I've been following this closely. There's no real data on the following: - Is this happening in other countries? I cannot find really any established diagnoses outside of the US (though some countries have CDC-like pages on it). - What is the gender breakdown? - What is the age breakdown? (mean, median, SD) - What is the geo breakdown? (city vs rural, major geo areas)
