Effective early detection of Alzheimer's and Dementia disease using Brain MRI Scan Images

It is known that the early detection of brain diseases significantly increases the life span and improves the quality of life in general. The human brain is a highly complex and non-linear system. As brain is involved in everything we do and everything we are, it is the most valuable part of the human body so it is very important for the physicians to know the stages of aging and changes that take place during these stages. Brain health is essential to all aspects of quality of life. Lower brain activity and blood flow causes greater risks for strokes or Alzheimer's disease. Brain need to be tuned, balanced and properly nourished to remain in excellent health. As we age our brain normally gets less and less active. People with Alzheimer's have a serious deterioration of brain function and often behaviour. Alzheimer's disease is the most common type of senile dementia. In this paper we discuss the causes of Alzheimer's and dementia diseases and various techniques that can be effectively utilized for their detection. And how magnetic resonance imaging (MRI) can detect changes in cerebral blood flow and blood oxygenation is presented.
