Establishing the size of normal brain structures

Updated: Jan 2, 2021

A recent study published in the journal Neuroimage by Olivier Potvin, Abderazzak Mouiha, Louis Dieumegarde and Simon Duchesne analyzed brain scans from almost 2,800 healthy individuals in order to build a model of the normal size range of various brain structure in indivual of all ages. This kind of model, a bit like growth charts for kids, is a very important tool to detect if the atrophy (loss of tissue) in a specific region is due to normal aging or, conversely, possibly a pathology such as Alzheimer's disease.
