Mdma-Assisted Psychotherapy For Posttraumatic Stress Disorder: A Review Of The Literature, Erin Solomon May 2018

Mdma-Assisted Psychotherapy For Posttraumatic Stress Disorder: A Review Of The Literature, Erin Solomon

Student Works

A growing number of people suffer chronic, treatment-resistant posttraumatic stress disorder (PTSD; Amoroso & Workman, 2016; Buoso, Doblin, Farré, Alcázar, & Gómez-Jarabo, 2008; Mithoefer, Wagner, Mithoefer, Jerome, & Doblin, 2011; Oehen, Traber, Widmer, & Schnyder, 2013). The most popular treatments, including exposure therapy, may not be effective for some people (Amoroso & Workman, 2016; Mithoefer et al., 2011). Treatment dropout and suicidality are high among people for whom therapy is minimally effective (Amoroso, 2015; Amoroso & Workman, 2016; Mithoefer et al., 2011; Oehen et al., 2013). Researchers have begun to investigate 3,4-methylenedioxymethamphetamine (MDMA)-assisted psychotherapy as a possible treatment for PTSD …


Dancing, Mindfulness, And Our Emotions: Embracing The Mind, Body, And Sole, Alisha M. Collins May 2018

Dancing, Mindfulness, And Our Emotions: Embracing The Mind, Body, And Sole, Alisha M. Collins

Dissertations, Theses, and Capstone Projects

This capstone project examines dance, as an intervention and mindfulness practice that assists with managing our emotions. There is a need for dance therapy in social institutions such as, healthcare facilities, schools, and community centers. Dance therapy has the potential to reduce negative emotions, create mindfulness, improve self-expression, and promote a healthy well-being. I am proposing that dance therapy is applied as a regular practice in social institutions to develop mindfulness and promote emotional stability.

In this study, I argue that dance therapy can contribute to our well-being long term. In addition to this written thesis, a visual component of …


The Comparison Of Effective Education Methods To Increase Knowledge About Alzheimer's Disease., Lillian M. Kopsolias May 2018

The Comparison Of Effective Education Methods To Increase Knowledge About Alzheimer's Disease., Lillian M. Kopsolias

College of Arts & Sciences Senior Theses

Alzheimer’s disease (AD) is a disease most people recognize, but have many misconceptions about. One way to decrease the amount of misconceptions about AD is to educate the general public on the disease. Many educational methods, such as person-centered care education, have been researched, but none have focused on the general public. Therefore, the purpose of this study is to compare two educational methods used today, reading a passage from a reliable online source (traditional educational method) and watching documentaries (person-centered care educational method), to find if a specific way of presenting them will prove efficient for Alzheimer’s education. The …


Effort-Related Decision Making In Comt Variant Mice: Pharmacological Studies And Genetic Susceptibility To Motivational Dysfunction, Suzanne Cayer May 2018

Effort-Related Decision Making In Comt Variant Mice: Pharmacological Studies And Genetic Susceptibility To Motivational Dysfunction, Suzanne Cayer

Honors Scholar Theses

Effort-related decision making tasks in animals can model motivational symptoms in humans, which are a set of symptoms spanning a multitude of neuropsychiatric disorders, such as major depressive disorder and the negative symptoms of schizophrenia. The present studies aimed to evaluate the effort-related effects of the Val158Met polymorphism of human catechol-methyltransferase (COMT), by testing mice carrying either the human COMT Val (n=8) or Met allele (n=8) with Wild-Type control mice (n=15) by using concurrent FR2 and FR4/pellet choice tasks in a touchscreen operant conditioning apparatus. The Val158Met polymorphism has been repeatedly associated with neuropsychiatric disorders, and the Val allele has …


Insane: James Holmes, Clark V. Arizona, And America's Insanity Defense, Eric Collins May 2018

Insane: James Holmes, Clark V. Arizona, And America's Insanity Defense, Eric Collins

Journal of Law and Health

Insanity is a legal term of art that changes definitions depending on the legal standard in American jurisprudence, which explains why a man who mental health professionals described as having an uncontrollable obsession with killing people can be found not insane and guilty. This Note addresses the current state of the Insanity Defense Reform Act of 1984 and its widespread implementation at the state level. Part II supplies background information on the history of the insanity defense and how it has transformed over the years in American jurisprudence. Part III provides an analysis of the of the insanity defense. Part …


Post-Traumatic Stress Disorder: Review Of Dsm Criteria And Functional Neuroanatomy, Cornelius W. Thomas Apr 2018

Post-Traumatic Stress Disorder: Review Of Dsm Criteria And Functional Neuroanatomy, Cornelius W. Thomas

