Author Interviews, Brain Injury / 16.11.2023

pexels-photo-7578808-medical-practitioner.webpIf you've been in a scrape and your noggin took a knock, playing it tough and shaking it off isn't the way to go. A traumatic brain injury (TBI), even one that seems no biggie, can be sneaky. At first, you might feel fine, but your brain's had a jolt, and it needs a look-over. Ignoring it? Bad move. That little headache or dizziness might be your brain's way of saying, "Hey, I'm not okay." Small signs like mood swings, sleep changes, or even just feeling "off" can be the early whispers of something bigger brewing. It's like ignoring a weird noise in your car's engine—let it go and you might just find yourself broken down on the highway of health.

The Domino Effect of Ignoring Symptoms

Let's talk about what happens if you shrug off those symptoms. A tiny injury can start a chain reaction. Before you know it, you could be dealing with big-time problems like memory issues, serious concentration hiccups, or even long-term disabilities. And here's the kicker: these troubles don't always show up on day one. They can sneak up on you, turning from "I'm fine" to "Why can't I remember my passwords?" in no time. Think about it—your brain runs the show, so even a small glitch can throw off the whole performance.

Alzheimer's - Dementia, Author Interviews, Genetic Research, JAMA, Stanford / 07.11.2023

MedicalResearch.com Interview with: Michael E. Belloy, PhD Department of Neurology and Neurological Sciences Stanford University, Stanford, California MedicalResearch.com: What is the background for this study? Response: Apolipoprotein E (APOE)*2 and APOE*4 are, respectively, the strongest protective and risk-increasing, genetic variants for late-onset Alzheimer disease. As such, one’s APOE genotype is highly relevant towards clinical trial design and Alzheimer’s disease research. However, most insights so far are focused on the associations of these APOE genotypes with Alzheimer’s disease risk in non-Hispanic white individuals. One important aspect of our work is that we really increased sample sizes for non-Hispanic Black, Hispanic, and East Asian individuals, so that we now have better understanding of the associations of APOE genotypes with Alzheimer’s disease risk in these groups. In complement, we also did the largest investigation to date on the role of ancestry on the associations of APOE genotypes with Alzheimer’s disease risk. The scale of our study was thus a critical factor in generating novel insights. (more…)
Author Interviews, Environmental Risks, JAMA, McGill, Mental Health Research / 06.11.2023

MedicalResearch.com Interview with: Niki Hosseini-Kamkar PhD Postdoc, McGill University MedicalResearch.com: What is the background for this study? Response: Our primary question was: Do adults with a history of childhood trauma have altered brain responses to psychological challenges? Previous evidence indicated that this can occur in laboratory animals, but it has been unclear whether it occurs in humans. (more…)
Author Interviews, Cognitive Issues, Nature, Pediatrics / 01.11.2023

MedicalResearch.com Interview with: Brenden Tervo-Clemmens, Ph.D. Assistant Professor Department of Psychiatry & Behavioral Sciences Masonic Institute for the Developing Brain Scholar, Institute for Translational Neuroscience University of Minnesota MedicalResearch.com: What is the background for this study? Response:      Both contemporary and historical theories of neurobehavioral development suggest executive functions (EF) mature through adolescence. These are often used in various contexts to try to demarcate the developmental boundaries of the adolescent period. However, the specific maturational timing of executive function, and the independence of various potential executive function subcomponents remain unknown. Building from prior investigations with relatively small datasets or narrow subsets of executive function measures, this work using four independent datasets (N>10,000) and 17 distinct executive function assessments provides a precise charting, multi-assessment investigation, and replication of executive function development from adolescence to adulthood.

