Topic: Amyloid, tau and blood-test diagnosis

A Doença de Alzheimer (DA) é a principal causa de demência no mundo, caracterizada por processos neurodegenerativos progressivos que comprometem cognição, comportamento e funcionalidade. O diagnóstico precoce permanece desafiador, pois os métodos tradicionais, como análise de líquido cefalorraquidiano e exames de imagem, embora considerados referência, são invasivos, caros e pouco acessíveis em larga escala. Nesse contexto, os biomarcadores periféricos emergem como alternativas promissoras por aliarem menor invasividade, maior viabilidade clínica e potencial para refletir alterações neuropatológicas precoces. O presente estudo objetivou realizar uma revisão da literatura sobre os principais biomarcadores aplicados ao diagnóstico e prognóstico do Alzheimer, incluindo também estudos que avaliem intervenções, como o uso de probióticos, desde que estejam diretamente relacionados à modulação de biomarcadores associados à fisiopatologia, progressão ou detecção precoce da doença. Trata-se de uma revisão integrativa da literatura com base no modelo PRISMA, com seleção de estudos nas bases de dados Portal de Periódicos da PubMed/Medline, Scielo e Biblioteca Virtual em Saúde, empregando os descritores: Alzheimer, biomarcadores, probióticos, em português e inglês, no período de 2019 a 2024. Esta revisão evidencia que os biomarcadores representam ferramentas fundamentais para o diagnóstico precoce e o prognóstico da DA. Enquanto os exames do líquor e de imagem permanecem como padrão, avanços em marcadores periféricos, como p-tau, NfL, GFAP e citocinas inflamatórias, ampliam as possibilidades de aplicação clínica por serem menos invasivos e mais acessíveis. Além disso, estratégias como a suplementação com probióticos e kefir mostram potencial em modular processos relacionados à neuroinflamação e ao estresse oxidativo, sugerindo caminhos promissores para futuras intervenções terapêuticas. A integração entre biomarcadores clássicos, periféricos e inovadores, aponta para um modelo de medicina personalizada e preventiva, essencial para o enfrentamento da DA.

Key findings

Why it matters

This literature review concludes that biomarkers are fundamental tools for early diagnosis and prognosis of Alzheimer's disease, while spinal fluid and imaging tests remain the standard. It discusses peripheral biomarkers and probiotics only as they relate to biomarker modulation, and offers no treatment or cure.
