Studies published in JAMA Neurology in 2019 featured a breadth of diverse and highly influential investigations. Here, we highlight a few of many exciting studies from the past year that illustrate major strides in neurology across fields from a lens of varied experimental approaches.

Randomized clinical trials (RCTs) play a vital role in health care decision-making, so we have been particularly pleased by the increasing number of high-profile RCTs published in JAMA Neurology. Several of these in the fields of stroke, pain, and behavioral neurology promise to directly inform practice and policy—and thus quickly affect care delivery.

2019年《美国医学会杂志神经病学》（JAMA Neurology）上发表的研究涵盖了广泛且影响深远的研究。在这里，我们重点介绍了过去一年中许多令人兴奋的研究，这些研究从各种实验方法的角度说明了跨领域神经学的重大进步。

随机临床试验（RCT）在卫生保健决策中起着至关重要的作用，因此，我们对JAMA Neurology上发表的备受瞩目的RCT数量不断增加感到特别满意。中风，疼痛和行为神经病学领域的其中一些有望直接指导实践和政策，从而迅速影响医疗服务。
