The IOA focuses on supporting research on aging and age-related diseases. The organization recently reported on new information from researchers at the University of Pennsylvania that may help improve early diagnosis and treatment of dementia.
Currently, the causes of dementia are not known, but genetics seem to play a role. In studying the brains of deceased patients, scientists have learned that there are certain proteins that are associated with various forms of dementia and that Alzheimer's generally leads to a loss of tissue in the memory regions of the brain.
Dr. David Irwin has said that PET scans performed early on a patient’s brain may reveal the accumulation of these proteins before symptoms set in, and early diagnosis and treatment has already been shown to slow the progression of dementia.
