Alzheimer’s disease (AD) is the most common cause of dementia. Nowadays, 50 million people worldwide suffer from this neurodegenerative disease, and its prevalence is expected to be quadrupled. Although this sickness has no cure, exact and early finding techniques are significant to slow its encouraging and for the improvement of new medications.

The improvement of cerebrum imaging procedures has made conceivable to get essential data of patients in a painless manner that supplements clinical assessments. Past examinations have utilized a wide scope of imaging strategies to describe AD. Some of them depend on useful data given by Single Photon Emission Tomography, Positron Emission Tomography or practical Magnetic Resonance. Different investigations utilized physical data removed from underlying MRI, like proportions of cortical thickness, voxel-based morphometry or volume proportions of explicit mind locales
