Effects Of Atomoxetine On Circadian Rhythms And Locomotor Activity, Rhiannon Ryder Crimmins
Cal Poly Humboldt theses and projects
Background: Attention deficit hyperactivity disorder (ADHD) is a common neurological disorder characterized by inattention, hyperactivity, and impulsive behavior. Many people with ADHD who are taking pharmacological treatments also report having sleep problems, and both children and adults tend to fall asleep later than neurotypical people. Since diagnosis and treatment of ADHD are on the rise, understanding how the disorder and common medications influence circadian rhythms is becoming more important. Zebrafish are a common animal model that have been shown to reliably represent features of many human disorders, including ADHD. Hypothesis: The specific hypotheses tested were: (H1) that a …
Event-Related Potentials Of Individuals With Attention-Deficit/Hyperactivity Disorder Performing The Attention Network Task, P. Dennis Rodriguez, Justin E. Stauffacher
Event-Related Potentials Of Individuals With Attention-Deficit/Hyperactivity Disorder Performing The Attention Network Task, P. Dennis Rodriguez, Justin E. Stauffacher
Midwest Social Sciences Journal
The current study sought to investigate the neural basis of attention-deficit/hyperactivity disorder (ADHD) by examining the performance of individuals with ADHD on the Attentional Networks Test (ANT) by Fan, McCandliss, Sommer, Raz, and Posner (2002), while recording electroencephalography (EEG) utilizing event-related potentials (ERP) methodology. Fifty-seven university students were divided into three groups: control, ADHD-inattentive subtype (ADHD-IA), and ADHD-combined/hyperactive impulsive subtype (ADHD-C/HI). The average peak amplitudes of the P300 waveform for each group were compared and analyzed for performance on each attention network measured by the ANT: the alerting network, the orienting network, and the executive control network. The average P3 …
Medication Versus Brain-Based Treatment: Evaluation Treatment Preferences Of Parents Of Children With Adhd, Rebecca Recio-Swift
Medication Versus Brain-Based Treatment: Evaluation Treatment Preferences Of Parents Of Children With Adhd, Rebecca Recio-Swift
Electronic Theses and Dissertations
Attention-Deficit/Hyperactivity Disorder (ADHD) is one of the most prevalent neurodevelopmental disorders across the world. Currently, treatment for ADHD mostly consists of either medication or behavioral therapy or a combination of both. However, research has shown that medication used as therapy for the treatment of ADHD has side effects which parents deem undesirable for their children. Therefore, recent research has focused on patient and parent preferences. Studies have found that behavioral or other treatment options may often be chosen over medications. These same studies have documented the characteristics of parents that prefer certain treatments for their children. The purpose of this …
Effects Of Neonatal Ethanol Exposure In Normal And Dopamine Deficient Rats, Jessica Luz Razo
Effects Of Neonatal Ethanol Exposure In Normal And Dopamine Deficient Rats, Jessica Luz Razo
Electronic Theses, Projects, and Dissertations
Attention deficit hyperactivity disorder (ADHD) is a common developmental disorder characterized by impulsivity, inattention, and hyperactivity. In rodents, neonatal 6-OHDA lesions is an established model of ADHD because it produces symptoms of hyperactivity and cognitive deficits that improve following psychostimulant treatment. Recently, early alcohol exposure in rodents has also been suggested as a model of ADHD due to the high prevalence of ADHD in children exposed prenatally to alcohol. However, children exposed to prenatal alcohol differ in symptoms from children with idiopathic ADHD, suggesting that ADHD caused by prenatal alcohol exposure may be a special subtype of ADHD or a …

Development Of Prefrontal Structure And Connectivity In Typical Children And Children With Adhd: Association With Language And Executive Function, Dea Garic
FIU Electronic Theses and Dissertations
The structure and connectivity of the prefrontal cortex has been extensively studied for its contribution to language and executive function (EF) development, but many questions still remain whether its microstructural tissue properties can reliably predict behavioral outcomes in very young typically and atypically developing populations. In particular, the bilateral frontal aslant tract (FAT) has garnered increasing interest with respect to its potential association with both language and EF, but has yet to be examined in childhood attention disorders, such Attention Deficit Hyperactivity Disorder (ADHD). At the same time, with advances in diffusion weighted imaging (DWI), new diffusion models offer more …

