Eye movement abnormalities flag brain health risk in ex-racing drivers
May 29, 2026
PET brain scans from the same individual with early signs of Alzheimer’s disease comparing two tau radiotracers: flortaucipir, shown at top, and the investigational tracer MK6240, shown at bottom. Areas of pathological tau accumulation appear in red. The MK6240 scan shows more extensive tau buildup, suggesting that this tracer may detect Alzheimer’s-related brain changes that are less visible with the standard tracer.
