Caffeine and Cognition, Statin Side Effects, and Nurses' Return to Hospitals

E374 • Feb 10, 2026 • 16 mins

In this episode, Dr. Chi-Ming Chow begins with a welcome and introduction before discussing the relationship between caffeinated beverages and cognitive health, examining their impact on dementia risk and cognitive performance. The conversation shifts to statin medications, focusing on cautionary labels, potential side effects, and the nocebo effect. The episode also covers the recent passing of Catherine O'Hara, shedding light on her medical condition. Dr. Chow concludes by exploring the factors influencing nurses' decisions to return to hospital work, offering insights into the current healthcare landscape.

Key Points

  • Moderate consumption of caffeinated coffee and tea is linked to a reduced risk of developing dementia, with caffeine playing a potential key role in these protective effects.
  • A pooled analysis of clinical trial data suggests that many adverse events listed on statin medication labels may not have sufficient evidence to support a causal relationship, potentially overstating the risks.
  • Adequate staffing levels, flexible scheduling, and better wages and benefits are significant factors that could entice registered nurses to return to hospital employment, addressing the current nursing retention crisis.
