In Sweden prevalence is especially high in urban areas with estimates of up to 10% in teenage boys in Stockholm. Some studies have indicated that diagnosed ADHD is more common in higher socioeconomic areas whereas the symptom load of ADHD is higher in lower socioeconomic areas.

At this journal club we will discuss the study by Rydell et al (2018) and the design that was used in the study to evaluate the above question. We will also discuss if perhaps a more symptom based approach is a good complement in the clinical setting for reducing the progress into some of the negative life outcomes.

The article that will be discussed:

Rydell, M., Lundström, S., Gillberg, C., Lichtenstein, P., & Larsson, H. (2018). Has the attention deficit hyperactivity disorder phenotype become more common in children between 2004 and 2014? Trends over 10 years from a Swedish general population sample. The Journal of Child Psychology and Psychiatry59, 863– 871

The journal club will be lead by doctoral student Annika Tiger.