Marshall Journal of Medicine

The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria for post-traumatic stress disorder (PTSD) consist of over twenty possible symptoms that can be divided into six broad categories. These categories correlate with specific brain networks that regulate emotions, behaviors, and autonomic function. Normal functioning of these networks depends on two key regions; the prefrontal cortex and the amygdala. The prefrontal cortex provides top-down executive control over amygdala, whereas the amygdala is critical for threat detection and activation of the ‘fight or flight’ response. Events that trigger extreme and/or prolonged fear can cause persisting dysregulation within the prefrontal-amygdala circuit; resulting …


Science, Mental Illness, And Ethics In Friedrich Dürrenmatt’S The Physicists, Niyant Vora Apr 2018

Science, Mental Illness, And Ethics In Friedrich Dürrenmatt’S The Physicists, Niyant Vora

John Wesley Powell Student Research Conference

In 1962, as Cold War tensions approached their peak, Friedrich Dürrenmatt, a Swiss playwright, published his play The Physicists. Two of the most important topics in The Physicists are mental illness and ethical responsibility of scientists. Dürrenmatt’s three main characters: Möbius (a genius), Einstein (a Russian spy), and Newton (an American spy) are all physicists who appropriate the status of mentally ill in order to hide from society inside the Les Cerisiers Sanatorium. Their status as mentally ill acts as a cover up that reveals their different reasons for adapting that status–from Möbius attempt to escape the politics of …


The Relation Of Seasonal Patterns To Mood Changes And Gender Differences In College-Aged Students, Mariah Meza Apr 2018

The Relation Of Seasonal Patterns To Mood Changes And Gender Differences In College-Aged Students, Mariah Meza

Student Research Posters

This study examined college students’ moods during different seasons patterns throughout the year. Previous research has indicated that many individuals feel more lethargic, lonely and moody during the winter months (Rohan & Sigmon, 2000). These mood and behavior patterns clearly depend on specific seasons of the year. However, many studies have produced inconsistent findings and current data on how weather impacts college aged students moods in California (Lucht & Kasper, 1999). There are many inconsistent studies in the United States that indicate whether there is a higher fluctuation in women’s moods during seasonal change than there is with men(Chotai, Smedh, …

Inhibition Of Tnf-Alpha Decreases Microglia Activation In Rats Neonatally Treated With Poly I:C, Heath W. Shelton, Russell W. Brown Apr 2018

Inhibition Of Tnf-Alpha Decreases Microglia Activation In Rats Neonatally Treated With Poly I:C, Heath W. Shelton, Russell W. Brown

Appalachian Student Research Forum

Introduction: Current medical treatment for individuals diagnosed with schizophrenia (SCHZ) primarily relies on the inhibition of the dopamine D2 receptor that has been shown to be supersensitive in these patients. Treatment occurs through the use of antipsychotic medication which leads to a number of debilitating dose-dependent side effects, such as weight gain, agranulocytosis, and seizures. Patients diagnosed with SCHZ have also been shown to have increased inflammation in their central nervous system (CNS), particularly within specific brain regions such as the prefrontal cortex and hippocampus. This is in large part due to the interaction between a pro-inflammatory cytokine called …


Practice Standards For Initial Adhd Assessment: A Review, Lauren Spencer Apr 2018

Practice Standards For Initial Adhd Assessment: A Review, Lauren Spencer

Masters Theses & Specialist Projects

There are many challenges that come with diagnosing attentiondeficit/ hyperactivity disorder (ADHD), including shared symptoms with many similar disorders, high comorbidity of other mental disorders, and subjective bias from informant reports. Three clinical guidelines for diagnosing ADHD currently exist, published by the American Academy of Pediatrics (AAP), the National Institute for Health and Care Excellence (NICE), and the American Academy of Child and Adolescent Psychiatry (AACAP). However, these guidelines are outdated as they are based on the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) and do not include more recent research. This project was intended to update …

The Mind-Body Problem; Three Equations And One Solution Represented By Immaterial-Material Data, Ion G. Motofei, David L. Rowland Mar 2018

The Mind-Body Problem; Three Equations And One Solution Represented By Immaterial-Material Data, Ion G. Motofei, David L. Rowland

Journal of Mind and Medical Sciences

Human life occurs within a complex bio-psycho-social milieu, a heterogeneous system that is integrated by multiple bidirectional interrelations existing between the abstract-intangible ideas and physical-chemical support of environment. The mind is thus placed between the abstract ideas/ concepts and neurobiological brain that is further connected to environment. In other words, the mind acts as an interface between the immaterial (abstract/ intangible) data and material (biological) support. The science is unable to conceives and explains an interaction between the immaterial and material domains (to understand nature of the mind), this question generating in literature the mind-body problem. We have published in …


