Grill, PhD Professor, Psychiatry & Human Behavior School of Medicine Professor, Neurobiology and Behavior School of Biological Sciences University of California, Irvine MedicalResearch.com: What is the background for this study? Response: Alzheimer’s disease is a major public health challenge. More than 6 million Americans have the disease, which causes cognitive problems and eventual dependence on others for daily function. Scientists understand that the disease begins in the brain years before memory and other thinking problems begin and the AHEAD Study aims to intervene in this window of time, to see if a drug that targets these brain changes can delay or prevent symptoms of the disease.

[caption id="attachment_57900" align="alignleft" width="165"]Henry Mahncke, PhD Chief Executive Officer Posit Science Dr. Mahncke[/caption] Dr. Mahncke earned his PhD at UCSF in the lab where lifelong brain plasticity was discovered. At the request of his academic mentor, he currently leads a global team of more than 400 brain scientists engaged in designing, testing, refining, and validating the computerized brain exercises found in the BrainHQ app from Posit Science, where he serves as CEO. Earlier this year, MedicalResearch.com interviewed Dr. Henry Mahncke about the BRAVE Study he led, which showed a digital health app (BrainHQ) was effective in addressing chronic cognitive issues in servicemembers who had been diagnosed with “mild” Traumatic Brain Injury. This week, MedicalResearch.com interviews Dr. Mahncke again about a new independent study among civilians showing similar results in patients with all kinds of Brain Injuries. MedicalResearch.com: What is the background for this study? Response: The Centers for Disease Control (CDC) estimates that about 5.3 million people currently live with a chronic disability from a Traumatic Brain Injury (TBI). While most people who suffer a blow to the head recover in a couple days or weeks, for some (estimated as high as 15 percent) the injury persists with a variety of life-disrupting symptoms, including impairments in cognitive abilities, behavior, emotions, and motor function affecting work, relationships, and daily function. TBIs have been the signature injury of recent wars. Nearly 400,000 service members have been diagnosed with TBIs, of which 82% were diagnosed with so-called “mild” TBIs from concussions and blast injuries. More than a decade ago, we began being asked by military and Veterans organizations, to study whether our brain exercises – which had shown positive effects in measures of cognition, everyday function, mood, and motor function in healthy older adults – could have an impact on people with chronic symptoms from TBIs. We talked earlier this year, when an 83-person, gold-standard, randomized controlled trial on mTBI (called the BRAVE Study) announced quite positive results from using BrainHQ exercises. That study was funded by the Department of Defense and run as five military and Veterans medical centers. The BRAVE Study found the BrainHQ group showed a statistically and clinically significant improvement on a standard measure of overall cognitive function (compared to a computer games control), and this benefit persisted for at least 12 weeks after training completed. Cognitive function improvements were nearly four times larger in the BrainHQ group than the control (as measured immediately following training) and grew to nearly five times larger (when measured again 12 weeks after training ended). On average, participants in the BrainHQ group improved on the cognitive performance composite measure by 24 percentile ranks – as though they went from the 50th percentile to the 74th percentile. One large question left unanswered from the BRAVE study was whether this approach might also work for other categories of TBIs, such as moderate and severe TBIs. A new study from independent researchers at NYU answers that question.

Response: We followed almost 200,000 long-distance skiers for up to two decades and investigated how many of these skiers were diagnosed with anxiety disorders compared to people of the same sex and age in the general population. In total, the study included almost 400,000 people. (Previous studies have shown that Vasaloppet skiers are significantly more physically active than the general population.)

