I think there's more to this than we understand. I had a trainer who was a handwriting analysis expert. You really would not believe what he could see with a couple of sentences written on a napkin. I saw him read people a dozen times to a jaw-dropping level. You just wouldn't believe it. If handwriting analysis can reveal an unbelievable amount of information about a person's character, desires, psyche, even past physical injuries... perhaps it could be true that cursive COULD do something for the brain, and learning specific ways of writing cursive could develop different attributes. Not the craziest thing I've heard that turned out to be true. I have a book called "Your Handwriting Can Change Your Life" by Vimala Rodgers. Interesting, is all I'm saying.
