US Scientists in the first week of April 2013 identified Genetic markers that could help in detecting Alzheimer’s disease. The research in Neuron detects mutations which impacts the building up of certain proteins in the brain. High levels of these phosphorylated tau (ptau) proteins increase the chance of Alzheimer’s disease in humans.
The recent scientific finding could help understand the changes that occur in the brains of Alzheimer's patients. This study helps scientists to better understand the way the brain changes when dementia develops.
One of the new gene variants was also shown to be linked to a small increased risk of developing Alzheimer's and a greater risk of cognitive decline. The scientists used genetic information from several people to carry out their experiment.UK experts said the study adds to the number of genetic markers that have been linked to the development of Alzheimer's disease.
