The Internet, mobile phones, and other similar tools are often necessary for the current functioning of both private life and business. During these two years of pandemic (2019-2021), Internet use, especially different games and mobile phones, were indispensable for the global population. Internet addiction is defined as a psychological dependence on the internet, regardless of the type of activity once logged on. Many studies have confirmed the correlation of stress, depression, and anxiety with internet addiction. It has also been proven that internet addiction, per se, increases the risk of depression, anxiety, and stress. Moreover, the COVID-19 pandemic has generated and promoted social isolation along with unmonitored and increased screen time, all of which are the main causes of internet addiction. The aim of this article is to give a short review of internet addiction research, terminology, and symptoms related to brain functioning.