MedicalResearch.com Interview with: [caption id="attachment_57967" align="alignleft" width="80"]Prof-Mika-Kivimaki Prof Kivimaki[/caption] Prof Mika Kivimaki PhD Director, Whitehall II Study Dept. of Epidemiology University College London MedicalResearch.com: What is the background for this study? Response: The Lancet 2020 Commission on Dementia Prevention, which is the most comprehensive and up-to-date review on the evidence in this field, did not list cognitive stimulation in adulthood as a protective factor against dementia. This was because trials results are inconsistent and observational studies suggest that leisure time cognitive activity does not reduce risk of dementia. However, it was unclear whether the reason for modest findings is that the decrease in brain plasticity with age prevents cognitive activities across adult life from conferring protection against dementia, or, in the case of interventions, that the cognitive stimulation studied has not been intensive or engaging enough to preserve cognitive function. To address this question, we decided to focus on cognitive stimulation at work rather than leisure time cognitive activity or cognitive interventions. We thought that this approach would allow us to detect an effect, if there is one, because exposure to cognitive stimulation at work typically lasts considerably longer than cognitively stimulating hobbies or cognitive interventions. We contacted 13 cohort studies in Europe which had data on cognitive stimulation at work. Seven had also a dementia follow-up and were selected to our analyses, a total of 107 896 dementia-free participants from the UK, France, Sweden and Finland. Follow-up of incident dementia varied between 13.7 to 30.1 years depending on the cohort. 1143 people developed dementia during this follow-up.

MedicalResearch.com Interview with: [caption id="attachment_57957" align="alignleft" width="200"]Annakaisa Haapasalo Dr. Haapasalo[/caption] Annakaisa Haapasalo, PhD Adjunct Professor Research Director (Associate Professor A.I. Virtanen Institute for Molecular Sciences Molecular Neurodegeneration University of Eastern Finland | UEF |   MedicalResearch.com: What is the background for this study? At what age might these changes be present? Response: Our research team is interested in understanding the underlying disease mechanisms and developing biomarkers for frontotemporal dementia (FTD). FTD is the second most common cause of dementia in the working age population. Presently, no efficient therapies exist for FTD, it is challenging to diagnose, and the disease mechanisms of different types of FTD remain largely unclear. We are especially interested in FTD associated with the C9orf72 repeat expansion because it is the most common genetic cause of frontotemporal dementia and exceptionally prevalent in Finnish FTD patients. Many current studies of FTD and C9orf72 repeat expansion have largely concentrated on examining neurons, as these are the principle CNS cells that are affected in neurodegeneration. Neurons are also one of our key research interests, but obtaining neurons directly from living patients is difficult in many ways. Therefore, we became interested in exploring the FTD patient skin fibroblasts with the idea in mind that they might represent more easily accessible patient-derived cells than neurons for trying to decipher disease mechanisms of FTD. Moreover, we were interested in finding out if these cells show any specific alterations or deficiencies that could be utilized later on in biomarker studies or testing drug effects.

This week, MedicalResearch.com interviews Dr. Mahncke about a new study, with breakthrough results for service members and Veterans grappling with the signature injury of recent wars. MedicalResearch.com: What makes this study newsworthy? Response: As the last troops come home from Afghanistan, the battle is not over for many who served and continue to grapple with the signature injury of recent conflicts — mild Traumatic Brain Injury (or mTBI). Typically, such injures were caused by blasts or concussions, and they’ve been diagnosed in more than 300,000 service members. Most recover within a couple days or weeks, but for many — some estimate fifteen percent — physical, psychological, emotional, and cognitive problems persist for years. Such injuries often go untreated, because treatments focus on in-person, customized, cognitive rehabilitation, which can be helpful, but is costly, time-consuming, requires travel for treatment, and relies on the craft and expertise of the healthcare provider. Up until now, there’s been no effective intervention that’s highly-scalable and that can be delivered remotely. This study showed that remotely-administered BrainHQ computerized exercises improved overall cognitive performance in a population with very persistent cognitive issues. On average, patients in this study had cognitive issues for more than seven years. That means we finally have a tool shown effective in a gold-standard study that practitioners can employ in treating this large and underserved population, who sacrificed so much to serve our nation.

Response: There is concern over the association between participation in contact sports and later life risk of dementia and associated neurodegenerative disease. Much of this comes from observations of a specific form of neurodegenerative pathology - chronic traumatic encephalopathy (CTE)- linked to history of traumatic brain injury (TBI) and repetitive head impacts in autopsy studies of relatively small numbers of former athletes, including boxers and soccer players. Nevertheless, although this brain injury linked pathology is described, surprisingly little is known about what this might mean for later life health, specifically risk of dementia. In a previous study published from our programme of research looking at "Football's Influence on Lifelong health and Dementia risk' (the FIELD Study), we demonstrated that former professional soccer players had an approximately three-and-a-half-fold higher mortality from neurodegenerative disease than matched general population controls. However, these mortality data did not allow us to consider the relationships between varying head injury/impact exposure variables, such as player position and career length, and risk of neurodegenerative disease.

