AI has quickly become embedded in our everyday work, from drafting emails to synthesizing research and making decisions. In my roles as a medical doctor and business consultant, I talk to many corporate leaders who are focused on what that means for productivity. But recently, some have been asking a more fundamental question: What does AI use mean for the cognitive health of my workforce? Emerging research suggests this is not a theoretical concern. AI doesn’t just accelerate thinking – it often displaces it. When used passively, AI can weaken memory, judgment, learning, and confidence, and even diminish independent problem-solving. When used effectively, it can sharpen insight and free cognitive capacity for more complex work. The difference matters for corporate performance and workforce health. As demands intensify to involve AI in organizational processes and decision-making, companies risk building a workforce that looks productive but is less able to adapt, learn, and lead over time. Here are six steps leaders can take to protect and strengthen cognitive health in an AI‑enabled workforce: Treat cognitive health as a workplace health issue, not a skills gap Cognition isn’t just an individual capability. It’s a biological and psychological system that is shaped by daily work demands and the technologies we use, from writing to calculators and now, AI. But AI is more pervasive. Unlike earlier technologies, it steps directly into reasoning, synthesis, and judgment – not just execution. When employees routinely outsource thinking to AI, they may look productive while quietly losing mental and cognitive resilience. Leaders need to frame cognitive health the same way they frame burnout or ergonomics: as a key occupational health and safety matter, not just a personal concern. This ensures companies recognize and embed cognitive health into workplace policies, processes, trainings and design rather than simply expecting that employees cope better. Design work so AI s
