This study found normal head size in schizophrenia patients, contrasting with some previous research. Cerebral volume reduction in schizophrenia is further explored in relation to head size.

Area of Science:

  • Neuroscience
  • Psychiatry
  • Anthropometry

Background:

  • Existing literature presents conflicting findings regarding head size in schizophrenia.
  • Substantial evidence indicates reduced cerebral volume in individuals with schizophrenia.
  • This study investigates extracranial head size as a potential correlate of cerebral changes.

Purpose of the Study:

  • To assess extracranial head size in patients diagnosed with schizophrenia.
  • To compare head size measurements between schizophrenia patients and healthy control subjects.
  • To elaborate on the relationship between brain size and head size in schizophrenia.

Main Methods:

  • Utilized standard anthropometric approaches to measure extracranial head size.
  • Assessed 44 patients diagnosed with schizophrenia.

Related Experiment Videos

  • Included 46 healthy control subjects for comparison.

    • Main Results:

    • Head size was found to be within normal ranges for patients with schizophrenia.
    • No significant reduction in extracranial head size was observed in the schizophrenia group.
    • The study provides data on the relationship between brain volume and head circumference.

    Conclusions:

    • Extracranial head size does not appear to be reduced in schizophrenia.
    • Findings suggest that observed cerebral volume reductions in schizophrenia are not mirrored by external head size.
    • Further research is needed to fully understand the complex relationship between brain morphology and head dimensions in psychiatric disorders.
