Vascular Dementia

Vascular Dementia (VaD) is the second most common form of dementia, characterized by progressive cognitive decline caused by ischemic or hemorrhagic brain lesions. It results from impaired cerebral blood flow, leading to tissue hypoxia and neuronal death.

VaD is caused by cerebrovascular disease. Primary etiologies include:

• Ischemic Strokes: Large vessel occlusions or multiple small lacunar infarcts.


• Subcortical Ischemic Small Vessel Disease: Arteriolosclerosis affecting deep white matter.


• Cerebral Amyloid Angiopathy (CAA): Amyloid beta deposition weakening vessel walls.

Cerebrovascular pathology leads to focal or diffuse brain hypoperfusion. This causes localized tissue infarction or diffuse white matter demyelination (leukoaraiosis). The loss of oligodendrocyte-myelin units disrupts subcortical frontal-striatal circuits, resulting in executive dysfunction, slowed processing speed, and cognitive impairment.

• Prevalence: Accounts for 15% to 20% of all dementia cases in Western countries.
• Age: Incidence increases exponentially after age

• Gender: Slightly more prevalent in males due to a higher baseline risk of cardiovascular disease.

• Chronic hypertension
• Diabetes mellitus
• Hyperlipidemia
• Cigarette smoking
• Atrial fibrillation
• Advanced age

• Neurological: Focal motor deficits, hyperreflexia, unilateral Babinski sign.
• Cardiovascular: Irregular pulse (atrial fibrillation), carotid bruits, elevated blood pressure.
• Gait: Parkinsonian, magnetic, or short-stepped gait.

• A. Clinical Assessment: Cognitive batteries (MoCA, MMSE) showing executive deficits; Hachinski Ischemic Score >

• B. Laboratory Testing: Standard dementia panel to rule out reversible causes.
• C. Imaging Studies: Brain MRI or CT to identify structural vascular damage.
• D. Functional Tests: Neuropsychological testing.
• E. Biopsy Findings: Rarely performed; may show arteriolosclerosis or amyloid angiopathy.

• G. Differential Diagnosis: Alzheimer's disease, Lewy body dementia, Normal Pressure Hydrocephalus (NPH).

HbA1c
Type: Blood Test
Purpose: Screen for and monitor diabetes mellitus.
Expected Findings: Normal (<5.7%) or elevated (>=6.5%).
Interpretation: Elevated levels indicate poorly controlled diabetes, accelerating vascular damage. Lipid Panel
Type: Blood Test
Purpose: Evaluate cardiovascular and stroke risk.
Expected Findings: Elevated LDL, reduced HDL.
Interpretation: Dyslipidemia drives atherosclerosis, contributing to cerebral hypoperfusion.

Brain MRI (T2/FLAIR): Purpose: Evaluate ischemic burden. Findings: Multiple lacunar infarcts, cortical microbleeds, and confluent white matter hyperintensities. Clinical Importance: Key diagnostic tool to confirm cerebrovascular etiology.

• Alzheimer's Disease (AD): AD presents with gradual, insidious memory loss, whereas VaD often presents with stepwise decline and prominent executive dysfunction.
• Normal Pressure Hydrocephalus (NPH): NPH presents with a triad of wet, wobbly, and wacky (incontinence, gait apraxia, dementia), without focal stroke deficits.

• Aspiration pneumonia
• Recurrent stroke
• Severe depression
• Decubitus ulcers

• Short-term: Stable cognitive periods interrupted by sudden drops following ischemic events.
• Long-term: Poor; median survival is 3 to 5 years after diagnosis, typically due to myocardial infarction or recurrent stroke.

• Primary: Control of cardiovascular risk factors (hypertension, hyperlipidemia, smoking).
• Secondary: Dual antiplatelet therapy and statins post-stroke.