Treating Adhd With Suggestion: Neurofeedback And Placebo Therapeutics, Robert T. Thibault, Samuel Vassière, Jay A. Olson, Amir Raz
Psychology Faculty Articles and Research
Objective: We propose that clinicians can use suggestion to help treat conditions such as ADHD. Methods: We use EEG neurofeedback as a case study, alongside evidence from a recent pilot experiment utilizing a sham MRI scanner to highlight the therapeutic potential of suggestion-based treatments. Results: The medical literature demonstrates that many practitioners already prescribe treatments that hardly outperform placebo comparators. Moreover, the sham MRI experiment showed that, even with full disclosure of the procedure, suggestion alone can reduce the symptomatology of ADHD. Conclusion: Non-deceptive suggestion-based treatments, especially those drawing on accessories from neuroscience, may offer a safe complement and potential …
The Neural Correlates Of Emotion Reactivity And Regulation In Young Children With Adhd, Claudia I. Lugo-Candelas
The Neural Correlates Of Emotion Reactivity And Regulation In Young Children With Adhd, Claudia I. Lugo-Candelas
Doctoral Dissertations
Attention-deficit hyperactivity disorder (ADHD) is the most frequently occurring pediatric neurobehavioral disorder. Although emotion reactivity and regulation are frequently impaired in ADHD, few studies have examined these factors in preschool aged children with ADHD, and none have explored the neural correlates of emotion reactivity and regulation in this group though event-related potentials (ERPs). Children aged 4 to 7 with (n = 24) and without (n = 30) ADHD symptoms completed an attention task composed of four blocks: baseline, frustration, suppression, and recovery. In the frustration and suppression blocks, negative affect was induced by false negative feedback. During the …
Behavioral And Neuroanatomical Outcomes Of Early And Late Preterm Hypoxic-Ischemic Injury And The Neuroprotective Effects Of Whole-Body Hypothermia: An Animal Model, Haley C. Garbus
University Scholar Projects
The overarching aims of this research were: first, to characterize the anatomical and behavioral effects of preterm hypoxic-ischemic (HI) injury in rodent models; and second, to explore the method of passively induced whole-body hypothermia as a neuroprotective intervention following HI. Clinical research of preterm injured infants has shown a large range of behavioral deficits, including delays in language learning, spatial and non-spatial memory, visual attention, and motor coordination. The current studies focused on these behavioral abnormalities, using HI rodent models. Specifically, we explored a model for early preterm HI (HI induced on postnatal day (P) 3 in rats), and compared …
The Impact Of An Omega-3 Enriched Diet On Hyperactivity And Biochemistry In An Animal Model For Attention-Deficit/Hyperactivity Disorder, Nadine M. Hammoud
The Impact Of An Omega-3 Enriched Diet On Hyperactivity And Biochemistry In An Animal Model For Attention-Deficit/Hyperactivity Disorder, Nadine M. Hammoud
Open Access Theses
Attention-deficit/hyperactivity disorder (ADHD) is the most diagnosed behavioral disorder in children. It affects around 5% of children worldwide and 11% of children in the United States, with rates increasing. Pharmaceutical treatments, such as amphetamines and methylphenidates, are not effective for everyone and are known to have unwanted side effects. While the etiology of the disorder is not yet fully understood, there are clear genetic and environmental components. Nutritional insufficiencies have recently become a popular environmental risk factor under investigation. Essential fatty acids (EFA), omega-3 polyunsaturated fatty acids (PUFA) in particular, are needed for proper brain development and function. Our lab …

Subjects were 63 unmedicated children aged 6 to 16 who had been assessed with the Wechsler Intelligence Scale for Children–Fourth Edition (WISC–IV), Conners’ Continuous Performance Test-Second Edition (CPT–II), and the Child Behavior Checklist (CBCL). Group differences were found for the WISC–IV Digits Backward subtest (IA + INT IA and IA + INT), and externalizing behavior scales on the CBCL and TRF …
Effects Of Early Developmental Stress On Adult Physiology And Behavior, Michael James Frederick
Effects Of Early Developmental Stress On Adult Physiology And Behavior, Michael James Frederick
Legacy Theses & Dissertations (2009 - 2024)
Events during early development can have long-term effects on physiology and behavior. While extreme developmental stress is known to be associated with a variety of behavioral problems, it is less well understood how milder stress may affect behavior, personality, and reproductive success. This research project assessed a variety of behavioral dimensions in a college age sample, while assessing early development using size at birth, fluctuating asymmetry, and retrospective surveys. Maternal stress during pregnancy was found to reduce adolescent growth spurts and adult handgrip strength in the offspring. In males, lower birth weights were associated with higher scores of impulsivity and …

Comparisons Among Parent Reports And Self-Reports Of Sleep In Adhd And Normal School-Aged Children, Diana M. Turner-Eadie
Psychology Theses & Dissertations
The objective of the study was to investigate whether school-aged children diagnosed with Attention-Deficit Hyperactivity Disorder (ADHD) experience greater sleep disturbance than do normally-developing children. Participants included 33 parents and their children with ADHD (mean age = 10.7 ± 1.7 years) and 33 parents and their children without ADHD (mean age = 10.7 ± 1.6 years). Both parents and their children completed sleep questionnaires developed to assess a number of sleep variables. Based on parental report, the Total Sleep Disturbance score was significantly greater for the ADHD group than for the comparison group. Parents indicated that children with ADHD had …
