Vascular Cognitive Impairment (VCI) Characteristics

Cognitive Profile

The American Heart Association recommends recognizing vascular cognitive impairment (VCI) as a condition that especially affects executive function and processing speed, distinguishing it from other dementia types like Alzheimer's disease 1, 2, 3
The characteristic cognitive pattern of VCI involves a preponderance of executive dysfunction and slowed information processing, which includes executive function deficits, such as impaired ability to shift from one task to another, deficits in working memory, and problems with initiation, inhibition, planning, organization, judgment, and problem-solving 1, 2, 3
Processing speed is characteristically slowed in VCI, making timed executive function tests especially sensitive for detecting the condition 1, 4
Attention deficits are commonly affected alongside executive function and processing speed in VCI 2, 3

The American Academy of Neurology suggests that neuropsychological testing should specifically target executive function and processing speed when VCI is suspected, including timed executive function tests and evaluation of attention, processing speed, executive functions, learning and memory, and visuospatial abilities 1, 5
Brief screening tools like the Montreal Cognitive Assessment (MoCA) with phonemic fluency and Trail Making Test are recommended for assessing VCI 1

The Alzheimer's Association notes that unlike Alzheimer's disease, which typically presents with amnestic deficits as the initial and most prominent feature, VCI characteristically presents with executive dysfunction and slowed processing as the primary deficits 1, 6
