Methylphenidate is part of a therapy regimen for the control of the symptoms of Attention Deficity Hyperactivity Disorder or ADHD in adults and children (Ogbru 2013, Medline Plus 2012). It stimulates the central nervous system similarly as amphetamines but more mildly. The effects of methylphenidate are also more noticeable on mental activities than in physical movements. It also is used in treating narcolepsy and Attention Deficit Disorder or ADD.