“Capgras” Delusions Involving Belongings, Not People, And Evolving Visual Hallucinations Associated With Occipital Lobe Seizures, Brandon Lilly, Erika Maynard, Kelly Melvin, Suzanne Holroyd Mar 2018

“Capgras” Delusions Involving Belongings, Not People, And Evolving Visual Hallucinations Associated With Occipital Lobe Seizures, Brandon Lilly, Erika Maynard, Kelly Melvin, Suzanne Holroyd

Psychiatry

Capgras syndrome is characterized by the delusional belief that a familiar person has been replaced by a visually similar imposter or replica. Rarely, the delusional focus may be objects rather than people. Numerous etiologies have been described for Capgras to include seizures. Similarly, visual hallucinations, both simple and complex, can occur secondary to seizure activity.We present, to our knowledge, the first reported case of visual hallucinations and Capgras delusions for objects that developed secondary to new onset occipital lobe epilepsy.We then discuss the possible underlying neurologic mechanisms responsible for the symptomatology.

Mental Health Law & Policy Faculty Publications

Objective: The current paper reviews the English-language research on exclusion criteria in bipolar disorder treatment trials and discusses how study samples compare to the general bipolar patient population.

Methods: & Results: Across 8 identified studies of exclusion criteria and their impact, between 55% and 96% of people with bipolar disorder would be excluded from treatment research. The number of exclusion criteria varies across bipolar disorder treatment research, with one study estimate of a median of 7 criteria used across studies. The criteria that excluded the greatest number of potential participants were comorbid substance use disorder, suicidal risk, and comorbid medical …


Sensory, Motor And Process Skills As Compared To Symptom Severity In Adult Patients With Schizophrenia, Lola Halperin Feb 2018

Sensory, Motor And Process Skills As Compared To Symptom Severity In Adult Patients With Schizophrenia, Lola Halperin

Occupational Therapy Faculty Publications

Schizophrenia is a serious mental illness affecting millions of Americans. It is characterized by positive and negative symptoms; cognitive impairments; and sensory, motor, and process skill deficits; as well as compromised motor learning, functional difficulties, and diminished quality of life. Neuroscientists attribute the above deficits to abnormal brain development, exaggerated synaptic pruning, and neurodegenerative processes, causing disrupted connectivity and diminished plasticity in the brain, neurotransmitter dysfunction, and impaired sensory processing.

Presently, there is no cure for schizophrenia. Numerous medications and rehabilitation modalities exist; however, many of the affected individuals continue to struggle daily. Recovery of these individuals implies symptom management …

School of Social Work Faculty Publications and Presentations

Background: The media has devoted significant attention to anecdotes of individuals who post messages on Facebook prior to suicide. However, it is unclear to what extent social media is perceived as a source of help or how it compares to other sources of potential support for mental health problems.

Objective: This study aimed to evaluate the degree to which military veterans with depression use social media for help-seeking in comparison to other more traditional sources of help.

Methods: Cross-sectional self-report survey of 270 adult military veterans with probable major depression. Help-seeking intentions were measured with a modified General Help-Seeking Questionnaire. …


The Proposed Etiologies Of Dissociative Identity Disorder, Jillian Blueford Jan 2018

The Proposed Etiologies Of Dissociative Identity Disorder, Jillian Blueford

The Pegasus Review: UCF Undergraduate Research Journal

Dissociative Identity Disorder (DID) evolves after suffering consecutive, traumatizing forms of abuse during an individual's early years. Repetitive abuse can lead an individual to develop two or more personalities, and then experience memory loss or other cognitive gaps in his or her early childhood that continue to the present day. This can have devastating effects on millions of people because a significant percentage of affected individuals do not recognize the symptoms or choose to believe that DID does not exist. By analyzing the literature currently available, this article creates a central base of popular and emerging models that clinicians use …


Direct And Indirect Influences Of Defendant Mental Illness On Jury Decision Making, Marie Sabbagh Jan 2018

Direct And Indirect Influences Of Defendant Mental Illness On Jury Decision Making, Marie Sabbagh

The Pegasus Review: UCF Undergraduate Research Journal

It is a common misconception that individuals with schizophrenia are significantly more dangerous and violent than individuals free of mental illness. This stigmatization may lead to harsher sentences when people with schizophrenia are involved in criminal activities and sentenced by a jury. This study presented four conditions to which participants were randomly assigned, alone or in a group of three, and were asked to sentence a defendant, either with or without schizophrenia. It was hypothesized that group deliberations would result in more lenient sentences for defendants with schizophrenia as compared to individual deliberations. Furthermore, it was predicted that both group …


