This is amazing. I'm currently studying neuroscience at university, and I'm watching videos on RU-vid before we cover Bipolar Disorder (which I suffer from) on Wednesday.
I'm wondering to what extent cluster 2 correlates with BSNIP's biotype 1 and cluster 1 with biotype 2. 13% of cluster 2 having an anxiety disorder, when we consider that we are talking about young people, to me sounds like a very low proportion - so I would guess that they are very nonreactive and insensitive to stimuli generally, while cluster 1 are more acutely aware of their surroundings and/or internal cognitive processes, as seen in more florid presentations along the schizophrenia-bipolar spectrum, like what we see in mania and mixed affective states.
