Smell test identifies AD risk
Just when the medical community is becoming excited about PET for Alzheimer's disease, along comes a new nemesis, the scratch-and-sniff test. Apparently, in Alzheimer's, the nose knows.
Just when the medical community is becoming excited about PET for Alzheimer's disease, along comes a new nemesis, the scratch-and-sniff test. Apparently, in Alzheimer's, the nose knows.
Autopsy results have indicated that the nerve pathways involved in smell are affected at an early stage in the brains of Alzheimer's pa-tients. Researchers at Columbia University have pinpointed 10 specific odors that patients with early Alzheimer's cannot identify: clove, leather, lemon, lilac, menthol, natural gas, pineapple, smoke, soap, and strawberry. The inability to identify these specific odors predicted who would go on to develop AD, according to Dr. Davangere Devanand and colleagues, who presented the findings at the American Col-lege of Neuropsychopharmacology meeting in December.
Devanand had ear-lier found a global relationship between loss of smell and Alzheimer's. But knowing the specific odors involved can help physicians make a definitive diagnosis and start therapy earlier, he said.
Study Shows No Impact of Hormone Therapy on PET/CT with 18F-Piflufolastat in PCa Imaging
May 7th 2025For patients with recurrent or metastatic prostate cancer, new research findings showed no significant difference in the sensitivity of 18F-piflufolastat PET/CT between patients on concurrent hormone therapy and those without hormone therapy.
