Social participation following right hemisphere stroke: influence of a cognitive-communication disorder

Abstract

Dr Petrea Cornwell, as my primary PhD supervisor, your guidance and support has been invaluable. Thank you for sharing this research journey and my passion for the research topic. Thank you also to Professor David Shum, as my co-supervisor, your positive attitude and trust in my ability to complete the research was greatly appreciated. The combination of both Speech Pathology and Applied Psychology expertise that you generously shared has been extremely valuable. I would like to acknowledge the important contribution that all of the research participants made to this research-thank you for your time and for entrusting me with your personal stories of life changing events. Finally, thank you to my family, my work colleagues, and HDR peers for your encouragement and support throughout this process.

Acute single channel EEG predictors of cognitive function after stroke

“…However, participants were not monitored over the time between EEG recordings and cognitive testing. While none of the participants received any form of cognitive remediation from their treating inpatient team, the impact of physical rehabilitation [ 68 – 70 ] or other factors such as the quality of social relationships [ 71 – 73 ] or outpatient care [ 72 ] may have influenced cognitive outcomes. Furthermore, seemingly objective instruments such as the MoCA can require some degree of subjectivity, and the methodology in future studies is recommended to include blinding of outcome assessors to reduce the risk of ascertainment bias.…”

Proposta de apresentação da classificação dos transtornos de linguagem oral no adulto e no idoso

“…Eles podem ocorrer em decorrência de qualquer condição neurológica e até psiquiátrica, e são comuns em quadros de demência, prejuízo cognitivo leve, AVE, tumores cerebrais e TCE. [25][26][27] Para clarificar o conceito de transtorno cognitivo da comunicação, é possível tomar como exemplos os déficits nos seguintes domínios cognitivos e suas possíveis consequências na comunicação: memória episódica -o indivíduo não lembra que já fez determinada pergunta ou afirmação e repete-a constantemente, interferindo na efetividade da sua comunicação; atenção -quando o indivíduo não consegue manter a atenção na conversação, ocorre a perda de informação, podendo prejudicar a compreensão da mensagem. Neste caso, o déficit não é na função de compreensão oral, mas sim na atenção, o que pode ser facilmente confundido; controle inibitório -pode ter como consequência na comunicação dificuldades em respeitar os turnos de Há a ocorrência de apraxia de fala e agramatismo, que podem aparecer de forma isolada ou em conjunto.…”

Understanding Others Requires Right Temporoparietal and Inferior Frontal Regions

“…Inappropriately responding during conversation to misunderstandings of what a speaker knows and intends creates increasingly poor social interactions and relationships [13][14][15] . Distressingly, communication deficits have profoundly damaging effects on quality of life by decreasing return to work, social participation, and interpersonal relationships 5,[16][17][18][19][20][21][22][23] which result in increased morbidity and mortality 24,25 . Thus, uncovering the behavioral and neural mechanisms underlying right hemisphere (RH) deficits will help understand their impact on quality of life with the goal of developing better methods for assessment and intervention thus improving access to health care and long-term outcomes for this underserved patient population 5,26,27 .…”
