Abstract

Vascular dementia (VaD) accounted for 13–35% of all incident dementia cases and is the second cause of dementia. The prevalence of VaD is 1–2.4% in person 65 years and over, and incidence rate is 1.5–39 cases per 1000 person-years in age over 65, and increase in older groups.
Subtypes of VaD:
1. Post-stroke dementia
  • strategic infarct dementia
  • multi-infarct dementia
  • dementia after intracerebral haemorrhage
    2. Subcortical vascular dementia
  • ischaemic white matter lesions (leukoaraiosis)
  • lacunar infarcts
    3. Alzheimer’s disease (AD) + vascular dementia.
    Executive dysfunctions (planning, organizing, slowed information processing, inattention) are the most frequent in patients with VaD. The memory deficits are mild and do not predominate. Patients with VaD more frequently exhibit fluctuations and “patchy deficits” in cognitive functions than patients with AD. Language dysfunction in VaD is characterised by greater deficits on measures of verbal fluency. Patients exhibit some elements of motor aphasia and relatively good preserved understanding of verbal language, and also significantly more perseverations than patients with AD.
    The spectrum of vascular brain changes visualised by structural and functional brain imaging in VaD include: lacunar infarcts, white matter lesions, deep grey matter lesions, strategic infarct. MRI and SPECT are preferable methods for detection brain changes in VaD.
