Revolutionizing Alzheimer’s Diagnosis: A New Era of Hope and Innovation
The past two years have marked a turning point in the fight against Alzheimer’s disease, with groundbreaking advancements in diagnostics and treatment offering new hope for millions. For the first time, we have tools to target the underlying pathology of the disease, slowing cognitive and functional decline. At the heart of this progress are amyloid-targeting therapies, now FDA-approved for early symptomatic Alzheimer’s.But the key to unlocking their full potential lies in one critical factor: timely and accurate diagnosis.
The Urgency of Early Diagnosis
Table of Contents
Recent studies emphasize that the earlier treatment is initiated,the more patients can potentially benefit. This underscores the importance of diagnosing Alzheimer’s when symptoms first emerge. However, achieving this has been fraught with challenges. Conventional diagnostic methods, such as amyloid PET scans and cerebrospinal fluid (CSF) testing, are often inaccessible, invasive, and time-consuming.
A notable barrier is the shortage of neurologists, with 55% of primary care physicians reporting not enough neurologists in their communities. Compounding this issue, patients frequently confuse signs of cognitive impairment with signs of normal aging, delaying their request for evaluation.Alarmingly, nearly 98% of primary care physicians do not assess patients for cognitive impairment unless asked by a patient or loved one.
Innovation in Diagnostic Measures
Enter blood-based biomarker tests, a game-changing innovation in Alzheimer’s diagnostics. These tests identify or rule out circulating biomarkers in patients’ blood that correlate with pathologic proteins in the brain, such as amyloid and tau. Amyloid forms abnormal clumps known as amyloid plaques, which accumulate between neurons, while tau builds up twisted fibers called tau tangles inside neurons.For eligible patients, these tests can be paired with cognitive assessments and clinical findings to deliver an accurate and timelier diagnosis. High-quality blood biomarker tests are now more widely available through major reference laboratories, offering a less invasive and more accessible choice to traditional methods.
Expanding Access to Advanced Diagnostics
Efforts are also underway to improve access to established diagnostic tools.In 2023,the Centers for Medicare and Medicaid Services (CMS) removed coverage with evidence growth (CED) for beta-amyloid PET imaging,expanding its availability. This move is a significant step toward ensuring more patients can benefit from advanced diagnostic technologies.
A Call to Action
The advancements in Alzheimer’s diagnostics and treatment represent a beacon of hope, but their success hinges on early detection. Patients, caregivers, and healthcare providers must work together to recognize the signs of cognitive impairment and seek evaluation promptly.

CMS Expands Coverage for PET Imaging in Alzheimer’s Diagnosis: A Game-Changer for Early Detection
The Centers for Medicare & Medicaid Services (CMS) has taken a significant step forward in the fight against Alzheimer’s disease by expanding coverage for amyloid PET imaging outside of research protocols. This decision marks a pivotal moment in improving early diagnosis and treatment for millions of Americans affected by this debilitating condition.
The importance of Early Detection
Alzheimer’s disease, the most common form of dementia, affects over 6 million Americans, with numbers expected to rise as the population ages. Early detection is critical for managing the disease, as it allows for timely interventions that can slow progression and improve quality of life. Amyloid PET scans, which detect amyloid plaques in the brain—a hallmark of Alzheimer’s—have emerged as a powerful diagnostic tool.
Previously, Medicare coverage for these scans was limited to research settings, creating barriers for patients and healthcare providers. The new CMS policy removes these restrictions,enabling broader access to this advanced diagnostic technology.
The Role of Healthcare Professionals
While this policy change is a major advancement, healthcare professionals (HCPs) play a crucial role in ensuring its success. Proactive conversations between HCPs, patients, and their families are essential for identifying early signs of cognitive impairment.
as part of the Medicare annual wellness exam, HCPs are encouraged to perform cognitive exams for patients aged 65 and older. These exams help establish a cognitive baseline or assess for impairment if symptoms are reported or observed. For patients showing signs of cognitive decline, further evaluation—such as blood-based biomarker tests or referrals to specialists—might potentially be warranted.
A Call to Action for HCPs
Dr.Anthony “Nino” Sireci, Senior Vice President of Diagnostics Development at Loxo Oncology and Eli Lilly and Company, emphasizes the importance of HCPs taking the lead in these conversations.A board-certified Clinical Pathologist and practicing molecular pathologist, Dr. Sireci has extensive experience in personalized genomic medicine. He is also an active member of the Association for Molecular Pathology (AMP), the College of American Pathologists (CAP), and the American Medical Association (AMA).
“Change begins with healthcare professionals,” says Dr.sireci. “Encouraging patients to speak up and take a proactive approach to addressing cognitive impairment is key to improving outcomes.”
