Polyphenol Diet And Exercise As Neuroprotection From Effects Of Alzheimer's Disease, Michelle Morgan Aug 2026

Polyphenol Diet And Exercise As Neuroprotection From Effects Of Alzheimer's Disease, Michelle Morgan

Loma Linda University Electronic Theses, Dissertations & Projects

Healthy non-pharmacological lifestyle factors, such as regular physical exercise and a dietary supplementation, have been shown to significantly improve cognitive outcomes over time compared to a more sedentary lifestyle and poor diet. Furthermore, exercise may serve as a potential protective factor in attenuating the effects associated with cognitive decline that are characteristic of neurodegenerative disorders, such as Alzheimer's disease (AD). Further, evidence indicates that certain diet interventions can also attenuate the effects of neurodegeneration and positively impact longevity. Supplementation of polyphenols, such as ellagic acid (EA), which are abundant in pomegranate juice, may help provide neuroprotective benefits and elicit a …


The Relationship Between Depression And Cognitive Proficiency Index Across Biological Sex, Angela N. Ferdinardo Aug 2026

The Relationship Between Depression And Cognitive Proficiency Index Across Biological Sex, Angela N. Ferdinardo

Dissertations

Depression is a widely studied mood disorder, and understanding its effect on cognitive functioning has become an important area of research. While research has examined relationships among depression, working memory, and cognitive deficits, limited research has explored depressive symptoms and cognitive proficiency across biological sex. Depression manifests similarly in men and women, though men are more likely to experience irritability, impulsivity, and anger, while women tend to experience sadness, stress, and sleep disturbances (Johns Hopkins Medicine, 2023). Women are also more likely to seek treatment and cope differently than men. This study examined the relationship between depression and cognitive proficiency …


Determinants Of Corporal Punishment And Severe Physical Punishment In Egypt: A Mixed-Methods Analysis For Child Protection Policy, Marwa Moustafa Nassef Jun 2026

Determinants Of Corporal Punishment And Severe Physical Punishment In Egypt: A Mixed-Methods Analysis For Child Protection Policy, Marwa Moustafa Nassef

Theses and Dissertations

Corporal punishment (CP) and severe physical punishment (SPP) remain a major public health, child rights, and child protection policy concern. In Egypt, despite legislative reforms, survey-weighted analysis of the 2021 Egypt Family Health Survey (EFHS) 2021 (CAPMAS, 2022) reveals prevalence rates of 60.5% for CP and 27.4% for SPP among children aged 1–14 (author’s calculations using EFHS-2021, n=7623), yet evidence distinguishing the determinants of routine corporal punishment from escalation to severe physical punishment remains limited in low- and middle-income contexts. Guided by Bronfenbrenner’s ecological framework, this mixed-methods study identifies key drivers of CP and its escalation to SPP among Egyptian …


A Predictive Coding Account Of Spatial Working Memory Following Prophylactic Levetiracetam Administration Prior To Traumatic Brain Injury, Omeima Mutwali Jun 2026

A Predictive Coding Account Of Spatial Working Memory Following Prophylactic Levetiracetam Administration Prior To Traumatic Brain Injury, Omeima Mutwali

Dissertations, Theses, and Capstone Projects

Traumatic brain injury (TBI) symptom prevention and remediation is an important area of research that would benefit vulnerable groups, including active-duty and veteran soldiers. These patients can sustain penetrative forces in fields of combat or in training, which result in focal lesions that trigger inflammatory and degenerative processes in the brain. Both primary and secondary injuries are associated with changes to cognition, behavior and affective state. This disease poses increased risk of epileptogenesis, as well. Given these outcomes, prior research has evaluated levetiracetam (LEV) as a prophylactic treatment for seizures, cognitive deficits and negative emotionality. LEV acts as a presynaptic …


I Lost My Number, Can I Have Yours? Body Image Satisfaction With Sexually Dimorphic Traits Is Associated With Men's Dating Anxiety And Confidence, David A. Frederick, Tania A. Reynolds, Nikoline L. Smart, Justin R. Garcia, David A. Puts May 2026

