- Cognitive impairment in prostate cancer patients receiving androgen deprivation therapy: a scoping reviewPublication . Barreira, João Vasco; Barreira, Pedro; Falcão, Gil; Garcez, Daniela; Silva, Pedro; Santos, Gustavo; Fontes-Sousa, Mário; Mendes, José Leão; Reis, Filipa; Santos, Carla F.; Ribeiro, Filipa; Capelas, Manuel LuísBackground: Androgen deprivation therapy (ADT) is a primary treatment for prostate cancer (PCa) that effectively reduces androgen levels to suppress tumor progression. However, growing evidence suggests potential cognitive side effects, raising concerns about the long-term neurological consequences of this treatment. Objective: This scoping review aims to synthesize the existing evidence linking ADT to cognitive changes in men with PCa, identifying the key cognitive domains affected and outlining gaps in the existing literature. Methods: A systematic literature search was conducted according to the PRISMA-ScR guidelines in CINAHL, PubMed, Scopus, and Web of Science. Studies investigating cognitive function in ADT-treated PCa patients were included, covering randomized controlled trials (RCTs) and cohort, case–control, and cross-sectional studies. The extracted data included the study design, evaluated cognitive characteristics, measurement tools, and overall findings. Results: A total of 22 studies met the inclusion and exclusion criteria. Cognitive assessments varied across studies. While some studies reported cognitive impairments in ADT-treated patients—particularly in working, verbal, and visual memory and executive function—others found no significant effects. The variability in prostate cancer staging, epidemiological study designs, and treatment regimens; the exclusion of comorbid conditions; and the differences in assessment tools, sample sizes, and study durations hinder definitive conclusions about the cognitive effects of ADT. Conclusions: This scoping review highlights the heterogeneous and often contradictory evidence regarding ADT-associated cognitive dysfunction. While certain cognitive domains may be affected, methodological inconsistencies limit robust conclusions. Standardized cognitive assessments and longer longitudinal studies are required to clarify ADT’s role in cognitive decline. As the PCa survival rate increases with extended ADT use, integrating routine cognitive monitoring into clinical practice should be considered for PCa patients.
- Early numerical cognition in deaf and hearing children: closer than expected?Publication . Ribeiro, Filipa; Rato, Joana R.; Leonardo, Rita; Mineiro, AnaDeaf students show a significant delay in their understanding of numeracy and measurement concepts as well as verbal problem solving. There is still no consensus about the origin of this delay but several studies have shown that deaf people show differences in basic numerical skills and executive function (EF), which could underlie the differences in the way they learn and develop their cognitive abilities. Children have the innate ability to estimate and compare numerosities without using language or numerical symbols. The ability to discriminate large numerosities depends on the approximate number system (ANS), a cognitive system believed to be governed by a neural circuit within the intraparietal sulcus. Researchers hypothesize that the ANS underlies the development of arithmetic and there is data supporting the contribution of the ANS for math achievements. Little is known about the approximate number system of deaf children at early ages. Deaf and hearing preschool children were compared in terms of specific cognitive functions shown to be important for success in mathematics. Executive functions and symbolic and nonsymbolic magnitude comparison abilities of 7 deaf children and 14 hearing children aged 4–7 years (M = 69.90 months, SD = 11.42), were compared. To do so, neuropsychological assessments for school-aged children were adapted into Portuguese Sign Language. Significant group differences were found in abstract counting as well as in symbolic and nonsymbolic magnitude comparisons. These findings suggest that deaf children are less competent in these early numeracy skills than are their hearing peers.
- The efficacy of virtual reality-based EEG neurofeedback in health-related symptoms relief: a systematic reviewPublication . Castanho, Lina; Martinho, Diogo Vicente; Saial, Ana Cristina; Gouveia, Bruna Raquel; Gouveia, Élvio Rúbio; Ribeiro, FilipaEEG Neurofeedback is a noninvasive therapeutic modality that can potentially modify targeted aspects of brain function, considered promising for the treatment of neuropsychiatric disorders. Nevertheless, some limitations have considerable potential to compromise its efficacy, including the requirement for a high number of sessions, the repetition of therapeutic tasks, and the challenge in sustaining the objectives of these tasks. These limitations can induce a decline in system dynamism and user motivation. However, barriers can be overcome by integrating immersive virtual reality into a neurofeedback system to increase motivation, interest, and adherence through immersion and a sense of presence. This systematic review aimed to determine whether this combined treatment is effective in relieving symptoms related to general health. To conduct this search following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, six electronic databases were accessed on January 26, 2024. Inclusion and exclusion criteria were defined to select the articles, and risk of bias and methodological quality assessment was conducted using the Mixed Methods Appraisal Tool and the CRED-nf checklist. A total of 24 trials were included, and according to Template for Developing Guidelines for the Evaluation of the Clinical Efficacy of Psychophysiological Interventions, the results showed that it was considered a probably efficacious treatment for attention and a possibly efficacious treatment for emotions, mood, pain, relaxation, impulsiveness, memory, self-esteem, creativity, empathy, meditation, and tiredness. Several methodological factors of the trials restrict the generalization of these findings and require caution in their interpretation, despite the promising results in future directions.
