Neural Measures of Visual Attention and Suppression As Biomarkers for ADHD- Associated Inattention
Neural Measures of Visual Attention and Suppression as Biomarkers for ADHD- associated Inattention Rebecca Elizabeth Townley PhD University of York Psychology August 2019 Abstract Abstract Whilst there is a wealth of literature examining neural differences in those with ADHD, few have investigated visual-associated regions. Given extensive evidence demonstrating visual-attention deficits in ADHD, it is possible that inattention problems may be associated with functional abnormalities within the visual system. By measuring neural responses across the visual system during visual-attentional tasks, we aim to explore the relationship between visual processing and ADHD-associated Inattention in the typically developed population. We first explored whether differences in neural responses occurred within the superior colliculus (SC); an area linked to distractibility and attention. Here we found that Inattention traits positively correlated with SC activity, but only when distractors were presented in the right visual field (RVF) and not the left visual field (LVF). Our later work followed up on these findings to investigate separate responses towards task-relevant targets and irrelevant, peripheral distractors. Findings showed that those with High Inattention exhibited increased responses towards distractors compared to targets, while those with Low Inattention showed the opposite effect. Hemifield differences were also observed where those with High Inattention showed increased RVF distractor-related signals compared to those with Low Inattention. No differences were observed for the LVF. Finally, we examined attention and suppression-related neural responses. Our results indicated that, while attentional responses were similar between Inattention groups, those with High Inattention showed weaker suppression responses towards the unattended RVF. No differences were found when suppressing the LVF. -

These men are at substantial risk for neuropsychological impairment due to several factors, such as substance misuse, severe mental illness, untreated medical conditions (e.g., diabetes, liver disease, HIV/AIDS), poor nutrition, and the increased likelihood of suffering a traumatic brain injury. Impairments in attention, memory, executive functioning, and other neuropsychological domains can result in poor daily functioning and difficulty engaging in psychological, medical, or educational services. Thus, knowledge of the neuropsychological functioning of homeless men is critical for those who work with this population. Yet data in this area are limited. This study aimed to describe the functioning of men residing in an urban homeless shelter across the domains of attention/concentration, memory, executive functions, language, sensory-motor abilities, general intelligence, and reading ability. -

Addenbrooke's Cognitive Examination" As a Screening Test for Mild Cognitive Impairment in Hearing Impaired Individuals
Development and Validation of the “Addenbrooke’s Cognitive Examination” as a Screening Test for Mild Cognitive Impairment in Hearing Impaired Individuals Courtney North D.Clin.Psy. thesis (Volume 1), 2020 University College London 1 UCL Doctorate in Clinical Psychology Thesis declaration form I confirm that the work presented in this thesis is my own. Where information has been derived from other sources, I confirm that this has been indicated in the thesis. Signature: Name: Courtney North Date: 19th June 2020 2 Overview This thesis examined the utility of different neuropsychological tests in the detection of cognitive impairment in older adult populations. Limitations, directions for research and clinical implications have been highlighted. Part One: Meta-Analysis - The literature review sought to identify, for the first time, the cognitive tests that best discriminate between Posterior Cortical Atrophy (PCA) and typical Alzheimer’s Disease (tAD), as well as PCA and healthy controls (HC). The most discriminating cognitive tests for PCA and tAD presentations were found to be measures of perception and verbal memory. Part Two: Empirical Paper - The objectives were to develop a hearing-impaired version of the Addenbrooke’s Cognitive Examination (HI-ACE-III) and assess whether it can be used as a screening tool for mild cognitive impairment (MCI), as well as accurately distinguish cognitively impaired people from healthy controls. It was found to be a sensitive and specific screening tool, with a good ability to diagnose individuals with and without MCI in hearing-impaired populations. This was a joint project with Nattawan Utoomprurkporn, PhD student and qualified audiologist, and Mary Heatley, Trainee Clinical Psychologist Part Three: Critical Appraisal - The critical appraisal, considers the challenges of the project, including the barriers to recruitment, the navigation of the scientist- practitioner role and the impact of conducting research during a pandemic. -

This study was supported by the Yearly Doctorate Stipend of the DAAD (German Academic Exchange Service) over the whole time-period of two years that this study lasted. 2 DEDICATION This work is dedicated to all those sixty lovely patients participating in this study and the future patients that will hopefully benefit from our findings. I would like to express my gratitude to the DAAD (German Academic Exchange Service) for the awarded Yearly Doctorate Stipend helping me to realize my research project. 3 SUMMARY Cognitive symptoms are common in Parkinson disease (PD) and range from mild cognitive impairment (PD-MCI) to dementia (PDD). It is not fully understood, whether PD-MCI and PDD are consecutive events and evolve into each other or whether they display two different entities. The high conversion rate from PD-MCI to PDD points to a progressive pattern, while different cognitive profiles seems to be related with higher conversion risk to PDD. -
Communication Post Acquired Brain Injury
6. Interventions for Cognition and Cognitive- Communication Post Acquired Brain Injury Shawn Marshall MD MSc Penny Welch-West (M.CI.Sc. SLP) Connie Ferri (MSc. SLP) Pavlina Faltynek MSc Shannon Janzen MSc Leanne Togher PhD, Robert Teasell MD erabi.ca Version 13.0 Key Points Drill and practice training may not be effective for the remediation of attention following an ABI. Dual-task training has been shown to improve measures of attention to the extent that the ABI population does not significantly differ from healthy controls, however it is undetermined if the strength of these effects compared to non-dual-task training are greater. Computer-based interventions are no more effective than no intervention in improving measures of attention and concentration post ABI. Repetitive virtual reality tasks which include repetition are effective in improving attention and concentration in ABI populations. Goal management training is effective in assisting those who sustain an ABI learning to manage life goals through improved attention. In general, a variety of non-specific attentional training programs appear to be effective for improving attentional scores following an ABI. The addition of a therapy animal to an attentional training program may enhance concentration gains. Therapies which focus on emotional regulation do not appear to be effective at improving attention post ABI, while mindfulness may improve some areas. In order to determine if attentional training is effective in improving attention post-ABI standardized protocols must be developed to allow between study comparisons. Tasks that involve mathematical skills may be effective at improving attention post ABI. Transcranial direct current stimulation may be effective in remediating attentional deficits when combined with computer assisted training in ABI populations.
