ADHD study reveals unique genetic differences in African American patients

Researchers have shown there may be key genetic differences in the causes of attention-deficit hyperactivity disorder (ADHD) between African Americans and people of European ancestry, which may play an important part in how patients of different ethnic backgrounds respond to treatments for this condition.

Persistence of ADHD into adulthood is an important predictor of car crash risk

A new study reports that the risk of being involved in car crashes increases for those diagnosed with attention-deficit/hyperactivity disorder (ADHD). The study looked specifically at the rate of car crashes by adulthood, which was 1.45 times higher in those with a childhood history of ADHD compared to adults with no ADHD.

New study suggests ADHD- like behavior helps spur entrepreneurial activity

Many people have experienced a few nights of bad sleep that resulted in shifting attention spans, impulsive tendencies and hyperactivity the next day -- all behaviors resembling ADHD. A new study found that this dynamic may also be linked to increased entrepreneurial behavior.

A shorter IQ test for children with special needs

For decades, neuropsychologists have used the Wechsler Intelligence Scale for Children test as the gold-standard intelligence quotient (IQ) test to determine the intellectual abilities of children with special needs. However, this comprehensive test can take up to 2 hours to complete, and many children with special needs have a difficult time participating...

Genomic analysis in samples of Neanderthals and modern humans shows a decrease in ADHD-associated genetic variants

The frequency of genetic variants associated with attention-deficit/hyperactivity disorder (ADHD) has decreased progressively in the evolutionary human lineage from the Paleolithic to the present day, according to new research.

Genetics linked to childhood emotional, social and psychiatric problems

Emotional, social and psychiatric problems in children and adolescents have been linked to higher levels of genetic vulnerability for adult depression.

Learning difficulties due to poor connectivity, not specific brain regions

Different learning difficulties do not correspond to specific regions of the brain, as previously thought, say researchers. Instead poor connectivity between 'hubs' within the brain is much more strongly related to children's difficulties.

Vitamin D deficiency during pregnancy connected to elevated risk of ADHD

The risk of ADHD was 34 percent higher in children whose mother had a vitamin D deficiency during pregnancy than in those children whose mother's vitamin D level was sufficient during the first and second trimesters. The result was adjusted for maternal age, socioeconomic status and psychiatric history.

Kids diagnosed with ADHD often don't take medication regularly

Children diagnosed with ADHD inconsistently take their prescribed medication, going without treatment 40 per cent of the time, a new study has found.

Rich rewards: Scientists reveal ADHD medication's effect on the brain

Researchers have identified how certain areas of the human brain respond to methylphenidate -- a stimulant drug which is used to treat symptoms of ADHD. The work may help researchers understand the precise mechanism of the drug and ultimately develop more targeted medicines for the condition.
