Donald Trump has been so consistently out of control that it's time to start asking psychiatrists what's wrong with him, according to 'Morning Joe' co-host Mika Brzezinski.

The show's months-long feud with the Republican presidential nominee reached a new intensity on Monday as Brzezinski and Joe Scarborough bantered about whether Trump is a psychopath or a sociopath.

Trump has called Brzezinski, the daughter of Democratic national security adviser Zbigniew Brzezinski – who served in the Carter administration – said 'we've seen enough of him' to start asking a professional shrink about possible diagnoses.

'I think it's worth asking someone in the mental health community if this is someone you'd want to look at – are these signs of something that perhaps could lead to a diagnosis?' she asked.

Former Obama adviser David Plouffe said Sunday that Trump is a 'psychopath.'

Scarborough riffed on that idea, dragging the discussion into new territory.

'I don't think it's psychopath. Check up sociopath,' he recallde telling his daughter during a car ride.

'Now, psychopath – there are a lot of similar traits – except a psychopath chains people downstairs and eats them. ... A sociopath doesn't inflict physican pain and torture.'

'How about just narcissist and maybe some anxiety issue?' Brzezinski offered.

'Let's stop pretending we're dealing with someone who we can completely understand,' she added later. 'And when you see someone who you think has problems, you know it.'

The pile-on continued with former Ted Cruz spokesman Rick Tyler, who was fired for spreading a false rumor about Florida Sen. Marco Rubio disrespecting the Bible.

Tyler said every candidate for the presidency should be required to have a full mental health evaluation.

'We look at mental health much differently than we did in years past,' Tyler said.

'We don't require people to use firearms and serve in the military with mental health issues ... Why not? Why not a mental health evaluation?"

'Mental health is just like diabetes or any other physical health,' Brzezinski added. 'This is not something I'm making a joke about.'

Scarborough made light of the situation, however, saying that if his show brought a psychiatrist on as a guest, he wouldn't ask him to evaluate Trump by name.
