Alzheimer's disease afflicts mostly those in advanced age. Many believe that Alzheimer's disease starts late in life. A study though shows that Alzheimer's roots may go all the way back to the womb.

The study has found that Alzheimer's disease might start very early on for babies who do not have enough Vitamin A while still inside the womb. The findings have been based after experiments were done on lab mice. The study has been made by Dr. Weihong Song. Song is a professor of Psychiatry and Canada Research Chair in Alzheimer's disease.
