Actually, there was a science fiction story that had that idea as a minor element. In Robert L. Forward's book Rocheworld, the astronauts take a drug to slow down their aging, for the interstellar trip. But one of the consequences of the drug is that it drops their intelligence to that of a child, while they are taking the drug. At the end of journey (IIRC it takes 40 years, during which they physically age about 10 years), they stop taking the drug and return to normal.
