Update: Here’s my international ADHD support group page which includes a South African ADHD support group organization with multiple chapters, ADHASA Attention Deficit Hyperactivity Association of Southern Africa for Children and Adults
Here’s an article on a study that replicated an ADHD study conducted in Norway, with children from the Limpopo province in the Republic of South Africa. Moment-to-moment dynamics of ADHD behaviour in South African children. Overall, the results replicated the findings from Norway.
CONCLUSIONS: The present study makes a strong case for ADHD as a basic, neurobehavioural disorder, not a cultural phenomenon, by replicating findings from a wealthy Western country in a poor province of a developing country. The results were, generally, in line with predictions from the dynamic developmental theory of ADHD by indicating that reinforcers were less efficient in the ADHD group than in the non-ADHD group. Finally, the results substantiated ADHD-related variability as an etiologically important characteristic of ADHD behaviour.
Some more ammunition to use when someone claims that ADHD is just “a made up American disease”
