Diagnosing Alzheimer’s: PET Scanning

This information is useful for adults and older adults

Alzheimer’s disease is the most common form of dementia, affecting 25 million people worldwide. Diagnosis has traditionally been difficult, based solely on clinical examination and medical history. In this video, Lawrence Saperstein, MD, a radiologist in the Department of Radiology & Biomedical Imaging at Yale Medicine, explains how positron-emission tomography (PET scanning) has completely revolutionized the evaluation process. PET Scanning uses radioactive material and a special camera to evaluate organ and tissue function. It gives doctors the ability to diagnose Alzheimer’s disease earlier than was previously possible.

Clinical Trials

New treatments for many conditions are tested in clinical trials, which ultimately bring lifesaving new drugs and devices to the patients who need them most. By participating in a clinical trial, you may get access to the most advanced treatments for your condition, and help determine their benefits for future patients.
