I agree with you 100%. I am a speech/language pathologist and I believe (and have believed since I watched his speech on the morning after his inauguration) that Trump shows a significant language disorder. Further, I have reviewed many, many of his interviews and conversations over the years and I feel very strongly that his decline is progressive. I am also the wife of a clinical psychologist (in practice for more than 30 years) who believes that Trump shows both a cognitive decline/possible dementia AND a serious personality disorder. He is a member of Duty to Warn. If you’re so inclined, I have an article here on Medium about Trump’s language disorder; https://medium.com/@momshieb/i-know-whats-wrong-with-trump-5325a6aa8ae
