The multidisciplinary team will focus on participant recruitment and retainment for Alzheimer’s disease and related disorders research Josh Grill, left, and Daniel Gillen will examine what role recruitment registries for ADRD research can play in overcoming exclusions to improve research outcomes. What is the best way to recruit participants to join a clinical studies registry, and can such registries help better diversify clinical research samples? These are two critical questions that UCI researchers are tackling with a new National Institutes of Health grant, “Recruiting and Retaining Participants from Disadvantaged Neighborhoods in Registries.” The work will be led by Joshua Grill, professor…

Findings will advance development of better early diagnostic tools, new treatment strategies “This project will capture a composite of disease features to expand our understanding of the brain circuits susceptible to aging and Alzheimer’s. Our findings will facilitate the development of more effective early diagnostic tools and the discovery of new therapies,” says UCI’s Xiangmin Xu. Steve Zylius / UCI The University of California, Irvine has been awarded a five-year, $14 million grant from the National Institutes of Health to study brain circuits that are susceptible to aging and Alzheimer’s disease. The research findings will advance the development of early…

In a blunt rejection of current norms, two leaders of biomarker disclosure research argue research participants should have the opportunity to know whether they have biomarkers of Alzheimer’s disease . Biomarkers, or biological indicators of a disease, are essential to the study and diagnosis of Alzheimer’s and other diseases that cause dementia. Clinicians use imaging such as MRI and PET scans to measure biomarkers and make accurate diagnoses. Blood tests are fast becoming available too. The tests also allow researchers to develop targeted drug therapies. But in both clinical care and research, biomarker results are infrequently disclosed. Insurers typically do…

After decades of research into the causes and treatment of Parkinson's disease, UCI Health neurologist Dr. Claire Henchcliffe is hopeful that a new cell therapy can finally bring meaningful relief to patients with the progressive neurodegenerative movement disorder. A national expert on Parkinson's disease, she is one of a small group of U.S. researchers conducting a first-in-human clinical trial of transplanted stem cells engineered to replace dopamine-producing neurons that are destroyed by the debilitating and incurable condition. As the brain loses its ability to produce the potent neurotransmitting chemical, that leads to the tremors, stiffness, slowness and lack of coordination seen in Parkinson's patients. The…

The Collaborative Approach for Asian Americans and Pacific Islanders Research and Education (CARE): A recruitment registry for Alzheimer's disease and related dementias, aging, and caregiver-related research

Blood pressure variability is an emerging risk factor for cognitive decline and dementia, but mechanisms remain unclear. The current study examined whether visit-to-visit blood pressure variability is related to CSF Alzheimer’s disease biomarker levels over time, and whether associations differed by APOE ϵ4 carrier status.

Image Courtesy: AARP Through new developments in Alzheimer’s research, UCI scientists have uncovered evidence of P522R, a particular gene mutation that may aid in minimizing the risk of developing Alzheimer’s disease. Alzheimer’s disease is a progressive disorder that slowly deteriorates memory and thinking skills in the brain, eventually leading to a loss in the ability to complete simple tasks such as  facilitating a conversation or responding to a stimulus in the environment. With the discovery of the disease in 1906 by Dr. Alois Alzheimer, its causes today are focused on two suspects: plaques and tangles in proteins. Beta-amyloid, fragments of…

The Washington Post - April 7, 2022 The FDA approval of Aduhelm ignited a raging debate, with many doctors saying they would not prescribe the drug and several insurers declining to pay for it. Yet even with the uncertainty surrounding the drug, said Elizabeth Head, , at the University of California, Irvine, it is understandable why some families, especially those in which a loved one with Down syndrome faces an all but certain fate, “might believe doing something is better than doing nothing.”

"Much of neuroscience and study of brain diseases has focused on the brain's neurons. This study highlights that in addition to neurons, other brain cells, and especially immune cells, play crucial roles in brain health and disease," said Tallie Z. Baram, distinguished professor in the Departments of Anatomy & Neurobiology, Pediatrics, Neurology, and Physiology & Biophysics at the UCI School of Medicine. "Neuroimmune interactions are a novel, important avenue to understanding and treating several brain disorders and mental illness and have been linked by other UCI researchers to Alzheimer's disease."

First author Gianna Fote was recently interviewed by the Journal of Cell Science for a newly-published paper. She provided commentary on her team's new findings for UCI MIND: "In our recently published work we studied intracellular trafficking of Apolipoprotein E (APOE), a lipid-carrying protein. The APOE4 isoform of this protein is the biggest genetic risk factor for late-onset Alzheimer’s disease. We found that that APOE can be degraded by a process called autophagy, a process in which cellular waste is transported to an acidic organelle called the lysosome. The APOE4 isoform accumulates in the lysosome and causes increased induction of…

In collaboration with the @ucirvine (Principal Investigator, David Sultzer, M.D.)…

Managed Healthcare Executive - March 17, 2022 According to the CDC, about 5 million Americans have Alzheimer’s disease …. “These numbers are projected to increase because elderly individuals are the fastest-growing segment in the United States,” says Claudia H. Kawas, M.D., a professor in the Department of Neurology at the University of California, Irvine, School of Medicine. … The things known about dementia risk that are potentially modifiable are all related to general health and maintenance of health, says Kawas, noting the association between control of high blood pressure and cholesterol levels and a lower risk of dementia.

90+ Study: Learning from the oldest-old Researchers can learn a lot about how Alzheimer’s develops by studying people at increased risk. People older than age 90, or the oldest-old, are the fastest growing segment of the population in the United States and most of the world and have the highest rates of dementia. Remarkably, the oldest-old also have the highest rate of cognitive resilience and somehow avoid developing dementia despite having brain pathologies. This populations’ high rates of dementia, yet also resilience, make it an optimal group to study to understand the underlying causes of dementia. The 90+ Study, launched in…

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…

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.”

Our memories are imperfect treasures – dear to our hearts, but not necessarily accurate snapshots of reality. CNN's Chief Medical Correspondent Dr. Sanjay Gupta talks to neurobiologist Michael Yassa about how memories are stored in the brain, why we forget, and what we’ve gotten wrong about how it’s supposed to work. To help understand the mechanisms of memory, we meet a woman who remembers absolutely everything... and a man who can’t even recall what he ate for breakfast. Plus, actionable tips for how we can keep our memories sharp at any age.
