  • Are Shared Care Models Effective in Treating Childhood ADHD?

    A 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

  • Is There a Relationship Between ADHD and Internet Gaming Disorder?

    A 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

  • To What Extent Does ADHD Affect Sleep in Adults, and In What Ways?

    We 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

  • Is Prenatal Antidepressant Exposure a Risk Factor for ADHD?

    A 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

  • High Dropout Rate in Six-Year Cohort Study of Medication Treatment for ADHD

    Few studies have examined the safety and tolerability of ADHD medications (stimulants and atomoxetine) extending beyond six months, and none beyond a few years. A pair of Swedish neuroscientists at Uppsala University Hospital set out to explore longer-term outcomes. They conducted a six-year prospective study of 112 adults diagnosed with ADHD who were being treated with ADHD medications (primarily MPH, but also dexamphetamine and atomoxetine). They found that at the end of that period,

  • The State of the Art on Identifying and Treating Persons with Comorbid ADHD and Substance Use Disorders

    An international group of twelve experts recently published a consensus report examining the state of the evidence and offering recommendations to guide screening, diagnosis, and treatment of individuals with ADHD-SUD comorbidity.[1] In a clear sign that we are still in the early stages of understanding this relationship, five of the thirteen recommendations received the lowest recommendation grade (D), eight received the next-lowest (C), and none received the highest (A and B). The

  • Is Prenatal Exposure to Bisphenol A (BPA) Associatd with Childhood ADHD?

    A team of U.S. endocrinologists recently published the results of a meta-analysis examining a possible association between bisphenol A (BPA) and childhood ADHD. BPA is used in a variety of consumer products, including plastic bottles for food and drink, epoxy resins used to line cans of food, dental sealants, and the thermal receipts issued by stores. A review of the literature found 29 rodent studies but only three with humans. The human studies were too different from each other to be

  • Self vs Clinician Rating Scales

    Silverstein et al. (2017) recently published a study which reported a validation of two expanded adult ADHD scales, self-report (Adult ADHD Self Report Rating Scale (ASRS) v1.1 Symptom Checklist) and clinician/investigator (Adult ADHD Investigator Symptom Rating Scale - AISRS); both scale were expanded beyond the classic 18 DSM symptoms of inattention (IA) and hyperactivity-impulsivity (HI) to include 13 additional commonly co-traveling items of executive function deficits (EFDs) (eg.

  • ADHD Screener

    Ustun et al. (2017) recently published an updated version of the adult ADHD screener which is validated for DSM-5: the ASRS v1.1 Screener: DSM-5. The prior DSM-IV version of the screener was established using two populations: a community-based sample from the National Co-Morbidity Survey (NCS-R) and a sample of individuals from a health care plan. The first step was to recalibrate the new screener using these same two samples, but applying updated DSM-5 criteria; symptoms included not only

    ADHD and Eating Disorders

    ADHD Affects the Efficacy of Treatment for Eating Disorders in Adult Women Swedish researchers examined outcomes for adult women who sought treatment at the Stockholm Centre for Eating Disorders over a period of two years and nine months. Out of 1,517 women who came to the clinic 1,143 remained eligible for the study, after excluding women whose symptoms did not fulfill the DSM-IV criteria for eating disorders or had incomplete records. Of these, seven hundred patients could not be
