A comparative study of brain volume changes in Alzheimer´s disease using MRI scans

Alzheimer´s (AD) is the most common form of dementia that negatively affects memory, thinking, behavior, and intellectual abilities in one´s daily life. The risk of AD increases with age 65 and older although it may appear in people who are in their 40s or 50s. AD has no current cure. There are many ongoing research studies to understanding and treating this disease better. AD, a slowly progressive brain disease, begins well before clinical symptoms emerge. A diagnosis of AD is usually made by primary care physicians based on patient´s medical and family history, psychiatric history, and history of cognitive and behavioral changes. Magnetic resonance imaging (MRI) is the most common imaging modality to use to identify brain changes. In this study, MRI scans of 10 individuals without AD and 10 individuals with AD are compared and analyzed based on brain volume. Measurements included the occipital lobe and hippocampal.
