Problematic usage of the internet and cognition

In this current opinions article we synthesize recent evidence exploring neurocognitive deficits in problematic usage of the internet, which support the notion that inhibitory control and decision making deficits occur in problematic usage versus controls, strengthening its theoretical conceptualization. Potential confounders, notably IQ and the presence of comorbidities from the impulsive/compulsive spectrum may account for some of these identified deficits. Most studies focused on gaming, whereas other facets remain relatively understudied. The literature has high levels of methodological issues, such as using non-validated thresholds/instruments, examining only a narrow range of cognitive domains, and overlooking potentially confounding comorbid disorders. Longitudinal studies with rigorous methodologies are needed to address whether cognitive problems associated with problematic internet use play a role in vulnerability, chronicity, or both.
