The articles presented here are the results of the authors working together as a group for many years. Over the years, a common reflection has been elaborated, in particular on autism. That is the reflection we propose to the readers through four clinical studies. In this way, we want to participate in the research of such a particular field of psychoanalysis and psychotherapy with suffering children and teenagers. In the first study, through the description of a few sessions related to a clinical study of children psychotherapy, Attilia Lanteri tries to highlight the richness of the internal mental world of a psychotic subject. In the second study, Laura Pasero describes the beginning of a psychoanalytic psychotherapy with a boy with a pervasive development disorder. It highlights the steps through which the therapeutic relationship is transformed and develops some sort of communication from a first confused and fragmented language. In the third case, Paolo Vassallo through a clinical study, wants to highlight how psychoanalytically inspired psychotherapy can be used with autistic ‘high functioning’ autistic subjects and how much these patients can benefit from it. Finally, Nicole Geblesco describes the care pathway with a girl suffering from autism and the exploration of her interior world which, instead of being an empty box, shows itself to be a casket full of symbols, the dynamism of which is loaded with vital forces but encapsulated in a cryptic language waiting to be decoded.
