Should Leaders Get Their Brains Scanned Before Rising to Power?

Dr. Daniel Amen thinks so, and he makes a bold case for examining the brains of global leaders such as Biden, Trump, Elon Musk, or prominent Brazilian figures. According to Amen, brain scans can reveal insights about brain health and mental well-being that go beyond what we see in public behaviour.

Dr. Amen has written more than 30 books on brain health and mental wellness. He argues that many mental health conditions should not be understood simply as problems “in the mind,” but also in relation to the physical functioning of the brain. Over his career, his clinics have collected more than 200,000 SPECT scans from people in over 150 countries. “I have seen more brains for psychiatry than anyone ever,” Amen said in an interview with Business Insider.

After examining thousands of brains, including those of psychopaths, artists, athletes, and public figures, Amen argues that understanding patterns of brain activity can offer valuable insights into behaviour and mental resilience. His work also emphasizes the possibility of improving brain health through lifestyle changes, focused self-talk, reducing negative influences, and reinforcing positive mental habits.

So how does he suggest we do it? Amen advises limiting constant exposure to negative news and instead talking to ourselves with kindness, clarity, and purpose. He encourages people to tell their brains exactly what they want in business, life, and personal goals. His argument is simple: the clearer we are about our priorities, the better we can direct our attention and behaviour toward achieving them.

Amen’s work is widely popular and influential, but his use of SPECT imaging in psychiatry remains controversial within the scientific community. Some neuroscientists argue that SPECT is not sufficiently validated as a diagnostic tool for individual psychiatric conditions. Critics caution that brain scans alone cannot capture the complexity of mental health, where behaviour, environment, personal history, and social factors also play critical roles.

There is an important nuance, however: Amen does not rely on brain scans alone. His clinics combine SPECT imaging with clinical history, symptoms, interviews, neuropsychological testing, and other information when assessing patients.

The scale of his work is impressive, but scale is not the same as scientific validation. A large number of scans can reveal patterns and demonstrate that a method has been extensively applied, but it does not by itself prove diagnostic accuracy. In medicine, validation also requires independent replication and evidence that a method can reliably improve diagnosis or treatment. That distinction does not diminish the potential value of Amen’s enormous dataset; rather, it leaves an important scientific question open for further research.

Despite the debate, Amen’s work has undoubtedly helped bring brain health into mainstream conversation. His practical emphasis on sleep, exercise, positive mental habits, self-reflection, and reducing harmful influences also raises a compelling question: if brain health affects judgment, behaviour, and decision-making, should we pay more attention to it when thinking about leadership?

The Takeaway

Whether world leaders should have their brains scanned is still up for debate, and yes, it is a catchy way to get your attention; however, Amen’s work reminds us of one important point: our brains are central to our thoughts, decisions, and overall well-being. Supporting brain health through lifestyle choices, healthy habits, self-reflection, and mental training is something everyone, leaders and citizens included, can benefit from.