I Lost My Number, Can I Have Yours? Body Image Satisfaction With Sexually Dimorphic Traits Is Associated With Men's Dating Anxiety And Confidence, David A. Frederick, Tania A. Reynolds, Nikoline L. Smart, Justin R. Garcia, David A. Puts

Psychology Faculty Articles and Research

Evolutionary scientists posit that sexual selection processes caused males to develop sexually dimorphic traits to aid them during intrasexual competition and increase their likelihood of being chosen as mates. Evolutionary social sciences have extensively examined women's preferences for traits such as muscle mass and voice pitch, reasoning that these traits serve as cues of men's ability to provide direct benefits (e.g., resources) and indirect (genetic) benefits passed on to offspring. At the same time, body image researchers have extensively focused on the social causes and consequences of men's dissatisfaction with their muscularity and body fat. We connected these two research …

Dietary Flavonoid Intake And Psychological Well-Being – A Bidirectional Relationship, Alysha S. Thompson, Nicola P. Bondonno, Yan Lydia Liu, Farah Qureshi, Laura D. Kubzansky, Claudia Trudel-Fitzgerald, Julia K. Boehm, Eric B. Rimm, Aedín Cassidy

Psychology Faculty Articles and Research

Background and aim

Higher dietary flavonoid intake has been associated with lower risks of mortality and major chronic disease, yet its relationship with psychological well-being (PWB), a key contributor to health and quality of life, remains unclear. This study aimed to investigate bidirectional associations between dietary flavonoid intake and two PWB facets: happiness (positive emotional state) and optimism (generalized expectation of positive outcomes). Specifically, we examined whether (1) overall flavonoid-rich dietary patterns (flavodiet score), (2) intake of specific flavonoid-rich foods, and (3) total flavonoid and subclass intakes were each associated with happiness and optimism over time.

Methods

Data were drawn …


Psychological Impacts In Exercise Riders And Professional Jockeys Following Injury, Kelley M. Renner Jan 2025

Psychological Impacts In Exercise Riders And Professional Jockeys Following Injury, Kelley M. Renner

Theses and Dissertations--Kinesiology and Health Promotion

One of the most well-known equestrian sports, horse racing, is not only a cornerstone of Kentucky’s economy, but also a vital part of its culture, with professional jockeys playing an essential role in the local communities and traditions that define the state. Despite its popularity and financial impact, mental health challenges within the sport have continually been shrouded in silence and ignored in research (Ball et al., 2007). Equally concerning is the high injury prevalence, and psychological impact of these injuries (e.g., psychological distress, depression, anxiety, loss of identity, and self-esteem (King et al., 2022; Losty et al., 2019; McConn-Palfreyman …


Bridging The Gap: Psychopharmacologic Education And Side Effect Screening For Non-Prescribing Mental Health Professionals, Elaine Fitzgerald Jul 2024

Bridging The Gap: Psychopharmacologic Education And Side Effect Screening For Non-Prescribing Mental Health Professionals, Elaine Fitzgerald

Dissertations

Abstract

Problem: The United States is experiencing a growing demand for pediatric mental health support. Surges in mental health diagnoses and psychotropic medication prescriptions have occurred, compounded by a shortage of psychiatric providers. Non-prescribing mental health professionals are well-positioned to recognize psychotropic medication side effects. However, psychologists and counselors lack formal pharmacology education.

Methods: The quality improvement (QI) initiative was guided by the Plan-Do-Study-Act (PDSA) model. The evidence-based psychopharmacologic education for non-prescribers utilized a quasi-experimental pre- and post- test design. Data collected from clinicians included knowledge, confidence, and skill concerning psychotropic medications. The Psychotropic Medication Monitoring Checklist (PMMC) screen clients …

Using Machine Learning To Determine A Functional Classifier Of Reward Responsiveness And Its Association With Adolescent Psychiatric Symptomatology, Robert James Richard Blair, Johannah Bashford-Largo, Ahria Dominguez, Matthew Dobbertin, Karina S. Blair, Sahil Bajaj

Center for Brain, Biology, and Behavior: Faculty Publications

Background. Machine learning (ML) has developed classifiers differentiating patient groups despite concerns regarding diagnostic reliability. An alternative strategy, used here, is to develop a functional classifier (hyperplane) (e.g. distinguishing the neural responses to received reward v. received punishment in typically developing (TD) adolescents) and then determine the functional integrity of the response (reward response distance from the hyperplane) in adolescents with externalizing and internalizing conditions and its associations with symptom clusters.

