5 major Alzheimer’s discoveries scientists made in 2024
As 2024 comes to a close, experts in the field of Alzheimer’s disease are reflecting on the hopeful advances that have been made in diagnosis, treatment, and risk management. With an estimated 6.9 million Americans aged 65 and older currently living with Alzheimer’s, the road to a cure may seem long and uncertain. However, there have been significant discoveries throughout the year that offer promise for the future.
One of the most notable advances in 2024 was the approval of a new Alzheimer’s drug called Kisunla (donanemab) by the U.S. Food and Drug Administration (FDA) in July. This marks the third new approval for a dementia drug since 2021. Kisunla, developed by Eli Lilly, is a once-monthly injection designed to slow the progression of the disease by targeting amyloid plaques in the brain, which are known to impair memory and cognitive function in Alzheimer’s patients.
In addition to new treatments, research this year has also shown that blood tests could improve the speed and accuracy of Alzheimer’s diagnosis. Studies have demonstrated that blood tests can achieve a higher level of accuracy in identifying the disease, which could help patients gain faster access to clinical trials and treatments. This advancement brings us closer to utilizing blood tests for Alzheimer’s diagnosis in physicians’ offices.
Furthermore, a 2024 Alzheimer’s Association survey revealed that individuals newly diagnosed with Alzheimer’s and their caregivers are in need of more support in navigating the healthcare system. The majority of dementia caregivers expressed a desire for additional support systems, while also noting that coordination of care can be stressful. To address this need, the Centers for Medicare & Medicaid Services launched a pilot program called the GUIDE model, which aims to provide supportive services to people living with dementia and their caregivers.
Research in 2024 has also shown a link between air pollution, particularly from wildfire smoke, and an increased risk of dementia. A 10-year study presented at the Alzheimer’s Association International Conference found that wildfire smoke can be particularly hazardous for brain health, with air pollution from wildfires containing higher concentrations of toxic chemicals that can impact brain health.
Finally, a study published in June 2024 revealed physical changes in the brain that occur due to Alzheimer’s disease. These changes were found to precede the typical symptoms of memory loss and cognitive decline, offering new insights into the biological processes underlying the disease.
Overall, the progress made in 2024 offers hope for the millions of individuals living with Alzheimer’s and their caregivers. With continued research and support, there is optimism for a future where effective treatments and interventions can improve the lives of those affected by this devastating disease.
