Background:

  • Capgras symptom involves the delusion that a familiar person has been replaced by an imposter.
  • This symptom has been anecdotally linked to violent behavior.

Purpose of the Study:

  • To report two cases of schizophrenia with paranoid type where Capgras delusion was associated with parricide.
  • To highlight the role of non-adherence in the development of violent behavior in these cases.

Main Methods:

  • Case report of two male patients diagnosed with schizophrenia, paranoid type.
  • Clinical observation focusing on the presence of Capgras delusion and history of non-adherence to treatment.

Main Results:

  • Both patients exhibited Capgras delusion.
  • Parricide occurred in both cases, strongly linked to the delusion.
  • Non-adherence to antipsychotic medication was a critical factor in the exacerbation of symptoms and subsequent violence.

Conclusions:

  • Capgras delusion can be associated with severe violent acts, including parricide, in patients with schizophrenia.
