Alzheimer’s is a very common disease which affects some humans at old age. It is a disease that affects the brain cells causing memory loss and other effect that might lead to death. It is important to understand how the disease works over the brain and what are the changes that takes place in order to be able to cope with it.
A study done by CNRS, École pratique des hautes études and the University of Valencia was dedicated to understand the process of brain amendments that takes place. They were able to get a hole of 4000 MRI scans of both healthy people and others who suffer from Alzheimer’s. The team started analyzing and comparing the images which contained images of different stages of the disease and different age ranges.
Using the images from all the healthy participants (2,944), they were able to create a model average of the normal brain look and activities to reflect upon. Furthermore, this model was used to compare the rest of the scans with it. Two main brain parts which are associated with the disease showed a great change, including divergence in the hippocampus at ages earlier than 40 and the amygdala. The lateral ventricle in the brain will also observe a slight enlargement at early ages of the patient if they are viable for Alzheimer’s. The enlargement of the ventricle is normal for all humans, however, it tends to expand a bit more in patients.
