Early Detection of Alzheimer's - A Crucial Requirement

Abstract

Alzheimer's, an old age disease of people over 65 years causes problems with memory, thinking and behavior. This disease progresses very slow and its identification in early stages is very difficult. The symptoms of Alzheimer's appear slowly and gradually will have worse effects. In its early stages, not only the patients themselves but their loved ones are generally unable to accept that the patient is suffering from disease. In this paper, we have proposed a new algorithm to detect patients of Alzheimer's at early stages by comparing the Magnetic Resonance Images (MRI) of the patients with normal persons of their age. The progress of the disease can also be monitored by periodic comparison of the previous and current MRI.
