What is the purpose of this trial?

This trial tests a new version of the Memory Support Intervention (MSI) to determine its effectiveness in improving sleep and memory in individuals with sleep disorders. It includes two groups: one receiving MSI combined with a treatment for sleep and circadian issues, and another receiving only the sleep treatment. The goal is to discover if these treatments can reduce sleep problems and improve daily function. Individuals aged 50 or older with mobility issues, low income, and sleep disturbances might be suitable candidates. As an unphased trial, this study offers a unique opportunity to contribute to research that could enhance sleep and memory support for many.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that treatments like the Transdiagnostic Intervention for Sleep and Circadian Dysfunction (TranS-C) are effective and generally safe. Studies have found that these treatments improve sleep and daily activities in people with various mental health conditions. Researchers are now testing the Memory Support Intervention (MSI) with TranS-C to see if it can enhance these benefits further.

Participants in similar studies have typically tolerated the treatments well, with no major side effects reported. This suggests that the treatments are safe for most people.

Consulting a healthcare provider before joining a trial is always important to ensure it is suitable. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about these interventions because they offer a comprehensive approach to treating sleep disorders by targeting both sleep patterns and memory support. Unlike standard treatments that often focus solely on regulating sleep cycles, the Transdiagnostic Intervention for Sleep and Circadian Dysfunction (TranS-C) addresses a broad range of sleep-related issues, which could lead to more effective results for diverse sleep problems. Additionally, when combined with the Memory Support Intervention (MSI), this approach could enhance cognitive functions affected by poor sleep, offering a dual benefit that current treatments don't typically provide. This combination could pave the way for more personalized and effective management of sleep disorders.

What evidence suggests that this trial's treatments could be effective for sleep disorders?

Research has shown that the Transdiagnostic Intervention for Sleep and Circadian Dysfunction (TranS-C), which participants in this trial may receive, effectively improves sleep and mental health. Studies have found that TranS-C addresses various sleep issues and benefits individuals with serious mental health conditions. Participants in these studies reported better sleep and overall mental well-being. The Memory Support Intervention (MSI), another treatment option in this trial, aims to enhance these benefits by helping patients remember and maximize their treatments. Although specific data on using TranS-C and MSI together is not yet available, each has shown promise individually. ^{1 3 6 7 8}

Published Research Related to This Trial

Older adults with mild cognitive impairment (MCI) show altered circadian rest/activity rhythms, including greater nighttime activity and reduced morning activity compared to cognitively normal individuals, based on a study of 179 participants.

Certain circadian rhythm metrics, including the novel fPC3 and standard measures like relative amplitude, are linked to better cognitive performance, particularly in episodic memory and executive function, suggesting that sleep patterns may influence cognitive health.

Associations of actigraphic sleep and circadian rest/activity rhythms with cognition in the early phase of Alzheimer's disease. Alfini, A., Albert, M., Faria, AV., et al.[2023]

Individuals with mild cognitive impairment (MCI) show significant disruptions in circadian rhythms, such as changes in rest-activity patterns and hormone levels, which are linked to cognitive deficits.

Restoring regular circadian rhythms may offer a promising intervention to prevent or slow the progression of neurodegenerative diseases and improve cognitive function in MCI patients, highlighting the need for further longitudinal studies.

Participants with serious mental illness who had multiple sleep and circadian problems experienced greater overall impairment and psychiatric symptoms, highlighting the importance of addressing these issues in treatment.

The Transdiagnostic Sleep and Circadian Intervention (TranS-C) combined with usual care led to significant improvements in sleep and psychosocial functioning for various specific sleep problems, demonstrating its effectiveness regardless of the number of sleep issues present.

The 'Sleep Well, Think Well' (SWTW) intervention significantly improved subjective sleep quality in older adults with mild cognitive impairment (MCI), with a large effect size (Cohen's d = 0.83) based on a study of 35 participants over eight weeks.

While the SWTW program showed promise in reducing daytime sleepiness (Cohen's d = 0.70), it did not significantly impact cognitive functioning, depressive symptoms, or objective sleep measures, indicating that while sleep quality improved, other cognitive outcomes may require different interventions.

In a study involving healthy older adults, consistent circadian activity rhythms were found to enhance associative memory performance, regardless of total sleep time or physical activity levels.

The research indicated that hippocampal activity during memory retrieval is positively linked to both memory accuracy and the consistency of circadian rhythms, suggesting that these rhythms could serve as a biomarker for cognitive function in aging.

A 24-week randomized controlled trial will test a personalized chronotherapy intervention, including bright light therapy and tailored physical activity, to improve sleep quality in 96 older adults with mild cognitive impairment (MCI).

Improving sleep quality through this intervention may help maintain cognitive health and reduce the risk of dementia in older adults, addressing a common issue among those with MCI.

In a study of 45 seniors, including 16 with mild cognitive impairment (MCI), it was found that those with amnestic MCI (aMCI) experienced less sleep disturbance compared to those with nonamnestic MCI (naMCI) and cognitively intact individuals, as measured by objective sleep metrics over a 6-month period.

The findings suggest that the type of MCI may influence sleep patterns, with naMCI showing more disturbed sleep than aMCI, indicating potential differences in the underlying pathology of these MCI subtypes.

A six-session cognitive behavioral therapy for insomnia (CBT-I) significantly improved sleep quality in older adults with mild cognitive impairment (MCI), as shown in a study with 28 participants.

The intervention also led to improvements in executive functioning, particularly in tasks related to inhibition, suggesting that better sleep may positively influence cognitive abilities in individuals with MCI.

In a study involving 33 participants (11 with mild cognitive impairment, 11 with mild Alzheimer's disease, and 11 healthy controls), those with mild cognitive impairment and Alzheimer's showed significantly reduced rapid eye movement sleep and cyclic alternating pattern parameters, indicating disrupted sleep architecture.

The findings suggest that decreased sleep instability in individuals with mild cognitive impairment and Alzheimer's disease may serve as a potential biomarker for neurodegeneration, highlighting the link between sleep quality and cognitive decline.
