Dementia patients with behavioral symptoms showed no significant differences in cognitive or functional decline compared to those without. Aberrant motor behavior correlated with advanced illness stage.

Area of Science:

  • Neurology
  • Geriatrics
  • Psychiatry

Background:

  • Behavioral and psychological symptoms are common in dementia.
  • Understanding the relationship between these symptoms and disease characteristics is crucial for patient management.

Purpose of the Study:

  • To investigate the association between behavioral symptoms in dementia and patient characteristics.
  • To analyze specific behaviors (aggression, psychosis, aberrant motor behavior) in relation to cognitive impairment, language deficits, illness stage, and functional disability.

Main Methods:

  • Retrospective study of 161 dementia patients.
  • Patients categorized into those with and without behavioral symptoms.
  • Subgroup analysis for patients with behavior changes at initial evaluation versus existing dementia.

  • Analysis of targeted behaviors against dementia-related domains: cognitive impairment, language impairment, CDR stage, and Rankin grades.

    • Main Results:

    • No significant differences in age, gender, cognitive impairment, language impairment, or disability between groups with and without behavioral symptoms.
    • A significant difference was observed in the stage of illness (CDR) between the two main groups (P=0.01).
    • Psychosis was the most frequent disturbed behavior; aberrant motor behavior showed a correlation with illness stage (P=0.04) in subgroups.

    Conclusions:

    • Behavioral symptoms in dementia do not appear to be strongly linked to cognitive or functional decline, except for a more advanced stage of illness.
    • Aberrant motor behavior may be an indicator of disease progression.
    • Further research is needed to elucidate the complex relationship between behavioral symptoms and dementia progression.
