RESEARCH UPDATE
REVEAL Retreat
The Risk Evaluation and Education for Alzheimer’s (REVEAL) Study is a multi-site study evaluating the psychological and behavioral impact of genetic risk disclosure on first-degree relatives of AD patients. On September 9th and 10th, the REVEAL Study held its annual retreat in Boston. Attendees included investigators and genetic counselors from three collaborating sites – Cornell, Case Western, and Howard University – as well as three new distinguished collaborators: Dr. Deepak Bhatt (Cleveland Clinic), Dr. Jason Karlawish (University of Pennsylvania), and Dr. Ronald Petersen (Mayo Clinic), whose research on mild cognitive impairment is internationally recognized.
Flurizan
The Flurizan Study closed enrollment on September 1st after successfully recruiting 1684 participants nationwide; the BU ADC was one of the top enrollment sites, with 40 participants. All participants completing the 18 month trial are eligible for the open label trial and will receive the study drug and follow up.
False Memory
Alzheimer’s patients suffer from false memories - remembering things that never happened. In their study, “Episodic memory in Alzheimer’s disease: Separating response bias from discrimination” (Neuropsychologia 2006 44:2222-2232), Dr. Andrew Budson and colleagues examined patients’ false memory tendency, by observing how often they responded, “Yes, I’ve seen that before,” on a recognition memory test. Compared to healthy older adults, the patients showed worse memory and an abnormally liberal response bias (responding “yes” too liberally to test items). They concluded that as AD progresses, two distinct memory abnormalities develop: worse discrimination and a more liberal response bias.
APP and Klotho News
Dr. Carmela Abraham, Professor of Biochemistry, studies the normal biology of the Amyloid Precursor Protein (APP), the parent molecule for the amyloid beta peptide, a toxic protein implicated in AD. Recently, Dr. Abraham was awarded an Alzheimer’s Association grant to study the “Significance of APP dimerization in Alzheimer’s disease.” Dr. Abraham also investigates changes that occur during normal aging of the brain. In this project, Klotho, an anti-aging gene, was found to be decreased as a function of age. Mice lacking Klotho develop changes seen in human aging such as cognitive decline, arteriosclerosis, osteoporosis, hair loss and infertility. In contrast, mice with higher than normal Klotho levels have an increased lifespan and are more resistant to disease. Dr. Abraham received an anonymous foundation grant to reveal Klotho’s role in the young brain and find ways to increase its activity in the aging brain.
