Using Fmri To Assess Effectiveness Of Olanzapine Treatment For Schizophrenia, William Kyle Copenhaver, David F. Lo, Hanna Rothenberg, Eeshan Khurana, Valerie Rome, Uzayr Wasif, Don D. Shamilov

Rowan-Virtua Research Day

Schizophrenia is a complex mental illness with neurobiological underpinnings and misconceptions about violence. Schizophrenia is associated with high levels of creativity and structural traits like fewer D2 receptors. Patients face reduced life expectancy due to cardiovascular diseases and cope through smoking and sedentariness. Treatment involves pharmacological antipsychotics like olanzapine and nonpharmacological approaches. Olanzapine works by antagonizing D2 receptors but has side effects like weight gain and diabetes risk. fMRI is used to study treatment mechanisms and predict response, but research on olanzapine's brain network effects is limited.

Alpha 7 Nicotinic Acetylcholine Receptor Expression In The Hippocampus Of Patients With Schizophrenia, Shruti Varshney, Ananya Nethikunta, Minjal Patel, Mary Kosciuk, Randel L. Swanson, Venkat Venkataraman, Robert Nagele, Eric Goldwaser, Nimish Acharya

Rowan-Virtua Research Day

Background: Schizophrenia (SZ) is a heterogenous psychiatric condition characterized by disruptions in cognition, social activity, affect, and perception often associated with a varied combination of positive and negative symptoms. The pathophysiology behind SZ remains poorly elucidated. Earlier reports have cited the importance of the alpha 7 nicotinic acetylcholine receptors (α7nAChR) in the hippocampus and the receptor’s association with auditory sensory gating and cognitive function. Specifically, variations in the expression and functionality of α7nAChR can be linked to auditory hallucinations experienced by patients with SZ and several therapies have been researched that target α7nAChRs. However, there are very few primary research …

Purpose/Background

Schizophrenia is a lifelong illness with recurrent and often debilitating symptoms that may impair daily functioning, cognition, behaviors, socialization, emotions, and expression. It is recognized as a global mental health burden that affects the individual, their family, and society. Medication nonadherence and resulting relapse detrimentally affect the patient’s physical and mental health and quality of life. They are associated with increased hospitalization and emergency room visits, substance use, suicide, and homelessness. Current guidelines endorse second-generation antipsychotics such as Risperidone and Aripiprazole as the first-line treatment for most cases of psychosis. However, long-acting injectable (LAIs) atypical antipsychotics are a promising …


The Image Of Schizophrenia In Spain's Healthcare System, Meghan Webb Jan 2024

The Image Of Schizophrenia In Spain's Healthcare System, Meghan Webb

CISLA Senior Integrative Projects

Schizophrenia affects thousands of people in Spain and is one of the most serious mental health disorders in existence. Despite its this characteristic, schizophrenia did not always get the proper attention it deserved within the country’s healthcare system. This was largely due to the influence that the Spanish government had, and continues to have, over the healthcare system, giving it the power to choose how the disorder was represented. Therefore, what does that mean for schizophrenia in Spain’s healthcare system today? This essay will explore the ways in which schizophrenia was represented in Spain’s healthcare system through an examination of …


Representation Of Racial And Ethnic Minorities And Their Preferences For Mood Stabilizing Treatment Selection For Bipolar Disorder: A Systematic Review, Francisco J. Barrera, Manuel Gardea, Juan Garzon, Ryan Toledo, Ana Paula Bonner, Andrea Maraboto, Mark Frye, Ihsan Salloum Sep 2023

Representation Of Racial And Ethnic Minorities And Their Preferences For Mood Stabilizing Treatment Selection For Bipolar Disorder: A Systematic Review, Francisco J. Barrera, Manuel Gardea, Juan Garzon, Ryan Toledo, Ana Paula Bonner, Andrea Maraboto, Mark Frye, Ihsan Salloum

