[The schizophrenic's chilhood]

Area of Science:

• Neuroscience
• Psychiatry
• Developmental Psychology

Background:

• Schizophrenia typically emerges in late adolescence or early adulthood.
• Epidemiological studies suggest rare childhood-onset forms of schizophrenia exist.
• These early-onset forms present distinct clinical phenotypes.

Purpose of the Study:

• To explore the developmental trajectory of schizophrenia from infancy to adolescence.
• To investigate the neurobiological and environmental factors contributing to early-onset schizophrenia.
• To present a neuroscientific perspective on the origins of schizophrenia.

Main Methods:

• Review of recent neuroimaging studies.
• Analysis of genetic research findings.
• Integration of developmental psychology and epidemiological data.

Main Results:

• Two distinct early-onset schizophrenia phenotypes identified: one around age 9, another around age 15.
• Both forms are associated with profound, lasting alterations in neurocognitive development.
• The origins of these alterations likely trace back to prenatal or early infancy periods.

Conclusions:

• Childhood-onset schizophrenia represents a significant deviation in neurodevelopmental trajectories.
• Understanding prenatal and infant factors is crucial for deciphering schizophrenia's etiology.
• Further research integrating neuroimaging and genetics is needed to elucidate early schizophrenia development.