Methods. Two hundred and ninety nine adolescents (mean age = 15.07 ± 2.30 years, 117 females) were divided into three groups: a training sample of TD adolescents …

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

When postmenopausal women are under stress conditions, this exacerbates mood disorders and issues with neuroimmune systems. The porcine placenta is known to relieve menopausal depression in clinical trials, but its underlying mechanisms for depression and anti-inflammatory functions remain poorly defined. The present study was designed to examine the anti-inflammatory effects of enzymatic porcine placenta hydrolysate (EPPH) on LPS-induced levels of nitric oxide (NO), prostaglandin E2 (PGE2), corticosterone (CORT), and pro-inflammatory cytokine interleukin-1 beta (IL-1β) in RAW 264.7 macrophage cells. In addition, the neurite outgrowth of PC12 cells was evaluated to examine the effects of EPPH on neurite growth. To mimic …


Less Activity Means Improved Welfare? How Pair Housing Influences Pinyon Jay (Gymnorhinus Cyanocephalus) Behaviour, London M. Wolff, Jeffrey R. Stevens Jun 2024

Less Activity Means Improved Welfare? How Pair Housing Influences Pinyon Jay (Gymnorhinus Cyanocephalus) Behaviour, London M. Wolff, Jeffrey R. Stevens

Center for Brain, Biology, and Behavior: Faculty Publications

The activity level and specific behaviours exhibited by captive animals are crucial indicators of welfare. Stereotypies, or repetitive behaviours that have no apparent function or goal, are performed by animals experiencing poor conditions in their environment and indicate welfare concerns. Changes in the housing environment in particular may have critical influences on behaviour and welfare. Here, we measured behavioural changes in a captive pinyon jay (Gymnorhinus cyanocephalus) population (n = 10) associated with a shift from single to pair housing. Using automated video processing, we show that pair housing greatly reduced overall activity levels in these birds. The …


The Alexander Technique Applied To Dance And The Choreographic Process: Freeing Physical Expression From Trauma-Based Tension, Julia Johnston Apr 2024

The Alexander Technique Applied To Dance And The Choreographic Process: Freeing Physical Expression From Trauma-Based Tension, Julia Johnston

Senior Honors Theses

Ballet, contemporary, and modern dancers have expressed incurring trauma during their training and professional dance experiences; in a 2020 survey, 41% of professional dancers and 30% of ballet students reported experiencing or witnessing sexually inappropriate behavior in their respective workplaces and schools (DDP). This is just one example of a potential source of trauma for dancers. The physiological effects of trauma cause physical effects, creating tension in a dancer’s body. Dance relies on physical expression, the expression of thought and feeling through movement, to connect with the audience. Trauma-based tension inhibits a dancer’s range of physical expression and connection to …


Impact Of Equine Interaction During Psychotherapy On Anxiety And Depression For Residential Treatment Program Patients Experiencing Substance Withdrawal, Molly M. Friend, Molly C. Nicodemus, Clay Cavinder, Caleb Lemley, Pauline Prince, Katherine A. Cagle-Holtcamp, Rebecca M. Swanson Feb 2024

Impact Of Equine Interaction During Psychotherapy On Anxiety And Depression For Residential Treatment Program Patients Experiencing Substance Withdrawal, Molly M. Friend, Molly C. Nicodemus, Clay Cavinder, Caleb Lemley, Pauline Prince, Katherine A. Cagle-Holtcamp, Rebecca M. Swanson

People and Animals: The International Journal of Research and Practice

As incidences of substance use disorders (SUD) increase in the wake of the COVID-19 pandemic, there is a need for more effective treatment approaches. Further, treatment approaches currently available struggle to retain patients during the period of substance withdrawal in early treatment due to patients’ withdrawal symptoms including increased feelings of anxiety and depression. Withdrawal symptoms have been linked to dysregulated cortisol concentrations present in this period. Psychotherapy incorporating equine interaction (PIE) has emerged in other populations as a treatment that decreases cortisol concentrations and improves treatment retention. The present study investigated the impact of 4 weeks of PIE on …


Associations Of Sex And Sport Contact‑Level With Recovery Timelines Among Collegiate Athletes With Sport‑Related Concussion, Bernadette A. D'Alonzo, Andrea L. C. Schneider, Ian J.

