Attention Deficit Hyperactivity Disorder Attention deficit hyperactivity disorder known as ADHD, it is a disorder that is found in children and can continue into adulthood.
Brain Imaging and Behavior; Apr The default mode network DMN is abnormal in a multitude of neurological and psychiatric disorders. Inclusion criteria were peacetime or wartime veterans regardless of branch of service and included those for whom the traumatic brain injury was not service related.
SPECT imaging was performed on this group both at rest and during a concentration task. These measures, as well as the baseline-concentration difference, were then inputted from DMN regions into separate binary logistic regression models controlling for age, gender, race, clinic site, co-morbid psychiatric diseases, TBI severity, whether or not the TBI was service related, and branch of armed service.
Predicted probabilities were then inputted into a receiver operating characteristic analysis to compute sensitivity, specificity, and accuracy. The purpose of this study was to conduct an investigation of brain areas related to anxiety using SPECT scans. Participants were administered a SPECT scan as part of a general evaluation for a wide variety of psychiatric disorders ranging from ADHD to schizophrenia and brain disorders.
They were grouped based on their responses to symptom questionnaires targeting anxiety symptoms specifically. Three groups were formed and were based on quartiles: Individuals in the moderate and high groups had significantly greater blood flow than the low group in the left cerebellum and caudate.
Individuals in the high group had significantly greater blood flow than the low group in the right cerebellum, and left and right olfactory bulbs. Individuals in the low group had greater blood flow than the high group in the left and right occipital lobe.
The results demonstrated that various areas of the brain, based on average amount of blood flow, differ based on varying levels of self-reported anxiety symptoms. No significant pattern of results emerged, which could demonstrate that blood flow in individuals with high levels of anxiety more global changes rather than specific to one area of the brain.
Future research should investigate more specifically the areas of the brain that differ between individuals to determine possible mechanisms by which they influence each other. Using a symptom checklist, participants Subjects in the upper quartile yielded significantly lower blood flow relative to the lower quartile in the following areas: The purpose of this study was to assess the differences of blood perfusion in those who scored in the upper compared to the lower quartiles of mania symptomology.
Analyses denoted significant differences in blood perfusion of those with a range of mania symptom severity.
Specifically, self-reported mania symptomology appears to be indicative of lower levels of blood perfusion in subcortical regions.
These results indicated that SPECT analysis could potentially be useful in the neurological aspect of research on mania symptomology. Ensuing research will aim to distinguish the relationship between brain areas and their associated specific symptoms.
Archives of Clinical Neuropsychology, 29 6: Data were collected from the self-reports of clients seen at the Amen Clinic. Participants included individuals with a self-reported diagnosis of an eating disorder, with an average age of The sample was mostly female, and subtypes of eating disorders were not identified.
Independent t-tests were used to analyze mean differences in blood flow between normals and eating disorders. No other areas of the brain revealed differences in blood flow while performing the CPT. Individuals with eating disorders showed more blood flow to the right inferior orbitofrontal cortex and cerebellum during the performance of the CPT.
Increased blood flow to the right inferior orbitofrontal cortex during the CPT may suggest that individuals with eating disorders may attend more to decision-making in relation to all visual stimuli, not just food and other body-related visual stimuli.
Increased blood flow to the cerebellum may suggest that individuals with eating disorders have increased motor control and attention.With 18 pieces interconnected, this twisty toy keeps your fingers good and busy Gifted children with Attention Deficit Hyperactivity Disorder (ADHD) (ERIC Digest #) by Maureen Neihart Are gifted children over-diagnosed with the disorder?
Attention Deficit Disorder Essay Words | 8 Pages. Attention Deficit Disorder Attention Deficit Disorder (ADD) is a problem that affects 5% to 10% of all children ADD affect more children than any other childhood problems except asthma. Attention Deficit Disorder, also known as ADD, ADHD, or simply hyperactivity, can be displayed among children, adolescents and even adults.
“Doctors and educators often use the term ‘attention-deficit disorder’ (ADD) to describe the way certain children act in the classroom” (NIMH “A Treatment Study”). Attention-Deficit Hyperactivity Disorder Attention-Deficit Hyperactivity Disorder (ADHD) is defined by intense inattention, hyperactivity, and impulsiveness in a srmvision.com with ADHD have many problems in academic settings.
Some of these problems are similar to the problems of people with learning disabilities: slow and inefficient reading, slow essay-writing, and frequent errors in math.
Attention Deficit Hyperactivity Disorder (ADHD) Essay Attention deficit hyperactivity disorder (ADHD) is a behavior problem that is characterized by hyperactivity, inattention, restlessness, and impulsivity and, until recently, was diagnosed primarily in children.
Abstract--To understand the relations between sibling interactions and the social adjustment of children with behavior problems, 53 aggressive 1st- and 2nd-grade children, their mothers, and their siblings were interviewed about positive and negative aspects of the sibling relationship.
