另一项研究放大了我们经常认为理所当然的东西:我们的大脑是如何理解我们所看到的东西的。对于患有 HD 的人来说,辨认面孔、阅读书籍甚至在杂货店购物都会变得异常困难。西班牙的研究人员进行了一系列巧妙的视觉思维测试,比如根据记忆画出形状,以找出这些挑战何时以及如何出现。
情节曲折?在典型的 HD 症状出现之前,视觉记忆就可能出现微妙的变化。这为早期诊断和更好的规划提供了机会。因为这不仅与眼睛看到的东西有关,还与大脑如何解读它有关。及早发现这些变化可以鼓励人们使用有用的视觉提醒,从而在日常生活中发挥重要作用。
亨廷顿氏病的 DNA 修复:达不到标准?
越来越多的证据表明,HD 会影响 DNA 修复。雷-特鲁恩特(Ray Truant)博士团队的一项新研究表明,扩大的 HTT 会减缓一种名为 PAR 的关键 DNA 修复分子的生成,而 PAR 通常会标记出受损的 DNA。如果没有足够的 PAR,HD 细胞就会任由损伤堆积,可能会助长那些邪恶的 CAG 重复序列的扩展,从而导致这种疾病。
HD 可对口腔健康造成严重破坏。最近的一项研究显示,HD 患者面临着许多牙科方面的挑战:行动不便使刷牙成为一件苦差事,饮食习惯的改变偏爱容易导致龋齿的食物,许多牙医对 HD 患者的特殊需求毫无准备。再加上焦虑、经济压力和行动障碍,难怪牙科护理常常被搁置一旁。
但希望还是有的!文章强调,只要有正确的知识和准备,牙科专业人员就能发挥重要作用。通过了解 HD 的影响并调整护理策略,他们可以帮助患者保持更健康的笑容并提高他们的生活质量。这篇综述的发表证明了有关 HD 的信息正在牙科界传播。因此,让我们向那些准备迎头解决 HD 牙科难题的牙医们致敬–因为每个人都应该有微笑的理由。