Author Interviews, Cognitive Issues, Exercise - Fitness, JAMA / 01.11.2023

MedicalResearch.com Interview with: Peter A. Harmer, PhD, MPH, AT-Ret, FACSM Senior Associate Research Scientist Oregon Research Institute MedicalResearch.com: What is the background for this study? Response: Decline in various aspects of cognitive function, such as memory, executive function, and multitasking ability is common as we age. The rate and extent of decline varies among older adults but approximately 20% of those aged 65+ will experience clinically relevant mild cognitive impairment, which places them at increased risk of progressing to Alzheimer’s disease or related dementias. It is also associated with decreased mobility, increased risk of falls and impaired capacity for complex activities of daily living. Research has shown that physical and mental activity may attenuate the decline and that combined physical/mental challenges may be more effective than either alone but up to this point there has been little quality clinical evidence. Building on previous successful studies with our established tai ji quan therapy, we developed a cognitively-enhanced training tai ji quan protocol to determine its effectiveness in enhancing global cognition and dual-task walking compared to our standard tai ji quan program and a stretching program in adults 65+ with mild cognitive impairment or self-reported memory concerns.

Alzheimer's - Dementia, Author Interviews, Baylor College of Medicine Houston / 22.10.2023

MedicalResearch.com Interview with: David B. Corry, M.D. Professor of Pathology & Immunology and Medicine Vice Chair for Immunology Department of Pathology & Immunology Biology of Inflammation Center Dan L. Duncan Comprehensive Cancer Center   Clarence and Irene H. Fulbright Chair in Pathology Baylor College of Medicine Michael E. Debakey VA Medical Center MedicalResearch.com: What is the background for this study? Can candida species cross the blood brain barrier? Response: We showed earlier (2019) that the common fungus Candida albicans can enter the brain from the blood. That earlier study was in turn inspired by the finding of another research group that had found Candida in the brains of persons suffering from Alzheimer’s Disease and related dementing illnesses.

PTSD / 06.10.2023

Even when you have had the best military training available it is almost impossible to prepare your mind and body for the violence and traumatic experiences you might endure during active service. The threat of PTSD and other health issues is very real, such as veterans experiencing shell shock and still trying to process that experience many years later. Here is a look at some of the main health issues that a veteran might experience. Mental health challenges ptsd-veterans-warWearing the physical scars of war is just one side of the story. Many veterans can suffer significant mental health challenges long after they retire from active duty. The very real threat of Post Traumatic Stress Disorder (PTSD) has been well publicized in recent years. It is estimated that PTSD affects as many as 15% of veterans who fought in the Iraq war, for instance. Depression and alcohol abuse are other mental health issues faced by a percentage of veterans.

Accidents & Violence, ADHD, Author Interviews, Columbia, JAMA / 04.10.2023

MedicalResearch.com Interview with: Guohua Li, MD, DrPH Finster Professor of Epidemiology and Anesthesiology Columbia University Irving Medical Center MedicalResearch.com: What is the background for this study? How was the ADHD diagnosis determined? Response: The reported prevalence of ADHD in children and young adults in the United States has more than doubled since the 1990s because of improved diagnosis.  Currently, ADHD affects about 13 percent of children under 18 years of age and eight percent of adults under 45 years of age.  Little is known about the prevalence of ADHD in older adults although it is estimated that ADHD symptoms may persist throughout the lifespan in about one-third of children diagnosed with the disorder.  Diagnostic criteria for adulthood ADHD include having five or more relevant symptoms, adverse impact on social, academic, and occupational activities,  and onset of symptoms before age 12. In this study, ADHD status is determined based on an affirmative response to the question of whether the participant had ever had ADHD or had ever been told by a doctor or other health professional that he or she had ADHD.

Accidents & Violence, Schizophrenia / 25.09.2023

Individuals suffering from mental health problems such as schizophrenia may utilize substances to deal with or cope with the issues they are experiencing. However, the abuse of substances can have a double effect on a person as it could complicate schizophrenia’s symptoms and potentially increase the likelihood of an individual experiencing or worsening symptoms. If your loved one is struggling with substance abuse and you fear this could cause or worsen mental health problems, you may consider taking them to a residential treatment near you to get professional assistance. Connection between Schizophrenia and Substance Abuse

addiction-schizophreniaOne of the most startling aspects of the connection between schizophrenia and substance abuse is the high prevalence of substance use disorders among those with schizophrenia. Studies consistently show that individuals diagnosed with schizophrenia are more likely to engage in substance abuse compared to the general population. This connection can be best demonstrated using the self-medication hypothesis.  According to this hypothesis, individuals with schizophrenia may turn to substances as a way to self-medicate or alleviate their distressing symptoms. Imagine dealing with hallucinations or disorganized thoughts—some may use alcohol or drugs to temporarily escape from this internal turmoil.

