Dr. Richard Isaacson was featured in a CNN video exploring a promising new blood test that could help identify Alzheimer’s disease years before symptoms begin. The segment highlights how blood biomarker testing may provide a simpler, more accessible alternative to PET scans and spinal taps for detecting the hallmark proteins associated with Alzheimer’s disease, while emphasizing that the test is still being evaluated for clinical use.

During the report, Dr. Isaacson explains how blood testing has the potential to expand access to early Alzheimer’s detection, allowing people at risk to be identified sooner and potentially benefit from lifestyle interventions and FDA-approved treatments during the earliest stages of disease. He also emphasizes that broader access to blood biomarkers could help democratize preventive brain health care.