The Backward Masking Red Light Effect And Schizotypy: The Influence Of Sex, Diana C. Hernandez, Andrea Y. Ranieri Jan 2018

The Backward Masking Red Light Effect And Schizotypy: The Influence Of Sex, Diana C. Hernandez, Andrea Y. Ranieri

The Pegasus Review: UCF Undergraduate Research Journal

Previous research has shown a unique effect of red light on visual processing related to both schizophrenia and positive schizotypy. The current study examines whether this effect is influenced by sex in a more broadly-defined schizotypy sample. A location backward masking (BM) task with three color background conditions (red, green, and gray) was administered to 34 undergraduate students (59% female) with a high score on the Schizotypal Personality Questionnaire (SPQ) and 39 students (51% female) with a low score. Results revealed that the group by color interaction was significant for the male participants, while it did not approach significance in …


The Rewarding Nature Of Provocation-Focused Rumination In Women With Borderline Personality Disorder: A Preliminary Fmri Investigation, Jessica R. Peters, David S. Chester, Erin C. Walsh, C. Nathan Dewall, Ruth A. Baer Jan 2018

The Rewarding Nature Of Provocation-Focused Rumination In Women With Borderline Personality Disorder: A Preliminary Fmri Investigation, Jessica R. Peters, David S. Chester, Erin C. Walsh, C. Nathan Dewall, Ruth A. Baer

Psychology Faculty Publications

Background: Understanding why individuals with borderline personality disorder (BPD) ruminate on prior provocations, despite its negative outcomes, is crucial to improving interventions. Provocation-focused rumination may be rewarding in the short term by amplifying anger and producing feelings of justification, validation, and increased energy, while reducing self-directed negative affect. If provocation-focused rumination is utilized regularly as a rewarding emotion regulation strategy, it could result in increased activation in reward-related neural regions. The present pilot study examined neural correlates of provocation-focused rumination, relative to other forms of thought, in BPD.

Method: Functional magnetic resonance imaging (fMRI) was utilized to examine this theory …


Investigating Prosodic Accommodation In Clinical Interviews With Depressed Patients, Brian Vaughan, Carolina De Pasquale, Lorna Wilson, Charlie Cullen, Brian Lawlor Jan 2018

Investigating Prosodic Accommodation In Clinical Interviews With Depressed Patients, Brian Vaughan, Carolina De Pasquale, Lorna Wilson, Charlie Cullen, Brian Lawlor

Conference Papers

Six in-depth clinical interviews, involving six elderly female patients (aged 60+) and one female psychiatrist, were recorded and analysed for a number of prosodic accommodation variables.

Our analysis focused on pitch, speaking time, and vowel-space ratio. Findings indicate that there is a dynamic manifestation of prosodic accommodation over the course of the interactions. There is clear adaptation on the part of the psychiatrist, even going so far as to have a reduced vowel-space ratio, mirroring a reduced vowel-space ratio in the depressed patients. Previous research has found a reduced vowel-space ratio to be associated with psychological distress; however, we suggest …


Persistent Stress-Induced Neuroplastic Changes In The Locus Coeruleus/Norepinephrine System, Olga Borodovitsyna, Neal Joshi, Daniel Chandler Jan 2018

Persistent Stress-Induced Neuroplastic Changes In The Locus Coeruleus/Norepinephrine System, Olga Borodovitsyna, Neal Joshi, Daniel Chandler

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Neural plasticity plays a critical role in mediating short- and long-term brain responses to environmental stimuli. A major effector of plasticity throughout many regions of the brain is stress. Activation of the locus coeruleus (LC) is a critical step in mediating the neuroendocrine and behavioral limbs of the stress response. During stressor exposure, activation of the hypothalamic-pituitary-adrenal axis promotes release of corticotropin-releasing factor in LC, where its signaling promotes a number of physiological and cellular changes. While the acute effects of stress on LC physiology have been described, its long-term effects are less clear. This review will describe how stress …


New Ways Of Predicting Efficacy Of Antidepressants, Kayla Ternes Jan 2018

New Ways Of Predicting Efficacy Of Antidepressants, Kayla Ternes

Physician Assistant Scholarly Project Posters

Major depressive disorder (MDD) is a neuropsychiatric condition that is becoming increasingly prevalent in our country. According to Cai, Huang, and Hao (2015), MDD is “common and devastating” (p. 61) and has a very complex pathophysiology. Until recently, a definitive etiology had not been found, however, new evidence has suggested that Brain-derived neurotrophic factor (BDNF) and cognitive-emotional biomarkers may be a key into the mechanism of this disorder.