It is imperative to note that drug abuse does not in any way lead to schizophrenia. However, the misuse of drugs can be a catalyst if an individual is predisposed to the condition or if they are already experiencing mild symptoms. (more…)
Mental Health Research / 19.09.2023

 Individual psychotherapy provides a multitude of benefits to patients seeking treatment to help improve their mental health. Through talk therapy sessions, patients can become self-aware of feelings that may hinder their wellbeing in order to learn out to better cope with those feelings. What Is Individual Psychotherapy? Individual psychotherapy is a type of therapy in which the patient works one-on-one with a therapist to overcome feelings hindering their wellbeing. Individual psychotherapy helps patients talk through difficult situations and feelings to help them acknowledge and overcome something hurting their mental health. Individual psychotherapy helps treat a multitude of emotional and behavioral issues including:
  • Anxiety
  • Stress
  • Eating disorders
  • Substance use disorder
  • Addiction
Patients should only receive individual psychotherapy from a state-licensed psychologist, psychiatrist, psychiatric nurse practitioner, clinical social worker, or marriage and family therapist. These therapy sessions are confidential to help improve a patient’s overall mental health. (more…)
Addiction, Author Interviews, Cognitive Issues, Education, Karolinski Institute / 15.09.2023

MedicalResearch.com Interview with: Lotfi Khemiri Centre for Psychiatry Research Stockholm, SwedenLotfi Khemiri Centre for Psychiatry Research Stockholm, Sweden MedicalResearch.com: What is the background for this study? Response: Our study used large-scale national register data in close to 2 million children, and found that parental abuse of both alcohol and drugs are associated with increased risk of intellectual disability in the offspring. Importantly, the risk increase was observed in both mothers and fathers which to the best of our knowledge is a novel finding, and may be explained by both genetic and environmental factors including toxic effects of substance intake on fetal development.

Author Interviews, Depression, Endocrinology, Nature / 27.08.2023

MedicalResearch.com Interview with: Huizhong Whit Tao, PhD Professor of Physiology & Neuroscience Zilkha Neurogenetic Institute Department of Physiology & Neurosience Keck School of Medicine University of Southern California   MedicalResearch.com: What is the background for this study? Response: Previously, we published a study in which we found that a group of neurons, namely glutamatergic neurons, in the medial preoptic area (MPOA) of the hypothalamus mediate stress-induced anxiety states. This result inspired us to explore whether the MPOA can play a more general role in mood regulation. Fluctuations in the productive hormones secreted by women’s ovaries are known to cause mood swings. In some cases, rapid changes in the secretion of ovarian hormones can cause depressive-like symptoms. Key examples are postpartum and peri-menopausal depression. In this study, we intended to test whether the MPOA can also play a part in depressive states that are linked to fluctuations in ovarian hormones. (more…)
Author Interviews, Cognitive Issues, Memory / 07.08.2023

MedicalResearch.com Interview with: Michael Leon, Professor emeritusDepartment of Neurobiology and BehaviorCenter for the Neurobiology of Learning and MemoryInstitute for Memory Impairments and Neurological DisordersUniversity of California Irvine MedicalResearch.com: What is the background for this study?  What types of aromas were employed? Response: The olfactory system is the only sense to have a direct “superhighway” access to the memory centers of the brain. The other senses can contribute to the health of the memory centers, but they have to take the brain's “side streets” to get there and consequently have much less impact on the health of those centers. If there is olfactory loss for any reason, the memory centers start to deteriorate. Stimulation of those memory centers with odors allows those centers to allow for better memory. We used naturally occurring pleasant odors: rose, orange, eucalyptus, lemon, peppermint, rosemary, and lavender. (more…)
Author Interviews, Mental Health Research, Microbiome, Nature, OBGYNE, UCLA / 25.07.2023

MedicalResearch.com Interview with: Bridget Callaghan Ph.D. Assistant Professor of Psychology UCLA Dr. Callahan studies interactions between mental and physical health across development.   MedicalResearch.com: What is the background for this study? Response: A growing body of evidence links the gut microbiome to brain and immune functioning, and changes to that community of microorganisms is likely among the ways that hardship affects children’s socioemotional development. Limited evidence in humans has demonstrated the adversities experienced prenatally and during early life influence the composition of the gut microbiome, but no studies had examined whether stress experienced in a mother's own childhood could influence the microbiome of the next generation of children.

