Gut Microbiome And Nutrition Interplay In Regulating And Improving Autism Spectrum Disorder Related Social Symptoms, Irenonsen Juliet Eigbe, Christian Moya Gamboa, Jana Gjini, Jaydeep Mukherjee, Susrut Dube

Rowan-Virtua Research Day

The composition of the gut microbiome has been shown to play a role in the onset of neurological disorders, including Autism Spectrum Disorder(ASD). A small variety of recent research articles identify a possible link between onset and severity of ASD related behaviors and the composition of the gut microbiome. The purpose of this review is to identify gaps in the current understanding of the role that nutrition plays in changing the gut microbiome and subsequently altering the onset and severity of behavioral phenotypes in children with ASD. Inclusion criteria comprises peer-reviewed publications relating to children with autism. Exclusion criteria consists …

Review Of Psychogenic Nonepileptic Seizures And Patient-Centered Approaches To Care, Rabeel Ahmad, Rebekah Dietrich, Munaza Khan

Rowan-Virtua Research Day

Psychogenic nonepileptic seizures (PNES) are defined as involuntary experiential and behavioral responses to internal or external stimuli. They are behaviors, not associated with pathological alterations in the physiology of the brain. Although some of them mimic syncope, they have historically been regarded to clinically resemble epileptic episodes.

There is a multiplicity of different names for this condition. PNES is the most widely used term, though the term "functional seizures" is increasingly used. Alternatives such as "psychogenic seizures," "dissociative seizures," "psychogenic nonepileptic attacks" (PNEA), and "nonepileptic seizures" are also used.

Comparing Cognitive Tests And Smartphone-Based Assessment In 2 Us Community-Based Cohorts., Ileana De Anda-Duran, Preeti Sunderaraman, Edward Searls, Shirine Moukaled, Xuanyi Jin, Zachary Popp, Cody Karjadi, Phillip H Hwang, Huitong Ding, Sherral Devine, Ludy C Shih, Spencer Low, Honghuang Lin, Vijaya B Kolachalama, Lydia Bazzano, David J Libon, Rhoda Au

BACKGROUND: Smartphone-based cognitive assessments have emerged as promising tools, bridging gaps in accessibility and reducing bias in Alzheimer disease and related dementia research. However, their congruence with traditional neuropsychological tests and usefulness in diverse cohorts remain underexplored.

METHODS AND RESULTS: A total of 406 FHS (Framingham Heart Study) and 59 BHS (Bogalusa Heart Study) participants with traditional neuropsychological tests and digital assessments using the Defense Automated Neurocognitive Assessment (DANA) smartphone protocol were included. Regression models investigated associations between DANA task digital measures and a neuropsychological global cognitive

CONCLUSIONS: Our findings demonstrate that smartphone-based cognitive assessments exhibit concurrent validity with a …

Nucleus Accumbens Core Single Cell Ensembles Bidirectionally Respond To Experienced Versus Observed Aversive Events, Oyku Dinckol, Noah Harris Wenger, Jennifer E Zachry, Munir Gunes Kutlu

Fear learning is a critical feature of survival skills among mammals. In rodents, fear learning manifests itself through direct experience of the aversive event or social transmission of aversive stimuli such as observing and acting on conspecifics' distress. The neuronal network underlying the social transmission of information largely overlaps with the brain regions that mediate behavioral responses to aversive and rewarding stimuli. In this study, we recorded single cell activity patterns of nucleus accumbens (NAc) core neurons using in vivo optical imaging of calcium transients via miniature scopes. This cutting-edge imaging methodology not only allows us to record activity patterns …

Estimating Dementia Risk In An African American Population Using The Dctclock, Marissa Ciesla, Jeff Pobst, Joyce Gomes-Osman, Melissa Lamar, Lisa L Barnes, Russell Banks, Ali Jannati, David Libon, Rodney Swenson, Sean Tobyne, David Bates, John Showalter, Alvaro Pascual-Leone

