Alzheimer's disease, a progressive neurodegenerative disorder of the brain, is a major cause of death around the globe. Clinical symptoms of the disease appear at later stages, however, modern brain imaging techniques have enabled us to non-invasively visualize the internal structures of the brain and identify structural and functional changes well before time. Early detection of the disease is crucial for the patient, care givers and relatives to cope with the situation as well as for medical practitioners to discover new drugs. A novel image processing based approach is proposed for early...

Ischemic stroke is the most commonly occurring type of stroke and the most communal cause for disability and death in the world. Apart from clinical tests, a lot of research is conducted on computer based automated techniques for ischemic stroke risk estimation. Ultrasound images of the carotid artery are used in noninvasive image based methods for stroke risk estimation. Carotid artery morphology, noise and artifacts in the ultrasound images can lead to false classification. In this book, we have proposed an automatic ischemic stroke risk estimation approach using carotid intima media...