Addiction, Author Interviews, Cannabis, Mental Health Research / 12.07.2023

MedicalResearch.com Interview with: Jessica Kruger PhD Clinical Associate Professor of Community Health and Health Behavior University at Buffalo School of Public Health and Health Professions MedicalResearch.com: What is the background for this study? Response: The 2018 Farm Bill authorizing hemp production led to new cannabinoids in the consumer marketplace. As the market becomes increasingly saturated with suppliers, companies continually diversify available products. The rapid emergence of novel cannabinoids outpaces systematic research necessary to inform regulations and harm reduction. Empirical evidence is needed to guide policies, practices, and education of consumers. Product manufacturers, social media participants, and cannabis oriented on-line news sources have claimed that THC-O-acetate is a "psychedelic" cannabinoid, producing experiences similar to those associated with LSD, psilocybin, mescaline, and DMT.

Aging, Author Interviews, Mental Health Research, Sleep Disorders / 02.07.2023

MedicalResearch.com Interview with: Valentina Paz, M.Sc Ph.D.  Student Research and teaching assistant Universidad de la República, UruguayHon. Research AssistantMRC Unit for Lifelong Health & Ageing Department of Population Science & Experimental MedicineInstitute of Cardiovascular ScienceUniversity College London MedicalResearch.com: What is the background for this study? Response: Prior research indicates that napping can enhance performance on specific cognitive tasks. However, some authors argue that the advantages derived from napping may vary between individuals who frequently have a nap and those who never naps. Furthermore, it remains to be seen whether habitual daytime napping has a positive or negative impact on cognition and the association between napping and brain volume is not well characterized. Therefore, our study aimed to examine whether the association between genetic liability to daytime napping, cognitive function, and brain volumes might be causal using a technic called Mendelian randomization and the UK Biobank.

Author Interviews, Depression, JAMA, Mental Health Research, NYU, USPSTF / 27.06.2023

MedicalResearch.com Interview with: Gbenga Ogedegbe, MD, MPH Dr. Adolph & Margaret Berger Professor of Population Health Director, Division of Health & Behavior Director Center for Healthful Behavior Change Department of Population Health NYU Langone Health NYU School of Medicine Member of the U.S. Preventive Services Task Force   MedicalResearch.com: What is the background for this study? Response: Depression and anxiety disorders are common mental health conditions affecting the lives of many adults in the U.S. The Task Force cares deeply about the health of people nationwide, so we reviewed the latest evidence on how best to support the mental health of adults in primary care. MedicalResearch.com: What are the main findings? Response:  The evidence shows us that all adults should be screened for depression and those under 65 should also be screened for anxiety. These recommendations apply to everyone without signs or symptoms of depression or anxiety. We also strongly encourage anyone who has signs of depression or anxiety to talk with their clinician so that they can get the care they need. (more…)
Alzheimer's - Dementia, Author Interviews, Genetic Research / 14.06.2023

MedicalResearch.com Interview with: Alexandra M Whiteley PhD Department of Biochemistry University of Colorado Boulder Boulder, Colorado MedicalResearch.com: What is the background for this study? Response: My laboratory was interested in understanding how UBQLN2 maintains cellular health. Ubiquilins facilitate protein degradation, but the precise proteins that they help to break down were not well understood. UBQLN2 is of particular interest because mutations in the UBQLN2 gene lead to a familial form of ALS. This project, which was published in eLife this year, stems from work that was published when I was a postdoctoral researcher at Harvard Medical School, where we found a link between UBQLN2 and the virus-like protein PEG10. Now at the University of Colorado, Boulder, my laboratory has focused on trying to understand this connection between the two proteins, and how PEG10 could contribute to ALS. (more…)
Alzheimer's - Dementia, Author Interviews, Biomarkers, University of Pittsburgh / 31.05.2023

