I have read the book (I recently received it from an elderly friend who hoarded books--I picked through about $20,000 worth of books and chose several hundred dollars worth), and it started off interesting, to hear of her personal experience of the stroke and its accompanying mind-states. She seems to have fought her way through various delusions, but not with any more success than other examples cited here. Yes, she is/was a neuroscientist. She also proudly proclaims that she tells her bowels "Good job! I am so thankful that you do exactly what you are meant to do!" every time she takes a dump, and concluded the book with some painfully New Age-y exhortations which gave me the same urge to roll around frothing at the mouth that I often experienced with clearly delusional Christian preachers in church.

The Amazon page for the book doesn't describe her getting any of the sort of very specific delusions described in the OP though, just general debilitation and paradoxical feelings of euphoria.
