Adolescent stress exposure in rats can lead to schizophrenia-like deficits in adulthood. Impaired stress control exacerbates these effects, highlighting adolescence as a critical period for psychosis vulnerability.

Area of Science:

  • Neuroscience
  • Psychiatry
  • Developmental Psychology

Background:

  • Adolescence is a critical neurodevelopmental period.
  • Heightened stress responsivity in adolescence precedes psychosis onset in schizophrenia.
  • Early life stress is a risk factor for psychiatric disorders.

Purpose of the Study:

  • To investigate the long-term effects of adolescent stressors on adult behavior in rats.
  • To examine the role of prefrontal cortex-mediated stress control in schizophrenia-like deficits.
  • To identify potential early markers for schizophrenia vulnerability.

Main Methods:

  • Induction of multiple stressors in adolescent rats.
  • Lesioning of the prelimbic prefrontal cortex to impair stress control.

  • Behavioral and physiological assessments in adult rats.

    • Main Results:

    • Adolescent stress exposure resulted in adult deficits analogous to schizophrenia.
    • Impaired stress control in adolescence led to stress-induced deficits at subthreshold levels in adulthood.
    • These findings suggest a critical role for adolescent stress exposure and regulation in psychosis development.

    Conclusions:

    • Adolescent stress and impaired stress control can trigger schizophrenia-like profiles in adulthood.
    • Identifying early markers of stress hyper-responsivity may aid in preventing psychosis.
    • Targeting stress-related pathways during adolescence could be a therapeutic strategy.
