Brain abnormalities seen on scans of adults with a gene mutation linked to Alzheimer’s disease have been found in brain scans of newborns with the same mutation, suggesting risk for the disease may develop in the womb for some, a study found.

Researchers at the University of North Carolina used an MRI to scan the brains of 272 newborns. The newborns also received a blood test to detect gene mutations that have been linked to conditions such as depression, bipolar disorder, anxiety, schizophrenia, and Alzheimer’s.
