Not exact matches

Physical punishment is associated with a range of mental health problems in children, youth and adults, including depression, unhappiness, anxiety, feelings of hopelessness, use of drugs and alcohol, and general psychological maladjustment.26 — 29 These relationships may be mediated by disruptions in parent — child attachment resulting from pain inflicted by a caregiver, 30,31 by increased levels of cortisol32 or by chemical disruption of the brain's mechanism for regulating stress.33 Researchers are also finding that physical punishment is linked to slower cognitive development and adversely affects academic achievement.34 These findings come from large longitudinal studies that control for a wide range of potential confounders.35 Intriguing results are now emerging from neuroimaging studies, which suggest that physical punishment may reduce the volume of the brain's grey matter in areas associated with performance on the Wechsler Adult Intelligence Scale, third edition (WAIS - III).36 In addition, physical punishment can cause alterations in the dopaminergic regions associated with vulnerability to the abuse of drugs and alcohol.37

Even more important, this seminal work opens the road for comparative neuroimaging studies in which humans and other animals perform similar tasks using similar methodologies, and the results can be analyzed using similar strategies.

In addition to suggesting that creatine could slow the progression of HD, these results also imply that neuroimaging may provide a useful biomarker of disease modification in studies of other potential treatments.

Dr. Prescott and colleagues analyzed results from 102 patients enrolled in a national study called the Alzheimer's Disease Neuroimaging Initiative (ADNI) 2.

Lucina Uddin, Ph.D., assistant professor in the Department of Psychology at the University of Miami, who was not part of the research team, said, «The combination of multiple neuroimaging modalities is a clear strength of the current study, and the authors are to be commended for undertaking the difficult task of trying to reconcile results from methods designed to tap different aspects of brain structure and function.

REVEAL - SCAN: Risk Evaluation and and Education of Alzheimer's Disease - the Study of Communicating Amyloid Neuroimaging (RF1 AG047866) is the first multi-site, randomized clinical trial to examine the impact of learning amyloid imaging results in cognitively normal individuals, and its goal is to answer these questions.

Interpret the results of neuroimaging studies such as Magnetic Resonance Imaging (MRI), Single Photon Emission Computed Tomography (SPECT), and Positron Emission Tomography (PET) scans.

While functional neuroimaging studies illustrate the areas of the brain active when completing particular tasks, it is not always true that different brain functioning results in different behaviour.

These findings extend the substantial body of behavioral data demonstrating the deleterious effects of poverty on child developmental outcomes into the neurodevelopmental domain and are consistent with prior results.8, 9 Furthermore, these study findings extend the available structural neuroimaging data in children exposed to poverty by informing the mechanism of the effects of poverty on hippocampal volumes.

Studies were included in our meta - analyses if the following criteria were given: (I) included at least one clinical group with described aggressive behaviour, (II) in combination with a healthy control sample, (III) conducted during adolescence, (IV) reported whole brain gray matter volume alterations or whole brain functional neuroimaging data, (V) results are described using a standard reference space (Talairach or MNI) and (VI) the same threshold was used throughout the whole brain analysis.

Furthermore, neuroimaging studies investigating the neural correlates that underlie emotional processing deficits characteristic for youth with ODD problems, such as poor fear conditioning and impaired processing of emotional faces (Glenn and Raine, 2008; Hyde et al., 2013; Blair et al., 2014; Baker et al., 2015), have suggested divergent results.

Given their typical age of onset, a broad range of mental disorders are increasingly being understood as the result of aberrations of developmental processes that normally occur in the adolescent brain.4 — 6 Executive functioning, and its neurobiological substrate, the prefrontal cortex, matures during adolescence.5 The relatively late maturation of executive functioning is adaptive in most cases, underpinning characteristic adolescent behaviours such as social interaction, risk taking and sensation seeking which promote successful adult development and independence.6 However, in some cases it appears that the delayed maturation of prefrontal regulatory regions leads to the development of mental illness, with neurobiological studies indicating a broad deficit in executive functioning which precedes and underpins a range of psychopathology.7 A recent meta - analysis of neuroimaging studies focusing on a range of psychotic and non-psychotic mental illnesses found that grey matter loss in the dorsal anterior cingulate, and left and right insula, was common across diagnoses.8 In a healthy sample, this study also demonstrated that lower grey matter in these regions was found to be associated with deficits in executive functioning performance.

Our results are in line with other neuroimaging studies that have found reduced activations to different kinds of affective stimuli within the brain emotional systems in violent adult subjects and in adolescents with conduct disorder.
