My son was very bright an A student and in Junior High just dramatically dropped to a D-F student who refused to do any school work. He seemed to stop developing normally and was not motivated. He was diagnosed with Schizophrenia at 22 years old. For years he kept saying he needed glasses but his eyesight was deemed fine by many visits to eye doctors. He said bright red lights bothered him as he drove at night, etc.. Thank you for your research.
