Methylphenidate induced acute psychosis in a case with mild intellectual disability and ADHD.

Methylphenidate (MPH) is used as the first line drug for treating the attention deficit hyperactive disorder (ADHD). Therapeutic dose of MPH is known to causes psychotic symptoms in a small number of cases and these symptoms usually disappear on discontinuing MPH. Here we describe a case of 11 years old boy with diagnosis of ADHD and mild intellectual disability, who was treated with methylphenidate and later developed acute psychosis. [ABSTRACT FROM AUTHOR]