- Evaluation of inhibitory control and attentional bias through eye-tracking: a modified emotional stop-signal taskPublication . Barros, Gonçalo; Ribeiro, FilipaObsessive-compulsive disorder (OCD) is characterized by deficits in inhibitory control and attentional processes. The emotional nature of stimuli can significantly influence these cognitive processes, yet traditional paradigms assessing inhibitory responses, such as the Stop-Signal Task, typically neglect emotional stimuli. This limitation reduces their capacity to capture the cognitive impairments associated with OCD fully. To address this gap, we introduce the Modified Emotional Stop-Signal Task (MESST), a novel paradigm designed to concurrently evaluate inhibitory control and attentional biases through eye-tracking technology. MESST integrates emotionally evocative stimuli into a standard stop-signal framework, allowing simultaneous measurement of Stop-Signal Reaction Time (SSRT) and attentional metrics such as latency to first fixation and total dwell time. Additionally, participants complete validated psychological scales—the State-Trait Anxiety Inventory (STAI), Barratt Impulsiveness Scale (BIS-11), and Obsessive-Compulsive Inventory–Revised (OCI-R)—providing detailed characterization of impulsivity and anxiety traits. Suitable for normative and clinical populations, MESST facilitates the investigation of interactions between emotional processing, cognitive control, and attentional biases, thereby advancing our understanding of the cognitive-emotional mechanisms underlying OCD and related disorders. • Integrates emotional stimuli into a standard inhibitory control paradigm. • Measures attentional processes concurrently via high-frequency eye-tracking. • Applicable to both clinical and non-clinical populations.
- Relação entre a área de formação e o desempenho na prova da Torre de HanóiPublication . Rocha, Ivo; Ribeiro, FilipaA Torre de Hanói é uma prova neuropsicológica, de funcionamento executivo, que fornece uma evidência clara da importância da criação de estruturas com objetivos e subobjetivos na resolução de problemas. Isto é, delinear mentalmente um trajeto entre o estado inicial e o final, permitindo antecipar eventos e as suas consequências, bem como monitorizar a proximidade ao objetivo final (Eysenck & Keane, 2007). Este trabalho tem como objetivo verificar o tempo e a capacidade de resolução da prova em dois cursos universitários distintos, Engenharia Eletrotécnica e Letras (Estudos Portugueses e Lusófonos). Parte -se do pressuposto de que o curso universitário influencia o modo como os alunos resolvem problemas, através da adaptação aos objetivos e matérias que são apreendidas durante a sua frequência. Colocou -se a hipótese de que os alunos do curso de engenharia resolveriam, em menos tempo e em menos jogadas, a prova, que os alunos de Letras. Os resultados corroboram a hipótese e demonstram assim maior capacidade de planeamento, utilização de pensamento estratégico, de resolução de problemas e flexibilidade cognitiva nos alunos de Engenharia Eletrotécnica.
- Relação entre linguagem e constituição psíquica em um caso de autismoPublication . Rodrigues, Rosa Vilela; Ribeiro, Filipa; Mineiro, AnaEsse trabalho trata-se de um estudo de caso de um menino de 2 anos e seis meses, com um diagnóstico psiquiátrico de Transtorno do Espectro Autista (TEA), atendido no Grupo de Avaliação e Prevenção de Alterações de Linguagem (GAPAL/FCM/UNICAMP) e justifica-se devido à importância da intervenção precoce em casos em que há indicadores de risco psíquico. A partir de uma fundamentação psicanalítica, pode-se considerar a posição autista como uma recusa à entrada na ordem da linguagem, o que gera uma série de impasses para a constituição psíquica do sujeito. O estudo teve por objetivos discutir os efeitos na linguagem do Transtorno do Espectro Autista (TEA) e analisar os recursos do manhês e da musicalidade como ferramentas na terapia fonoaudiológica. Conclui-se que o uso do manhês e da musicalidade, nos momentos fugazes de brincadeira compartilhada, foram estratégias terapêuticas importantes ao longo do atendimento fonoaudiológico.
