Review of the diagnosis and clinical features of multiple sclerosis in China.

This review focused on the diagnosis and clinical features of multiple sclerosis (MS) in China. We have identified the published researching information from 1976 to 2008 in China. The key issues related to the diagnosis and clinical features of MS in China were summarized. The first patient with MS in China was reported in 1926 from Xiehe hospital. Case reports on MS have been increasing during recent decades. Almost all the patients with MS were confirmed by the McDonald criteria (1977) before 1984. After the year of 1992, even to this day, the Poser criteria were widely used in China. Although the new diagnostic criteria, McDonald criteria (2001), were presented in 2001, only few papers published in Chinese were reported. The most frequent initial symptoms or signs of the patients with MS were optic nerve, motor weakness and sensory symptoms. The most frequent location of MS lesions over the course was found to be the spinal cord, followed by the cerebrum and optic nerves. Almost all patients had been treated with corticosteroids. This review supported previous observations in Chinese patients with MS. However, further studies are needed to understand epidemiologic features of MS in China.
