Methylphenidate is a medication to control the symptoms of attention deficit hyperactivity disorder (ADHD). This drug is also used in the treatment of narcolepsy, a sleep disorder that causes sufferers to fall asleep suddenly

Methylphenidate works by balancing the levels of chemical compounds in the brain (neurotransmitters), namely dopamine and norepinephrine in the brain. That way, concentration and focus can be increased, and behavioral disturbances can be controlled.