The prevalence of Alzheimer's disease (AD) and related dementias (ADRD) is increasing. African Americans are twice as likely to develop dementia than other ethnic populations. Traditional cognitive screening solutions lack the sensitivity to independently identify individuals at risk for cognitive decline. The DCTclock is a 3-min AI-enabled adaptation of the well-established clock drawing test. The DCTclock can estimate dementia risk for both general cognitive impairment and the presence of AD pathology. Here we performed a retrospective analysis to assess the performance of the DCTclock to estimate future conversion to ADRD in African American participants from the Rush Alzheimer's Disease Research …

A Case Of Acute Disseminated Encephalomyelitis In An Adult Male With Bipolar Disorder, Jinisha Patwa, Tracey Harris

Rowan-Virtua Research Day

Acute disseminated encephalomyelitis (ADEM) is a rare demyelinating disease characterized by inflammation of the brain and spinal cord. The rapidly progressive inflammation in the central nervous system is known to occur in response to a prior infection or immunization.

The clinical signs of ADEM may manifest up to 60 days post illness or vaccination. Some develop encephalopathy and neurologic symptoms which include confusion, psychosis, and tetraparesis. Paresthesia of the limbs and muscular atrophy indicate a worse prognosis and higher risk of relapse as opposed to those with only CNS involvement. A predominantly psychiatric presentation is also possible.

Risk factors include …

A Preliminary Report: The Hippocampus And Surrounding Temporal Cortex Of Patients With Schizophrenia Have Impaired Blood-Brain Barrier, Eric L. Goldwaser, Randel L. Swanson, Edgardo J. Arroyo, Venkat Venkataraman, Mary C. Kosciuk, Robert G. Nagele, L. Elliot Hong, Nimish K. Acharya

Schizophrenia (SZ) is one of the most severe forms of mental illness, yet mechanisms remain unclear. A widely established brain finding in SZ is hippocampal atrophy, and a coherent explanation similarly is lacking. Epidemiological evidence suggests increased cerebrovascular and cardiovascular complications in SZ independent of lifestyle and medication, pointing to disease-specific pathology. Endothelial cell contributions to blood-brain barrier (BBB) compromise may influence neurovascular unit and peripheral vascular function, and we hypothesize that downstream functional and structural abnormalities may be explained by impaired BBB.

Affective Disturbance In Mild Cognitive Impairment, Jason Greenhagen, Emily Matusz, Sheina Emrani, David Libon, Sherry Pomerantz

Rowan-Virtua Research Day

Mild cognitive impairment (MCI) is an identifiable, prodromal stage of cognitive impairment and has been further defined into subtypes: amnestic, language, executive functioning, and multi domain/mixed MCI (Jak et al. 2009 ). The purpose of this study is to (1) examine the differences in depression, anxiety, and apathy between MCI subtypes; and (2) assess the relationship between the neurocognitive domains (executive functioning, language, and memory and affective symptoms. We hypothesize that apathy will be greater in dysexecutive/mixed MCI (dys/mixed MCI) and be more highly correlated to neurocognitive deficits compared to depression or anxiety. This is a retrospective study of 113 …

Prefrontal Corticotropin-Releasing Factor (Crf) Neurons Act Locally To Modulate Frontostriatal Cognition And Circuit Function., Sofiya Hupalo, Andrea J Martin, Rebecca K Green, David M Devilbiss, Craig W Berridge

Rowan-Virtua School of Osteopathic Medicine Faculty Scholarship

The PFC and extended frontostriatal circuitry support higher cognitive processes that guide goal-directed behavior. PFC-dependent cognitive dysfunction is a core feature of multiple psychiatric disorders. Unfortunately, a major limiting factor in the development of treatments for PFC cognitive dysfunction is our limited understanding of the neural mechanisms underlying PFC-dependent cognition. We recently demonstrated that activation of corticotropin-releasing factor (CRF) receptors in the caudal dorsomedial PFC (dmPFC) impairs higher cognitive function, as measured in a working memory task. Currently, there remains much unknown about CRF-dependent regulation of cognition, including the source of CRF for cognition-modulating receptors and the output pathways modulated …
