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.

As a child in the early 1980s, I was enamored with My Little Pony, the colorful plastic horse figurines with long manes. I also had the brand’s Show Stable, which was parked in our TV room and filled with my beloved ponies. But as I progressed through grade school, I eventually packed up my stable and forgot about the toys I once loved.   By late 2003, I hadn’t thought about my ponies for over 15 years. Then, VH1 ran a 1980s nostalgia show in which celebrities reminisced about bygone pop culture. An actress held up a My Little Pony figurine…

Overactivity in the hippocampus, likely tied to lack of inhibition, underlies some age-related cognitive decline. Targeting those circuits shows early promise in slowing memory loss. By Emily Singer December 9, 2021 As we get older, our memory begins to fail in predictable ways. We’re more likely to confuse similar memories, for example, forgetting whether it was little Tim or Samantha who threw the turkey leg across the room at Thanksgiving, and whether that happened the same year the dog snatched the sweet potato pie. In experiments in the lab, old people can easily remember very different objects but have a…

UCI MIND In The News: Dec 3 is International Day of Persons with Disabilities. So congratulations to Dr. Elizabeth Head of University of California, Irvine — Recognized as an Expertscape World Expert in Intellectual Disability: https://expertscape.com/ex/intellectual+disability

While aging is typically associated with cognitive decline, some individuals are able to diverge from the characteristic downward slope and maintain very high levels of cognitive performance. Prior studies have found that cortical thickness in the cingulate cortex, a region involved in information processing, memory, and attention, distinguish those with exceptional cognitive abilities when compared to their cognitively more typical elderly peers. Others major areas outside of the cingulate, such as the prefrontal cortex and insula, are also key in successful aging well into late age, suggesting that structural properties across a wide range of areas may better explain differences…

A blood test may be able to identify individuals at increased risk for developing Alzheimer’s disease symptoms, according to research presented at the Clinical Trials on Alzheimer’s Disease conference. The results came as part of the AHEAD study. Joshua D. Grill “The goal of this study is to stop Alzheimer’s disease before it begins — delaying or preventing symptoms in people at increased biological risk,” Joshua D. Grill, PhD, recruitment unit co-chair for the Alzheimer’s Clinical Trials Consortium, which helps oversee the AHEAD Study Recruitment and Retention Working Group, told Healio Psychiatry. “The latest advance is to use a blood test to improve the…

Overall, this nice series of experiments identifies yet another component of the sleep/wake regulatory system—the TRN—that is disrupted by Aβ and degenerated in AD. It is interesting that stimulating the TRN can impact Aβ. It is unlikely, however, that the TRN is the only stimulation target necessary, and that stimulating it would address all the sleep disruptions caused by Aβ and also tau pathology. AD pathophysiology impacts multiple different systems regulating sleep, including brainstem and hypothalamic nuclei, cortical nodes regulating slow wave expression, and even the hippocampus that regulates ripples, and coupling of slow waves, sleep spindles, and ripples. This…

Certain antihypertensive medications, particularly diuretics, are linked to lower Alzheimer’s disease neuropathology (ADNP) and other brain disease processes, new research shows.

The Women’s Alzheimer’s Movement – WAM spoke to University of California, Irvine’s Dr. Elizabeth Head about her latest research into the link between #Alzheimers and #DownSyndrome. Learn more about her study funded through the UCI MIND WAM Initiative. WAM: Why are we studying Alzheimer’s disease in people with Down syndrome? Is there a link? Dr. Head: Within the Down syndrome population, 95% of people have a full extra copy of chromosome 21. This chromosome contains a gene that is responsible for making the beta-amyloid protein that clumps together to form amyloid plaques in the brain, which is a hallmark of Alzheimer’s…

Neuroscientists have reportedly found how associative memories are made. The ability to be able to remember relationships that are made between unrelated items like odor and location, songs and events, is known as associative memory. The University of California, Irvine’s neuroscientists, have reportedly discovered some specific types of neurons within the brain’s memory center that are responsible for acquiring brand new associative memories. The findings of the study were reportedly published in the journal Nature, as also seen in news-medical.net. Psychologists reportedly started studying associative memory as early as the 1800s. Scientists now agree that the structures that are responsible…

The linked editorial from JAMA Neurology cites IMPACT-AD, the course co-led by UCI MIND, and work by The 90+ Study investigators, Maria Corrada, ScM, ScD and Claudia Kawas, MD. The systematic review by Mooldijk et al1 summarizes multiple areas in which the field of dementia research can improve clinical studies. Our Editorial will focus on ethnic and racial diversity (primarily in the US) and on age differences noted in the systematic review between population-based cohorts and clinical cohorts. We also share new and ongoing efforts in this area from the National Institute on Aging (NIA) and the broader National Institutes of…

Read more on this below: Since the FDA approved Aduhelm (aducanumab) on June 7, there has been considerable conversation, debate, and even backlash about the decision. It may seem difficult to keep up. Here is a recap of some of the most recent important events. The FDA granted Aduhelm what is known as “accelerated approval.” This means that the approval did not indicate that the drug has been adequately shown to benefit…

