Development Of Schizophrenia In A Genetically Predisposed Individual Following Covid-19, Sung Kang, Jonathan Yuh, Timothy Wong
Development Of Schizophrenia In A Genetically Predisposed Individual Following Covid-19, Sung Kang, Jonathan Yuh, Timothy Wong
Rowan-Virtua Research Day
We present a patient who is a 56-year-old female with a psychiatric history of anxiety disorder and a medical history of hypercholesterolemia and hyperthyroidism, who was admitted to the hospital after a witnessed seizure at an inpatient psychiatric facility. This patient’s family history is significant for her mother experiencing unspecified psychotic disorder that required psychiatric hospitalization. Our patient was first admitted to the psychiatric hospital after exhibiting worsening paranoid delusions and hallucinations that began several months prior. The patient had reportedly begun locking herself in the restroom and screaming “get out, they’re spying on me”, referring to her next-door neighbors …
Schizophrenia And Genomics, Tiffini Lasch
Schizophrenia And Genomics, Tiffini Lasch
Nursing Student Class Projects (Formerly MSN)
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
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
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 …
The Effects Of Two Novel Anti-Inflammatory Compounds On Prepulse Inhibition And Neural Microglia Cell Activation In A Rodent Model Of Schizophrenia, Heath W. Shelton
The Effects Of Two Novel Anti-Inflammatory Compounds On Prepulse Inhibition And Neural Microglia Cell Activation In A Rodent Model Of Schizophrenia, Heath W. Shelton
Electronic Theses and Dissertations
Recent studies have shown elevated neuroinflammation in a large subset of individuals diagnosed with schizophrenia. A pro-inflammatory cytokine, tumor necrosis factor-alpha (TNFα), has been directly linked to this neuroinflammation. This study examined the effects of two TNFα modulators (PD2024 and PD340) produced by our collaborators at P2D Bioscience, Inc., to alleviate auditory sensorimotor gating deficits and reduce microglial cell activation present in the polyinosinic:polycytidylic (Poly I:C) rodent model of schizophrenia. Auditory sensorimotor gating was assessed using prepulse inhibition and microglial activation was examined and quantified using immunohistochemistry and confocal microscopy, respectively. Both PD2024 and PD340 alleviated auditory sensorimotor gating deficits …
Computational Modeling Of Contrast Sensitivity And Orientation Tuning In Schizophrenia, Steven M. Silverstein, Docia L. Demmin, James A. Bednar
Computational Modeling Of Contrast Sensitivity And Orientation Tuning In Schizophrenia, Steven M. Silverstein, Docia L. Demmin, James A. Bednar
MODVIS Workshop
Computational modeling is being increasingly used to understand schizophrenia, but, to date, it has not been used to account for the common perceptual disturbances in the disorder. We manipulated schizophrenia-relevant parameters in the GCAL (gain control, adaptation, laterally connected) model (Stevens et al., 2013), run using the Topographica simulator (Bednar, 2012), to model low-level visual processing changes in the disorder. Our models incorporated: separate sheets for retinal, LGN, and V1 activity; gain control in the LGN; homeostatic adaptation in V1 based on a weighted sum of all inputs and limited by a logistic (sigmoid) nonlinearity; lateral excitation and inhibition in …
Prospective Memory In Schizophrenia: Relationship To Medication Management Skills, Neurocognition And Symptoms In Individuals With Schizophrenia [Pre-Print], Sarah Raskin, Jacqueline Maye, Alexandra Rogers, David Correll, Marta Zamroziewicz, Matthew Kurtz

Objective: Impaired adherence to medication regimens is a serious concern for individuals with schizophrenia
linked to relapse and poorer outcomes. One possible reason for poor adherence to medication is
poor ability to remember future intentions, labeled prospective memory skills. It has been demonstrated
in several studies that individuals with schizophrenia have impairments in prospective memory that are
linked to everyday life skills. However, there have been no studies, to our knowledge, examining the
relationship of a clinical measure of prospective memory to medication management skills, a key element
of successful adherence. Methods: In this Study 41 individuals with schizophrenia and …
