According to some doctors, 2015 could be the most promising year for fighting Alzheimer's disease and dementia.

Since 2003, the FDA has not approved any new medicine for the treatment but now it can be changed with the study that is in progress in Boston.

The Boston University Alzheimer's Disease Center and Boston Medical Center are participating in many trials and studies, involving one that brings significant hope.

According to the researchers, the Noble Study is going to test the effects of a drug which is known as T-817MA. At present, only five drugs have received approval to treat Alzheimer's disease.

Those medicines are meant to slow down early symptoms in a small number of people. T-817MA is for people who are already having a degree of dementia. According to experts, it might change the course of Alzheimer's disease.

According to Dr. Robert Stern, director of the Alzheimer's Disease Center, this study is one of the important approaches to try slow down the disease in person who is already at a point of being at moderate stage of dementia. Stern said that there is a possibility that T-817MA can protect brain cells from destruction of Alzheimer's disease that leads to dementia.

"The changes in the brain in Alzheimer's disease start maybe 20 years before the first symptoms and then get worse and worse as the disease gets further along”, said Stern. Adding to it, Stern also said that if this drug shows positive results then it will slow that progression which can help the person to maintain a much better quality of life without deteriorating.
