Researchers use PET and MR to link Alzheimer’s and cold medication

Indiana University School of Medicine researchers used brain imaging to determine whether common cold and allergy medicines may shrink the brain and lead to an increased risk of Alzheimer’s disease.

The results of the study led the team of researchers to suggest older adults might want to avoid using some over-the-counter medications because the brain scans found lower metabolism and reduced brain sizes among those taking part in the study, according to ScienceDaily. Read more.
