When stroke risk factors quietly affect thinking — detection and prevention
Vascular cognitive impairment (VCI) spans the spectrum from mild executive slowing to vascular dementia and is the second most common cause of dementia after Alzheimer disease — yet it is also the most preventable, because its drivers are the same vascular risk factors that cause stroke. Dr. Jitendra Prasad Yadav (NMC 8029), whose practice bridges stroke medicine and cognitive neurology at Kathmandu Neurology Clinic & Cognitive Center, evaluates patients with memory or slowness concerns specifically for vascular contributions: hypertension, diabetes, atrial fibrillation, prior silent infarcts and white-matter disease.

Unlike the typical amnestic profile of early Alzheimer disease, VCI classically shows executive dysfunction — slowed processing speed, difficulty planning, reduced verbal fluency — often with a stepwise or fluctuating course linked to cerebrovascular events, though insidious decline from small-vessel disease is equally common. Gait change, urinary symptoms and mood disturbance frequently accompany it.
Assessment combines structured cognitive testing (MoCA with executive subtests), informant history, vascular risk-factor inventory, and MRI when findings would change management — looking for infarcts, white-matter hyperintensities and microbleeds. Reversible contributors (B12, thyroid, sleep apnea, medication effects, depression) are screened in parallel. The therapeutic emphasis is aggressive vascular risk optimization: blood-pressure control is the single most powerful intervention, followed by glycaemic control, lipid management, anticoagulation for atrial fibrillation, smoking cessation, exercise and hearing correction. Cognitive stimulants have limited role; structured follow-up monitors trajectory.
