About Dr. Gartner and Dr. Segal
Donald Trump’s Mental Health Under Expert Analysis
Each week, leading psychologists Dr. John Gartner and Dr. Harry Segal, along with distinguished guest experts, conduct a thorough analysis of Donald Trump’s psychological state. Their sessions explore the former president’s cognitive decline, malignant narcissism, and the growing threat his mental health poses to democratic stability and global security.
Dr. John Gartner, a former part-time assistant professor of psychiatry at Johns Hopkins University Medical School, is widely recognized for his expertise in personality disorders. He is the founder of Duty To Warn, an organization composed of mental health professionals committed to raising public awareness about the psychological dangers associated with Trump’s behavior. Through Duty To Warn, Gartner has helped unify hundreds of psychologists, psychiatrists, and other experts who believe that Trump’s psychopathology presents a clear and present danger to society.
Dr. Harry Segal, a senior lecturer in psychology at Cornell University, brings decades of academic and clinical expertise in psychoanalysis, trauma psychology, and political behavior. Together, Gartner and Segal offer a deeply informed, evidence-based perspective on Trump’s psychological makeup, setting their analysis apart from mere political commentary.
The focus of their sessions is on identifying and documenting signs of progressive cognitive decline and malignant narcissism — two deeply concerning patterns for anyone in a position of power. According to their findings, Trump exhibits classic features of narcissistic personality disorder, including an insatiable need for admiration, profound lack of empathy, a tendency to dehumanize others, and persistent grandiosity. They also point to indications of cognitive slippage, such as frequent incoherence, difficulty processing complex information, memory lapses, and impaired judgment.
Experts warn that these psychological traits, when combined, create a dangerously volatile leader — one who prioritizes personal ego over the national interest, refuses accountability, and is willing to undermine democratic institutions to preserve his image and authority. Dr. Gartner and Dr. Segal argue that Trump’s mental health decline is not merely a private concern but a public emergency, warranting urgent attention from policymakers, citizens, and the global community.
Their weekly sessions are rooted in professional ethical standards, such as the duty to warn principle, which obliges mental health professionals to speak out when a public figure poses a risk to others. Although some critics argue against diagnosing from a distance, Gartner and Segal emphasize that observing dangerous patterns based on public behavior, speeches, and documented actions is both responsible and necessary in extraordinary circumstances.
Beyond Trump himself, Gartner and Segal’s analysis serves as a broader warning about the dangers of authoritarian personalities in positions of power. They stress the need for psychological evaluations to become a standard part of vetting leaders, particularly when signs of severe narcissism, sociopathy, or cognitive deterioration are evident.
Through their efforts, Duty To Warn has become a leading voice advocating for the intersection of psychology and public policy. Their work reminds citizens that mental health, especially in leadership, is a critical component of national security.
The ongoing sessions led by Dr. Gartner and Dr. Segal not only deepen public understanding of Donald Trump’s mental health, but also encourage vital conversations about leadership standards, psychological resilience, and democratic preservation. Their commitment to clinical integrity, transparency, and civic responsibility makes their analysis an essential resource for anyone seeking to understand the deeper forces shaping today’s political landscape.