Barnett, Christina L. Master, Abigail C. Bretzin, Douglas J. Wiebe, Ivy League-Big Ten Epidemiology Of Concussion Study Investigators

Center for Brain, Biology, and Behavior: Faculty Publications

Background

Growing interest has motivated recent studies to examine differences in recovery after sportrelated concussion (SRC) by sex. However, heterogeneity in study design, participants, and recovery outcomes has led to mixed findings. Further work is needed to evaluate potential differences by sex and to investigate the role of related characteristics, such as sport contact-level, in recovery timelines. This study aimed to investigate whether concussion recovery trajectories differ by sex, considering a priori clinical and demographic covariates, and accounting for the sequence of recovery outcomes. Our secondary question was whether sport contact-level modifies the relationship between sex and time to outcomes. …


Identifying Youth Appeals In Alcohol Alternative Social Media Content Through Framing, Melina Oneal Jan 2024

Identifying Youth Appeals In Alcohol Alternative Social Media Content Through Framing, Melina Oneal

West Chester University Master’s Theses

Proposed regulations for alcohol advertising prevent beverage companies from targeting people under the legal drinking age. However, similar regulations for alcohol alternative beverages are less explored, which could allow alcohol alternative products to create awareness for alcoholic beverages among youth. Alcohol alternatives beverages, including no-alcohol and low-alcohol products, are increasing in popularity and can function as compliments to alcoholic products to decrease the total alcohol volume consumed or as substitutes for alcoholic products. Framing theory can be operationalized through the Content Appealing to Youth Index, an index of content elements found in research literature to be appealing to youth, to …


Detecting Cognitive Decline In High-Functioning Older Adults: The Relationship Between Subjective Cognitive Concerns, Frequency Of High Neuropsychological Test Scores, And The Frontoparietal Control Network, Justin E. Karr, Jonathan G. Hakun, Daniel B. Elbich, Cristina N. Pinheiro, Frederick A. Schmitt Jan 2024

Detecting Cognitive Decline In High-Functioning Older Adults: The Relationship Between Subjective Cognitive Concerns, Frequency Of High Neuropsychological Test Scores, And The Frontoparietal Control Network, Justin E. Karr, Jonathan G. Hakun, Daniel B. Elbich, Cristina N. Pinheiro, Frederick A. Schmitt

Neurology Faculty Publications

Objective: Neuropsychologists have difficulty detecting cognitive decline in high-functioning older adults because greater neurological change must occur before cognitive performances are low enough to indicate decline or impairment. For high-functioning older adults, early neurological changes may correspond with subjective cognitive concerns and an absence of high scores. This study compared high- functioning older adults with and without subjective cognitive concerns, hypothesizing those with cognitive concerns would have fewer high scores on neuropsychological testing and lower frontoparietal network volume, thickness, and connectivity.

Method: Participants had high estimated premorbid functioning (e.g., estimated intelligence ≥75th percentile or college-educated) and were divided based on …

Center for Brain, Biology, and Behavior: Faculty Publications

Background Latina mothers have been especially affected by the pandemic and historically exhibit high rates of depression and anxiety. However, few longitudinal studies have assessed the effect of the pandemic on this vulnerable population. We hypothesized that COVID-19-related stressors would associate with psychological distress among Latina mothers across the first year of the pandemic.

Methods We investigated COVID-19-related impact, stigma, and fears across two critical time points and changes in these measures in relation to changes in maternal anxiety and depression among mothers of Mexican descent living in Southern California (n=152). Surveys were administered within 5–16 weeks of …

Blair, Matthew Dobbertin, Jaimie Elowsky, Johannah Bashford‑Largo, Ahria J. Dominguez, Melissa Hatch, Sahil Bajaj

Center for Brain, Biology, and Behavior: Faculty Publications

Background

Conduct disorder (CD) involves a group of behavioral and emotional problems that usually begins during childhood or adolescence. Structural brain alterations have been observed in CD, including the amygdala, insula, ventrolateral and medial prefrontal cortex, anterior cingulate cortex, and fusiform gyrus. The current study developed a multivariate generalized linear model (GLM) to differentiate adolescents with CD from typically developing (TD) adolescents in terms of grey matter volume (GMV).