Response: During 2020 I was leading a study that sought to map the distribution of cognitive abilities and aspects of mental health across the UK population. The study generated a lot of interest because it was a collaboration with BBC2 Horizon, leading to ~390,000 participants. When the pandemic began to escalate in the UK a number of my colleagues at Imperial and elsewhere contacted me to note that the study could be used to investigate the impact of both the pandemic and direct illness on daily life, mental health and cognition. I had been thinking along similar lines so decided to add questionnaires about peoples' experiences with the pandemic and Covid-19 illness.

What are the common diseases of despair?  Response: Last decade, two Princeton economists, Anne Case and Angus Deaton, noted a precipitous rise in self-harming deaths (suicide, alcoholism, accidental poisonings, i.e., overdose) especially among poor whites in midlife with low educational attainment since the 1990s. These deaths were intimately linked with economic changes over the past several decades that have created more despairing conditions for the working class, made people more susceptible to seeking escape, numbness, and relief from physical, mental, and emotional pain. In recent years, the crisis has broadened, and we've seen rising excess mortality in other groups of working-class Americans as overall life expectancy has consistently fallen. Our team at Penn State College of Medicine and Highmark Inc. has previously examined “diseases of despair”, these being patients who are experiencing suicidal ideation or substance use issues and seeking out clinical care before they convert to "deaths of despair". We published a study in BMJ in 2020 showing a marked rise in these clinical diseases of despair across a sample of 12 million insurance carriers in Appalachia and the Rust Belt, again spanning across demographic boundaries. For this study, we honed in on high prevalence census blocks we had identified in our hospital's service area in central Pennsylvania and organized 4 focus groups in both rural and urban areas. We wanted to learn more about what people felt was driving despair in their communities, and what solutions might look like

Dr. Kelley[/caption] Mireille E. Kelley Ph.D. Staff Consultant for Engineering Systems Inc. MedicalResearch.com: What is the background for this study? Response: Youth and high school football players can sustain hundreds of head impacts in a season and while most of these impacts do not result in any signs or symptoms of concussion, there is concern that these repetitive subconcussive impacts may have a negative effect on the brain. The results of this study are part of an NIH-funded study to understand the effects of subconcussive head impact exposure on imaging data collected at pre- and post-season time points. The present study leveraged the longitudinal data that was collected in the parent study to understand how head impact exposure changes among athletes from season to season and how that relates to changes measured from imaging.

Response: My research focuses on understanding the link between the modifiable risk factors (such as diet, sleep and exercise) and mental distress. In this study, adults of different age-groups (18 years and older) were followed for 4 weeks.  Participants recorded their dietary intake, sleep quality, exercise frequency, their physical and mental wellbeing on a daily basis. Another research interest of mine is to assess these factors in relation to sex (different brain morphology) and age-groups (based on brain maturity). The rationale of this categorization is that brain morphology and brain development vs maintenance and repair may require a different repertoire of food and environmental factors. Therefore, we also studied the sex and age-groups effect. We also added the season factor as one of our previously published studies showed a link between season and mental distress. Data were collected for 2 years during the summer and fall seasons.

Nation, Ph.D., Associate Professor of Psychological Science Institute for Memory Impairments and Neurological Disorders University of California, Irvin MedicalResearch.com: What is the background for this study? Response: Hypertension is a risk factor for cognitive decline and dementia, and treatment of hypertension has been linked to decreased risk for cognitive impairment. Prior studies have attempted to identify which specific type of antihypertensive treatment conveys the most benefit for cognition, but findings have been mixed regarding this question.  We hypothesized that antihypertensive drugs acting on the brain angiotensin system may convey the greatest benefit since they affect the brain angiotensin system that has been implicated in memory function.

