Physical therapy is its own field. It varies state to state but usually an accredited physical therapy course is a undergraduate degree. Commonly with the title "Doctor of Physical Therapy". Here's the list of US accredited courses.

or an MBA

What?

Master of Business Administration? After a Neuroscience PhD?

Why?

like a manager or officer in a memory nursing home business.

Nursing is a different course. Manager or officer doesn't require a neuroscience PhD.

How about counseling neurological challenged folks?

Counselling is a different course. It also doesn't require a neuroscience PhD.

Or helping to administer a trial of a MS/dementia/etc medicine?

Yep. That's what a postdoc would do. See the above shit hours and shit salary given the debt you're likely to have after 26 years of schooling.

It’s becoming obvious that you have little education and have even less knowledge about professional career paths.

Oh the irony.

So let me sp’lain something to you: Getting an undergraduate degree in neuroscience does not necessarily require continuing to study neuroscience to make profitable use of the background.

According to the article this individual "ditched being a scientist". A scientist is a researcher, not a nurse or office or business administrator.
