Abstract(s)
Durante uma cirurgia acordado ao cérebro, as diversas funções cognitivas são monitorizadas através
de testes neuropsicólogicos durante estimulações elétricas. O domínio da linguagem é o domínio
mais testado neste tipo de cirurgia. Avaliar outras funções cognitivas durante este procedimento,
apresentam inúmeras limitações, tais como, a criação e validação de tarefas tendo em conta as
condições disponibilizadas durante a cirurgia. A realidade virtual permite a combinação de real ismo com o controlo experimental necessário durante a avaliação cognitiva, o que consequentemente,
permite inúmeras possibilidades de avaliar outras funções cognitivas mais complexas, tais como a
cognição social. Caso a cognição social não seja avaliada corretamente, isto pode causar que a
pessoa afetada apresente muitas dificuldade em manter e criar relações sociais, assim como afetar
significativamente a sua capacidade de compreensão de interações sociais ou comportamentos inde vidos em sociedade. Com esta pesquisa, adaptámos um instrumento de avaliação neuropsicológica
da cognição social - o Edinburgh Social Cognition Test (ESCoT) - para a realidade virtual (VR),
que denominámos CogMap para Cognição Social (CogMap-CS). Três estudos, com dois protótipos
diferentes do CogMap-CS (interação com comandos físicos e rastreamento ocular) foram realiza dos com participantes saudáveis e pacientes que apresentavam lesões cerebrais ou crescimento de
tumores cerebrais. Em geral, o CogMap-CS apresentou pontuações e feedback muito positivos, per mitindo a recolha de mais informações sobre como podemos proceder para atingir o nosso objetivo
final de validação clínica. No futuro, pretendemos implementar o CogMap-CS para ser utilizado
durante cirurgias com paciente acordado ao cérebro e obter validação de profissionais de saúde e
psicólogos na área de neuropsicologia.
During Awake Brain Surgery (ABS), cognitive functions are monitored with neuropsychological tests during electrical stimulation. Language is the most tested domain. Assessing other higher cognitive functions imposes limitations primarily due to the challenges associated with tailoring neuropsychological tasks to the conditions of awake surgery. Virtual Reality (VR) can combine the realism of stimuli with the experimental control required during cognitive evaluation, offering possibilities of assessing other complex cognitive functions, such as the case of social cognition. If not assessed properly, this can cause the affected person to suffer from severe social detachment, hindering their ability to understand social interactions or social signals. Within this research, we have adapted a neuropsychological assessment instrument of social cognition - the Edinburgh Social Cognition Test (ESCoT) - to virtual reality (VR), which we have named CogMap for Social Cognition (CogMap-SC). Three studies, with two different prototypes of CogMap-SC (virtual re ality controllers and eye-tracking) were conducted with healthy participants and traumatic brain injury/tumor patients. Overall, CogMap-SC presented very positive scores and feedback giving us more insight on how we can proceed to achieve our final goal of clinical validation. In the future, we intend to implement this VR application for use during an ABS and obtain validation from health professionals and psychologists.
