Area of Science:

  • Geriatric Psychiatry
  • Neuropsychology
  • Clinical Psychology

Background:

  • Delusional jealousy is a significant factor in violence.
  • It can manifest in patients with dementia.
  • Prevalence and characteristics in dementia are not well-understood.

Purpose of the Study:

  • To determine the frequency of delusional jealousy in demented patients.
  • To characterize delusional jealousy in this population.

Main Methods:

  • A sample of 133 demented patients from a geropsychiatric ward was analyzed.
  • Patients with and without delusional jealousy were compared on demographics and psychotic symptoms.

Main Results:

  • Delusional jealousy was present in 15.8% of patients (21/133).
  • It occurred across various dementia types.
  • No significant differences in age, gender, or cognitive scores were found between groups.
  • All patients with delusional jealousy exhibited other psychotic symptoms.

Conclusions:

  • Delusional jealousy is a common comorbidity in dementia.
  • Underlying psychobiological factors may differ from cognitive decline.
  • Further research into the development of delusional jealousy in dementia is warranted.