Research Symposium

Background: The use of second-generation antipsychotics for bipolar disorder (BD) has increased in the past years1Concerns on potential serious medical side effects and need for blood level monitoring of some traditional mood stabilizers along with other factors have influenced this change. Shared decision-making (SDM) strategies have been implemented in clinical settings due to their ability to engage patients in the process of treatment selection.2 Within minority groups with mental illnesses, socioeconomic factors, individual concerns, and cultural variations in clinical presentations, are often overlooked or misrepresented when assessing the patient’s treatment preferences. Although several studies evaluating the …

To examine the correlation between variables, Person correlation test was employed. The mean age of the sample was 38.32±12.32 years and 66% of the patients were males. Significant correlations were found between all aspects of the quality of life (physical health, psychological, social relationships and environmental health) and total …


Glutamate, And Its Relationship To Task-Induced Functional Connectivity In The Human Brain: A Focus On Schizophrenia, Kathleen Liu Young, John Kopchick, Jeffrey Stanley, Vaibhav Diwadkar Mar 2023

Glutamate, And Its Relationship To Task-Induced Functional Connectivity In The Human Brain: A Focus On Schizophrenia, Kathleen Liu Young, John Kopchick, Jeffrey Stanley, Vaibhav Diwadkar

Medical Student Research Symposium

Glutamate is the brain’s major excitatory neurotransmitter mediating both neuroplasticity and network function (Zhou & Danbolt, 2014). Basal glutamate (Glu) measured using proton magnetic resonance spectroscopy (1H-MRS) provides insight into a region’s density of neuropil related to the glutamatergic system. Moreover, given the role of glutamate in mediating brain network function, Glu levels may play a role in the brain’s functional connectivity (FC), which is typically estimated from functional magnetic resonance imaging (fMRI) time series data. These questions converge when considering the clinical syndrome of schizophrenia (SCZ). Patients with SCZ show abnormalities in basal Glu in the hippocampus and prefrontal …

Supersensitivity Psychosis With Acute Dystonia, Tatiana Nunez, Gabriella Meyerson, Mays Alani, Shahid Elahi, Enrique Vargas

HCA Healthcare Journal of Medicine

Introduction

Supersensitivity psychosis is a phenomenon that occurs with chronic usage of antipsychotics secondary to treatment resistance. At this time, there are no standardized guidelines regarding the management of supersensitivity psychosis.

Case Presentation

We present a case of a patient with schizoaffective disorder who developed supersensitivity psychosis and acute dystonia in response to discontinuing psychotropic medications, including high-dose quetiapine and olanzapine. The patient presented with excessive anxiety, paranoia, bizarre thoughts, and generalized dystonia affecting the face, trunk, and extremities. We treated the patient with olanzapine, valproic acid, and diazepam, which alleviated the psychosis back to baseline and significantly improved the …


Data-Driven Neuroanatomical Subtypes In Various Stages Of Schizophrenia: Linking Cortical Thickness, Glutamate, And Language Functioning, Liangbing Liang Dec 2022

Data-Driven Neuroanatomical Subtypes In Various Stages Of Schizophrenia: Linking Cortical Thickness, Glutamate, And Language Functioning, Liangbing Liang

Electronic Thesis and Dissertation Repository

The considerable variation in the spatial distribution of cortical thickness changes has been used to parse heterogeneity in schizophrenia. We aimed to recover a ‘cortical impoverishment’ subgroup with widespread cortical thinning. We applied hierarchical cluster analysis to cortical thickness data of three datasets in different stages of psychosis and studied the cognitive, functional, neurochemical, language and symptom profiles of the observed subgroups. Our consensus-based clustering procedure consistently produced a subgroup characterized by significantly lower cortical thickness. This ‘cortical impoverishment’ subgroup was associated with a higher symptom burden in a clinically stable sample and higher glutamate levels with language impairments in …


Sexual Obsessions In A Patient With Schizophrenia, Mohsin Raza, Barbara L. Gracious Oct 2022

Sexual Obsessions In A Patient With Schizophrenia, Mohsin Raza, Barbara L. Gracious

