Opening Space For Joy: Play As A Pathway In Dance/Movement Therapy With Adults In Addiction Recovery, Brittany M. Walsh May 2026

Opening Space For Joy: Play As A Pathway In Dance/Movement Therapy With Adults In Addiction Recovery, Brittany M. Walsh

Expressive Therapies Theses

This literature review examines the cultivation of joy through play in dance/movement therapy (DMT) for adults in addiction treatment. Substance use disorders (SUDs) and addictive behaviors are complex, multifaceted conditions influenced by biological, psychological, social, and systemic factors; however, treatment approaches often prioritize symptom reduction and traditional talk-based models. Although necessary, these approaches often fail to honor the whole person, and can inadvertently reinforce shame, stigma, isolation, and dehumanization. Drawing on trauma-informed, neurobiological, relational, and decolonizing frameworks, this review positions joy as a fundamental aspect of human experience and an affirmation of dignity. Playful processes in DMT have the potential …

Critical evaluation and refinement of animal models is essential for neuroscientists to understand complex physiological and pathological processes related to psychiatric diseases. In general, preclinical studies modeling drug dependence and problematic substance use have been limited to the administration of a single substance; however, there is a growing appreciation that this approach has failed to capture the complexities of humans and has stifled translational efforts. Polysubstance use represents the overwhelmingly common patterns of alcohol and drug use in humans. For example, epidemiological studies generally determine that between 70–95 % of individuals with alcohol use disorder use tobacco daily, and upwards …

Genes influencing opioid use disorder (OUD) biology have been identified via genome-wide association studies (GWAS), gene expression, and network analyses. These discoveries provide opportunities to identifying existing compounds targeting these genes for drug repurposing studies. However, systematically integrating discovery results and identifying relevant available pharmacotherapies for OUD repurposing studies is challenging. To address this, we've constructed a framework that uses existing results and drug databases to identify candidate pharmacotherapies. For this study, two independent OUD related meta-analyses were used including a GWAS and a differential gene expression (DGE) study of post-mortem human brain. Protein-Protein Interaction (PPI) sub-networks enriched for GWAS …


Hdac5 Enzymatic Activity Regulates Scn4b Expression To Control Relapse-Like Cocaine Seeking, Daniel J. Wood Apr 2025

Hdac5 Enzymatic Activity Regulates Scn4b Expression To Control Relapse-Like Cocaine Seeking, Daniel J. Wood

MUSC Theses and Dissertations

Substance Use Disorder (SUD) is a relapsing disorder characterized by repeated seeking and use of psychoactive substances despite negative consequences to the individual. Epigenetic changes within the medium spiny neurons (MSNs) of the nucleus accumbens (NAc) are thought to underly the lasting propensity to relapse in SUD. The epigenetic enzyme histone deacetylase 5 (HDAC5) in NAc MSNs limits the formation of reward-cue associations in rodent models of drug seeking, but not sucrose seeking, leading to decreased relapse-like behavior. However, whether HDAC5 reduces drug seeking behavior through its own deacetylase activity or through the recruitment of co-repressors is unknown. Furthermore, these …

Structural and functional alterations in the brain's reward circuitry are present in cocaine use disorder (CocUD), but their molecular underpinnings remain unclear. To investigate these mechanisms, we performed single-nuclei multiome profiling on postmortem caudate nucleus tissue from six individuals with CocUD and eight controls. We profiled 30,030 nuclei, identifying 13 cell types including D1- and D2-medium spiny neurons (MSNs) and glial cells. We observed 1485 differentially regulated genes and 10,342 differentially accessible peaks, with alterations in MSNs and astrocytes related to neurotransmitter activity and synapse organization. Gene regulatory network analysis identified transcription factors including ZEB1 as exhibiting distinct CocUD-specific subclusters, …


A Long Non-Coding Erna Forms R-Loops To Shape Emotional Experience-Induced Behavioral Adaptations, Rose Marie Akiki Apr 2025

A Long Non-Coding Erna Forms R-Loops To Shape Emotional Experience-Induced Behavioral Adaptations, Rose Marie Akiki

MUSC Theses and Dissertations

Emotional experiences often evoke neural plasticity that supports adaptive changes in behavior, including maladaptive plasticity associated with mood and substance use disorders. These adaptations are supported in part by experience-dependent activation of immediate-early response genes, such as Npas4. We discovered that a conserved, long non-coding enhancer RNA (lnc-eRNA) transcribed from an activity-sensitive enhancer produces DNA-RNA hybrid R-loop structures that support 3D chromatin-looping of the enhancer and proximal promoter and stimulus-induced, rapid Npas4 gene induction. We also show that this Npas4 lnceRNA and its R-loops are required for the development of behavioral adaptations produced by chronic psychosocial stress or cocaine exposure, …


Opioid Vs. Money Choice Preference Patterns In Regular Heroin Users, Amolak S. Jhand, Mark Greenwald Apr 2025

Opioid Vs. Money Choice Preference Patterns In Regular Heroin Users, Amolak S. Jhand, Mark Greenwald

Medical Student Research Symposium

About two-thirds of people treated for opioid use disorder (OUD) return to opioid use within the first-year post-treatment, and about 10% report use while on agonist therapy. Understanding determinants of opioid-seeking is vital to reducing recurrence and its risks. We assessed individual differences in effortful choices between opioid and money amounts, modeling real-world choices.

