Seizure-Induced Resolution Of Depressive And Psychotic Symptoms In A Pregnant Patient: A Case Of Spontaneous Neuromodulation, Ariel E. Sosa Gomez, Ryan M. Go, David Valdez

School of Medicine Publications

Many individuals with epilepsy often develop major depressive disorder (MDD), creating a complex interplay that exacerbates outcomes for affected individuals. The relationship between these disorders may be mediated by overlapping neurobiological mechanisms, including disturbances in the limbic system, neurotransmitter imbalances, and the psychosocial stressors of chronic illness. While the co-occurrence typically leads to a worsening of symptoms, rare instances have been reported in which seizure activity appears to ameliorate psychiatric symptomatology. We present the case of a 23-year-old pregnant Hispanic female with a longstanding history of treatment-resistant depression with psychotic features and epilepsy, who demonstrated full remission of depressive and …

Exploring Adolescent Hearing Aid Usage And Appearance Of Psychiatric Symptoms In Adolescents Using Hearql-28 Surveys, Courtney J. Austin, Dylan Chan

MEDI 9331 Scholarly Activities Clinical Years

Approximately 2% of DHH people in need of mental health services actually receive these services. Among pediatric hearing loss populations, co-occurring cognitive and physical impairments are risk factors for poor mental health status. Due to language barriers and isolation, more children with hearing loss do not have access to mental health services. Cochlear implants have been shown to improve mental health status among the DHH population. Current literature focuses on the mental health status of children with cochlear implants, with little focus on hearing aid users. Using HEAR28 data and surveys, we can quantify the incidence of psychiatric symptoms among …

Human Genetics Publications

Neuroanatomical findings on panic disorder (PD) are typically difficult to replicate, with inconsistent effects. These concerns prompted a paradigm shift towards large-scale collaborations, focused on harmonized data extraction and processing for robust examination of PD brain correlates. Hence, leveraging the largest-ever multi-site neuroimaging database on PD (Age: 10–66 years; global sites: 28), compiled by the ENIGMA-Anxiety Working Group, we report on cortical and subcortical differences in individuals with PD (N = 1146) versus healthy controls (HC: N = 3778). The analyses revealed lower thickness and smaller cortical surface area within fronto-temporo-parietal regions in PD (Cohen’s ds: −0.08–0.13), along with lower …

School of Medicine Publications

Genetic variants influencing gene expression have been extensively studied at the transcriptional level. How these variants affect downstream processes remains unclear. We quantitated ribosome occupancy in prefrontal cortex samples from the BrainGVEX cohort and integrated these data with transcriptomic and proteomic profiles from the same individuals. Through cis-QTL mapping, we identified genetic variants associated with transcript level (eQTLs), ribosome occupancy (rQTLs), and protein level (pQTLs). Notably, only 34% of eQTLs have their effects propagated to the protein levels, suggesting widespread post-transcriptional attenuation. Using both a gene-based approach and a variant-based approach we identified omics-specific QTLs that associated with brain disorder …

Measurement-Based Care For Depression In Youth: Practical Considerations For Selecting Measures To Assess Depression, Associated Features And Functioning, Cynthia Garza, Diana Chapa, Catherine Hernandez, Hayley Aramburu, Taryn L. Mayes, Graham J. Emslie

School of Medicine Publications

Identification and management of major depressive disorder (MDD) in children and adolescents remains a significant area of public health need. The process for identifying depression (e.g. screening) and management (e.g. measurement based care [MBC]) is substantially enhanced by utilization of clinical measures and rating scales. Measures can be self- or caregiver reported or clinician rated. They can aid recognition of at-risk individuals for future assessment and assist in clinical diagnosis and management of depression. In addition to assessing symptoms of depression, rating scales can be used to assess important associated features (e.g. anxiety, trauma) and functional outcomes (e.g. quality of …

Melgarejo, Gladys E. Maestre, Silvia Mejia-Arango

Research Colloquium

Background: The Uniform Data Set 3.0 Neuropsychological Battery (UDS3NB) is a standardized tool for assessing cognitive function in aging populations. Factor analytic studies on the UDS 3 have shown that performance across cognitive domains, such as memory, attention, executive function, language, and visuospatial abilities, can differentiate between cognitive status groups, cognitively normal (CN), mild cognitive impairment (MCI), and dementia. Understanding how specific cognitive domains relate to diagnostic categories, CN, MCI, and dementia, is essential for early identification. Additionally, socioeconomic and health factors may influence cognitive outcomes and should be considered alongside cognitive performance. The aims of this study are to: …