HCA Healthcare Journal of Medicine

Obsessive-compulsive symptoms in schizophrenia are often initially unrecognized or missed entirely in the diagnostic process. Sexual obsession is common in patients with schizophrenia. Therefore, identifying sexual obsession early in treatment has significant implications for appropriate multidisciplinary management and prognosis. We report the case of a Hispanic male in his 20s who presented with self-injurious behavior and worsening psychotic symptoms in the context of a recent diagnosis of schizophrenia and without a past diagnosis or historical symptoms of obsessive-compulsive disorder (OCD). This report elucidates the importance of identifying the underlying cause of self-injurious behavior, which in this young man was due …


Gender Dysphoria Versus Acute Psychosis: Can One Properly Diagnose Gender Dysphoria Solely During Acute Psychosis?, Kristy A. Fisher, Samantha Scemla, Clara L. Alvarez Villalba, Jessica Kroin Jun 2022

Gender Dysphoria Versus Acute Psychosis: Can One Properly Diagnose Gender Dysphoria Solely During Acute Psychosis?, Kristy A. Fisher, Samantha Scemla, Clara L. Alvarez Villalba, Jessica Kroin

HCA Healthcare Journal of Medicine

Gender dysphoria occurs when a discrepancy between one’s sex assigned at birth and one’s gender identity causes distress or impairment in function, which can lead ultimately to seeking treatment in the forms of psychotherapy, hormonal therapy, and/or gender-affirming surgery. Clinical care guidelines also recommend pharmacological treatment of psychiatric comorbidities if indicated. A review of the current literature demonstrates comorbidity between gender dysphoria and psychosis, including cases of gender dysphoria with schizophrenia and the occurrence of gender dysphoria symptoms during manic or psychotic episodes. The existing literature has yet to specifically examine gender dysphoria amongst individuals with schizoaffective disorder. The authors …


Through The Cracks: The Disposition Of Patients With Schizophrenia Spectrum Disorders In The Post-Asylum Era, Briana Tillman, Erin Smith, Alicia Cho, Colt Kennington, Alexandra Kreis Jun 2022

Through The Cracks: The Disposition Of Patients With Schizophrenia Spectrum Disorders In The Post-Asylum Era, Briana Tillman, Erin Smith, Alicia Cho, Colt Kennington, Alexandra Kreis

HCA Healthcare Journal of Medicine

This paper aims to explore current disposition options for patients with psychosis in light of shifts toward community care and changes in mental healthcare funding in the post-asylum era and to propose systemic-level improvements based upon local successes. It evaluates critiques of long-term psychiatric care programs, claims of transinstitutionalization to incarceration, shelters, and emergency rooms, and programs initiated to address deinstitutionalization. The authors conclude that while Assertive Community Treatment, Partial Hospitalization Programs, intermediate-level care, and housing interventions can improve outcomes for many persons with psychotic illness, a significant portion of these patients would still be best served in long-term psychiatric …

Indian Journal of Research in Homoeopathy

Introduction: Schizophrenia is a complex, progressive and severe mental disorder characterised by distortions in thinking, perception, emotions, language, sense of self and behaviour. Conventional medication and cognitive behaviour therapy are used in the treatment of schizophrenia. Homoeopathy can also offer promising results in schizophrenia as evident from the previous studies. Case Summary: Five patients reported at the outpatient department of National Homoeopathy Research Institute in Mental Health, Kerala, India, with symptoms of schizophrenia were treated with individualised homoeopathic medicine as an add-on therapy to conventional medicines. Assessment of the patients was done using three scales: Positive and Negative Syndrome Scale, …


A Life Lived With Schizophrenia: When Mother’S Love Is Kept In The Dark Exploring Maternal Communication And Attachment Organization In Families With Schizophrenia, Myrsini Stefanidou Marini May 2022

A Life Lived With Schizophrenia: When Mother’S Love Is Kept In The Dark Exploring Maternal Communication And Attachment Organization In Families With Schizophrenia, Myrsini Stefanidou Marini

