Childhood schizotypal features vs. high-functioning autism spectrum disorder: Developmental overlaps and phenomenological differences

Although autism spectrum disorder and schizophrenia have allegedly different onset timelines (e.g. in early years of life vs adolescence/early adulthood), there is nonetheless a diagnostic grey-zone along developmental stages, in which overlapping clinical features related to social impairment and oddity could impact on the differential diagnosis between childhood schizotypal features and high-functioning autism spectrum disorder. A phenomenological perspective may be helpful for the purpose of timely differential diagnosis also in developmental years.
