Publication Biomarkers for dementia in Latin American countries: Gaps andopportunities(2023) Parra, Mario A.; Orellana, Paulina; León, Tomas; Victoria, Cabello G.; Henriquez, Fernando; Gomez, Rodrigo; Avalos, Constanza; Damian, Andres; Slachevsky Chonchol, Andrea; Ibañez, Agustin; Zetterberg, Henrik; Tijms, Betty M.; Yokoyama, Jennifer S.; Piña-Escudero, Stefanie D.; Cochran, Nicholas; Matallana, Diana L.; Acosta, Daisy; Allegri, Ricardo; Arias-Suáres, Bianca P.; Barra, Bernardo; Behrens, María Isabel; Brucki, Sonia M.D.; Busatto, Geraldo; Caramelli, Paulo; Castro-Suarez, Sheila; Contreras, Valeria; Custodio, Nilton; Dansilio, Sergio; De la Cruz-Puebla, Myriam; Cruz de Souza, Leonado; Díaz, Monica M.; Duque, Lissette; Farias, Gonzalo A.; Ferreira, Sergio T.; Magrath Guimet, Nahuel; Kmaid, Ana; Lira, David; Lopera, Francisco; Mar Meza, Beatriz; Miotto, Eliane C.Limited knowledge on dementia biomarkers in Latin American and Caribbean (LAC)countries remains a serious barrier. Here, we reported a survey to explore the ongo-ing work, needs, interests, potential barriers, and opportunities for future studiesrelated to biomarkers. The results show that neuroimaging is the most used biomarker(73%), followed by genetic studies (40%), peripheral fluids biomarkers (31%), and cere-brospinal fluid biomarkers (29%). Regarding barriers in LAC, lack of funding appears toundermine the implementation of biomarkers in clinical or research settings, followedby insufficient infrastructure and training. The survey revealed that despite the abovebarriers, the region holds a great potential to advance dementia biomarkers research.Considering the unique contributions that LAC could make to this growing field,we highlight the urgent need to expand biomarker research. These insights allowedus to propose an action plan that addresses the recommendations for a biomarkerframework recently proposed by regional experts.Publication Does culture shape our understanding of others' thoughts and emotions? An investigation across 12 countries(2022) Quesque, François; Coutrot, Antoine; Cox, Sharon; Cruz de Souza, Leonardo; Baez, Sandra; Cardona, Juan; Mulet, Hannah; Flanagan, Emma; Neely, Alejandra; Clarens, María; Cassimiro, Luciana; Musa, Gada; Kemp, Jennifer; Botzung, Anne; Philippi, Nathalie; Cosseddu, Maura; Trujillo, Catalina; Grisales, Johan; Fittipaldi, Sol; Magrath, Nahuel; Calandri, Ismael; Crivelli, Lucia; Sedeno, Lucas; Sedeno, Lucas; Garcia, Adolfo; Moreno, Fermin; Indakoetxea, Begoña; Benussi, Alberto; Brandão, Millena; Santamaria, Hernando; Matallana, Diana; Pryanishnikova, Galina; Morozova, Anna; Iakovleva, Olga; Veryugina, Nadezda; Levin, Oleg; Zhao, Lina; Liang, Junhua; Duning, Thomas; Lebouvier, Thibaud; Pasquier, Florence; Huepe, David; Barandiaran, Myriam; Johnen, Andreas; Lyashenko, Elena; Allegri, Ricardo; Borroni, Barbara; Blanc, Frederic; Wang, Fen; Sanches, Monica; Lillo, Patricia; Teixeira, Antonio; Caramelli, Paulo; Hudon, Carol; Andrea Slachevsky; Ibáñez, Agustin; Hornberger, Michael; Bertoux, MaximeMeasures of social cognition have now become central in neuropsychology, being essential for early and differential diagnoses, follow-up, and rehabilitation in a wide range of conditions. With the scientific world becoming increasingly interconnected, international neuropsychological and medical collaborations are burgeoning to tackle the global challenges that are mental health conditions. These initiatives commonly merge data across a diversity of populations and countries, while ignoring their specificity. Objective: In this context, we aimed to estimate the influence of participants' nationality on social cognition evaluation. This issue is of particular importance as most cognitive tasks are developed in highly specific contexts, not representative of that encountered by the world's population. Method: Through a large international study across 18 sites, neuropsychologists assessed core aspects of social cognition in 587 participants from 12 countries using traditional and widely used tasks. Results: Age, gender, and education were found to impact measures of mentalizing and emotion recognition. After controlling for these factors, differences between countries accounted for more than 20% of the variance on both measures. Importantly, it was possible to isolate participants' nationality from potential translation issues, which classically constitute a major limitation. Conclusions: Overall, these findings highlight the need for important methodological shifts to better represent social cognition in both fundamental research and clinical practice, especially within emerging international networks and consortia.

