I see a lot of people blaming tiktok and “brain rot” content for the increasing ADHD diagnoses, but I think its a matter of better detection, similar to how OCD and autism diagnosis have increased too.
Also as someone with ADHD, it feels like shit that it could be “my fault” or that I have brainrot.
Sure, a person who gets shot in the head and loses part of their prefrontal cortex functionality could have “type 2 ADHD”, and I suppose that if you otherwise similarly physically harm your brain using some chemicals in the same way that excessive sugar harms your pancreas you could develop the same condition. In fact I think meth usage would probably create a similar condition in the brain since long use of it causes you to be unable to produce serotonin/dopamine in the appropriate levels. But I seriously doubt that watching videos on your phone can cause it, any more than it can cause diabetes.
