Personality changes are nearly universal in dementia patients, often negative, and linked to cognitive decline and neurological signs. This highlights the biological basis of personality shifts in Alzheimer

Area of Science:

  • Neuroscience
  • Psychiatry
  • Gerontology

Background:

  • Personality changes are common in dementia but require further investigation.
  • Understanding these changes is crucial for patient care and support.

Purpose of the Study:

  • To examine the prevalence and nature of personality change in dementia patients.
  • To explore the relationship between personality alterations and clinical factors.

Main Methods:

  • Assessed personality changes in 99 patients with Alzheimer type and multi-infarct dementia.
  • Utilized informant-rated inventories to compare pre- and post-dementia personality traits.

Main Results:

  • Personality change was almost universal and predominantly negative.