High-Resolution Mapping Of Alcohol-Related Brain Connectivity In Adults Using 7t Fmri And Multivoxel Pattern Classification, Alan N. Francis, Ihsan Salloum

School of Medicine Publications

Background: Emerging evidence suggests that alcohol use disrupts large-scale brain network interactions, particularly within the triple network model-comprising the Salience Network (SN), Default Mode Network (DMN), and Frontoparietal Network (FPN). However, few studies have examined how these connectivity alterations vary across the full spectrum of alcohol consumption, especially using ultra-high-field imaging and data-driven approaches. This study leverages 7 Tesla resting-state fMRI and multivariate pattern analysis (MVPA) to characterize distinct brain connectivity patterns across heavy, moderate, and non-drinking adults, aiming to identify neural signatures that differentiate alcohol use severity levels.

Methods: We analyzed resting-state functional connectivity data from 69 adults (Mean …

Impact Of Acute Stress On Circadian Rhythm Regulation Of Locomotor Activity In Syrian Hamsters, Raquel A. Villarreal, Laura E. Garcia, Mario Gil

Research Symposium

Background: Disruptions of circadian rhythms, caused by factors such as environmental changes or stress, are linked to health conditions, including metabolic disorders, cardiovascular diseases, and mood disorders. Circadian rhythm disturbances are particularly relevant for understanding the etiology of conditions like insomnia, depression, and anxiety. The circadian rhythm, primarily regulated by the suprachiasmatic nuclei (SCN) in the hypothalamus, coordinates biological processes to align with daily environmental cycles. Acute stress, especially when experienced immediately upon waking, has been shown to disrupt these rhythms, impair sleep regulation, and exacerbate mood dysregulation. Given the significant clinical implications, understanding how stress impacts circadian rhythms is …

Standardizing Resident Teaching In Psychiatry: A Guide For Student Engagement, Faiza Ahmad, Lesley Chapa Feb 2025

Standardizing Resident Teaching In Psychiatry: A Guide For Student Engagement, Faiza Ahmad, Lesley Chapa

MEDI 9331 Scholarly Activities Clinical Years

Residents play a crucial role in shaping medical students’ learning experiences and career decisions. However, interns enter residency with varying levels of teaching experience and may struggle to engage students while managing their clinical workload. This variability often leads to inconsistent educational experiences across rotations. In Psychiatry, students frequently find the Mental Status Examination (MSE) particularly challenging due to time constraints in clinical teaching, often resulting in a superficial understanding and rote documentation. As residents advance, their increasing clinical responsibilities and distance from Step 2/Shelf-relevant material can further limit their ability to provide effective teaching. This project aims to bridge …

School of Medicine Publications

Objective

Adolescents face significant changes in many domains of their daily lives that require them to flexibly adapt to changing environmental demands. To shift efficiently among various goals, adolescents must reconfigure their brains, disengaging from previous tasks and engaging in new activities.

Method

To examine this reconfiguration, we obtained resting-state and task-based fMRI scans in a community sample of 164 adolescents. We assessed the similarity of functional connectivity (FC) of the reward network between resting state and a reward processing state, indexing the degree of reward network reconfiguration required to meet task demands. Given research documenting relations among reward network …

The Role Of Oral Microbiota In Periodontitis And Alzheimer's Disease, Noah Al-Hassan, Taha Al Hassan, Juan C. Lopez-Alvarenga, Maria Quinones, Seratna Guadarrama

Research Symposium

Background: Periodontal disease (PD), affecting 20-50% of the global population is marked by biofilm-induced inflammation in oral tissues. Chronic PD results in systemic complications such as heart disease, stroke, and Alzheimer's. The red complex microbes, Porphyromonas gingivalis and Treponema denticola, play a pivotal role, penetrating the blood-brain barrier and contributing to neurodegeneration. Alzheimer's disease (AD), an irreversible neurodegenerative disorder, is linked to abnormal protein cleavage and potentially involves microbiologic components, including gram-positive cocci. Research suggests the presence of bacteria such as Porphyromonas, Actinomyces, and Treponema in autopsied AD brains. Investigating the microbiologic connection between PD and AD is crucial, considering …