Electronic Theses and Dissertations

In recent years, research into the transgenerational transmission of attachment styles has shown that a mother’sattachment style often predicts the attachment style of her infant. Fearsome parental behavior has been found to predict disorganized attachment in infants, which is further associated with a range of mental health disturbances in adolescence. Furthermore, regular patterns of disturbed communication between mother and child have also been found to lead to ‘schizophrenic’ thinking and behavior in the child’s life. While acknowledging that genetic and other biological factors contribute to the emergence of schizophrenia, this study focused on disorganized attachment and disturbed communication between mother …

A Comparison Of Stigma Levels For Individuals With Psychological Disorders And Individuals With Intellectual Disabilities, Isabella E. Wood Apr 2022

A Comparison Of Stigma Levels For Individuals With Psychological Disorders And Individuals With Intellectual Disabilities, Isabella E. Wood

Honors Theses

This study compared nine aspects of stigmatization (blame, anger, pity, help, dangerousness, fear, avoidance, segregation, coercion) amongst schizophrenia, binge eating, and intellectual disabilities. The overall MANOVA was significant, F(18, 183) = 89.95, p < .001, Wilks’ Lambda = .10. When the results for the dependent variables were considered separately, all nine dependent variables reached significance (p < .001). Schizophrenia scored highest in all categories except blame and pity. Blame was the highest for binge eating and pity was the highest for intellectual disabilities. Efforts to reduce stigmatization must be tailored to each disorder.

Hallermann-Streiff Syndrome And Psychosis: A Case Report, Tarvis Peacock, Ubaid Khokhar, Jaclyn Murphy, Zach Murphy

HCA Healthcare Journal of Medicine

Hallermann-Streiff syndrome is a rare genetic congenital disorder, with fewer than 200 cases reported to date, that is characterized by brachycephaly with frontal bossing, micrognathia, a “bird-like” beaked nose, microphthalmia with congenital cataracts, dental abnormalities, hypotrichosis, skin atrophy, and short stature. There is limited data on psychosis in individuals with Hallermann-Streiff syndrome; the information available depicts mania rather than psychosis. This case report reviews the presentation and treatment of psychosis in a 32-year-old male with Hallermann-Streiff syndrome who was involuntarily admitted to an inpatient psychiatric unit for persecutory delusions and hallucinations. The patient’s psychosis responded well to risperidone with a …


Examination Of Common And Rare Variant Genetic Architecture Of Psychiatric Disorders, Mohammad Ahangari Jan 2022

Examination Of Common And Rare Variant Genetic Architecture Of Psychiatric Disorders, Mohammad Ahangari

Theses and Dissertations

Psychiatric disorders are often heterogenous in their manifestation and genome-wide association studies have identified many common risk variants involved in their polygenic architectures with varying degrees of pleiotropy. In recent years, large-scale biobanks have also begun sequencing the genome of their participants to elucidate the role of rare risk variation in the genetic architecture of complex phenotypes, including psychiatric traits. This dissertation sought to better understand the role of both common and rare risk variation in the genetic architecture of psychiatric disorders with a particular focus on schizophrenia and alcohol problems. In the first three analyses, we focused on characterizing …


Telemedicine In Schizophrenia, Stacy H. Williams Apr 2021

Telemedicine In Schizophrenia, Stacy H. Williams

MSN Capstone Projects

Schizophrenia is a chronic neurological brain disorder that affects approximately 2.6 million adults in the United States alone. This condition affects twenty million people worldwide according to the World Health Organization. “Patients with schizophrenia often die at a considerably younger age than the rest of the population,” (Wallace, 2017). The treatment of this condition is complex because of the array of different symptoms and presented behaviors. Treatment consists of targeting the symptoms. This is done with medication and psychotherapeutics treatments. ‘Despite continued therapeutic advances, the life expectancy of patients with schizophrenia is reduced by approximately 10-25 years compared to that …


Learning Without Contingencies Induces Higher Order Asynchrony In Brain Networks In Schizophrenia, Elizabeth L. Martin, Asadur Chowdury, Vaibhav Diwadkar, Sazid Hasan, Munajj Ul-Huq, Shahira Baajour, Dalal Khatib, Usha Rajan, Jeffrey Stanley Feb 2021

