Artificial Intelligence (AI) has radically changed not only how we work, but also how we communicate and even think. And that's not all, surprisingly, we are still in a kind of embryonic stage of AI. Yet this technology is already revolutionizing every sector of society, with an impact comparable, if not greater, than the discovery of electricity.
From virtual assistants to algorithms that predict our preferences, AI has brought unprecedented convenience to everything we do. However, this ease comes with ambiguity. So we must ask: Is this convenience exacting a high price on our brain health?
Recent research and clinical observations suggest that excessive dependence on AI may be contributing to an increase in cognitive disorders, especially among young and middle-aged adults. What’s alarming is not just the "here and now," but the near future: what might neuroplasticity do to these "underused" brains? Let’s reflect on this new aggravating factor in the global spread of dementia.
AI tools are built to simplify tasks across professional fields. But when we stop using our brains to solve problems, make decisions, or recall information, we fall into a state of cognitive passivity.
This phenomenon, known as cognitive offloading, occurs when we begin to delegate mental tasks to devices and software. While this habit can be helpful in certain contexts, its constant use may lead to the atrophy of brain regions responsible for memory, attention, and reasoning.
Neuroscience has already confirmed the "use it or lose it" principle regarding brain function. That is, with the help of AI, fewer people memorize phone numbers, addresses, or even basic information. Voice assistants answer questions in seconds, search engines complete our thoughts, and some apps make decisions for us.
This ease of use fosters mental indolence in those who overuse AI tools. This tendency has led some experts to coin the term "digital dementia," a cognitive decline linked to excessive use of digital devices and technological dependence.
Symptoms include memory lapses, attention deficits, difficulty solving problems, and, in more serious cases, early signs of mild cognitive impairment (MCI).
Beyond memory and attention, AI may also negatively affect emotional intelligence (EQ). By living in algorithmic bubbles and interacting more with machines than people in our daily lives, we diminish the complexity of human relationships. This growing trend may affect brain areas responsible for empathy and emotional self-regulation.
In children and adolescents, for example, the impact can be even deeper, potentially influencing neurological development in lasting ways. Imagine these individuals years from now, with brains whose status quo has been reshaped by technological dependence. That’s neuroplasticity in action.
Better not to imagine what might happen in the brains of future generations, the "offspring" of today’s mentally lazy...
The fact is, AI feeds our brains with a constant flow of stimuli: notifications, messages, personalized content, short videos, infinite suggestions. This information overload leads to cognitive overload, which can cause stress, anxiety, insomnia, and even mental exhaustion.
The term neurological burnout is already in use, describing a condition in which the brain loses its ability to sustain deep focus and critical thinking skills that are essential for long-term cognitive health.
At MCI and Beyond, we advocate for a more mindful relationship with technology. Here are some simple strategies to protect your brain:
Artificial intelligence is not—and never will be—the villain of this story. As the saying goes, "used wisely, it will work." The real problem lies in how often and how dependently we use it. Excessive dependence can impair the functions that define our humanity: memory, attention, creativity, and emotion.
We believe technology should be a partner in mental health, not a substitute that enslaves the human brain. This magnificent machine in our skull is unique and irreplaceable. Let’s keep it that way.
