Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) viral infection is notable for a high degree of symptom diversity. Emerging evidence suggests viral invasion of the central nervous system; therefore, serious neurological and psychiatric manifestations are anticipated. We present the case of a 67-year-old male physician with a history of stable Bipolar Disorder for decades, hospitalized for persistent COVID-19 symptoms with documented positive serology, who presented with new and acute onset neuropsychiatric symptoms of disinhibition proximate the viral infection. We postulate neuroinvasion as the putative origin of the patient’s psychiatric instability. Further investigation is needed to expand upon our understanding of the …

Frontotemporal dementia (FTD), otherwise known as Pick’s disease, is a clinically heterogeneous group of sporadic and familial neurodegenerative diseases. These conditions are characterized by dementia, behavioural and language dysfunction and loss of executive skills resulting from the degeneration of the frontal and temporal lobes. Although reversible causes of dementia are always sought during the evaluation of patients with progressive cognitive decline, the occurrence of a reversible aetiology may distract from evaluating for neurodegenerative causes of dementia. This report is about a 66-year old man with features of FTD and superimposed chronic subdural haematoma.
Effects Of Multisensory Stop Signals On Sensitivity To Alcohol-Induced Disinhibition In Drinkers With Adhd, Alexandra R. D'Agostino
Effects Of Multisensory Stop Signals On Sensitivity To Alcohol-Induced Disinhibition In Drinkers With Adhd, Alexandra R. D'Agostino
Theses and Dissertations--Psychology
Multisensory environments facilitate behavioral functioning in humans. The redundant signal effect (RSE) refers to the observation that individuals respond more quickly to stimuli when information is presented as multisensory, redundant stimuli rather than as a single stimulus presented to either modality alone. Our studies show that the disinhibiting effects of alcohol are attenuated when stop signals are multisensory versus unisensory. The present study expanded on this research to test the degree to which multisensory stop signals could also attenuate the disinhibiting effects of alcohol in those with attention-deficit hyperactivity disorder (ADHD), a clinical population characterized by poor impulse control. The …
The Effects Of Ketamine And Other Rapid Antidepressants On Hippocampal Circuits, Allie J. Widman
The Effects Of Ketamine And Other Rapid Antidepressants On Hippocampal Circuits, Allie J. Widman
All ETDs from UAB
Major Depressive Disorder (MDD) in a common mental disorder that can impair cognitive functioning and negatively impact hippocampus. While several pharmacological treatments are currently available for MDD, most target the monoamine system, providing little variety in approaching treatment. Additionally, a large percentage of people with MDD have an inadequate response to this drug class, leaving them with little optimism of a full functional recovery. Recently, low-dose ketamine, an open-channel N-methyl D-aspartate receptor (NMDAR) antagonist, produced rapid antidepressant effects in humans, including people who do not respond to monoamine-based therapies, that lasted for days. The antidepressant-like behavioral effect of ketamine is …
Acetylcholine Release In Mouse Hippocampal Ca1 Preferentially Activates Inhibitory-Selective Interneurons Via Α4Β2* Nicotinic Receptor Activation, L. Andrew Bell, Karen A. Bell, A. Rory Mcquiston
Acetylcholine Release In Mouse Hippocampal Ca1 Preferentially Activates Inhibitory-Selective Interneurons Via Α4Β2* Nicotinic Receptor Activation, L. Andrew Bell, Karen A. Bell, A. Rory Mcquiston
Anatomy and Neurobiology Publications
Acetylcholine (ACh) release onto nicotinic receptors directly activates subsets of inhibitory interneurons in hippocampal CA1. However, the specific interneurons activated and their effect on the hippocampal network is not completely understood. Therefore, we investigated subsets of hippocampal CA1 interneurons that respond to ACh release through the activation of nicotinic receptors and the potential downstream effects this may have on hippocampal CA1 network function. ACh was optogenetically released in mouse hippocampal slices by expressing the excitatory optogenetic protein oChIEF-tdTomato in medial septum/diagonal band of Broca cholinergic neurons using Cre recombinase-dependent adeno-associated viral mediated transfection. The actions of optogenetically released ACh were …

Impulsivity And Cigarette Craving: Differences Across Subtypes, Neal Doran, Jessica Werth Cook, Dennis E. Mcchargue, Bonnie Spring
Impulsivity And Cigarette Craving: Differences Across Subtypes, Neal Doran, Jessica Werth Cook, Dennis E. Mcchargue, Bonnie Spring
Department of Psychology: Faculty Publications
Rationale: Cigarette smoking has been linked to a number of personality characteristics, including impulsivity. Smokers tend to endorse high levels of impulsivity, and more impulsive smokers have greater difficulty quitting, but little is known about potential explanatory mechanisms. Although indirect evidence suggests craving as a candidate mechanism, direct evidence has been mixed.
Materials and methods: This study assessed whether specific aspects of impulsivity (sensation seeking, lack of premeditation, lack of perseverance, and urgency) were associated with cue-induced craving. Regular smokers (n= 60; 50% female) were exposed to a smoking cue and a neutral cue in a repeated measure …
