THE’excessive use of the Internetespecially through social networks, is profoundly influencing our mental and cognitive health. Recent scientific studies show how the compulsive consumption of low quality content – often characterized by sensationalism and superficiality – can lead to a reduction of gray matter in the prefrontal regions of the brain, responsible for crucial functions such as emotional regulation, memory and impulse control.
This phenomenon, defined as “brain rot” (or “brain rot”), was recently included by the Oxford Dictionary as word of the year, underlining the growing alarm around the negative effects of uncontrolled use of social media.
The trend, experts explain, is not a simple linguistic whim but a reality documented: our brain is increasingly vulnerable to the so-called doomscrollingor the endless consumption of news and content that is often alarmist or lacking in substance.

According to Michoel Moshel, a researcher at Macquarie University, this habit exploits the human brain’s natural tendency to look for new stimulia mechanism that in the past guaranteed survival but which today, in the digital age, fuels cycles of addiction. Features like infinite scrolling on social networks retain users glued to the screensespecially young people, with negative effects on attention and decision-making skills.
The problem is not limited to the individual sphere. Eduardo Fernández Jiménez, clinical psychologist, highlights how the massive consumption of variable content, such as notifications and continuous updates, is compromising sustained attentiona fundamental skill for learning and concentration. Consequences include difficulty completing complex tasks and a significant impact on memory and ability to socialize.
Research also shows that the neuroanatomical changes caused by Internet abuse are similar to those observed in substance addictions, such as alcohol and drugs. These effects are particularly serious in adolescents, as they coincide with critical stages of development, influencing identity formation and social skills.
To combat this phenomenon, experts recommend limiting the time spent online, preferring quality content and reducing features that encourage addiction. Activities such as sports, social gatherings and intentionally disconnecting from screens are essential for maintaining mental well-being and promoting balanced development, especially in younger generations.
