(oxidative stress - neurons in the brain to die)

Simply put, that same "browning" process-known as oxidative stress-happens in the brain as Alzheimer's disease sets in. The underlying cause is believed to be improper processing of a protein associated with the creation of free radicals that cause oxidative stress.

Now, a study by researchers in the University of Georgia College of Pharmacy has shown that an antioxidant can delay the onset of all the indicators of Alzheimer's disease, including cognitive decline. The researchers administered an antioxidant compound called MitoQ to mice genetically engineered to develop Alzheimer's.

"The brain consumes 20 percent of the oxygen in the body even though it only makes up 5 percent of the volume, so it's particularly susceptible to oxidative stress," said Franklin, coauthor of the study along with Meagan McManus, who received her Ph.D. in neuroscience from UGA in 2010. The UGA researchers hypothesized that antioxidants administered unsuccessfully by other researchers to treat Alzheimer's were not concentrated enough in the mitochondria of cells. Mitochondria are structures within cells that have many functions, including producing oxidative molecules that damage the brain and cause cell death. Continue to read: medicalxpress.com
