Is There a Link Between Periodical Immoents and Cardy Rascalor Disease?

The jury is still out on this. There's enough to suggest that the p l m s are more than just innocent bystandards bystanders, but it's not clear yet. The association's not quite clear. We do see autonomic activations with p lm s. It does go up, and before the movement actually happens, and whether that movement results in an arousal or not. But we don't know all these nuwances yet. And so we think there's something there right now,. Is it that it's a direct relationship? Is it an indirect relationship?"
