ive been hearing about this for several months now and in almost all the cases their symptoms went away after seeing a doctor. the doctors didnt know what the hell was going on, but after they figured it out all these people had the same symptoms and same tics (the same symptoms/ticks the tic tokkers that they watch suffer from), they were able to clearly present that to the patient and eventually get them out of doing these tics.
it is real, but the sole reason for it is a desire to feel special or different, so they can stand out and get the same kind of attention they are seeing the people in tic tok videos receive.
the brain is a mysteriously powerful thing that can make us do weird shit when we are stressed out. in this case young people are stressed out about not being as special or getting the attention they are seeing all these people on the internet get. craziness, but i can see why its happening. we are not meant to have this instant, constant access to every human on the planet. it can make us better humans sure, but it can also lead to weird shit like this story.