- Sex differences in response inhibition in young childrenPublication . Ribeiro, Filipa; Cavaglia, Rita; Rato, Joana R.Competence in inhibiting prepotent responses has been frequently shown to be higher in females than in males in both children and adults. However, not all the inhibitory tasks seem equally sensitive to sex at each age. We investigated sex differences in two developmentally appropriate inhibitory tasks, the EYT Go/No-go and the Shape School Inhibition Condition. Our sample consisted of 160 preschool children, 85 boys and 75 girls, ranging from 4 to 6 years old. Girls’ efficacy in inhibiting prepotent motor responses in the Go/No-go task was higher than boys’, but not in the verbal Shape School inhibition task. Sex differences in inhibitory tasks are discussed in light of the different task requirements.
- Teleneuropsychology: reliability and acceptance in memory assessmentPublication . Varandas, Mariana; Ribeiro, FilipaIntroduction: The use of telehealth in psychological interventions has experienced a significant increase in recent years. This form of patient interaction has important implications, especially in neuropsychological assessment. Given the limited research on this subject in Portugal, the reliability of neuropsychological tests and acceptance of this format by the Portuguese elderly must be studied. Methods: The sample consisted of 43 healthy Portuguese adults. They were assessed by cognitive measures and questionnaires regarding sociodemographic aspects, memory complaints, computer literacy, functionality, depressive symptoms, and satisfaction with the teleconsultation via videoconference and in-person approaches. The order of the two conditions was randomized. Results: There were no significant differences between scores on the Logical Memory Test. However, higher scores were found in the online condition for the Paired Associate Learning Test. The level of satisfaction with teleconsultation was high, but it did not translate into a greater preference for this format. Discussion: The neuropsychological assessment of auditory-verbal episodic memory through teleconsultation is promising and well accepted by the older Portuguese population. The data indicate that teleconsultation provides reliable results for episodic memory assessment.

- Validação clínica da versão portuguesa do questionário de hábitos de sono das crianças (CSHQ-PT) em crianças com perturbações do sono e PHDAPublication . Parreira, Ana Filipa; Martins, António; Ribeiro, Filipa; Silva, Filipe GlóriaIntrodução: A versão Portuguesa do Children’s Sleep Habits Questionnaire mostrou propriedades psicométricas adequadas numa amostra comunitária mas o ponto de corte americano pareceu desadequado. O objetivo deste estudo foi validar este questionário em populações clínicas de crianças com distúrbios do sono e com perturbação de hiperatividade/ défice de atenção. Material e Métodos: Participaram no estudo 148 crianças Portuguesas com idades entre os 2 e os 10 anos, divididas em três grupos: 1. Grupo clínico com perturbação do sono (insónia comportamental, parassónias ou perturbação respiratória do sono); 2. Grupo clínico com perturbação de hiperatividade/ défice de atenção; 3. Grupo controlo. Os hábitos e problemas do sono foram avaliados através do Children’s Sleep Habits Questionnaire. A perturbação respiratória do sono foi confirmada por polissonografia. Resultados: A coerência interna do questionário (α de Cronbach) na amostra clínica (perturbações do sono e perturbação de hiperatividade/ défice de atenção) foi de 0,75 e variou de 0,55 a 0,85 nas subescalas. As crianças com perturbações do sono e com perturbação de hiperatividade/ défice de atenção apresentaram um índice de perturbação do sono mais elevado do que o grupo controlo. As subescalas apresentaram diferenças significativas nos subgrupos de perturbações do sono revelando validade discriminante. A análise receiver operating characteristic do índice de perturbação do sono do grupo com perturbação do sono versus grupo controlo determinou um ponto de corte de 48. Discussão: As crianças com perturbações do sono e com perturbação de hiperatividade/ défice de atenção apresentaram um Índice de Perturbação do Sono mais elevado do que o grupo controlo. As subescalas apresentaram diferenças significativas nos subgrupos de perturbações do sono revelando validade discriminante. Conclusão: A versão Portuguesa do Children’s Sleep Habits Questionnaire mostrou propriedades psicométricas adequadas em crianças com perturbações do sono e/ou perturbação de hiperatividade/ défice de atenção. O ponto de corte de 48 é mais adequado para a população Portuguesa.
