I'm a neurologist, and I don't think AI will make people dumber. Here's how to keep your brain sharp.

In a world increasingly shaped by artificial intelligence, maintaining a sharp mind is crucial. Dr. Majid Fotuhi, a neurologist and adjunct professor at Johns Hopkins University, emphasizes the importance of neuroplasticity—the brain's remarkable ability to adapt and rewire itself at any age. This adaptability is vital as we navigate the challenges posed by modern technology. The cortex and hippocampus play significant roles in our cognitive functions, such as reading, writing, and problem-solving. These areas are highly malleable, influenced by various factors like cultural experiences and mental exercises. Dr. Fotuhi explains that our brains today differ substantially from those of our ancestors, as we face unique challenges and information overloads. Despite concerns about AI making us less capable, Dr. Fotuhi argues that engaging with AI can stimulate our brains. The influx of information requires us to critically assess what is true, relevant, and useful. While we may not perform mental calculations as often, we are tasked with processing more complex data than previous generations. To keep your brain active, Dr. Fotuhi recommends dedicating 20 to 30 minutes daily to cognitive exercises. These do not always need to be structured; everyday activities can serve as brain workouts. When reading the news, for instance, delve deeper into the content. If an article discusses a bombing, research the details—who was involved, what was affected, and the broader implications. Memory exercises can also be effective. Dr. Fotuhi suggests trying to memorize names or numbers daily, which strengthens your memory. He avoids relying on GPS for navigation, opting instead to strengthen his spatial awareness. Engaging in hobbies that require interaction and concentration, like dancing or sports, can also enhance brain function. Ultimately, Dr. Fotuhi believes that enjoying what you do is key to cognitive health. While there are many ways to challenge your brain—beyond traditional puzzles—it's essential to balance AI usage with personal effort. By writing emails and responses yourself, rather than solely depending on AI, you keep your mind sharp and engaged. Remember, with the right habits, you can harness the positive aspects of AI while maintaining your cognitive independence.
