Self-Harm In Female Youth With Undiagnosed Adhd: Implementing American Academy Of Pediatrics Screening Guidelines, Roselie M. Woodard

Dissertations

Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder characterized by inattention, hyperactivity, and impulsivity. If undiagnosed or untreated, ADHD can lead to severe psychosocial issues such as academic failure, substance abuse, unplanned pregnancy, and incarceration. The financial burden in the U.S. from diagnostic errors creates an immense, rising fiscal impact. Early diagnosis and management are crucial to prevent these complications.

Females with ADHD, particularly those with the inattentive subtype, often face diagnostic challenges due to symptom masking and over-compensation. This results in poorer cognitive functioning and self-esteem compared to males with ADHD. ADHD is linked to autonomic nervous …

The Evolving Use Of Gold Nanoparticles As A Possible Reversal Agent For The Symptoms Of Neurodegenerative Diseases: A Narrative Review, Alan D. Kaye, Kelly R. Sala, Drew Dethloff, Matthew Norton, Corey Moss, Michael J. Plessala, Alyssa G. Derouen, Yair Lopez Torres, Julian Kim, Sridhar Tirumala, Sahar Shekoohi, Giustino Varrassi

School of Medicine Faculty Publications

Neurodegenerative diseases are broadly hallmarked by impaired energy metabolism and toxic intracellular accumulations such as damaged organelles or reactive oxygen species (ROS). Gold nanoparticles readily cross the blood-brain barrier and increase nicotinamide adenine dinucleotide + hydrogen (NADH) oxidation to nicotinamide adenine dinucleotide (NAD+), which is vital for intracellular energy generation, cellular repair, and protection from ROS. Thus, the use of gold nanoparticles to treat and potentially reverse cellular injury seen in neurodegenerative disease has been an area of ongoing research. This systematic review explores current literature regarding the use of gold nanoparticle therapy in the treatment of neurodegenerative diseases such …

Pituitary Adenoma Presenting As Cranial Nerve Iii Palsy And Hemifacial Pain, Yoona Choe, Justin George, Matthew Boyle, Peter Maduka

Rowan-Virtua Research Day

Pituitary adenomas are common neoplasms arising from the pituitary adenohypophyseal cell. They can be classified by cell type, size and as nonfunctioning or functioning based on the secretion of pituitary hormones. Of these, approximately 48% are macroadenomas (>10 mm) and approximately 53% are prolactinomas. For how common these adenomas are, only 1 of 1100 persons manifest clinical symptoms¹ rendering detection and clinical management challenging.

Non-functioning adenomas are slow growing like most pituitary adenomas and are usually detected due to their mass effect on neighboring structures.² The majority of the reported symptoms as a results of these mass …

Exploring The Neuroprotective Effects Of Cannabinoids On Oxygen Glucose Deprived Neurons In An In-Vitro Model Of Stroke, Bhavya Chatragadda, Emily Potts, Hang Ma, Navindra Seeram, Claudia Fallini

Senior Honors Projects

Stroke is a leading cause of long-term disability and decreased mobility worldwide. During stroke, neuronal damage results from both the initial oxygen-glucose deprivation and the increase in excitotoxicity and oxidative stress after restoration of blood flow, a phase called Ischemia-Reperfusion Injury (IRI). Reducing the impact of these processes could result in better outcomes for post-stroke patients by preventing excessive neuronal death. Many natural compounds derived from the Cannabis Sativa plant have been tested for neuroprotective effects due to their potential antioxidant properties. We hypothesized that neurons treated with cannabinoids immediately after experiencing an acute ischemic event will have an overall …
