Value Proposition: Novel method that measures levels of Alzheimer’s disease-related biomarkers to improve patient care and satisfaction for cochlear implant outcomes.
Technology Description
Researchers at Washington University in St. Louis have developed a method for collecting and analyzing perilymph fluid during cochlear implantation. Despite the success of using Cochlear implants (CIs), speech outcomes with CIs remain variable and unpredictable. This variability complicates the management of patient expectations, early identification of cases needing additional aural rehabilitation, and determination of optimal device function for each individual recipient. Currently, clinicians lack the ability to accurately predict a patient’s performance with the device, limiting their ability to provide personalized counseling and guidance.
This method addresses a critical commercial problem by providing a minimally invasive technique for collecting and analyzing perilymph fluid during cochlear implantation. By measuring levels of Alzheimer’s disease-related biomarkers such as amyloid-β and tau proteins using highly sensitive technologies like the Single Molecule Array (SiMoA), this innovation enables clinicians to predict individual CI performance better and to more deeply explore the connection between cognitive decline and inner ear health. This approach enhances understanding of hearing loss and its potential association with neurocognitive decline. Ultimately, it offers a novel approach to improving patient care and satisfaction by leveraging molecular diagnostics in cochlear implantation outcomes.
