Excellent points, Poseidon. I'm not completely sold on the physical damage being the sole cause of his amnesia, since we see that he was also suffering a massive psychotic break at the time. The chapter spent inside his mind, with the two Kanekis embracing each other and resolving to sleep for a while, makes me wonder if much of it is psychological in nature. It would also fit with how reluctant Haise has been to pursue anything about his past all this time.

So essentially, it could be purely a matter of physical damage, purely a matter of psychological trauma, or a combination of both.
