  • World Hearing Day: Equal access to early interventions key to supporting children globally, says Brock prof

    MEDIA RELEASE— February 27, 2026 — R0024 

    This World Hearing Day, Hillary Ganek and her students are teaming up with the Cochlear Implant International Community of Advocacy (CIICA) to support families of children with hearing loss in developing countries.

    Organized by the World Health Organization, the global advocacy campaign is this year focused on the need to improve hearing care for all children, which is also a research priority for the Brock University Assistant Professor of Applied Linguistics. 

    Ganek’s project with CIICA, a European non-profit organization, involves families from low- and middle-income countries around the world whose children have benefitted from cochlear implants. These permanent electronic devices digitize sounds and transmit them to the cochlear nerve to help treat hearing loss. 

    By collecting and sharing stories from families who have accessed cochlear implants for their child along with the support services that enable the surgery and ensuing therapy, Ganek and CIICA hope to identify areas that require additional advocacy in different countries. 

    “In the past 30 years, there have been significant developments in the way that we treat hearing loss in high-income countries,” says Ganek, a speech-language pathologist and certified auditory-verbal therapist. “We are able to identify children with hearing loss at birth, which means we can capitalize on the fact that infants are learning to listen and talk from the very moment that they are born, and even before, as they’re listening in the womb.” 

    Because the brain has evolved to learn language from birth, early diagnosis of hearing loss is critical to language acquisition and improved outcomes for children, she says.  

    “If we diagnose a child with hearing loss, we can get them fitted with hearing technology, whether that’s a hearing aid, cochlear implant or another device, by the time they’re six months old,” says Ganek. “Then we get them into speech therapy or sign language class so that they are learning to communicate when their brain is meant to be learning to communicate.”

    Research shows the results of this early treatment are dramatic, with many children acquiring age-appropriate language skills by the time they start school. 

    However, Ganek says with 80 per cent of people with hearing losses living in low-resource settings, children can miss out on treatment during this critical developmental window.  

    “Children in different health-care systems may have hearing loss because they have less access to vaccination programs and medications that fight infectious diseases. They are also more likely to have been given ototoxic prescription drugs, which can damage hearing as a side effect,” she says. 

    When those risk factors are compounded by limited access to hearing screenings, technologies to treat hearing loss and professional speech-language pathologists to provide interventions, the inequity becomes even greater. 

    “This work with CIICA is to draw attention to the few families who have been able to get their children this technology and find support,” says Ganek. “We can then look at what we need to do in the hearing-loss community to ensure that the path to treatment and support is less difficult and available to more families.”

    With the support of a student team, Ganek will prepare the families’ stories to share on the CIICA website along with a map showing where the families live. The families’ journeys will be available online Tuesday, March 3, when World Hearing Day is observed.

    Once the awareness elements are in place, the team will then analyze the personal narratives to identify common themes and experiences, which can inform the development of a policy paper to help guide CIICA and other advocates.

  • Grad student uncovering hidden drivers of dementia risk with national award 

    MEDIA RELEASE— February 26, 2026 — R0023 

    While high blood pressure, diabetes and a sedentary lifestyle are linked to dementia, the exact molecular connection between these risk factors and the disease remain something of a mystery. 

    These factors can damage proteins in the body, which plays a role in brain decline, says Brock University PhD student Shakiru Alaka. However, it’s hard to measure the real-time changes inside the cells of a living patient as a result of that damage, particularly in the brain.

    Alaka is seeking to solve that puzzle after receiving one of 14 Heart & Stroke and Brain Canada 2025-26 Personnel Awards for Black Scholars.

    “This national recognition supports my research in dementia, Alzheimer’s disease and equitable health outcomes and represents an important milestone both personally and for the Brock community,” he says.  

    The grant will support his current research project, “Investigating Degenerative Protein Modifications as Molecular Mediators Linking Vascular Risk Factors to Alzheimer’s Disease and Dementia.”  

    Alaka is examining a wide range of data gathered under the Canadian Longitudinal Study on Aging, a national research initiative following more than 50,000 people ages 45 to 85 over a 20-year period.  

    The database includes extensive biological samples, molecular profiling data, physiological measurements like blood pressure, comprehensive cognitive assessments, and detailed demographic and lifestyle information, including smoking status and physical exercise levels. 

    Using artificial intelligence, Alaka aims to uncover patterns and hidden connections between lifestyle factors and degenerative protein damage, which can weaken cells, impair blood vessels and cause chronic inflammation. 

    Impaired blood vessels result in less oxygen and nutrients travelling to the brain, leading to memory loss, a higher chance of stroke and the onset of Alzheimer’s disease and dementia, he says. 

    He will compare the Canadian results to information gleaned from similar large-scale studies in the United States, the United Kingdom and Singapore to ensure the results are relevant across human populations.

    Alaka traces his interest in damaged proteins and brain functioning back to his master’s research, which focused on the mechanisms of strokes, saying that people who suffer strokes sometimes end up developing dementia.  

    “Unfortunately, there is no cure for dementia or Alzheimer’s disease at the moment,” he says. “If we can find specific biomarkers, we could develop tools to identify people at risk earlier, take preventive steps to slow down the disease and eventually develop better and more effective treatments.” 

    Alaka’s supervisor is Professor of Health Sciences Newman Sze, who is also the Canada Research Chair in Mechanisms of Health and Disease

    Last August, Sze led an international research team that found adding a resting heart rate measure to an American dementia risk prediction model can make the model’s results more accurate across most racial groups. Alaka was lead author in the subsequent journal article detailing the team’s findings. 

    “Shakiru’s curiosity and determination make him an outstanding young scientist,” Sze says. “This award recognizes both the strength of his research and the importance of supporting Black scholars in improving heart and brain health across diverse communities.”

    Alaka is the first Brock University recipient of the Personnel Awards for Black Scholars, which aim to boost heart and brain health science within Black communities by supporting Black post-graduate students’ research. The awards were launched in 2023 with funding support from Heart & Stroke, Brain Canada Foundation, Health Canada, the Government of Canada’s Canadian Institutes of Health Research (CIHR) and CIHR’s Institute of Circulatory and Respiratory Health. 

    Heart & Stroke is Canada’s leading health charity devoted to heart disease and stroke. Brain Canada brings together those who support and advance brain research.
