20.500.12556/DKUM-96820 Negativni učinki pretirane uporabe interneta na kognitivne funkcije pri mladostnikih in mladih odraslih Negative effects of excessive internet use on cognitive functions in adolescents and young adults Uvod: Mladostniki zaradi intenzivnih razvojnih sprememb predstavljajo rizično skupino za razvoj internetne zasvojenosti (IA) in motnje igranja iger (IGD). Prevalenca se med regijami razlikuje, k ranljivosti pa prispevajo čustvena deregulacija, impulzivnost, ADHD ter neugodne socialne razmere. Metode: Pri raziskavah, ki temeljijo na psiholoških dejavnikih, vedenjskih vzorcih ter nevrobioloških spremembah, povezanih s pretirano uporabo interneta pri mladih, smo izvedli pregled znanstvene literature v podatkovnih bazah PubMed, CINAHL in Sage Journals, pri čemer smo uporabili vnaprej pripravljeni iskalni niz. Rezultati: Najpogostejši motiv uporabe interneta sta zabava in družbena interakcija. Pretirana raba je povezana s slabšimi strategijami spoprijemanja, kognitivno togostjo, socialnim umikom, depresivnostjo, težavami s spanjem ter akademskim upadom. Pri IGD so bolj ogroženi moški in impulzivni posamezniki. Nevrobiološke študije kažejo spremembe v frontalnih, insularnih, temporalnih in okcipitalnih predelih ter disfunkcionalne povezave med omrežji DMN, ECN, DAN in SN, kar vpliva na pozornost, inhibicijo in čustveno regulacijo. Razprava in zaključek: IA in IGD predstavljata večplastni problem, ki vključuje psihološke, socialne in nevrobiološke dejavnike. Spremembe v možganskih mrežah kažejo na oslabljen kognitivni nadzor, vendar nekateri izsledki opozarjajo na možne kompenzatorne mehanizme. Preventiva in intervencije bi morale vključevati krepitev samoregulacije, podporo okolja ter prepoznavanje rizičnih skupin. Introduction: Adolescents, due to intense developmental changes, represent a high-risk group for developing internet addiction (IA) and gaming disorder (IGD). Prevalence varies across regions, and vulnerability is influenced by emotional dysregulation, impulsivity, ADHD, and unfavorable social conditions. Methods: For studies focusing on psychological factors, behavioral patterns, and neurobiological changes associated with excessive internet use among young people, we conducted a review of the scientific literature in the PubMed, CINAHL, and SAGE Journals databases using a predefined search strategy. Results: The most common motives for internet use are entertainment and social interaction. Excessive use is linked to poor coping strategies, cognitive rigidity, social withdrawal, depressive symptoms, sleep problems, and academic decline. Males and impulsive individuals are more at risk for IGD. Neurobiological studies reveal alterations in prefrontal, insular, temporal, and occipital regions, as well as dysfunctional connectivity among the DMN, ECN, DAN, and SN networks, affecting attention, inhibition, and emotion regulation. Discussion andConclusion: IA and IGD represent multidimensional issues involving psychological, social, and neurobiological factors. Changes in brain networks indicate weakened cognitive control, though some findings suggest possible compensatory mechanisms. Prevention and intervention efforts should focus on strengthening self-regulation, providing environmental support, and identifying high-risk groups. mladostniki internetna zasvojenost kognitivne funkcije možganske mreže pozornost adolescents internet addiction cognitive functions brain networks attention true false false [M.
