I am new in the activities field but I recently had a success with one of our dementia residents. We were watching the Ziegfeld Follies on youtube (we have a really big screen in our Activity Room), then moved on to Fred Astaire and Ginger Rogers, all short clips. I was commenting on the beautiful and glamorous costumes, and the dancing. It really caught her attention, and she began commenting on what she was watching, with very appropriate commentary, like really tuned in - which is unusual for her. It somehow grabbed her, she latched on and could really talk about it on a reality level, and she thoroughly enjoyed it and told me afterwards it really brought back some old "friends" (I think she meant to say memories).
