Stimulants’ ADHD calming mechanism revealed

When Dr. Charles Bradley administered Benzedrine to a group of children with hyperactivity in 1937 a new era of psychopharmacology was born. His observation that “fourteen children responded in a spectacular fashion” ushered in the widespread use of methamphetamine-like drugs to treat hyperactivity and learning disorders. But for more than seven decades scientists have not […]

Inner-ear disorders may be key to ADHD

Behavioral abnormalities are traditionally thought to originate in the brain, but researchers at the Albert Einstein College of Medicine have found that inner-ear dysfunction can directly cause neurological disorders such as hyperactivity. Their intriguing study, published inScience, implicates two brain proteins that could be targets for novel interventions. “Our study provides the first evidence that […]

Medicos mull possible link between obesity and ADHD

A new University of Illinois study has established a possible link between high-fat diets and childhood cognitive conditions such as attention deficit hyperactivity disorder (ADHD) and memory-dependent learning disabilities. The research, published inPsychoneuroendocrinology, found that altered dopamine signaling (previously associated with anxiety behaviors in children) in the brain is common to both ADHD and the […]

Intestinal protein linked to ADHD

Researchers are increasingly linking gut function to a variety of neuropsychiatric disorders. Now, a new study suggests that a biochemical pathway long associated with diarrhea may provide a new therapeutic target for treating Attention Deficit Hyperactivity Disorder (ADHD). The researchers, from China and the United States, report on their findings in Science. The intestinal membrane […]

New evidence that ADHD is genetic

The results of genetic analysis of children with attention-deficit/hyperactivity disorder (ADHD) published in The Lancet reveal they were more likely to have small segments of their DNA duplicated or missing, lending new weight to the unfashionable theory that ADHD is a brain disorder with genetic links. The study also found a significant overlap between these […]

Brain plasticity increased with Ritalin use

Millions of children are treated with Ritalin to improve their ability to focus on tasks, but scientists now report that Ritalin also directly enhances the speed of learning. The scientists, from the University of California – San Francisco, showed for the first time that Ritalin boosts both of these cognitive abilities by increasing the activity […]

Plastics chemicals linked to ADHD symptoms

Adding to concerns that phthalates are feminizing boys’ brains and causing genital deformities, Korean scientists say they now have evidence linking attention-deficit/hyperactivity disorder (ADHD) symptoms to the ubiquitous chemicals. Phthalates are widely used chemical components of many consumer products, including toys, cleaning materials, plastics, and personal care items. Now, a new report published in Biological […]

ADHD A Benefit In The Wild?

A fascinating new study in the journal BMC Evolutionary Biology suggests that attention deficit hyperactivity disorder (ADHD) might be beneficial to nomadic Kenyan tribesmen in Africa, while possibly leading to malnourishment in their settled cousins. Led by Dan Eisenberg, an anthropologist from Northwestern University, the study looked at occurrences of the ADHD-associated version of the […]

ADHD Drug Affects Developing Brain

Ritalin – used to treat attention deficit/hyperactivity disorder – may cause long-term changes in children’s brains, suggests a new study from the Weill Cornell Medical College. While figures are vague, up to 18 percent of American children are thought to be affected by ADHD and Ritalin, a stimulant similar to amphetamine, is one of the […]
