Internet addiction, or excessive Internet use, is characterized by excessive or poorly controlled preoccupations, urges, or behaviors regarding computer use and Internet access that lead to impairment or distress. It is not currently recognized as a disorder in the DSM-IV, but has been proposed for inclusion in the DSM-V. Research indicates prevalence rates between 1.5% and 8.2% in the US and Europe, with high comorbidity with psychiatric disorders such as affective disorders, anxiety disorders, and ADHD. Factors predictive of problematic Internet use include personality traits, parenting, alcohol use, and social anxiety. Despite the lack of a formal diagnosis, there is growing evidence that Internet addiction may be a distinct disorder. Neuroimaging studies suggest that Internet addiction shares neurobiological mechanisms with substance use disorders. Genetic factors may also play a role, with some studies indicating a link between Internet addiction and genetic polymorphisms. Cognitive factors such as decision-making deficits and prepotent response inhibition are associated with Internet addiction. Treatment options are limited, with psychosocial approaches being the mainstay, though no evidence-based treatments are currently available. There is also evidence of comorbidity with other disorders such as OCD and ADHD, and some pharmacological treatments have shown promise. However, due to methodological limitations, the exact pathophysiology and effective treatments for Internet addiction remain unclear. The condition is associated with various health hazards, including sleep disturbances and social problems. Overall, Internet addiction is a complex issue with significant implications for mental health and well-being.Internet addiction, or excessive Internet use, is characterized by excessive or poorly controlled preoccupations, urges, or behaviors regarding computer use and Internet access that lead to impairment or distress.