Learning Without Contingencies Induces Higher Order Asynchrony In Brain Networks In Schizophrenia, Elizabeth L. Martin, Asadur Chowdury, Vaibhav Diwadkar, Sazid Hasan, Munajj Ul-Huq, Shahira Baajour, Dalal Khatib, Usha Rajan, Jeffrey Stanley

Medical Student Research Symposium

Schizophrenia (SCZ) is characterized by both cognitive and reward impairments. A recent study suggests that SCZ is associated with a loss of synchrony between learning and reward circuits (Robison et al., 2019) and higher levels of dis-organization of functional brain networks may underpin failures in learning that characterize SCZ (Hütt et al., 2014). Therefore, here we examined inter-group (HC ≠ SCZ) 4th order differences in statistical regularity across a connectome of cognition and reward brain circuits. The analyses were conducted on fMRI time series data from a previous learning paradigm (Stanley et al., 2017) with periods of Encoding and …

Pharmacy Faculty Articles and Research

Primary cilia function as cells' antennas to detect and transduce external stimuli and play crucial roles in cell signaling and communication. The vast majority of cilia genes that are causally linked with ciliopathies are also associated with neurological deficits, such as cognitive impairments. Yet, the roles of cilia dysfunctions in the pathogenesis of psychiatric disorders have not been studied. Our aim is to identify patterns of cilia gene dysregulation in the four major psychiatric disorders: schizophrenia (SCZ), autism spectrum disorder (ASD), bipolar disorder (BP), and major depressive disorder (MDD). For this purpose, we acquired differentially expressed genes (DEGs) from the …

There are several advancements in genomics under specific categories, such as cancer and autism. Mental health is one of the leading diseases to cause a significant debt burden in today's society. However, genomics has not translated well into mental health treatment. One area of focus is schizophrenia. Those with schizophrenia suffer from severe and devastating symptoms. The symptoms can lead to harsh complications. Which can make it impossible to function in everyday life. Many believe it is not just genetics alone, but also environmental factors that contribute to schizophrenia. Through large genome-wide associated studies, discoveries are being made. There have …


Assessing The Effect Of Chronic Dopamine Receptor 2 Blockade As A Potential Model Of Secondary Negative Symptoms In Rats Using The Fr5/Chow Feeding Choice Task, Cyrene Nicholas May 2020

Assessing The Effect Of Chronic Dopamine Receptor 2 Blockade As A Potential Model Of Secondary Negative Symptoms In Rats Using The Fr5/Chow Feeding Choice Task, Cyrene Nicholas

Honors Scholar Theses

Haloperidol, a dopamine (DA) D2 receptor antagonist, is an antipsychotic drug which is commonly used to treat schizophrenia and other psychiatric disorders. These disorders are often characterized by elevated striatal dopamine, which is speculated to have a role in producing positive symptoms such as hallucinations, delusions, and paranoia, as well as symptoms related to motivational salience and reward prediction. Individuals with schizophrenia also exhibit negative symptoms, such as amotivation, anergia, fatigue, and apathy among others. While some negative symptoms of schizophrenia are inherent to the pathophysiology, other negative symptoms are hypothesized to be partially induced by chronic exposure to antipsychotic …


Exploring The Heteromeric Interface Of The 5-Ht2a-Mglu2 Receptor Complex, Mohamed Aarif Abdul Kareem Jan 2020

Exploring The Heteromeric Interface Of The 5-Ht2a-Mglu2 Receptor Complex, Mohamed Aarif Abdul Kareem

Theses and Dissertations

Schizophrenia is a serious mental disorder characteristic of several neurotransmitters including dopamine, serotonin, and glutamate being in imbalance. Early therapies focused solely on dopamine antagonism and second-generation antipsychotics focused on the dopamine and serotonin systems and their respective G protein coupled receptor (GPCR) proteins. Although debate for dimerization of certain classes of GPCR exist, the establishment of an mGlu2-5-HT2A heterocomplex, which is implicated in schizophrenia is of interest. Previous studies have used a mutation-based approach to identify transmembrane domain 4 (TM4) as the domain responsible in mGlu2 for mediating heteromerization before narrowing down the individual amino acids responsible for …
