Area of Science:

  • Neuroscience
  • Psychiatry
  • Gerontology

Background:

  • Dementia is frequently accompanied by psychiatric symptoms.
  • These noncognitive symptoms, termed neuropsychiatric manifestations, pose challenges in dementia care.
  • A global approach to these symptoms may hinder effective management.

Purpose of the Study:

  • To advocate for the individual study of neuropsychiatric manifestations in dementia.
  • To provide a comprehensive review of delusions as a specific example of these phenomena.
  • To stimulate future research into the complexities of dementia-related psychiatric symptoms.

Main Methods:

  • Literature review focusing on delusions in dementia.
  • Discussion of nosology, phenomenology, and epidemiology.
  • Analysis of clinical characteristics, treatment options, and disease course.

Main Results:

  • Delusions are a significant noncognitive symptom complicating dementia.
  • Understanding the specific characteristics and course of delusions is crucial.
  • Current knowledge on treatment and epidemiology is synthesized.

Conclusions:

  • Individualized study of neuropsychiatric symptoms, like delusions, is essential for improved dementia care.
  • Further research is needed to elucidate the mechanisms and optimal management of delusions in dementia.
  • This review highlights the need for tailored approaches to psychiatric phenomena in dementia.
