Rochelle Youner, who lives at the Hebrew Home at Riverdale, a nursing home in the Bronx, walked up to a kiosk in a common area of the home’s first floor and pressed a button below a small icon depicting a baseball glove.

“That’s the real stuff — that’s a mitt, all right,” Ms. Youner, 80, said, smelling the leathery fragrance emitted from the kiosk, which attempts to bring the ballpark, or at least the smell of it, to the residents.

Many of the Hebrew Home’s residents were born and raised in the Bronx and are lifelong fans of the Yankees, with memories of visiting Yankee Stadium stretching back to the eras of Mantle and DiMaggio, and even earlier to Gehrig and Ruth.

But many of these older fans also suffer age-related memory loss. So the home, which often finds seasonal pegs for its reminiscence therapy programs, has timed its latest program to opening day at Yankee Stadium on Monday by erecting the kiosk with the therapeutic goal of recreating the distinctive smell of the ballpark.
