Research has shown that internet addiction causes demonstrable changes in the brain, affecting areas related to attention, executive function, and emotion. Younger generations are more likely to use the internet and social media daily, while older generations are more likely to play outdoors. Internet addiction is defined as an impulse control disorder involving compulsive internet use. Warning signs include preoccupation, increased time online, failed control attempts, mood changes when reducing use, and relationship or work impacts. Causes may include family issues and social isolation. Side effects include mood shifts, neglecting responsibilities, and sleep and hygiene problems. Treatment involves assessment and counseling.
