Description

Rinsho Shinkeigaku is the official journal of the Japanese Society of Neurology that has been providing useful information to neurologists in Japan. Titles of articles published in Rinsho Shinkeigaku were analyzed by the morphological analysis to review what the Japanese Society of Neurology provided. We analyzed the titles of 7,450 articles. Multiple sclerosis and autopsy were the most frequently occurring disease name/category and medical term, respectively. The medical terms of antibody and gene were first used around 1980, and their usage gradually increased thereafter. The use of the terms computed tomography (CT) and magnetic resonance imaging (MRI) peaked around 1990 and thereafter decreased until 2010. The frequency variation in the use of disease names and medical terms reflects the trend in Neurology and the areas of interest of the neurologists.
