Sydney: Researchers have discovered that a shrinkage in the brain is the reason why some people with dementia are compulsive overeaters, paving the way for better diagnosis and new treatment for the disease.The research, led by Olivier Piguet from Neuroscience Research Australia, shows for the first time that some people with dementia have deterioration in the brain region that controls hunger.
A Neuroscience Research Australia study looked at MRI brain scans of a group of people with FTD as well as post-mortem brain tissue of another group with the disease."We found that the more pronounced their eating problem, the more severe the shrinkage in the back section of the hypothalamus," Piguet says.He also found that people with particularly severe shrinkage in this region also tended to have unusual deposits of a type of protein in their brains called TDP-43."This suggests to us that someone with FTD who has severe eating problems is likely to have this type of abnormal protein in their brain," the researcher said.IANS
