Cerebral small vessel diseases: cerebral microangiopathies.
Level 5 - mechanism / opinion, no new human data
Narrative review without systematic search or meta-analytic methodology
PubMed 15791150 · doi:10.1097/01.wco.0000162861.26971.03
What was done
This narrative review synthesized literature on the pathophysiology, genetics, neuroimaging diagnostic tools, and therapeutic options across acquired and hereditary cerebral small vessel diseases, including degenerative microangiopathy, CADASIL, retinocerebral vasculopathies (such as Susac's syndrome), cerebral amyloid angiopathy, Fabry's disease, and mitochondrial cytopathies.
What was found
The abstract reports no numerical results or effect sizes. It qualitatively summarizes that white matter tract disruption contributes to cognitive decline in acquired small vessel disease, clinical trials indicate potential benefit from acetylcholinesterase inhibitors, CADASIL results from Notch3 mutations affecting vascular mural cells, and cerebral amyloid angiopathy predisposes to lobar hemorrhages through cortical vessel rupture.
Why it matters
The review organizes the diverse etiologies and mechanisms of cerebral microangiopathies to guide clinical recognition, differential diagnosis using MRI and genetic tools, and targeted management.
Limits
As a narrative review, it lacks systematic search methods, risk-of-bias evaluation, and meta-analytic synthesis. The abstract provides no specific patient numbers, effect sizes, or quantitative trial outcomes.
