Study Stresses Need to Address Challenges in Early Alzheimer’s Diagnosis

Significant regional differences exist in the U.S. healthcare system when it comes to the diagnosis and administration of disease-modifying medicines for early-stage Alzheimer’s disease, according to a recent RAND analysis. According to the paper, enlisting primary care physicians in these initiatives may be essential to accelerating the distribution of novel therapies.

Between 2025 and 2044, more people might receive disease-modifying treatments and wait times for specialists could be greatly decreased if primary care physicians were given the authority to diagnose and determine whether a patient qualifies for therapy. 

According to the survey, primary care professionals are technically capable of conducting cognitive evaluations, but they frequently don’t because of conflicting demands and time constraints. The paper suggests creating new training programs for primary care physicians, raising reimbursement rates, and creating policies to simplify processes to address this problem. 

The paper also implies that improved patient triage using blood-based biomarker testing could help experts handle fewer cases. This method may help diagnose and treat Alzheimer’s disease more quickly and effectively. 

The states with the longest anticipated wait times for diagnosis are listed in the report; these states include Alaska, Arkansas, Idaho, Mississippi, Montana, Nevada, Oklahoma, and Wyoming. The main cause of these prolonged wait times is the low proportion of dementia specialists among individuals who are 50 years of age and older. In particular, the paper highlights that wait times in rural areas are three times longer than in urban ones. 

Senior policy researcher at RAND and the report’s principal author, Jodi Liu, emphasizes the significance of systemic barriers by pointing out that patients with early-stage Alzheimer’s may not benefit from treatments that could slow the disease’s course. Strategies to lessen the burden on experts in the assessment and diagnosis of cognitive impairment are recommended by the report. 

The research emphasizes how important it is to address the difficulties in identifying, diagnosing, and treating patients with Alzheimer’s disease in its early stages, particularly considering the impending release of medicines that modify the condition. An estimated 12.1 million Americans suffer with moderate cognitive impairment, which may be a sign of Alzheimer’s disease or other similar conditions. 

A significant advancement in slowing the progression of early-stage Alzheimer’s disease has been made with the U.S. Food and Drug Administration’s approval of two disease-modifying treatments (one with regular approval and one with accelerated approval). But there are still concerns over the cost, insurance coverage, and methods of administration of these treatments. 

RAND researchers used a simulation model to evaluate the regional capacity of the US healthcare system to provide Alzheimer’s disease-modifying treatments. The workforce needed for intravenous infusion treatments, the availability of PET scanners for diagnosis confirmation, the quantity of medical specialists, patient demand, and provider supply were all considered in this model. The study expands on past RAND research that looked at the healthcare system’s readiness prior to the practical application of these treatments.
