Nas margens de um sistema de saúde historicamente desigual, pesquisadores brasileiros da UFRGS avançam com uma descoberta que pode redefinir o acesso ao diagnóstico precoce do Alzheimer: um exame de sangue capaz de identificar a doença com 90% de precisão. Onde antes havia apenas procedimentos dolorosos e caros — inacessíveis a milhões de brasileiros pobres e distantes dos grandes centros —, surge agora a possibilidade de um diagnóstico simples, realizado em qualquer clínica do país. A ciência, aqui, não apenas responde a uma pergunta médica; ela questiona quem merece ser visto pelo sistema an
