RESUMO
Introduction: The Brazilian population in the United States (U.S.), a Latinx subgroup, is rapidly growing and aging but remains underrepresented in U.S. health research. In addition to group-specific genetic and environmental risks, Brazilian immigrants and their offspring in the U.S. likely have cumulative risks for health inequities.It is estimated that 71% of Brazilian immigrants in the U.S. are undocumented, which may limit healthcare access/utilization. Furthermore, mental health is reported as a health priority by Brazilian immigrants in the U.S., and there is a lack of research on Alzheimer's disease and related dementia (AD/ADRD) in this population. Methods: We reviewed the scientific literature using traditional (e.g., PubMed) sources and databases generated by U.S. and Brazilian governments, as well as international organizations, and press articles. Results: This perspective review lists recommendations for researchers, health providers, and policymakers to promote greater inclusion of U.S. Brazilian populations in health research and care. The review identifies research areas in need of attention to address health inequities and promote mental/brain health in Brazilian immigrants and their offspring living in the U.S. These research areas are: 1) epidemiological studies to map the prevalence and incidence of mental/brain health conditions; 2) research on aging and AD/ADRD risk factors among Brazilian populations in the U.S.; and 3) the need for greater representation of U.S-residing Brazilian population in other relevant research areas involving genetics, neuropathology, and clinical trials. Conclusions: The recommendation and research efforts proposed should help to pave the way for the development of community-engagement research and to promote mental/brain health education, improvement of mental/brain health and AD/ADRD services, and the development of culturally-informed intervention to the U.S.-residing Brazilian communities. HIGHLIGHTS: The Brazilian population in the United States is growing but is underrepresented in U.S. health research.Approximately 71% of Brazilian immigrants in the United States are undocumented, with an increased risk for health inequities.Mental health is reported as a central health priority by Brazilian immigrants in the United States.There is a lack of research on Alzheimer's disease and other dementias (ADRD) in Brazilian immigrants in the United States.Epidemiological research is needed to map the prevalence/incidence of mental health conditions and ADRD risk factors among Brazilian immigrants in the United States.
RESUMO
Se investiga las actividades EEG normales, fronterizas y anormales en 132 niños "normales" que atendieron regularmente al 2§ y 4§ año de una escuela primaria federal en la Ciudad de México; con el objeto de determinar hasta que punto del EEG convencional pudo proporcionar datos subclínicos en los niños con pobre rendimiento escolar (PRE) y aquellos con una historia clínica patológica (AP) y en los controles (C). Se realizó un análisis comparativo de los signos EEG principales entre 2 grupos principales (PRE y C) y 4 subgrupos (PRE + AP, PRE + NoAP, C + AP, C + NoAP). 1.- Los signos anormales fueron significativamente mas frecuentes en el PRE que en el C; y el Pre + AP que en C + AP. 2.-Los signos normales atípicos consistentes en una actividad alfa de gran amplitud y asimetría inconstante, y los signos normales focales paroxisticos y no paroxisticos se encontraron solamente en los grupos PRE y PRE + AP. 3.- La "ondas de sueño" fronterizas se encontraron solamente en los grupos PRE + APy PRE + NoAP; mientras que los potenciales polifásicos solamente se encontraron en los grupos PRE + APyC + AP. 4.- La respuesta excesiva a la hipertiventilación fue significativamente más frecuente en el grupo C que en el PRE y en el C + No AP que en el PRE + AP