A literature review of articles found in PubMed, CINAHL, Cochrane Library, and PsychINFO within the last ten years focused on the hypotheses of the pathophysiology of MDD, cognitive-emotional biomarkers, and BDNF. The …


The Moderating Relationship Of Comorbid Psychopathology And Treatment Outcome For Young Adult Offenders In Drug Court, Patrick Mcgonigal, Kathleen A. Moore, Matthew Scott Young Jan 2018

The Moderating Relationship Of Comorbid Psychopathology And Treatment Outcome For Young Adult Offenders In Drug Court, Patrick Mcgonigal, Kathleen A. Moore, Matthew Scott Young

Mental Health Law & Policy Faculty Publications

Title: The moderating relationship of comorbid psychopathology and treatment outcome for young adult offenders in drug court.

Background: The drug court system is an alternative to incarceration that provides offenders with non-violent, substance motivated crimes with an opportunity to dismiss their charges and undergo a rigorous substance abuse treatment program. It is unknown whether drug court is effective for young adult clients and the role of co-occurring psychopathology within this context.

Methods: This study evaluated the overall effectiveness of a drug court system applied to young adult offenders ages 18-26, and additionally explored the moderating relationship of psychiatric symptoms on …

The Duration Of Untreated Psychosis: A Phenomenological Study, Sarah R. Kamens, Larry Davidson, Emily Hyun, Nev Jones, Jill G. Morawski, Matthew M. Kurtz, Jessica Pollard, Gerrit Ian Van Schalkwyk, Vinrod Srihari

Mental Health Law & Policy Faculty Publications

Mounting evidence has indicated that early intervention leads to improved clinical and functional outcomes for young persons experiencing recent onset psychosis. As part of a large early detection campaign, the present study aimed to investigate subjective experiences during the duration of untreated psychosis (DUP), or time between psychosis onset and treatment contact. Participants were 10 young adults participating in early intervention services for psychosis. After DUP was estimated during standardized baseline assessment, participants engaged in qualitative interviews focused on their life experiences prior to treatment and leading up to the present. Mixed methods data analyses compared standardized DUP estimates with …


The Relationship Between Resilience, Coping, And Social Media, Lillian N. Hurley Jan 2018

The Relationship Between Resilience, Coping, And Social Media, Lillian N. Hurley

Masters Theses

This study was designed to explore relationships between measures of resilience, coping strategies, social media usage, and depression. Resilience refers to one's ability to endure and recover from adversity. Many theories about what contributes to the development resilience have been explored without a clear consensus. Taormina (2015) argued that adult personal resilience is comprised of four dimensions - determination, endurance, adapatability, and recuperability. Coping, a construct related to resilience, is the process of regulating emotions, cognition, behavior, physiological responses, and the environment in response to stressful events. Past research indicated those with poorer mental health have the tendency to use …


Shared Genetic And Environmental Influences On Fear, Anxiety, Posttraumatic Stress, And Brain Morphometry, Chelsea Sawyers Jan 2018

Shared Genetic And Environmental Influences On Fear, Anxiety, Posttraumatic Stress, And Brain Morphometry, Chelsea Sawyers

Theses and Dissertations

Anxiety disorders (ADs) and stress-related disorders are some of the most common psychiatric disorders in the United States. Like other c0mplex psychiatric illness, genetics and neuroimaging research has focused on understanding their underlying neurobiology. Areas within the fear-network play important roles in threat perception, fear conditioning/learning, cognitive processing, and modulation of fear responses including contextual modulation and extinction and have been implicated in ADs as well as stress disorders such as posttraumatic stress disorder (PTSD). The primary gap in the current search for underlying biological mechanisms is in whether biomarkers associated with disorders share genetic influences with the disorders they …


Resilience Concepts In Psychiatry Demonstrated With Bipolar Disorder, David G. Angeler, Craig R. Allen, Maj-Liz Persson Jan 2018

Resilience Concepts In Psychiatry Demonstrated With Bipolar Disorder, David G. Angeler, Craig R. Allen, Maj-Liz Persson

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Background: The term resilience describes stress–response patterns of subjects across scientific disciplines. In ecology, advances have been made to clearly distinguish resilience definitions based on underlying mechanistic assumptions. Engineering resilience (rebound) is used for describing the ability of subjects to recover from adverse conditions (disturbances), and is the rate of recovery. In contrast, the ecological resilience definition considers a systemic change: when complex systems (including humans) respond to disturbances by reorganizing into a new regime (stable state) where structural and functional aspects have fundamentally changed relative to the prior regime. In this context, resilience is an emergent property of complex …
