Childhood psychosis in the preschool child.

Herrnstein et al. (1979) wrote up a small group of preschoolers who showed signs of psychosis. The kids were between three and five years old. The paper is a case series, so it simply describes each child rather than testing a treatment.

The authors showed that true psychotic symptoms can appear before age five. They also noted that these very early cases did better than the usual doom-and-gloom stories about childhood schizophrenia. In short, preschool psychosis is rare but real, and the future can be brighter than expected.

Hayes (1989) followed 16 school-aged kids with schizo-affective disorder and found they also improved faster than classic schizophrenia patients. This later case series backs the idea that early-onset cases can fare better.

Weissman-Fogel et al. (2015) flips the picture: they saw five teens first labeled psychotic who really had autism. The kids’ odd speech and play looked psychotic to adult eyes. The papers seem to clash, but the difference is age and diagnosis. J et al. warn us not to miss true preschool psychosis, while I et al. remind us not to stick the psychosis label on autism traits in older youth.

Castañe et al. (1993) tracked 39 early-onset cases and found diagnoses often changed as kids grew. This supports J’s plea to keep re-evaluating young children instead of locking in one scary label.

If you assess little ones for ABA, keep psychosis in the differential but don’t let it blind you to ASD or language delays. Document social, play, and language quirks carefully. Re-check the diagnosis every six to twelve months. When symptoms feel “odd,” bring in a child psychiatrist and request medical rule-outs before you plan intensive behavior programs. This cautious loop saves kids from wrong labels and wrong meds.
