PET imaging links brain metabolism patterns to effectiveness of Alzheimer's disease treatment

Article excerpt

Researchers using PET imaging have identified a specific brain metabolism pattern that predicts which Alzheimer's patients will respond well to treatment. In a retrospective study presented at the Society of Nuclear Medicine and Molecular Imaging's 2026 annual meeting, patients displaying this pattern experienced stabilized cognitive performance after therapy, while those with different metabolism patterns showed significant cognitive decline. The finding could help clinicians identify candidates most likely to benefit from Alzheimer's interventions before treatment begins.