Our lab conducted studies in which regular heroin-users were stabilized on buprenorphine to suppress withdrawal. Within experimental sessions, the participant could choose repeatedly across 12 trials between units of hydromorphone (HYD, 1 or 2 mg IM) vs. money ($2 or $4); HYD and money amounts differed …


Brain On Drugs: The Rewarding And Punishing Effects Of Addiction And Relapse, Abby Ferrell Jan 2025

Brain On Drugs: The Rewarding And Punishing Effects Of Addiction And Relapse, Abby Ferrell

Undergraduate Honors Theses

Addiction is a multidimensional disorder that is heavily influenced by behavior, biology, and social interaction. These factors work together to make addiction persist and make relapse easier. Three major models of addiction are explored--behaviorism, biology, and social learning theory, which all contribute to the understanding of addiction, and their respective treatments can be individual, and when integrated. Behavior models highlight how conditioning and reinforcement contribute to addiction, while biological studies focus on dopamine changes in the brain that alter other areas of brain chemistry. Social learning theories add to the environmental cue associations that behaviorism mentions briefly. The implications that …

Weighted Family History Density Of Substance Use: Influence On Participant Substance Use Onset, Escalation, And Duration, Carleigh A. Litteral

Theses and Dissertations--Psychology

Substance use disorders impose a staggering toll on the United States (U.S.), straining healthcare systems, destabilizing communities, and profoundly impacting both individuals and families. Approximately one in six Americans aged 12 and older had a past-year substance use disorder in 2022 (Key Substance Use, 2022), and nearly one-third of adults experience a substance use disorder in their lifetime (Wu, 2010), contributing to an economic burden exceeding $400 billion annually (National Drug Threat Assessment, 2011). Family history of substance use disorders is a key predictor of vulnerability, with individuals who have affected relatives being 2–8 times more …

Individual Differences In Cannabis Use Disorder With Implications For Endocannabinoid Modulation In Therapeutics Development, Erin L. Martin Apr 2024

Individual Differences In Cannabis Use Disorder With Implications For Endocannabinoid Modulation In Therapeutics Development, Erin L. Martin

MUSC Theses and Dissertations

Cannabis use disorder (CUD) is increasingly prevalent in the United States, but there is no effective pharmacological means to treat it. The endocannabinoid (eCB) system has emerged as a candidate therapeutic target demonstrating some evidence of efficacy in treating CUD. However, clinical trials evaluating eCB-modulating therapeutics have historically undervalued individual differences that could contribute to variation in treatment outcome (e.g. sex, comorbid psychiatric illness). To address this gap in the literature, the present set of studies (a) compared plasma eCB tone in groups underrepresented in treatment trials for CUD (females, individuals with comorbid major depressive disorder; MDD/CUD) with males or …

Examination Of Reward Processing Dysfunctions In The Left Dorsal Striatum And Other Brain Regions Among Psychiatric Inpatients With Substance Use, Julia Myerson, Mario Montelongo, Katrina Rufino, Michelle Patriquin, Ramiro Salas, Hyuntaek Oh

Staff and Researcher Publications

Background: Substance misuse is a major public health issue and research has established attenuated reward responses to drug cues in those who misuse substances. Yet, little is known about whether the expectation of natural reinforcers engages distinct brain regions in substance misuse.

Methods: Using functional magnetic resonance imaging (fMRI), we delivered juice at expected and unexpected times to examine reward processing dysfunctions. We focused on the responses within the left dorsal striatum (DS) in individuals with high-risk substance use (HRU, n = 65), low-risk substance use (psychiatric controls, PC, n = 65), and healthy controls (HC, n = 65). Additionally, …


Estradiol Signaling Improves Extinction Memory Recall To Combat Cue-Induced Heroin Relapse In Rats, Jordan S. Carter Jan 2024

Estradiol Signaling Improves Extinction Memory Recall To Combat Cue-Induced Heroin Relapse In Rats, Jordan S. Carter

MUSC Theses and Dissertations

We are in the midst of an opioid use disorder (OUD) epidemic. While several treatments mitigate a range of factors contributing to return to use, or relapse, the power of drug-conditioned environmental cues to precipitate relapse have not been adequately addressed. One treatment modality targeting cue reactivity, cue exposure therapy (CET), exacerbated relapse in individuals with OUD, perhaps due to a deficit in extinction memory recall (EMR). Here, EMR is the ability to override the drug-cue association and prevent relapse. Interest remains in combatting cue-induced relapse, potentially by introducing a pharmacologic adjunct with CET to enhance EMR. In the following …

