And now, for $399, plus a $13 “physician service fee,” they can order a blood test that promises to help assess their risk of Alzheimer disease. In a press release, Quest Diagnostics noted that its AD-Detect Test for Alzheimer Disease is the first blood test available for consumers to purchase that measures a biomarker linked to the most common form of dementia. The test…

Willie B. Thomas/Getty Images Treating high blood pressure in older adults reduces their risk of dementia, an analysis of previous research shows, providing more evidence that heart health and brain health are intimately connected. In a new meta-analysis, published Sept. 12 in JAMA Network Open, researchers found that older adults with untreated high blood pressure were 42% more likely to develop dementia during the study period compared to healthy older adults. This was true even among 70- and 80-year-olds. “The study suggests that successful treatment of hypertension might bring down the risk of developing dementia to the level of individuals with no hypertension,” said Dr. S.…

Dear Colleagues, I am thrilled to announce and celebrate four outstanding individuals who have been honored with Lauds & Laurels awards. These individuals have not only excelled in their respective fields but have also demonstrated exceptional dedication and a relentless pursuit of excellence. Dr. Tamera Hatfield, PhD, an alumna of our school, has been awarded the Distinguished Alumni award. Dr. Hatfield’s academic journey at the School of Biological Sciences and the UCI School of Medicine has culminated in her becoming a board-certified, fellowship-trained UCI Health obstetrician. Andrea Wasserman, the Chief Administrative Officer of the UC Irvine Institute for Memory Impairments…

Small trial of Bemdaneprocel, which aims to replace dopamine-producing neurons, raises hope for treatment The loss of dopamine-producing neurons with Parkinson’s causes symptoms including a tremor, slow movements and muscle stiffness. Photograph: David Davies/PA Scientists have reported early success in a trial of an experimental cell therapy for Parkinson’s disease, raising hope for patients. Bemdaneprocel therapy is at an early stage, and the year-long trial involved just 12 patients, but the positive outcome is viewed as significant after decades of setbacks in the hunt for an effective treatment. Developed by BlueRock therapeutics, a subsidiary of the pharmaceutical company Bayer, it…

Downtown Los Angeles seen in the hazy distance. Photo: Caroline Brehman/Zuma Press Smoggy air can hurt your health even after the smoke has cleared. But you can lower your risk. Some animal research suggests that fine particles can make their way into the brain, says Masashi Kitazawa, an associate professor of environmental and occupational health at the University of California, Irvine. He recently co-wrote a study that found that older mice who were exposed to polluted air were at an increased risk of developing Alzheimer’s disease than those who got purified air. Even the younger mice who were exposed to polluted…

More Asian Americans, Native Hawaiians and Pacific Islanders sought for studies on aging UCI’s Joshua Grill is one of three principal investigators for the National Institute on Aging grant that will fund CARE 2.0. Steve Zylius / UCI August 2, 2023—With a $16 million grant from the National Institute on Aging, the University of California, San Francisco and the University of California, Irvine will work with community partners to improve the representation of Asian American, Native Hawaiian and Pacific Islander adults in research on aging, caregiving, and Alzheimer’s disease and related dementias. The new project builds on a previous effort…

Quest Diagnostics recently announced the launch of a direct-to-consumer blood test to detect amyloid plaques in the brain. The test examines the ratio of Ab42/Ab40 in the plasma. Based on the Quest website, the test results are provided in numeric fashion, as well as based on categories of low, intermediate, and high risk of amyloid presence in the brain (with lower numbers on the plasma Ab ratio associated with higher likelihood of amyloid being present in the brain). As can be seen on the website, there is a high degree of overlap on test results among those with elevated compared…

REUTERS/Alyssa Pointer Dr. Joshua Grill, a University of California, Irvine, Alzheimer's researcher, who collaborated with Eisai and other researchers to analyze two trials for Leqembi and two for an earlier anti-amyloid drug, also found that Black, Hispanic and Asian people were more likely to be screened out of clinical trials because the amount of amyloid…

From cutting-edge research on Alzheimer’s disease to an innovative effort to include environmental justice and community engagement in climate and sustainability science research and education, University of California, Irvine scholars, scientists and physicians are blazing new paths to help change the world. And their impact keeps growing. In fiscal 2022-23, which ended June 30, UCI received the most research funding in campus history: $653 million in grants and contracts. Awards from federal and state agencies, leading foundations and forward-thinking companies rose by 12.7 percent over the 2021-22 total of $580 million, reflecting strong support for UCI’s top-ranked faculty, first-rate facilities,…
