When I was a medical student on my psychiatry rotation we had a patient who was a history professor at a local college. He was actually admitted to the hospital after reporting himself for molesting his neighbor’s children, but this was investigated and turned out to be impossible. Nonetheless, he was convinced he had done it, and was very impulsive and saddened by it (he would tearfully confess over and over). In the end, we imaged his brain and diagnosed him with frontotemporal dementia. The most strangest aspect was that you could look on rateaprofessor.com and see how he gradually changed over the semesters. I remember a comment saying that he came in on day one, told the class they would all get A’s, and left without coming back for weeks.
