We know how psychopathology may easily occur in adolescence. Not enough we know how a silent psychic disorder in infancy, that nobody noted, may be the origin of what come out in adolescence. The title of this book outlines how every psychopathology has its “adolescence”, that is the period in which it became manifest. The Author tells us about a patient in his second analysis. An early previous analysis allowed this patient being successful and having a good family, but a troubled period of his life made him to ask another analytical experience. The Author tells us about an adolescence in which he shows its remote origins in early infancy, in a narrative that may be easily read.
