The most recent analysis from the MSBase Study Group has examined how treatment decision-making affects the risk of conversion to secondary-progressive multiple sclerosis (SPMS) (Brown et al. JAMA 2019;321:175-187). The results indicate that starting with a higher-efficacy disease-modifying therapy (DMT) or switching earlier can substantially reduce the risk of SPMS. Read More

FDA advisors recommend intranasal ketamine in depression
February 20, 2019Two FDA advisory committees have voted 14-2 in favour of the use of esketamine for treatment-resistant depression (TRD).

Always online: problem or addiction?
February 13, 2019“Internet addiction” was first described in the dial-up era (Young KS. Psychol Rep 1996;79:899-902), with the prevalence steadily increasing with more widespread internet access.

More recent estimates have found a prevalence of 17.7% among adolescents in rural Japan (Kojima et al. Psychiatry Clin Neurosci 2019;73:20-26), and 38.2% among university students in Japan (Kitazawa et al. Psychiatry Clin Neurosci 2018;72:531-539).
