Summary

Vascular dementia is a complex construct, not a distinct disorder. Vascular cognitive impairment (VCI) offers a clearer framework for diagnosing and treating cognitive deficits from ischemic brain lesions.

Geriatrie et psychologie neuropsychiatrie du vieillissement·2023

Area of Science:

  • Neurology
  • Neuroscience
  • Geriatrics

Context:

  • Vascular dementia is a poorly defined clinical construct with heterogeneous causes.
  • Current diagnostic criteria for vascular dementia are questionable due to mixed pathologies.
  • The overlap with Alzheimer's disease complicates diagnosis and treatment.

Purpose:

  • To introduce the concept of vascular cognitive impairment (VCI) as a more precise alternative to vascular dementia.
  • To clarify the relationship between ischemic brain lesions and cognitive dysfunction.
  • To emphasize early diagnosis and management of cognitive deficits linked to vascular factors.

Summary:

  • Vascular dementia lacks clear diagnostic criteria, leading to diagnostic challenges.
  • Vascular cognitive impairment (VCI) is proposed to better define cognitive issues from ischemic brain lesions.
  • VCI manifests with fronto-subcortical deficits, distinct from Alzheimer's disease.
  • Identifying and treating vascular risk factors is crucial for managing cognitive decline.

Impact:

  • VCI facilitates earlier diagnosis and intervention for cognitive impairment related to vascular issues.
  • Distinguishing VCI from Alzheimer's disease allows for more targeted treatments.
  • Management of vascular risk factors can prevent or slow cognitive decline, independent of or in conjunction with other pathologies.