UCI School of Biological Sciences Dean Frank LaFerla is co-senior author of a study involving a new genetically engineered mouse model that, unlike its predecessors, is based on the most common form of Alzheimer’s disease. This could help lead to major strides in the fight to end this deadly disease! Dean LaFerla discusses his findings in a new podcast: https://www.bio.uci.edu/frank-laferla-podcast/

Contributed by Vivek Swarup, PhD The brain is made up of billions of cells that are tightly coordinated in complex neural circuitry and are ultimately responsible for manifesting our memories, emotions, and personalities: the very essence of being human. Alzheimer’s Disease (AD) is one of the most prevalent neurodegenerative disorders worldwide and results in cognitive decline and memory loss, and we presently do not have effective treatments for AD. There is a pressing need to deepen our understanding of AD, and by studying how individual cells are changing in disease, or identifying those that are resilient to such changes, we…

A crucial, overlooked question on the new Alzheimer’s drug: When should patients stop taking it? STAT News – June 24, 2021 “When we enroll families in studies of treatments like aducanumab, we try to educate them that they should not expect large improvements in cognition or function,” Joshua Grill, director of the Institute for Memory Impairments and Neurological Disorders at the University of California, Irvine, said in an email to STAT. The drug can’t stop disease progression, only potentially slow it, a change that he warns would likely be imperceptible. “If we can’t expect families to know if the drug…

People taking drugs that cross the blood-brain barrier experienced less cognitive decline June 21, 2021 The research conducted by Daniel Nation, UCI associate professor of psychological science, and Jean Ho, a postdoctoral scholar at the UCI Institute for Memory Impairments and Neurological Disorders, included more than 12,800 people over the age of 50 in 14 separate studies carried out across six countries. Steve Zylius / UCI Irvine, Calif., June  21, 2021 — A large-scale meta-analysis led by University of California, Irvine researchers provides the strongest evidence yet of which blood pressure medications help slow memory loss in older adults: those that can…

“My greatest concern is around people with families with Alzheimer’s disease,” said Joshua D. Grill, an Alzheimer’s researcher at the University of California at Irvine. “Few can afford the financial burden in the first place, let alone the additional costs of Aduhelm.” He said the cost of an amyloid PET scan was at least $5,000. “Doctors, families, even we researchers need more guidance,” Grill said. Spinal taps offer a more affordable way of determining amyloid levels, but some patients shy away from them.

KATU News: “We all have to do more because this is about the most important medical problem we face as a society today,” said Dr. Josh Grill, a member of the AHEAD Study leadership team and director of the UC Irvine Institute for Memory Impairments and Neurological Disorders.

MarketWatch As we age, our already limited attention span shrinks even more. So it takes extra discipline for seniors to stay curious. … Craig Stark, [professor of neurobiology and behavior], a memory researcher at University of California, Irvine, urges people who want to stay mentally sharp to “feed your brain novel information.” Curiosity can provide the impetus to gather that new information.

UCI MIND Faculty Member Christine Gall, PhD, a neuroscientist and professor of anatomy and neurobiology at UC Irvine’s School of Medicine, explains that our brains contain specialized cells, or neurons, that are responsible for sending and receiving information. Much like a circuit board in a computer, our brains create networks of neurons that transmit electrical activity when we engage in just about anything. These charges, AKA synapses, are critical for learning and memory.

Dr. Steven Tam, together with colleagues in the UCI School of Medicine’s Division of Geriatric Medicine & Gerontology at UC Irvine and Alzheimer’s Orange County are leading the effort to provide more accurate information and better resources to patients with AD and their caregivers.  To learn more, click here.

By the time they’re 40, most people with Down syndrome develop beta amyloid plaques in the brain — a key characteristic of Alzheimer’s disease. Scientists believe this is because they have an extra copy of chromosome 21, which carries an amyloid-producing gene. Many people with Down syndrome do develop Alzheimer’s disease, but some manage to avoid the devastating neurodegenerative consequences despite having these plaques in their brains. To learn more about the connection between Down syndrome and Alzheimer’s disease, UCI School of Medicine researchers are spearheading a major international research effort that will follow hundreds of adults with the syndrome…

On Monday, MPR News host Kerri Miller talked to two researchers, including UCI MIND investigator Claudia Kawas, MD, about what they’re learning about living to be 100. Do you have to win the genetic lottery to live an entire century? Or could research unlock the secret to living longer and living longer well? Listen here >

The UCI professor has dedicated her career to finding answers to a rare genetic disease’s most crucial questions. An estimated 30,000 genes make up the human genome, with an individual’s entire uniqueness created by genetic mutations. From tissues and blood as well as distinctive physical features, like eye and hair color to temperament and so much more, genes are the coded instructions for building an entire person. But sometimes those instructions contain errors and genes can mutate to form many different things, including diseases. One such disease, Huntington’s disease, is a rare, inherited disease triggered by a single genetic mutation…
