The concept of vascular dementia is outdated and too broad. A new approach is needed to identify vascular cognitive impairment earlier for effective prevention.

Area of Science:

  • Neurology
  • Gerontology
  • Public Health

Background:

  • Vascular dementia is a leading cause of global cognitive impairment.
  • Current definitions and diagnostic criteria for vascular dementia lack consensus.
  • Existing approaches may identify patients too late for effective intervention.

Purpose of the Study:

  • To critically review the concept of vascular dementia.
  • To propose an alternative framework for understanding and managing vascular cognitive impairment.
  • To emphasize early identification and specific etiology-based prevention.

Main Methods:

  • Critical literature review of existing definitions and diagnostic criteria for vascular dementia.
  • Analysis of the limitations of current terminology ('vascular' and 'dementia').

  • Development of a proposed spectrum-based approach to vascular cognitive impairment.

    • Main Results:

    • The term 'vascular dementia' is considered obsolete due to its generic nature and late-stage identification.
    • 'Vascular' fails to specify etiological causes amenable to prevention.
    • 'Dementia' stage is often too advanced for significant preventive action.

    Conclusions:

    • A revised approach should encompass the full spectrum of vascular cognitive impairment, from preclinical stages to dementia.
    • Standardized neuropsychological measures are crucial for characterizing cognitive deficits.
    • Linking cognitive impairment to specific vascular causes is essential for targeted preventive strategies.
