Discover Magazine: Aging dogs can develop canine cognitive dysfunction (CCD), sometimes known as “doggie dementia.” The brains of dogs with CCD show only amyloid beta plaques, not tau tangles, but their symptoms are similar to the symptoms of dementia in humans, explains Elizabeth Head, director of the graduate program in experimental pathology at the University of California, Irvine. “They’ll forget how to signal that they need to go out,” Head says. “In the more severe stages of the disease, they can become incontinent and may not recognize people.” She points out that because dogs live closely with humans, any behavioral changes…

Contributed by Hayk Davtyan, Ph.D. and Christel Claes, Ph.D. While the word “mutation” may conjure up alarming notions, a mutation in brain immune cells serves a positive role in protecting people against Alzheimer’s disease. Now UCI MIND biologists have discovered the mechanisms behind this crucial process. Their paper appears in the journal Alzheimer’s and Dementia. The investigation centered on a variant of the PLCG2 gene, which makes the instructions for producing an enzyme important to brain immune cells called microglia. “Recently the mutation, which is known as P522R, was shown to lower the risk of developing late-onset Alzheimer’s,” said Hayk…

Renewal recognizes UCI's dedication to patient care and active engagement in research to develop new therapeutic approaches February 15, 2022 “Renewal of certification as a Huntington’s Disease Society of America Center of Excellence is very exciting, as this will help us expand our patient care and research. HD was one of the first diseases for which a genetic cause was determined and serves as a paradigm for research into other such diseases,” says Leslie Thompson, Ph.D., Donald Bren and Chancellor’s professor in the departments of psychiatry and human behavior and biological chemistry at the UCI School of Medicine. UCI has…

UCI MIND #InTheNews: Forbes: "According to UCI, the new center will involve collaborations across seven areas: SMART (statistics, machine learning-artificial intelligence) designs software to integrate and analyze health records, molecular data, and observation. This unit will be led by Daniel Gillen, professor and chair of statistics, and Zhaoxia Yu, associate professor of statistics... Precision omics generates, analyzes, and administers genomic, proteomic, and chemical data. It’s led by Suzanne Sandmeyer, professor of biological chemistry, and Leslie Thompson, the Donald Bren and Chancellor's Professor of psychiatry & human behavior at UCI... The institute will take special aim at diseases that heretofore have lacked effective treatments. “For many…

UCI MIND #InTheNews   @Seniors Matter - Feb. 9, 2022 “People who engaged in more healthy behaviors had a lower risk than people with fewer because all of these things matter, and when it comes to brain-healthy behaviors, more is more!” said Joshua Grill, PhD, a professor of psychiatry and human behavior at the University of California, Irvine. “So, we should all try to adopt as many brain-healthy behaviors as we can.”