MedicalResearch.com Interview with: Bruna Bellaver PhD Postdoctoral associate Department of Psychiatry University of Pittsburgh Tharick Pascoal, MD, Ph.D. Neurologist and assistant professor of Neurology and Psychiatry University of Pittsburgh School of Medicine. MedicalResearch.com: What is the background for this study? Response: Amyloid-β (Aβ) deposition is considered one of the markers of Alzheimer’s disease pathology in the brain. The sequential order of this cascade includes the development of tau pathology and consequent cognitive decline. However, many people with Aβ deposition in the brain do not progress in the disease, suggesting that other biological processes are playing a role in these pathological events. In vitro evidence suggests that reactive astrocytes unleash Aβ effects in pathological tau phosphorylation. We found that, in cognitively healthy individuals, Aβ is associated with tau pathology only in individuals with increased astrocyte reactivity. (more…)
Author Interviews, Lifestyle & Health, Mental Health Research, Sleep Disorders / 30.05.2023

MedicalResearch.com Interview with: Joanna Gorgol PhD Student University of Warsaw MedicalResearch.com: What is the background for this study? Response: People differ in the time when they prefer to wake up and fall asleep: some people prefer going to bed and waking up early, while others prefer later hours. Most of the population is somewhere between them. Research indicates that being a morning person is related to reporting higher satisfaction with life and conscientiousness. Studies also show the associations between being religious and having higher life satisfaction and conscientiousness. It seems that religiosity might mediate the relationship between morningness and higher life satisfaction. To better understand these associations we conducted two questionnaire-based studies of Polish adults, one with 500 participants and the other with 728 participants. All participants completed questionnaires measuring their chronotype, satisfaction with life, personality traits, and religiosity (more…)
Alzheimer's - Dementia, Author Interviews, Lifestyle & Health, Nutrition, Vegetarians / 30.05.2023

MedicalResearch.com Interview with: JoAnn E. Manson, MD, DrPH, MACP Chief, Division of Preventive Medicine Brigham and Women's Hospital Professor of Medicine and the Michael and Lee Bell Professor of Women's Health Harvard Medical School Boston, Massachusetts  02215   MedicalResearch.com: What is the background for this study?  Any particular types of vitamins, ie with/without iron etc? Response: Preserving memory and cognitive health is a high priority for most mid-life and older adults.  However, few strategies have been rigorously tested in randomized clinical trials and shown to have cognitive benefits. Nutritional approaches hold promise because the brain requires several nutrients for optimal health, and deficiencies in one or more of these nutrients may lead to accelerated memory loss and cognitive decline. The COcoa Supplement and Multivitamin Outcomes Study (COSMOS), a large-scale nation-wide randomized trial of multivitamins and cocoa flavanols had recently reported that multivitamins slowed global cognitive decline and memory loss (in COSMOS-Mind). The current study was a 2nd parallel trial, a collaboration between Brigham and Women’s Hospital and Columbia University, looking at a web-based assessment of the role of a  standard multivitamin and of cocoa flavanols in slowing age-related memory loss. The report in AJCN is on the multivitamin-cognition findings. The multivitamin tested was Centrum silver for adults (without iron). (more…)
Alzheimer's - Dementia, Author Interviews, Biomarkers, JAMA, MRI / 22.05.2023

MedicalResearch.com Interview with: Ruben Smith MD, PhD Associate professor at Clinical Memory Research Division of Neurology Lund University   MedicalResearch.com: What is the background for this study? Response: Since a few years it has become possible to visualize tau pathology in Alzheimer’s Disease (AD) using positron emission tomography (PET). The tau-PET radiotracer Flortaucipir (Tauvid) was recently approved by the US Food and Drug Administration as an AD diagnostic tool. Since PET imaging is costly and exposes the patient to radioactivity we wanted to study the added clinical value of tau-PET in the diagnostic work-up of patients with cognitive symptoms, before widespread implementation in clinical practice.

