In recent years it became clear that people with diabetes face an ominous prospect -- a far greater risk of developing Alzheimer's disease. Now researchers at The City College of New York (CCNY) have shed light on one reason why. Biology Professor Chris Li and her colleagues have discovered that a single gene forms a common link between the two diseases.
They found that the gene, known to be present in many Alzheimer's disease cases, affects the insulin pathway. Disruption of this pathway is a hallmark of diabetes. The finding could point to a therapeutic target for both diseases. The researchers report their finding in the June 2012 issue of the journal Genetics.
"People with type 2 diabetes have an increased risk of dementia. The insulin pathways are involved in many metabolic processes, including helping to keep the nervous system healthy," said Professor Li, explaining why the link is not far-fetched.
Although the cause of Alzheimer's is still unclear, one criterion for diagnosis of the disease after death is the presence of sticky plaques of amyloid protein in decimated portions of patients' brains.
