According to a report published in the Neurology, advanced brain imaging technology is able to identify the Alzheimer's disease at a very recent stage and before the symptoms could be witnessed.

The technology spots the certain chemical changes in the brain of people who are on the verge of developing the disease. For the research, 311 seniors aged between 70 and 80 were followed and chemical changes in their brain were studied by making them pass through "proton MR spectroscopy". The next stage was to test their memory, language and other cognitive abilities.

Results were compiled, and researchers noted that those participants who had high levels of amyloid-beta deposits and choline/creatine scored low marks on the test when compared to others who had lower levels of the chemicals.

Study author Kejal Kantarci said, "This relationship between amyloid-beta deposits and these metabolic changes in the brain are evidence that some of these people may be in the earliest stages of the disease”.

Kantarci said they need to further research so they could study the relationship between the chemicals in the brain and also know which of these individuals would develop the degenerative disease.
