IMO the rise or fall of ones senses would come from the nessessity/desire of ones awarness as a whole. What I mean by that is just because I go blind
does not mean I will start to hear better, unless the need for me to hear better presents itself. Awarness as a whole can and will advance using any
and all senses if available if there is need for such advancement. A Sixth Sense then would certainly be in higher demand if one of the other five
were gone and a need to increase Awarness was also there.
I present for example the high possability that a Blind Man might be much more aware of Himself and the world around him than a man with all 5 senses
in tact, he would just experience and explain it non-visually.
Result: Sixth Sense within those who lack 1 or more of the first 5 is a Higher Probability, but stays equal in Certainty.