Although FTD affects all populations across the globe, knowledge regarding the pathophysiology and genetics derives primarily from studies conducted in North America and Western Europe. Globally, biomedical research for FTD is hindered by variable access to diagnosis, discussed in this group's earlier article, and by reduced access to expertise, funding, and infrastructure. This perspective paper was produced by two professional interest areas of the Alzheimer's Association International Society to Advance Alzheimer's Research and Treatment (ISTAART) and discusses the field's current status on the cross-cultural aspects of basic and translational research in FTD (including that focused on epidemiology, genetics, biomarkers, and treatment). It subsequently provides a summary of gaps and needs to address the disparities and advance global FTD biomedical research.Publication Gaps in clinical research in frontotemporal dementia: A call for diversity and disparities-focused research(2023) Franzen, Sanne; Nuytemans, Karen; Bourdage, Renelle; Caramelli, Paulo; Ellajosyula, Ratnavalli; Finger, Elizabeth; Illán-Gala, Ignacio; Loi, Samantha M.; Morhardt, Darby; Pijnenburg, Yolande; Rascovsky, Katya; Williams, Monique M.; Yokoyama, Jennifer S.; Alladi, Suvarna; Ayhan, Yavuz; Broce, Iris; Castro-Suarez, Sheila; Coleman, Kristy; Cruz de Souza, Leonardo; Dacks, Penny A.; Boer, Sterr C.

FTD's exact clinical presentation varies by culture, language, education, social norms, and other socioeconomic factors; current research and clinical practice, however, is mainly based on studies conducted in North America and Western Europe. Changes in diagnostic criteria and procedures as well as new or adapted cognitive tests are likely needed to take into consideration global diversity. This perspective paper by two professional interest areas of the Alzheimer's Association International Society to Advance Alzheimer's Research and Treatment examines how increasing global diversity impacts the clinical presentation, screening, assessment, and diagnosis of FTD and its treatment and care. It subsequently provides recommendations to address immediate needs to advance global FTD research and clinical practice.Publication Impact of the Pandemic Time on the Mental Health of People with Dementia and Their Family Caregivers in Brazil and Chile: One-Year Follow-Up(2024) Olavarría, Loreto; Caramelli, Paulo; Lema, José; Bezerra, Caíssa; Pinto, Alejandra; Dos Santos, Lílian; Thumala, Daniela; Santos, Maria; Peredo, Adriana; Barroso, Alana; Carvalho, Karoline; Sepúlveda, Walter; Cardoso, Ludmilla; Tonidandel, Maira; Slachevsky Chonchol, AndreaBackground: Previous studies reported the negative impact of social isolation on mental health in people with dementia (PwD) and their caregivers, butlongitudinal studies seem scarcer. Objective: To describe a one-year follow-up impact of the COVID-19 pandemic on PwD and their caregivers in both Brazil and Chile. Methods: This study analyzed the impact of the pandemic on the psychological and physical health of PwD and their family caregivers after one year of follow-up in three outpatient clinics in Brazil (n = 68) and Chile (n = 61). Results: In both countries, PwD reduced their functional capacity after one year of follow-up (p = 0.017 and p = 0.009; respectively) and caregivers reported worse physical and mental health (p = 0.028 and p = 0.039). Only in Chile, caregivers reported more sadness associated with care (p = 0.001), and reduced time sleeping (p = 0.07). Conclusions: In conclusion, the COVID-19 pandemic appears to have had a long-lasting impact on PwD and their caregivers. However, it is essential to acknowledge that the inherent progression of dementia itself may also influence changes observed over a year.Publication Rehabilitation Services for Young-Onset Dementia: Examples from High- and Low-Middle-Income Countries(2024) Suárez, Aida; Savage, Sharon; Alladi, Suvarna; Carvalho, Viviane; Arshad, Faheem; Camino, Julieta; Caramelli, Paulo; Comas, Adelina; Cook, Julia; Cooper, Claudia; García, Laura; Grasso, Stephanie; Jokel, Regina; Lavoie, Monica; León, Tomás; Priya, Thomas; Ramos, Teresita; Taylor, Cathleen; Townsend, Rosemary; Thöne, Angelika; Slachevsky Chonchol, Andrea; Volkmer, Anna; Weidner, Wendy; Mc O'Connor, ClaireThe WHO Dementia Global Action Plan states that rehabilitation services for dementia are required to promote health, reduce disability, and maintain quality of life for those living with dementia. Current services, however, are scarce, particularly for people with young-onset dementia (YOD). This article, written by an international group of multidisciplinary dementia specialists, offers a three-part overview to promote the development of rehabilitation services for YOD. Firstly, we provide a synthesis of knowledge on current evidence-based rehabilitative therapies for early-onset Alzheimer's disease (EOAD), behavioural variant frontotemporal dementia (bvFTD), primary progressive aphasia (PPA), and posterior cortical atrophy (PCA). Secondly, we discuss the characteristics of rehabilitation services for YOD, providing examples across three continents for how these services can be embedded in existing settings and the different roles of the rehabilitation multidisciplinary team. Lastly, we conclude by highlighting the potential of telehealth in making rehabilitation services more accessible for people with YOD. Overall, with this paper, we aim to encourage clinical leads to begin introducing at least some rehabilitation into their services, leveraging existing resources and finding support in the collective expertise of the broader multidisciplinary dementia professional community.
