A recently published study on children, ADHD, and sleep, gives parents good reasons to make sure that their ADHD kids develop good bed-time habits and are in bed as early as possible.

The study was just published on March 1, 2009 in the journal SLEEP. It confirms what many parents already know about their ADHD children or teens, that they simply are not getting enough sleep at night, and that they often wake up tired and sluggish in the morning, which causes other problems all through the day.

New Research Offers Insight Into Cause Of Impulsivity in ADHD

We have often felt sorry for those impulsive children who blurt out the first thing that comes to their mind when asked a question, especially if they are about to get into trouble. As most parents know, that first thing that comes out as the answer is usually a lie. And then the child has to spend the rest of the hour covering up the lie, that both he and his parents know is a lie. This is a classic scene of a child with ADHD getting into trouble because of his impulsivity. Read more of the article...

Neurophysiological correlates of Attention Deficit Disorder with and without Hyperactivity (AD/HD) and effects of methylphenidate are explored using electroencephalographic (EEG) and auditory eventrelated potentials (ERPs).

In the first of four studies, a database of AD/HD individuals of varying ages and matched adolescent/adult controls is presented.

Study 2 compares controls and age-matched children with ADD, and children with ADHD on and off methylphenidate. Read more of the article...

In this paper, we consider the domain of executive functions (EFs) and their possible role in developmental psychopathologies.

We first consider general theoretical and measurement issues involved in studying EFs and then review studies of EFs in four developmental psychopathologies: attention deficit hyperactivity disorder (ADHD), conduct disorder (CD), autism, and Tourette syndrome (TS).

Our review reveals that EF deficits are consistently found in both ADHD and autism but not in CD (without ADHD) or in TS. Read more of the article...

The neuropsychological functioning of adults with Attention Deficit Hyperactivity Disorder (ADHD) was compared to that of healthy controls and individuals with mild psychiatric disorders including attentional complaints.

Thirty adults in each group were examined on the Conners' Continuous Performance Test (CPT) and measures of attention, executive function, psychomotor speed, and arithmetic skills.

The ADHD group performed lower than healthy controls on most measures. Read more of the article...
