There is no second thought that Alzheimer's disease is a medical anomaly and perhaps this is what has caused so much of concern. On the same lines, it is said that the disease appears to affect human brain slowly. The disease moves from one brain cell to another.

For the study, the team led by Karen Duff, Professor of Pathology at Columbia University Medical Center, developed genetically engineered mice, which has an abnormal tau protein in the brain's entorhinal cortex. It took the team 22 months to track the movement of Tau, which moved from one region to another, thereby vindicating the claims made.

The team also declared that Tau plays a crucial role in instigating the disease. It is also being said that it could also be linked to dementia once a person dies. The same protein is told to be associated with other types of dementia, including frontotemporal lobe dementia, Parkinson's disease and Lewy body disorder.

There are good chances that researchers could make significant progress in the medical field after they track down how the abnormal protein moves in the brain. With the research making reverberations in the contours of the society, it is being believed that there could be some cure in the time to come for the same. There is a need for more research to be done to find out if there is any way out to stop the movement of the abnormal tau in the human brain.

It was said that Tau supplies nutrients to nerve cells in the brain in normal situation. However, it stops giving nutrients when damaged. "Mostly we wanted to mimic the early stages of Alzheimer's, because that could best give us some idea of where we could target therapeutically", said Duff.

While so much of research is being done on the disease, it is being believed that there could be some cure soon in future.
