Annual review of clinical psychology·2014

Schizophrenia symptoms evolve over time, with negative symptoms worsening and leading to poorer long-term outcomes. This progression suggests active deterioration processes in early schizophrenia.

Area of Science:

  • Psychiatry
  • Clinical Psychology
  • Neuroscience

Background:

  • Understanding the longitudinal course of schizophrenia is crucial for testing illness models.
  • Subtyping patients using classical (DSM-III-R) and deficit/nondeficit (Schedule for the Deficit Syndrome) criteria provides a framework for analysis.

Observation:

  • During the initial 5 years of illness, schizophrenia subtypes showed moderate stability.
  • A drift towards disorganization and deficit subtypes was observed.
  • Positive symptoms remained stable, while negative symptoms significantly worsened.

Findings:

  • Worsening negative symptoms correlated with poorer functional outcomes approximately 15 years later.
  • These symptomatic changes suggest a pattern of deterioration in early schizophrenia.

  • The data align with existing literature on schizophrenia progression.

    • Implications:

    • The observed symptom trajectory suggests active deterioration processes in early manifest schizophrenia.
    • Theories of schizophrenic pathophysiology must account for these distinct patterns of symptom course.
    • This research highlights the importance of tracking symptom evolution for predicting long-term functional outcomes.
