Many studies have correlated low greenspace and high air pollution with a child’s risk of developing attention-deficit/hyperactivity disorder (ADHD). However, studies conducted at the population level are limited. This study, published in ​​Environment International, investigated the association among ADHD incidence and air pollution, noise, and greenspace in a population-based birth cohort.  The cohort was assembled...

Attention deficit hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) commonly co-occur. However, the two conditions are generally studied separately. This study, published in the Journal of Attention Disorders, sought to evaluate the typical trajectories of these disorders and how they co-develop in early childhood. A total of 273 parents who participated in the study completed...

Irritability is associated with more severe clinical presentations and poorer longitudinal outcomes among individuals with ADHD. This study, published in BMC Psychiatry, looks at the cognitive mechanisms underlying irritability in individuals with ADHD. The researchers hypothesized that increased irritability would be associated with hot executive functions involving emotional contexts rather than with cool executive functions involving abstract...

New evidence shows that stimulants have sensitization effects on the brain. These effects have been shown to result in neurophysiological changes to the brain’s reward system, some of which could be long-lasting. This study, published in Neuroscience & Biobehavioral Reviews, reviews the risk for substance abuse and the development of substance use disorder (SUD) in people...

The Quantified Behavioural Test Plus (QbTest+) is a test commonly used to assess patients with ADHD.

Cervical cancer surgery can often result in irreversible damage to the pelvic nerves. This study, published in the European Journal of Nuclear Medicine and Molecular Imaging, examines the feasibility and safety of intraoperative near-infrared fluorescence imaging (NIR-FI) with indocyanine green in identifying pelvic nerves during radical hysterectomy for cervical cancer. A total of 66 patients with cervical...