Alzheimer's - Dementia, Author Interviews, Cost of Health Care, JAMA, UCLA / 20.05.2023

MedicalResearch.com Interview with: Julia Cave Arbanas Project Manager and     John N. Mafi, MD, MPH Associate Professor of Medicine General Internal Medicine & Health Services Research David Geffen School of Medicine at UCLAJohn N. Mafi, MD, MPH Associate Professor of Medicine General Internal Medicine & Health Services Research David Geffen School of Medicine at UCLA   MedicalResearch.com: What is the background for this study? What is lecanemab used for and how well does it work? Response: Lecanemab is a treatment for mild cognitive impairment and mild dementia that was approved in January 2023 as part of the Food and Drug Administration’s (FDA) accelerated approval program. The results from a recent phase 3 clinical trial show a modest clinical benefit: the rate of cognitive decline by 27% in an 18-month study involving participants experiencing the early stage of Alzheimer’s, with an 0.45-point absolute difference in cognitive testing scores. However, due to the risk of brain swelling and bleeding (also known as amyloid-related imaging abnormalities), treatment with lecanemab involves frequent MRIs and neurology or geriatrics appointments to monitor for these abnormalities, which can be life threatening. So far, three patient deaths have potentially been tied to lecanemab. It is likely that the FDA will grant is lecanemab traditional approval later this year, prompting Medicare to reconsider its current coverage restrictions and potentially enabling widespread use.

Alzheimer's - Dementia, Author Interviews, JAMA, Mediterranean Diet, Mental Health Research / 08.05.2023

MedicalResearch.com Interview with: Yuan Changzheng ScD, MSc, B.M. Research Professor Doctoral supervisor, School of Medicine Zhejiang University School of Public Health Adjunct assistant professor Harvard T.H. Chan School of Public Health   MedicalResearch.com: What is the background for this study? Response: The prevention of all-cause dementia is important as it poses substantial burdens on healthcare systems and threatens the well-being of older adults, and lack of effective treatments makes its prevention crucial. The Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet is a hybrid of the Mediterranean diet and the DASH diet, and it emphasizes natural plant-based foods, limited intake of certain animal foods and foods high in saturated fat and encourages consumption of berries and green leafy vegetables rich in vitamins and antioxidants. The MIND diet has previously been associated with lower risk of Alzheimer's disease and slower cognitive decline but few studies have examined its association with all-cause dementia or AD with inconclusive results.

This article is for informational purposes only and is not a substitute for professional medical advice, diagnosis or treatment. Contact a qualified medical professional before engaging in any physical activity, or making any changes to your diet, medication or lifestyle, Panic disorder is a mental health condition that affects millions of people all over the world. It is characterized by intense bouts of fear and anxiety, often accompanied by physical symptoms such as increased heart rate, sweating, and difficulty breathing. People with panic disorder can be overwhelmed by feelings of terror and helplessness. This can significantly impact their daily lives and make it difficult to live life to the fullest. Let’s take a closer look at what panic disorder is and how it can be managed.

What Causes Panic Disorder?

The exact cause of the panic disorder is not known, but there are many factors that may contribute to its onset. These factors include genetics, family history, traumatic events, major life transitions or changes, stressors such as work or school pressures, and certain medical conditions or medications. It is important to note that experiencing one or more of these contributing factors does not necessarily mean that someone will develop panic disorder - rather, they may increase the likelihood of developing the condition.

ADHD, Author Interviews, JAMA, Pediatrics, University of Michigan / 18.04.2023

MedicalResearch.com Interview with: Sean Esteban McCabe, PhD Director, Center for the Study of Drugs, Alcohol, Smoking and Health Department of Health Behavior and Biological Sciences University of Michigan School of Nursing Ann Arbor, MI MedicalResearch.com: What is the background for this study? Response: Prescription stimulant therapy for ADHD helps millions of people, including in my own family, and students, friends and colleagues. It's critical to balance the need for access to these medications while reducing the risk for misuse. This is more important than ever now because there have been recent increases in the prescribing of stimulant therapy for ADHD. There is a need to understand the prevalence of stimulant therapy for ADHD and prescription stimulant misuse in U.S. middle and high schools. (more…)
