A professor in the US has produced a study suggesting Alzheimer's affects men and women in different ways, a revelation that could lead to better treatment of the disease.
Dr Maria Spampinato is a medical researcher at the University of Southern California and lead led a five-year study of over 100 people with mild cognitive impairment, US newspaper the Post and Courier reports.
The team compared MRI scans taken at the point of diagnosis with those from 12 months before and after to come to some conclusions about the condition.
They found that there are more instances of areas of the brain wasting away in the months leading up to diagnosis in women than there are in men. It was also shown that the areas of the brain that are affected differ between the two sexes.
Although the damage was discovered to be occurring earlier in women, the study did show that men later suffer the same amount of brain atrophy but in a shorter time-frame.
Dr Spampinato said: "You don’t expect those differences in rate of loss. I was surprised."
