Journal Article
Man, K. K., Coghill, D., Chan, E. W., Lau, W. C., Hollis, C., Liddle, E., …Wong, I. C. (in press). Methylphenidate and the risk of psychotic disorders and hallucinations in children and adolescents in a large health system. Translational Psychiatry, 6, Article e956. https://doi.org/10.1038/tp.2016.216

Previous studies have suggested that risk of psychotic events may be increased in children exposed to methylphenidate (MPH). However, this risk has not been fully examined and the possibility of confounding factors has not been excluded. Patients age...
