There's no doubt that toys that allow kids to fidget can benefit kids with autism. Occupational therapists often use sensory toys like tactile discs, Koosh balls and even putties or clays to soothe kids who have sensory-processing issues. Similarly, research has shown that movement can help kids with ADHD to focus. A 2015 study published in the Journal of Abnormal Child Psychology by Rapport and his colleagues looked at 8- to 12-year-old kids with ADHD. The researchers found that those who participated in gross motor activity — meaning the movement of limbs or large parts of the body — performed better than those who sat still during tasks involving working memory, which is a type of memory used for processing incoming information. Exercise has also been proven to be helpful for kids with ADHD.

But without studies that specifically look at fidget spinners, it's impossible to say for sure whether the devices could help kids with ADHD, Rapport told Live Science. He conjectured that the little handheld toys are not likely to help much. They don't require gross body movement, he said, which is what appears to be responsible for increasing activity in the frontal and prefrontal brain areas that are responsible for sustaining attention. The spinners are also visually distracting, and so they could pull a child's attention away from the chalkboard or teacher, Rapport said.
