I know producers of Star Trek First Contact (or was it the Okudas in one of their reference books) speculated that the reason Cochrane in First Contact looked so much older and physically different that the Cochrane encountered by Kirk in TOS "Metamorphosis" was because of radiation poisoning...
Could another possibility be that the Companion had encountered a younger human explorer who had perished in some way before she met Cochrane, and when she encountered the elderly, dying Cochrane, she transferred his consciousness into the other human body, to save Cochrane's life? It certainly isn't out of the realm of the Trek universe, and we saw that the Companion itself was able to transfer itself into the body of Nancy Hedford (sp?)...
Might also explain why Kirk and his landing party didn't recognize someone as famous as Cochrane, and why they were confused when he identified himself finally as Cochrane ... I just never really bought the radiation reasoning ... and yeah, I know we can just explain it away as (different actors, different writers, etc.)
