Background and Objective: Comparable data are sparse for infl ammatory demyelinating diseases of the central nervous system (CNS) in the Asia-Pacifi c region, and we aimed to establish a registry of patients with such diseases in the region. Methods: A network of neurologists in the Asia-Pacifi c Region was established to register patients with the targeted diseases. A standardized register form and relevant instructions in English, translated into the local language when needed, were prepared before the study start and used for data collection. Results: Eight study centres from different countries/areas participated in the study. In total, 857 patients with a validated diagnosis of different infl ammatory demyelinating diseases of the CNS were registered, 591 females and 266 males with a female-to-male ratio 2.2. The mean age at onset for all patients was 35.9 (SD: 12.9) years, signifi cantly younger (p = 0.010) for females (35.1 years, SD: 12.6 years) than for males (37.6 years, SD: 13.4 years). Conclusion: Patients with different infl ammatory demyelinating diseases of the CNS were in the fi rst time registered in a multi-centre study from eight countries/areas in the Asia-Pacifi c region. A platform and basis has been established for further study in the fi eld.

The common cerebral small vessel disease (CSVD) neuroimaging features visible on conventional structural magnetic resonance imaging include recent small subcortical infarcts, lacunes, white matter hyperintensities, perivascular spaces, microbleeds, and brain atrophy. The CSVD neuroimaging features have shared and distinct clinical consequences, and the automatic quantification methods for these features are increasingly used in research and clinical settings. This review article explores the recent progress in CSVD neuroimaging feature quantification and provides an overview of the clinical consequences of these CSVD features as well as the possibilities of using these features as endpoints in clinical trials. The added value of CSVD neuroimaging quantification is also discussed for researches focused on the mechanism of CSVD and the prognosis in subjects with CSVD.
