Cumulus Neuroscience Showcases Breakthrough Findings on Alzheimer's at AAIC 2025 Annual Meeting

Cumulus Neuroscience, a prominent digital health organization dedicated to enhancing clinical trials and patient care in the realm of neuroscience, presented significant findings from their observational study, CNS-101, during the Alzheimer's Association International Conference (AAIC) 2025 in Toronto, Canada. This research has pivotal implications for how Alzheimer’s disease progression is monitored, marking a potential shift in clinical evaluation methods.

The core of the findings reveals that metrics generated from at-home testing via the NeuLogiq® platform demonstrated higher sensitivity to Alzheimer's pathology than traditional clinical methods. Traditional assessments, such as the Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog 13), have long been the benchmark for evaluating cognitive decline, but Cumulus' data suggests that these measures may not capture the full extent of disease progression.

The study focused on a group of 59 patients diagnosed with dementia, alongside a matched cohort of 60 healthy controls. Conducted across seven UK sites, including reputable institutions such as the University of Cambridge, this year-long, repeated sampling study involved the collection of plasma samples to ascertain disease pathology. Furthermore, participants were required to engage in a series of behavioral assessments and utilize a sleep EEG device for comprehensive data collection.

Dr. Brian Murphy, the Founder and Chief Scientific Officer of Cumulus Neuroscience, stated that clinic-based endpoints often provide only a snapshot of a patient’s condition, which impedes the ability to track the progression of Alzheimer’s accurately. The CNS-101 study underlines how patients' willingness to engage in these at-home assessments could revolutionize the way data is gathered in clinical trials, providing a scalable and objective alternative to conventional methods.

The study's design capitalized on behavioral assessments conducted on mobile devices and EEG readings, both executed within the comfort of patients' homes. This method not only improved participation compliance but also increased the frequency and variety of data points collected, yielding more robust and sensitive insights into patient cognitive health.

Dr. Emer MacSweeney, CEO of ReCognition Health, which acted as a key clinical site for the study, echoed these sentiments by emphasizing the importance of minimizing participant burden in clinical trials, particularly in Alzheimer's research. The CNS-101 study sets a precedent for the use of digital biomarkers in reducing the strains on both patients and healthcare providers.

Overall, findings from this research could streamline future clinical trials, decrease overall costs, and enable quicker go/no go decisions for pharmaceutical development. The results from the observational study may also propel further validation efforts to establish digital composite measures that could enhance the statistical power available in clinical research.

As Alzheimer's remains the most prevalent cause of dementia, affecting millions globally, the urgency to develop innovative assessment methods becomes increasingly critical. While a cure remains elusive, Cumulus Neuroscience and its mission to refine CNS clinical trials are positioned to make a lasting impact on the management and understanding of Alzheimer’s disease.