‘Things That You Can’T Really Suppress’: Adverse Childhood Experiences In The Narratives Of People With Opioid Use Disorder, Sydney Silverstein, Josef Rivera, Danielle Gainer, Raminta Daniulaityte

Psychiatry Faculty Publications

While numerous studies have established relationships between Adverse Childhood Experiences (ACEs) and adult substance use, few qualitative studies have explored the differing ways in which experiences of childhood adversity are emplotted into narratives of drug use and recovery. This paper analyzes qualitative data collected as part of a mixed-methods longitudinal study of people with opioid use disorder. Narratives of adverse childhood experiences emerged unprompted. After coding qualitative data for mention of ACEs, we thematically analyzed coded data using a framework of critical phenomenology and constructed a four-part typology to differentiate the ways that ACEs were emplotted into narratives. Our …

Alcohol use disorder (AUD) produces cognitive deficits, indicating a shift in prefrontal cortex (PFC) function. PFC glutamate neurotransmission is mostly mediated by α-amino-3‑hydroxy-5-methyl-4-isoxazolepropionic acid-type ionotropic receptors (AMPARs); however preclinical studies have mostly focused on other receptor subtypes. Here we examined the impact of early withdrawal from chronic ethanol on AMPAR function in the mouse medial PFC (mPFC). Dependent male C57BL/6J mice were generated using the chronic intermittent ethanol vapor-two bottle choice (CIE-2BC) paradigm. Non-dependent mice had access to water and ethanol bottles but did not receive ethanol vapor. Naïve mice had no ethanol exposure. We used patch-clamp electrophysiology to measure …

Electrophysiological Responses To Emotional And Cocaine Cues Reveal Individual Neuroaffective Profiles In Cocaine Users, Heather E Webber, Constanza De Dios, Margaret C Wardle, Robert Suchting, Charles E Green, Joy M Schmitz, Scott D Lane, Francesco Versace

Faculty, Staff and Student Publications

Smokers with stronger neuroaffective responses to drug-related cues compared to non-drug-related pleasant images (C>P) are more vulnerable to compulsive smoking than individuals with the opposite brain reactivity profile (P>C). However, it is unknown if these neurobehavioral profiles exist in individuals abusing other drugs. We tested whether individuals with cocaine use disorder (CUD) show similar neuroaffective profiles to smokers. We also monitored eye movements to assess attentional bias toward cues and we further performed exploratory analyses on demographics, personality, and drug use between profiles. Participants with CUD (n=43) viewed pleasant, unpleasant, cocaine, and neutral images while we recorded electroencephalogram. …


A Pilot Randomized Controlled Trial Evaluating Peer Recovery Coaches For Addiction Recovery Among Indigenous Americans, Nicholas Guenzel Aug 2023

A Pilot Randomized Controlled Trial Evaluating Peer Recovery Coaches For Addiction Recovery Among Indigenous Americans, Nicholas Guenzel

Theses & Dissertations

Addiction is a common and devastating problem among many Indigenous American (IA) groups around the United States. Too few IA health care providers are available to deliver care in a way that leverages IA values and traditions to support addiction recovery. Peer recovery coaches (PRCs) are individuals who have lived experience of addiction and have received specialized training in helping others in recovery. IA PRCs hold significant potential in helping to fill the gap of culturally-specific support in addiction. In this feasibility trial, we recruited a total of 120 adult (≥19 years) IAs with a substance use disorder through Facebook …

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 …

Stress and craving, it has been found, contribute to the development and maintenance of and relapse in cocaine use disorder. Chronic cocaine users (CU), previous research has shown, display altered physiological responses to psychosocial stress and increased vegetative responding to substance-related cues. However, how psychosocial stress and cue-induced craving interact in relation to the CU's physiological responses remains largely unknown. We thus investigated the interaction between acute psychosocial stress and cocaine-cue-related reactivity in 47 CU and 38 controls. In a crossed and balanced design, the participants were randomly exposed to a video-based cocaine-cue paradigm and the Trier Social Stress Test …

How To Survive College As An Acoa: The Effectiveness Of University Resources On Helping Acoas Socially And Psychologically Succeed During Their Academic Career, Kelly Buchan

Senior Theses

In 2019, 14.5 million people ages 12 and older had Alcohol Use Disorder (AUD), but only 10% received treatment (National Institute on Alcohol Abuse and Alcoholism [NIAAA], 2022). Parental drinking problems can directly affect children, or “Adult Children of Alcoholics.” Of the few studies targeting ACoAs, results show that ACoAs not only have higher risks of mental illness, but they also have lower GPAs and social health (Schroeder & Kelley, 2008). Thus, this study assessed the extent to which perceptions of the college drinking environment are related to higher depression rates in ACoAs, certain drinking motivations, and reluctance to use …
