As the mean age of the world population rises and people\u27s life expectancies increase, the prevalence of Alzheimer\u27s disease will increase and will pose a threat to society in terms of the people affected and the money used. Current therapies are not adequate in that they are unable to extend life beyond a few months. This review will both overview the predominant hypotheses about how to approach the treatment of Alzheimer\u27s as well as discuss some of the treatments available and those in preclinical phases. Finally, we will discuss the ideas and recent research behind gene therapy and stem cell therapy as well as the new ways in which these two methods have been combined and could be combined in the future to create a more effective approach to treating Alzheimer\u27s
