Authors of new Cochrane Review remain uncertain about effect of widely used medicine on ADHD symptoms, despite large amount of research. Some evidence of increased sleeplessness and loss of appetite leads researchers to encourage more caution in use of methylphenidate

A comprehensive Cochrane Review shows there is very low-quality evidence to support the use of methylphenidate (Ritalin, Concerta, other brands) in children with attention deficit hyperactivity disorder (ADHD) leading the reviewers to urge more caution when prescribing the stimulant

Iron, a common mineral (and, paradoxically, a common mineral deficiency in humans) is important to the brain and vital for normal brain development and human behavior. It is a key cofactor in the making of neurotransmitters, chemicals in the brain that affect neuron signaling, including serotonin, norepinephrine, and especially dopamine. Iron is also necessary for the enzyme monoamine oxidase to break down these neurotransmitters

Neuroscientists at UMass Medical School have discovered a molecular braking mechanism for the brain chemical dopamine that may lead to more effective treatments for some forms of attention deficit hyperactivity disorder (ADHD) and other mental health disorders in which abnormal dopamine function plays a central role

Many elementary school children with attention deficit hyperactivity disorder (ADHD) don’t get services like medication and behaviour therapy that might improve their condition, according to an Australian study. The condition’s impact on the family and the child’s age are the biggest determinants of whether parents tap into available services, researchers found

At least two things about attention deficit/hyperactivity disorder are certain: Diagnoses are increasing, and American parents’ concerns about the condition are skyrocketing...A new addition to the voluminous literature about the disorder may offer some clarity