MedicalResearch.com Interview with: Daimei Sasayama, M.D., Ph.D. Department of Psychiatry Shinshu University MedicalResearch.com: What is the background for this study? Response: The diagnosis of autism spectrum disorder (ASD) is increasing worldwide. A 2016 US survey reported a prevalence of 1.85% in 8-year-olds, and a birth cohort study in Denmark reported that the future cumulative incidence of ASD could exceed 2.8%. Our recent regional cohort study in Japan reported an even higher cumulative incidence of 3.1%. So we examined whether the cumulative incidence in our regional cohort represents the nationwide incidence in Japan.

Severinghaus Assistant Professor In Residence Anesthesia & Perioperative Care UCSF Medical Center MedicalResearch.com: What is the background for this study? Response: We have known for a while that, rarely, some older adults suffer substantial, durable cognitive decline after surgery, particularly after coronary artery bypass grafting (CABG) surgery; a larger proportion experience a decline in cognitive test performance which doesn't necessarily affect function, but which has caused concern among researchers.  This cognitive decline was attributed, in part, to the cardiac bypass pump. ​Many of the studies had methodological limitations which made it difficult to be sure that the cognitive change was due to surgery and not due more generally to heart problems or atherosclerotic disease, which may also imply cerebrovascular atherosclerosis. Using a large database of older adults who undergo regular cognitive testing, we identified individuals who underwent CABG and compared them to those who underwent percutaneous coronary intervention (PCI), a minimally invasive, non-surgical method of opening blocked coronary arteries.  This allowed us to model the rate of memory decline before surgery - which hadn't been done in previous studies - and compare it to the rate of memory decline after surgery in older adults who had serious heart disease (some of whom were treated with CABG, and some treated with PCI).

MedicalResearch.com Interview with: Kristina Aspvall | Psychologist, PhD Eva Serlachius MD PhD Adjunct professor Professor David Mataix-Cols, PhD Karolinska Institutet Department of Clinical Neuroscience Child and Adolescent Psychiatry Research Center Stockholm MedicalResearch.com: What is the background for this study? Response: The problem we were trying to solve is the shortage of specialist Cognitive Behavioral Therapy (CBT) for children and adolescents with Obsessive-Compulsive Disorder (OCD). CBT is the first line treatment for children and adolescents with OCD but is a highly specialist treatment rarely available outside large medical centres, typically located in big cities. Previous work by our group and others had shown that it is possible to deliver CBT via the internet in the form of a self-help programme with minimal support from a clinician. The clinician can be located anywhere and provide asynchronous support via a built-in messaging system. Parental support is a key component of the treatment. In essence, the parents take over as the child’s main therapist, under the guidance of the expert clinician.

Response:     It remains unclear whether COVID-19 is associated with psychiatric symptoms during or after the acute illness phase. Being affected by the disease exposes the individual to an uncertain prognosis and a state of quarantine. These factors can predispose individuals to the development of mental symptoms during or after the acute phase of the disease. There is a need for prospective studies assessing psychiatric symptoms in COVID-19 patients in the post-infection period.

Tiffany Braley, MD, MS Associate Professor

University of Michigan, Medical School Department of Neurology Department of Nutritional Sciences Ann Arbor, MI 48109-5845 MedicalResearch.com: What is the background for this study? Response: Dementia is a public health crisis that affects more than 6 million Americans.  As no treatments to effectively reverse dementia are currently available, interest has shifted toward modifiable risk factors for dementia, which may offer a critical window for prevention or intervention. Recent research suggests that obstructive sleep apnea (OSA) is a common, yet undiagnosed, risk factor for cognition impairment in older adults. However, few studies have examined whether treatment of OSA with positive airway pressure (PAP) therapy could protect those with OSA against developing dementia, says principal investigator, Dr. Tiffany Braley, MD, MS, Associate Professor of Neurology from the University of Michigan. To address this gap, Dr. Braley and Dr. Galit Levi Dunietz, PhD, MPH, Assistant Professor and sleep epidemiologist, examined associations between PAP therapy use and 3-year incidence of Alzheimer’s disease, mild cognitive impairment (MCI), or other forms of dementia (DNOS, “dementia not otherwise specified”).

