Stalked by the Fear That Dementia Is Stalking You The New York Times (Kaiser Health News) - Feb. 20, 2020 I spoke to half a dozen experts, and none was in favor of genetic testing, except in unusual circumstances. “Having the APOE4 allele does not mean you’ll get Alzheimer’s disease. Plenty of people with Alzheimer’s don’t have the allele,” said Mark Mapstone, a professor of neurology at the University of California, Irvine. “And conversely, plenty of people with the allele never develop Alzheimer’s.”

Orange County Business Journal - Feb. 17, 2020 Dr. Ruth Benca, who is chair of the Psychiatry and Human Behavior School of Medicine at the University of California, Irvine in 2018 restarted the UCI sleep center. She’s designed a new, 6,000-square foot facility in Newport Beach … and has recruited doctors from a variety of fields, such as Dr. Kevin Im, who won a 2014 national award for a sleep study, Dr. Rami Khayat, the center’s medical director and expert on the effects of sleep apnea on cardiovascular diseases, and Dr. Behrouz Jafari, an expert in pulmonology. “We’ve built this…

UCI MIND faculty member, Craig Stark, PhD was recently quoted in Science Magazine discussing the critical role scientists play in helping improve society. The article focuses on a push to better understand the science behind addiction, and how scientists are spreading evidence-based treatment knowledge through regional and national seminars. By regularly hosting seminars to gather scientific and legal experts, researchers can better inform the criminal justice system on how to improve substance abuse recovery rates in the incarcerated population. Dr. Stark, a neurobiologist who specializes in brain imaging at UCI, has presented at dozens of these legal seminars, speaking on…

Stewart Cohen/Getty Images NPR recently spoke on All Things Considered about the EXERT Study, a nationwide clinical trial of exercise led by Carl Cotman, PhD, UCI MIND's Founding Director, and Laura Baker, PhD, Associate Director of the ADRC at Wake Forest School of Medicine. The study involves an 18-month exercise program at the local YMCA for 65-89 year-olds with Mild Cognitive Impairment. Throughout the program, researchers look at participants' cognition, blood flow, atrophy (cell loss), and harmful protein accumulation in the brain. Researchers hope to learn about the clinical effect of exercise, as well as the scientific basis for their…

Contributed by Carl W. Cotman, PhD and Nicole C. Berchtold, PhD It is increasingly recognized that exercise builds brain health. At a fundamental level, brain health and function depend on the expression of the brain’s genes, the building blocks of cells. In a recent paper that appeared in the journal “Neurobiology of Aging” (2019), Drs. Carl Cotman, Nicole Berchtold and coworkers demonstrated that in the brains of healthy older people, exercise reprograms gene expression patterns to a more youthful state, even in cognitively normal people (75-100 yrs old). Genes that were particularly targeted are those that boost cellular energy production and build…

Contributed by Joan Steffan, PhD In a recent paper published in Proceedings of the National Academic of Sciences, colleagues and I show that a critical regulator of the immune system - called kinase IKKbeta - helps slow the onset of Huntington’s disease (HD) in mice, and this may be due to activation of a process called autophagy. Autophagy helps cells clean out and recycle their 'trash'. Accumulation of trash can occur as we age and when disease is present, so regular cleaning enabled by autophagy is critical to maintain cellular function. In HD, brain cell autophagy fails, leading to an accumulation of harmful proteins that…

Contributed by Bryce Mander, PhD The Food and Drug Administration (FDA) has recently required some sleep medications which are commonly used to treat insomnia to add black box warning labels. The reason for this decision is because there have been reported incidents of individuals engaging in activities that commonly occur during wakefulness during sleep while on these medications, including sleep walking, sleep driving, sleep eating, and sleep cooking. On rare occasions, these symptoms have resulted in serious injuries or life-threatening incidents, which has led to the inclusion of the black box label. The FDA has also issued a contraindication for…

The Atlantic - April 11, 2019. Kim Green, a neurobiologist at UC Irvine, notes mutant mice lacking microglia have broadly similar patterns of disorganization in their brains. These mice models essentially predicted what would happen in the human. He had just never expected to see a person without microglia. “It’s absolutely remarkable,” he says.

TIME - April 11, 2019. “Alcohol could be beneficial through biological mechanisms like increasing HDL cholesterol, affecting clotting mechanisms and blood platelets, or effects on the vascular system,” says Dr. Claudia Kawas, a professor of neurology at the University of California, Irvine whose research has found that some of the oldest-living adults tend to drink alcohol in moderation.

AARP - April 10, 2019. “A common situation is an older adult becoming concerned about their memory and taking a supplement to try to ward off dementia,” says Joshua Grill, director of the Institute for Memory Impairments and Neurological Disorders at the University of California, Irvine. “But in reality, if they saw their doctor, they might find out that another medical condition such as hypothyroidism, or a certain prescription medication, is causing symptoms and can be easily treated. They're just making things worse.” And if you do have dementia, he adds, you could start a drug treatment to relieve symptoms,…

Carl Cotman, PhD A study was recently published in the journal Neurology about physical activity's relation to Alzheimer's disease and cognition in older adults. NPR asked UCI MIND founding director Dr. Carl Cotman to comment on this impressive study, noting that exercise might "'offset the ill effects of brain degeneration.' He adds that lifestyle interventions such as an increase in physical activity and movement can be powerful even in the presence of disease."

Vivek Swarup, PhD, Assistant Professor of Neurobiology & Behavior UCI MIND faculty member, Dr. Vivek Swarup, and colleagues at UCLA, Takeda Pharmaceutical Co. Ltd. in Japan, Emory University School of Medicine, Harvard Medical School, and the Perelman School of Medicine at the University of Pennsylvania, published novel findings yesterday in Nature Medicine on two major groups of genes associated with Alzheimer’s disease and frontotemporal dementia and unraveled a novel microRNA, miR-203, as a master regulator of neuronal death. In human cell cultures containing AD-associated mutations, the researchers showed that certain experimental drugs altered the loss of brain cells associated with neurodegenerative disease. Dr. Swarup says, “I’m hopeful these important findings…

UCI MIND faculty member Dr. Mathew Blurton-Jones was awarded a $500,000 grant from Orange County Community Foundation to test 1200+ FDA-approved compounds for effectiveness in Alzheimer's disease treatment. His lab seeks to find the top 20 genes and drugs that safely prevent brain damage caused by microglia, which are critical immune cells in the brain that 'prune' unnecessary neuronal connections, or synapses. In the brains of people with Alzheimer's disease, damage can be caused by microglia 'overpruning' synapses, leading to loss of necessary connections. UCI News reports that Dr. Blurton-Jones and his team are "grateful to be the recipients of this…
