A study from the University of Michigan reveals a concerning trend: despite the known advantages of early detection and expanding treatment options for Alzheimer’s disease and related dementias, cognitive screening tools remain underused. Researchers at the U-M School of Public Health and Michigan Medicine analyzed responses from nearly 1,300 participants aged 65-80 in the National Poll on Healthy Aging. The findings indicate that only about one-fifth of older Americans have undergone cognitive screening within the past year. This statistic is particularly low among certain racial and ethnic minority groups. With over 6.5 million people in the U.S. affected by dementia, and this number expected to double by 2060, the implications are profound. Despite awareness of the benefits—such as earlier treatment and better financial planning—the underuse persists due to various barriers at patient, provider, and healthcare system levels.

The research underscores the importance of addressing cognitive health early. Early conversations can lead to more opportunities for prevention, symptom management, and effective treatment. According to Chelsea Cox, a doctoral student at U-M, early intervention allows individuals and their families to make informed decisions about medical, financial, and legal matters. Scott Roberts, a professor at U-M, emphasizes that treatments are now available to slow the progression of Alzheimer’s if started early, making discussions with doctors crucial for older adults.

One of the key challenges highlighted by the study is the disparity in screening rates among different demographic groups. Hispanic and Asian American populations, for instance, show lower rates of cognitive screening compared to other groups. This discrepancy points to systemic issues that need addressing to ensure equitable access to screening and treatment. The researchers also note that Medicare covers cognitive testing for beneficiaries, yet many cases still go undiagnosed and untreated. This situation underscores the need for improved communication between patients and healthcare providers, as well as enhanced support systems within the healthcare infrastructure.

Early detection of Alzheimer’s disease and related dementias can significantly impact not just individuals but entire families and social systems. By fostering greater awareness and reducing barriers to screening, healthcare providers can help millions of older Americans receive timely care and support. The study calls for a concerted effort to bridge the gap between awareness and action, ensuring that more people benefit from the available resources and advancements in dementia diagnosis and treatment.