KAMER, DMD, MS, PhD Associate Professor Periodontology and Implant Dentistry NYU Dentistry Dr. Kamer[/caption] ANGELA R. KAMER, DMD, MS, PhD Associate Professor Periodontology and Implant Dentistry NYU Dentistry MedicalResearch.com: What is the background for this study? Response: The accumulation of amyloid β plaques and neurofibrillary pathology in the brain are pathognomonic to Alzheimer's disease (AD). Brain amyloid deposition begins decades before cognitive dysfunction and is thought to be the first AD pathological feature followed by tau tangle accumulations and other pathologies. The mechanisms by which brain amyloid develops are incompletely understood although inflammation and bacterial imbalances (known as dysbiosis) of the gut and oral cavity may be involved. Periodontal disease affecting more than 50% of elderly is an inflammatory, chronic condition characterized by periodontal tissue destruction and bacterial imbalances. Using PET studies, we showed previously that measures of periodontal destruction were associated with brain amyloid retention in the brain [1]. In this study, we sought to investigate whether subgingival (under the gum line) bacteria associated with Alzheimer’s disease specific pathology, namely amyloidosis and tauopathy.

Response: This 78 week phase 2 study tested donanemab in patients with early Alzheimer’s disease. Donanemab is a an anti-amyloid monoclonal antibody that targets the N3 pyroglutamate epitope.  MedicalResearch.com: What are the main findings? Response: The drug produced a substantial lowering of amyloid plaques and showed a slowing in cognitive decline. Key innovations included using PET scans to ensure all patients were amyloid positive and had a moderate level of tau build-up and switching from drug to placebo once the amyloid level was below the expected cut-off for Alzheimer’s disease. There were no new safety signals. The main side-effect was amyloid-related imaging abnormalities (ARIA) that have been seen with other anti-amyloid treatments. ARIA is managed with regular safety MRI scans.  Donanemab is now being tested in a larger phase 3 trial that could lead to regulatory approval.

Wagner PhD University of California, San Diego Department of Neurosciences Professor in Residence School of Medicine, Medical Teaching Facility Room 150 La Jolla, California 92093-0624  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: Amyloid plaques are pathological hallmarks of Alzheimer’s disease (AD)—clumps of misfolded proteins that accumulate in the brain, disrupting and killing neurons and resulting in the progressive cognitive impairment that is characteristic of the widespread neurological disorder.  Amyloid plaques are composed of small protein fragments called amyloid beta (Aβ) peptides. These peptides are generated by enzymes called β-secretase and γ-secretase, which sequentially cleave a protein called amyloid precursor protein on the surfaces of neurons to release Aβ fragments of varying lengths. Some of these fragments, such as Aβ42, are particularly prone to forming plaques, and their production is elevated in patients with mutations predisposing them to early-onset AD. Several attempts have been made to treat or prevent AD using drugs that inhibit either β-secretase or γ-secretase, but many of these drugs have proved to be highly toxic or unsafe in humans, likely because β-secretase and γ-secretase are required to cleave additional proteins in the brain and other organs. Instead, Wagner and colleagues investigated the therapeutic potential of drugs known as γ-secretase modulators or GSMs, which instead of inhibiting the γ-secretase enzyme, slightly alter its activity so that it produces fewer Aβ peptides that are prone to form plaques while continuing to duties cleaving other protein targets. “GSMs offer the ability to mitigate mechanism-based toxicities associated with γ-secretase inhibitors,” said Wagner.

Response: There have been multiple studies investigating potential sex differences in outcomes from concussion which have sometimes had conflicting results with some studies indicating that females take longer to recover than males and some studies reporting no difference in recovery between females and males, with most of these studies being conducted either retrospectively or prospectively in smaller cohorts. This large-scale multi-center prospective study in collegiate athletes provided an opportunity to compare females and males across comparable sports to examine both potential intrinsic or biologic factors (sex differences) or extrinsic (environmental or gender differences) that contribute to outcomes.
