  • Are Executive Function Deficits Separate from ADHD?

    This blog addresses the relationship between executive function deficits in general and working memory (WM) deficits in particular and attention-deficit/hyperactivity disorder (ADHD).  Although some neuropsychological models of ADHD have proposed that ADHD arises from deficits in executive functions, accumulating clinical evidence show that it afflicts some but not all individuals with ADHD and suggests that ADHD and executive function deficits represent separate clinical

  • Side Effects of Acetaminophen – ADHD?

    The use of acetaminophen by pregnant women in one study showed increased risk for ADHD in the child. However, looking at more studies, the results are not yet conclusive.
  • Acetaminophen and ADHD

    Many media outlets have reported on a study suggesting that mothers who use acetaminophen during pregnancy may put their unborn child at risk for ADHD. Given that acetaminophen is used in many over-the-counter pain killers, correctly reporting such information is crucial. As usual, rather than relying on one study, looking at the big picture using all available studies is best. Because it is not possible to examine this issue with a randomized trial, we must rely on naturalistic

  • Broken Bones and ADHD

    Although some people view the impulsivity and inattentiveness of ADHD adults as a normal trait, these symptoms have adverse consequences, which is why doctors consider ADHD to be a disorder. The list of adverse consequences is long and now we can add another: broken bones. A recent study by Komurcu and colleagues examined 40 patients who were seen by doctors because of broken bones and 40 people who had not broken a bone. After measuring ADHD symptoms in these patients, the study found that

  • ADHD in Older Adults – The Next Clinical Frontier

    As ADHD Adults grow older, clinicians and researchers are learning more about how ADHD symptoms change through the lifespan and how to differentiate ADHD in Older Adults from other aging conditions.
  • Adult Onset ADHD

    Adult Onset ADHD: Does it Exist? Is it Distinct from Youth Onset ADHD? There is a growing interest (and controversy) about ‘adult’ onset ADHD. No current diagnostic system allows for the diagnosis of ADHD in adulthood, yet clinicians sometimes face adults who meet all criteria for ADHD, except for age at onset. Although many of these clinically referred adult onset cases may reflect poor recall, several recent longitudinal population studies have claimed to detect cases of adult onset ADHD

  • Is ADHD Always a Childhood Onset Disorder?

    Is ADHD Always a Childhood Onset Disorder? by Joseph Biederman, MD - August 4, 2016 Recent population based studies raise the intriguing question as to whether adult ADHD is always preceded by childhood onset of symptoms or can develop anew in adult life. From Brazil, one group argues that child and adult ADHD are “distinct syndromes”; from the United Kingdom (UK), another group states that adult ADHD is “more complex than a straightforward continuation of the childhood disorder” and from
