Does ‘internet addiction’ change the brain?

While this small study has found patterns in brain volume among people with IAD, it is not appropriate to assume that internet addiction causes changes to the brain, particularly as we cannot tell how their brains were structured before they began using the internet. Also, the study featured just 36 participants, meaning its results should be treated with caution.

Importantly, the changes described in this study were to the brains of adolescents with a specific, if new, disorder, and the brains of people who simply use the internet on a day-to-day basis were not assessed.
