Siemens Healthineers Collaborates with ADDF for Alzheimer’s Speech Biomarker Development

Collaboration for Detecting Alzheimer’s Disease

In a significant advancement for Alzheimer’s research, the Alzheimer’s Drug Discovery Foundation's (ADDF) Diagnostics Accelerator (DxA) has announced a new partnership with Siemens Healthineers. This collaboration aims to leverage the SpeechDx dataset—a comprehensive collection designed to discover speech-based biomarkers for early Alzheimer’s detection.

A New Frontier in Alzheimer's Detection

The SpeechDx dataset was initiated in 2023 and represents the largest longitudinal collection of speech and clinical data specifically integrated to facilitate Alzheimer’s research. Current understanding indicates that changes in speech patterns can serve as early indicators of cognitive decline, often appearing 20-30 years before clinical symptoms manifest. Such insights present a crucial opportunity for earlier intervention in Alzheimer’s disease progression.

Dr. Howard Fillit, ADDF Co-Founder and Chief Science Officer, emphasizes the importance of this collaboration, stating, "Our partnership with Siemens represents the first of many collaborations utilizing the SpeechDx dataset to pioneer a new class of tools and biomarkers against Alzheimer’s."

With this landmark partnership, Siemens Healthineers becomes the first entity to non-exclusively license the SpeechDx dataset, intending to develop innovative speech-based biomarkers that align with the broadened goals of early detection and monitoring of Alzheimer’s.

The Potential of Speech Data

The richness of the SpeechDx dataset stems from its rigorous data collection methodology. Researchers have gathered information from about 2,000 participants, representing diverse demographics and clinical backgrounds, continuously tracking potential cognitive declines over three years. This dataset encompasses varied speech samples collected in three languages: English, Spanish, and Catalan, further deepening its applicability across populations.

Notably, the SpeechDx project is positioned to tackle some of the prevailing challenges in Alzheimer’s diagnostics. Dr. Arejas J. Uzgiris, the neurology innovation lead at Siemens Healthineers, outlines that access to ethically sourced large patient cohorts has historically limited advancements. The combined efforts under this partnership look toward overcoming such barriers, enabling enhanced predictive capabilities regarding Alzheimer’s disease progression.

Transforming Alzheimer's Diagnostics

The implications of validating speech as a digital biomarker are profound. According to Dr. Rhoda Au from Boston University, the relatively low-cost access to microphones integrated into everyday devices like smartphones creates an unprecedented opportunity for widespread screening. By analyzing the interplay between cognitive assessments and speech data, a more comprehensive screening method can emerge, facilitating earlier diagnoses and ultimately improving patient outcomes.

Furthermore, the collaborative endeavor aims to achieve important milestones such as releasing dataset findings to partners starting in 2025 and completing data collection by 2028. Such timelines will allow for thorough analyses and progressive development of biomarkers that could revolutionize how Alzheimer's disease is diagnosed and monitored.

The Role of ADDF

As the only public charity dedicated solely to Alzheimer’s drug development, the ADDF aims to fund research acceleration and foster collaborations that can lead to breakthroughs. With a robust track record of funding multiple research programs and clinical trials globally, the foundation remains at the forefront of fighting Alzheimer’s.

The DxA initiative, established in 2018, exemplifies a commitment to pioneering accessible diagnostics while supporting the rapid exploration of biomarkers. With contributions from several philanthropic partners, including Bill Gates and Jeff Bezos, this partnership underscores a united front in addressing one of the most pressing healthcare challenges of our time.

In summary, the collaboration between ADDF's DxA and Siemens Healthineers marks an exciting and critical development in the quest to improve Alzheimer’s disease diagnostics, offering the promise of harnessing speech data for better early detection and intervention strategies.