Methods

The whole‐brain structural MRI data were collected from 96 adolescents with CD (mean age = 16.188 ± 1.259 years; mean IQ = 104.292 ± 8.107 ; 63 males) and 90 …


Specialized Late Cingulo-Opercular Network Activation Elucidates The Mechanisms Underlying Decisions About Ambiguity, Jordan E. Pierce, Nathan M. Petro, Elizabeth Clancy, Caterina Gratton, Steven E. Petersen, Maital Neta Oct 2023

Specialized Late Cingulo-Opercular Network Activation Elucidates The Mechanisms Underlying Decisions About Ambiguity, Jordan E. Pierce, Nathan M. Petro, Elizabeth Clancy, Caterina Gratton, Steven E. Petersen, Maital Neta

Center for Brain, Biology, and Behavior: Faculty Publications

Cortical task control networks, including the cingulo-opercular (CO) network play a key role in decision-making across a variety of functional domains. In particular, the CO network functions in a performance reporting capacity that supports successful task performance, especially in response to errors and ambiguity. In two studies testing the contribution of the CO network to ambiguity processing, we presented a valence bias task in which masked clearly and ambiguously valenced emotional expressions were slowly revealed over several seconds. This slow reveal task design provides a window into the decision-making mechanisms as they unfold over the course of a trial. In …

Assessing Blood Oxygen Level–Dependent Signal Variability As A Biomarker Of Brain Injury In Sport-Related Concussion, Evan D. Anderson, Tanveer Talukdar, Grace Goodwin, Valentina Di Pietro, Kamal M. Yakoub, Christopher E. Zwilling, David Davies, Antonio Belli, Aron K. Barbey

Center for Brain, Biology, and Behavior: Faculty Publications

Mild traumatic brain injury is a complex neurological disorder of significant concern among athletes who play contact sports. Athletes who sustain sport-related concussion typically undergo physical examination and neurocognitive evaluation to determine injury severity and return-to-play status. However, traumatic disruption to neurometabolic processes can occur with minimal detectable anatomic pathology or neurocognitive alteration, increasing the risk that athletes may be cleared for return-to-play during a vulnerable period and receive a repetitive injury. This underscores the need for sensitive functional neuroimaging methods to detect altered cerebral physiology in concussed athletes. The present study compared the efficacy of Immediate Post-concussion Assessment and …

Identification Of Structural Brain Alterations In Adolescents With Depressive Symptomatology, J. Bashford‑Largo, R. James R. Blair, Karina S. Blair, Matthew Dobbertin, Ahria Dominguez, Melissa Hatch, Sahil Bajaj

Center for Brain, Biology, and Behavior: Faculty Publications

Introduction: Depressive symptoms can emerge as early as childhood and may lead to adverse situations in adulthood. Studies have examined structural brain alternations in individuals with depressive symptoms, but findings remain inconclusive. Furthermore, previous studies have focused on adults or used a categorical approach to assess depression. The current study looks to identify grey matter volumes (GMV) that predict depressive symptomatology across a clinically concerning sample of adolescents.

Methods: Structural MRI data were collected from 338 clinically concerning adolescents (mean age = 15.30 SD=2.07; mean IQ = 101.01 SD=12.43; 132 F). Depression symptoms were indexed via the Mood …

Effects Of Daylight On College Students’ Physical And Mental Well-Being, Sathya Thenappan Jun 2023

Effects Of Daylight On College Students’ Physical And Mental Well-Being, Sathya Thenappan

Quantitative Social Science Undergraduate Senior Theses

While existing literature predominantly deals with the impact of daylight on adults in general and more specifically at the workplace, less is known about its impact on the college student demographic and daylight exposure levels at college residences. Given its considerable impact on both the physical and mental well-being of individuals, daylight has been used in the treatment of an assortment of diseases from seasonal affective disorder to depression. With college students constituting the majority of today’s people who suffer from mental health issues in society, uncovering the link between daylight exposure and its impact on the physical and mental …


