What You Need to Know Before You Apply

What is the purpose of this trial?

This trial investigates how Rhythmic Auditory Stimulation (RAS) can enhance walking and cognitive skills in individuals with Alzheimer's disease (AD). People with AD often struggle with walking and thinking, increasing the risk of falls. The trial aims to determine if RAS can mitigate these risks by examining brain activity and walking patterns. Participants will undergo walking tests with music, and researchers will measure improvements in brain function and walking. Suitable candidates for this trial include those living independently, able to walk short distances unaided, and capable of communicating with researchers. Individuals with significant hearing issues or medical conditions affecting walking are not eligible. As an unphased trial, this study provides a unique opportunity to explore innovative methods for improving the quality of life for those with Alzheimer's.

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 study team or your doctor.

What prior data suggests that Rhythmic Auditory Stimulation is safe for individuals with Alzheimer's Disease?

A previous study found that 40 Hz sensory stimulation, similar to Rhythmic Auditory Stimulation (RAS), was safe and well tolerated in individuals with mild cognitive impairment and early-stage Alzheimer's disease. Another study demonstrated that RAS can improve walking and brain function, potentially reducing the risk of falls in people with Alzheimer's.

Research has also shown that movement training with musical rhythm, like RAS, activates the front part of the brain and enhances overall thinking skills. Overall, these studies suggest that RAS is generally safe and may benefit people with Alzheimer's by improving brain and movement functions.12345

Why are researchers excited about this trial?

Rhythmic Auditory Stimulation (RAS) for Alzheimer's disease stands out because it offers a non-pharmacological approach to potentially improving quality of life. Unlike standard treatments like cholinesterase inhibitors and memantine, which focus on slowing cognitive decline, RAS targets motor functions and brain activity through rhythmic auditory cues. This method could enhance gait quality and stimulate cortical activity, offering a novel way to address symptoms not typically targeted by current medications. Researchers are excited about the possibility of RAS providing a complementary strategy that could improve mobility and brain function in individuals with Alzheimer's disease.

What evidence suggests that Rhythmic Auditory Stimulation is effective for Alzheimer's Disease?

Research has shown that Rhythmic Auditory Stimulation (RAS) can aid individuals with Alzheimer's Disease (AD) by enhancing brain function. One study found that moving to music can improve thinking skills by activating the brain's prefrontal cortex, crucial for planning and decision-making. Another study discovered that RAS might help older adults with dementia improve their walking style. Although some results have varied, evidence suggests that RAS could boost mental abilities, particularly in those with mild to moderate AD symptoms. This trial will examine the effects of RAS on gait quality and brain activity in individuals with and without AD. Overall, these findings suggest that RAS might be a promising method to enhance both movement and mental function in people with AD.23456

Are You a Good Fit for This Trial?

This trial is for people diagnosed with Alzheimer's disease or mild cognitive impairment who have problems with walking and thinking. Participants should be older adults able to walk, and not have other major health issues that would prevent safe participation.

Inclusion Criteria

What Are the Treatments Tested in This Trial?

Interventions

  • Rhythmic Auditory Stimulation (RAS)

Trial Overview

The study tests whether using rhythmic sounds from a metronome (Rhythmic Auditory Stimulation) can help improve walking ability and brain function in people with Alzheimer's or mild cognitive impairment. Brain activity will also be measured during the intervention.
