cycle in people with mild cognitive impairment (MCI) or mild Alzheimer's disease. A treatment program incorporating bright light therapy and a modified cognitive behavioral therapy for insomnia will be developed to address 24-hour patterns of sleep. We will then pilot test its feasibility and explore its preliminary effects on improving sleep/napping and cognition in patients with MCI or mild Alzheimer's disease.
