> “If anyone is saying that this is due to depression and anxiety, they have no basis for that, and data suggest it might be the other direction,” Joanna Hellmuth, a neurologist at UC San Francisco, told me. Paywalled on the article you link, so maybe it's explained more in detail there, but what does "the other direction" mean? Is this doctor claiming that depression/anxiety would protect against it? Or that it causes "the other direction" of symptoms e.g. happiness, relaxation? Neither of those seem to track with other reporting I've seen.
