Now that he has won the presidency, why wouldnt he just pivot and become more normal? Why would he say things in public that are destructive to him and the nation? Why stir things up unnecessarily? The chaos and incoherence are much worse than expected.

These are some of the questions and concerns that have been raised about President Trump by persons who are untrained in how mental impairment can manifest. Indeed, the vast array of healthy human behaviors makes it difficult for the ordinary person to detect disability other than in the most obvious cases. Further, the more impaired the individual, the more likely he or she is to deny pathological behavior and insist that it is by choice. In our culture, mental impairment, unlike other medical illnesses, still connotes a moral failureleading to its denial or use only in epithets. Yet it can afflict anyone, it is nonpartisan, and we can identify it through objective criteria.

The Goldwater rule, which specifies that psychiatrists cannot diagnose a public figure without a face-to-face evaluation, has contributed to the lack of discourse and education about Mr. Trump. An expansion of the rule by the American Psychiatric Association in March 2017 further compromised that possibility. Frequently overlooked is the fact that the Goldwater rule itself occurs under the ethical mandate to contribute to the betterment of public health, for which a professional may share with the public his or her expertise about psychiatric issues in general. As a result, mental health issues are continually marginalized, and misconceptions persist. It is commonly assumed, for example, that mental impairment will cancel out responsibility, when this occurs only rarely. Also, mental illness does not imply violence: most mentally ill individuals are not violent, and most violent individuals are not mentally ill. What is important, therefore, is not the diagnosis but the combination of particular symptoms and the context whether observed in a clinical setting or from afar when assessing dangerousness.

In the case of President Trump, it has been apparent for some time that his inability or unwillingness to distinguish fact from fiction, rageful responses to criticism, lack of impulse control, and wanton disregard for the rule of law indicate emotional impairment rather than deliberate choice. Such signs and symptoms may be tolerable in a variety of settings, but not when this individual has command of the nuclear arsenal. Fitness for duty evaluations are a common practice among forensic psychiatrists and other mental health professionals, who follow a standard assessment procedure while applying it to the duty in question. Although military personnel who are responsible for relaying nuclear orders must undergo rigorous mental health and medical evaluations that assess fitness for duty, no such requirement exists for their commander-in-chief.

At a time of increasing conflict abroad and worsening divisions at home, we believe it is time to remedy this situation. The 25th Amendment to the U.S. Constitution, which addresses presidential disability and succession, has never been invoked to evaluate whether a standing president is fit to serve. However, Congress has the ability to act within its provisions to create an independent, impartial panel of investigators to evaluate Mr. Trumps fitness to fulfill the duties of the presidency. Congress can pass legislation to ensure that future presidential and vice-presidential candidates are evaluated by this professional panel before the general election, and that the sitting president and vice-president are assessed on an annual basis.

Our specific recommendations are as follows:

Congress must act immediately. Congressional inaction has brought us to a crisis point: the nuclear arsenal rests in the hands of a president who shows symptoms of serious mental instability, with indications that they will likely escalate. This is an urgent matter of national and international security. We call on our elected officials to heed the warnings of thousands of mental health professionals who have requested an emergency evaluation of Mr. Trump. The world as we know it could cease to exist in a momentary, angry outburst.
