LOS ANGELES (Ju3. 13, 2014) — A noninvasive optical imaging device developed at Cedars-Sinai can provide early detection of changes that later occur in the brain and are a classic sign of Alzheimer’s disease, according to preliminary results from investigators conducting a clinical trial in Australia. “In preliminary results in 40 patients, the test could differentiate between Alzheimer’s disease and non-Alzheimer’s disease with 100 percent sensitivity and 80.6 percent specificity, meaning that all people with the disease tested positive and most of the people without the disease tested negative. The optical imaging exam appears to detect changes that occur 15-20 years before clinical diagnosis. It’s a practical exam that could allow testing of new therapies at an earlier stage, increasing our chances of altering the course of Alzheimer’s disease,” said Shaun Frost, a biomedical scientist and the study manager at the Commonwealth Scientific and Industrial Research Organisation. CSIRO is Australia’s national science agency.
