- A Norwegian team based at the University of Bergen recently performed a population study using the country’s detailed national health registries. With records from more than two and a half million Norwegians, the team examined what, if any, associations could be found between ADHD and nine autoimmune diseases: ankylosing spondylitis, Crohn’s disease, iridocyclitis, multiple sclerosis, psoriasis, rheumatoid arthritis, systemic lupus erythematosus, type 1 diabetes, and ulcerative Read moreAn international team of researchers has carefully examined the best current evidence and found strong evidence for an association between asthma and ADHD by combining a meta-analysis of prior data with a new analysis of the Swedish population. The meta-analysis identified 46 datasets with a total of more than 3.3 million persons. It computed an unadjusted odds ratio (OR) of 1.7, which indicates that ADHD patients have about twice the risk of developing asthma compared with people Read more
by Lenard A. Adler, MD -This two-year study examined the effect of digital media use on ADHD symptoms in over 2500 adolescents. An earlier meta-analysis found that traditional media use (TV and video console games) was modestly associated with ADHD-like behaviors (Nikkelen et al 2014). The current study extends the examination to a large sample, with modern digital media delivery of high-intensity stimuli, including mobile platforms. The authors used the Current Symptom Self-Report Scale (Barkley R 1998) to Read more
by Lenard A. Adler, MD -This article provides a review of the cardiovascular effects of ADHD medications including potential effects on blood pressure, heart rate and risk of cardiovascular events (myocardial infarction, sudden death and stroke). The article notes that meta-analyses have generally found that the effects of stimulant medications and atomoxetine were generally similar on systolic blood pressure (1-3 mm Hg) and heart rate (2-5 beats/minute); these were felt to be of limited clinical significance, Read more
by Lenard A. Adler, MD -This article reviews the phenomenology of emotional dysregulation in adult ADHD. The article discusses whether symptoms of emotional dysregulation (ED) are co-traveling symptoms that travel with symptoms of adult ADHD or whether they are part of the core symptoms of the condition. Symptoms of ED include rapidly shifting affect, changeable mood, mood lability, impulsivity and emotional overactivity. Barkley et al. (7 from article) have posited that ED symptoms are part of a set of Read moreAn international team of researchers recently published a meta-analysis of randomized controlled trials examining the efficacy of meditation-based therapies. Thirteen randomized controlled clinical trials (RCTs) were included: seven, with 270 participants, focused on children and adolescents; the other six, with 339 participants, on adults. Because only one of the RCTs was appropriately blinded, the results discussed below, although promising, must be considered preliminary. Among Read moreA systematic review found five studies that evaluated shared care models involving children and adolescents, in which primary care providers (PCPs) collaborated with mental health care providers in treating ADHD. The 655 participants ranged in age from 5 to 17. Two of the studies were randomized. In one, the largest, with 321 participants, care managers acted as liaisons between PCPs and psychiatrists, and provided psychoeducation and skills training for families. Effect sizes on the Read moreA Spanish team of researchers recently completed a comprehensive review of studies looking for links between compulsive video gaming (both online and offline) and a variety of psychological disorders, including anxiety, depression, social phobia, and ADHD. The focus was on behavior “of sufficient severity to result in significant impairment in personal, family, social, educational, occupational or other important areas of functioning.” The team identified 24 studies, of which eight with Read moreWe are only beginning to explore how ADHD affects sleep in adults. A team of European researchers recently published the first meta-analysis on the subject, drawing on thirteen studies with 1,439 participants. They examined both subjective evaluations from sleep questionnaires and objective measurements from actigraphy and polysomnography. However, due to differences among the studies, only two to seven could be combined for any single topic, generally with considerably fewer participants Read moreA systematic review of the literature found seven studies examining this question. Significantly, six were large cohort studies with a combined total of almost three million individuals. The other was a large case-control study with 7,874 participants. The largest cohort study, with more than a million and a half children, found that prenatal antidepressant exposure increased the risk for ADHD. The adjusted odds ratio was 1.6 for any antidepressant and for selective serotonin reuptake Read more
