Schizophrenia and neurogenesis: A stem cell approach.

Area of Science:

• Neuroscience
• Developmental Biology
• Psychiatry

Background:

• Schizophrenia (SCZ) pathogenesis may involve abnormal neurogenesis from embryonic Neural Stem Cells (NSCs).
• Neurogenesis extends beyond prenatal development, continuing through adolescence and adulthood.
• The onset of SCZ typically occurs in late adolescence or early adulthood.

Purpose of the Study:

• To review evidence linking altered postnatal neurogenesis to SCZ.
• To focus on the adolescent period and environmental risk factors.
• To explore the role of adult neurogenesis in psychosis development.

Main Methods:

• Literature review of recent research findings.
• Synthesis of studies on neurogenesis and SCZ.
• Analysis of critical developmental periods and environmental influences.

Main Results:

• Abnormal neurogenesis from Neural Stem Cells (NSCs) is implicated in SCZ.
• Postnatal neurogenesis, especially during adolescence, is a key period.
• Environmental factors during development may disrupt neurogenesis, increasing SCZ risk.

Conclusions:

• Altered postnatal neurogenesis is a potential contributor to SCZ.
• Adolescent neurodevelopmental changes are critical for understanding SCZ.
• Targeting neurogenesis may offer novel therapeutic and early intervention strategies for SCZ.
