Agrees!
However I think the American Mental Health professionals can also form an opinion, and as an organization voice their concerns (not as individuals) in a way that would be useful to the American people and the world generally. Even if they simply recommend that Trump attends a psychiatric assessment.
Very doubtful the AMH even as group would voice ANY opinion about ANYBODY let alone POTUS
Again a individual doctor would not make diagnosis (particular mental diagnosis) without examination of the patient
That holds true for a group of doctors
The AMH can and does make medical recommendations for overall health of the population
