Emotional appeal as a persuasive tactic is fully evident in a new Chevrolet ad. Grandma has dementia, but a Chevy helps her remember.

In the video, a granddaughter takes grandma for a ride in her 1972 Chevy Suburban, tarped in the garage for who knows how long but running flawlessly. During the five-minute commercial, we hear John Denver playing on the car’s ill-fated 8-track tape.

Grandma awakens during the journey, remembering the old days and speaking in complete, cogent sentences. She returns to her family, seemingly fully recovered.

Chevrolet’s head of marketing said the ad was created “with help” from the Alzheimer’s Association:

We talked a lot about reminiscence therapy—not that it's a cure or a solve, but the power of music, the power of memories are things that can enable the person going through it to feel more comfortable. And the people that are the caregivers that are surrounding them, to also feel more comfortable.

A clinical chaplain tells me it’s not uncommon for people with dementia to get reoriented in familiar situations (like listening to “Sunshine on My Shoulders”), although the extremes in this case are unlikely. Chevy tries to avoid this problem by calling it a “good day,” but we might consider it a “miraculous day.” A Yahoo! article also points out, “It’s worth noting, though, that people with Alzheimer’s may not recall short-term memories, as the ad’s grandmother does when she realizes she’s due back for Christmas dinner.”

I wonder how folks at the Alzheimer’s Association feel about the ad. They might worry about false expectations for people with dementia. But I get it: It’s a fantasy. That’s what Christmas—or advertisements—are often about. I teared up when grandma and grandpa reunited too.

Maybe Chevy can change the title. The generic, “A Holiday to Remember,” appeases those who don’t celebrate Christmas. But the lights, red and green decorations, pinecone wreath, and that Lands’ End sweater all scream Christmas. Even grandma says at the end, “Merry Christmas.”
