Non-PRO English to Spanish Art/Literary

In the early stages of Alzheimer's, the eyes have a wariness, a veil of fear. It's as if the person is standing at the edge of a fogbank, knowing that in time it will engulf him and there is no chance of outrunning it. I used to see my father's eyes simultaneously plead and hold firm. It would happen when a sentence broke off because he couldn't remember how to finish it. Or when he would say, "I have this condition-I keep forgetting things." He was on a wire, balancing on courage, with the dark waters of fear below, and he was using every bit of his strength to cling to that wire.