Therapeutic Approaches To Working With Perinatal Loss Clients: A Grounded Theory Study, Heather H. Olivier May 2023

Therapeutic Approaches To Working With Perinatal Loss Clients: A Grounded Theory Study, Heather H. Olivier

University of New Orleans Theses and Dissertations

Perinatal loss (i.e., miscarriage, stillbirth, termination, and infant death) is commonly referred to in the literature as an invisible loss, non-loss, and even medical event. It is an ambiguous loss exhibiting the dialectical contradiction between the physical absence and psychological presence of the baby accompanied by disenfranchised grief, a reaction to a loss that is unacknowledged by society. Despite the likelihood of mental health clinicians working with clients who have experienced perinatal loss, there has yet to be a therapeutic model designed specifically for the unique grief and trauma reactions presented in this population. Existing grief models do not address …


Role Of Nucleus Accumbens Dopamine Receptor Signaling In The Suppression Of Punished Reward Seeking, Grace M. Joyner, Anna Caroline Toburen Apr 2023

Role Of Nucleus Accumbens Dopamine Receptor Signaling In The Suppression Of Punished Reward Seeking, Grace M. Joyner, Anna Caroline Toburen

Senior Theses

Previous studies have shown that within the nucleus accumbens (NAc), a brain region associated with motivation and reinforcement learning, activity of neurons expressing the dopamine D2 receptor (D2R neurons) act as a “break” on risky behavior associated with negative outcomes. Moreover, when these neurons are stimulated, rats were found to become more risk averse. However, the impact of dopamine signaling through NAc D2R neurons in risk avoidance is still unclear. To further explore the role of NAc dopamine signaling in punished reward-seeking, we tested rats in a novel punished food-seeking paradigm in which subjects are trained to choose between a …


Cervical Spinal Cord Injury Leads To Injury And Altered Metabolism In The Lungs, Emily E. Huffman, Brittany E. Dong, Harrison A. Clarke, Lyndsay E. A. Young, Matthew S. Gentry, Derek B. Allison, Ramon C. Sun, Christopher M. Waters, Warren J. Alilain Mar 2023

Cervical Spinal Cord Injury Leads To Injury And Altered Metabolism In The Lungs, Emily E. Huffman, Brittany E. Dong, Harrison A. Clarke, Lyndsay E. A. Young, Matthew S. Gentry, Derek B. Allison, Ramon C. Sun, Christopher M. Waters, Warren J. Alilain

Saha Cardiovascular Research Center Faculty Publications

High-cervical spinal cord injury often disrupts respiratory motor pathways and disables breathing in the affected population. Moreover, cervically injured individuals are at risk for developing acute lung injury, which predicts substantial mortality rates. While the correlation between acute lung injury and spinal cord injury has been found in the clinical setting, the field lacks an animal model to interrogate the fundamental biology of this relationship. To begin to address this gap in knowledge, we performed an experimental cervical spinal cord injury (N = 18) alongside sham injury (N = 3) and naïve animals (N = 15) to assess lung injury …


Higher Sexual Excitation Is Associated With An Increase In Sex-Linked Substance Use In Women With A History Of Unwanted Sexual Contact, Harper R. Jones, Tierney K. Lorenz Jan 2023

Higher Sexual Excitation Is Associated With An Increase In Sex-Linked Substance Use In Women With A History Of Unwanted Sexual Contact, Harper R. Jones, Tierney K. Lorenz

Center for Brain, Biology, and Behavior: Faculty Publications

Survivors of unwanted sexual contact have an increased likelihood of using substances in sexual situations, which puts them at heightened risk for intoxication-related harms. Separately, research has indicated that women may intentionally use substances in sexual situations to either enhance pleasure (i.e., increase sexual excitation) and/or reduce sexual anxiety or shame (i.e., reduce sexual inhibition), a phenomenon termed sex-linked substance use (SLSU). A predominant assumption in the literature is that women with unwanted sex histories are more likely to disengage during sex, suggesting greater inhibition-related SLSU; however, there is little prior research directly examining if women who have unwanted sex …
