Absolutely quite agree with this research. Early warning signs as described above in this article, were apparent in our son (such as delusional ideas or social difficulties particularly in his latter teen years), but remarkably these traits were not consistent (erratic) including his cognitive performance. He confused his teachers as he could out-perform the average students in one semester and then collapse the next one..... he himself was confused about his performance and abilities leading him to get very frustrated and increasing his inner -stress. His inconsistency was interpreted by some teachers as an attitude problem, yet we knew at home he was struggling and really trying his very best. We sought professional assessment with a clinical/educational psychologist (tested his cognitive abilities) only to prove that he was well above average thus fooling the assessor, and everyone else including himself, and then only later to loose his ability to function in full. Hence,without a proper diagnosis, he never received any educational support or even empathy leaving him in a stressful situation and eventually leading to full mental breakdown-psychosis. However, in our son's case he was always very social, highly sensitive and caring to others.....he difficulty dealing with more aggressive individuals-bullies in school. early diagnosis and a correct one might have alleviated his stress, hence avoiding the final blow of psychosis or permanent illness.
