摘要
背景:由于缺乏早期诊断的生物标志物,阿尔茨海默氏病(AD)很难诊断。早期的AD患者,视觉下降皮质神经退行性疾病有关是公认的,但最近的研究已经表明,比起脆弱的大脑区域,如皮质和海马,视网膜可能更容易受到影响。在这篇综述中,我们讨论了研究结果,这些研究表明视网膜的功能改变可能成为最早的诊断AD的生物标志物。 方法:通过关注于主题,对同行评审的研究文献的书目数据库进行分析,使用标准的包含/排除法,即视网膜突触功能障碍与大脑回忆变化有关。 结果:共有134篇论文被纳入研究,大多数(52)与处理最早的突触功能障碍和脆弱脑区的神经网络有关,并指出他们如何可能激发视网膜的类似研究。在随后的40和31篇论文的分析的基础上,分别讨论了AD晚期患者的视网膜组织和视网膜改变。最后,我们提出了证据(11篇论文),并表明通过使用现代成像和功能技术和非侵入性的的检测,视网膜突触功能障碍成为最早诊断AD的潜力。

摘要: Background: Alzheimer's disease (AD) develops undetected for years due to the lack of early diagnostic biomarkers. In advanced AD, visual deficits related to cortical neurodegeneration are well recognized, but recent studies have identified that the retina could be affected prior to vulnerable brain areas such as cortex and hippocampus. In this review, we discuss a new evidence suggesting that functional alterations in the retina may become the earliest diagnostic biomarkers for AD.
Methods: Analytical analysis of bibliographic databases for peer-reviewed research literature was performed by focusing on the review topic and using standard inclusion/exclusion criteria in the context of the given conceptual framework i.e., that synaptic dysfunction within the retina may be reminiscent of changes within the brain. Results: A total of 134 papers were included in the review, the majority (52) dealing with the earliest dysfunction of synaptic and neuronal networks in vulnerable brain areas to point out how they may inspire the analogous research in the retina. The general aspects of retina organization and the retinal alterations in the late stages of AD are then discussed based on the analysis of the next 40 and 31 papers, respectively. We finally present evidence (11 papers) indicating why putative retinal synaptic dysfunction holds the potential to become the earliest sign of AD, allowing for a non-invasive and easy detection using modern imaging and functional techniques. Conclusion: Translation of these findings to clinical diagnosis could lead to earlier therapeutic interventions and, consequently, better chances to delay or halt AD progression.Export Options
