Summary
Periventricular lesions on MRI scans are strongly associated with cerebrovascular risk factors and symptoms in adults over 50. Few individuals without these factors exhibit these brain MRI findings, suggesting a link to vascular health.
Area of Science:
- Neurology
- Radiology
- Vascular Medicine
Background:
- Periventricular high-signal intensity lesions on Magnetic Resonance Imaging (MRI) are frequently observed in older adults.
- The clinical significance and association with cerebrovascular disease are not fully elucidated.
Purpose of the Study:
- To investigate the association between periventricular high-signal intensity patterns on MRI and the presence of cerebrovascular risk factors and symptoms in adults over 50 years of age.
Main Methods:
- Retrospective analysis of 151 adult patients over 50 years old.
- Review of MRI findings for periventricular high-signal intensity patterns.
- Correlation of MRI findings with patient history of cerebrovascular risk factors and reported cerebrovascular symptoms.
Main Results:
- Only 7.8% of patients without identified cerebrovascular risk factors or symptoms showed periventricular lesions.
- A significantly higher prevalence of 78.5% was observed in patients with a history of cerebrovascular risk factors and symptoms.
Conclusions:
- Periventricular high-signal intensity patterns on MRI in adults over 50 are strongly associated with cerebrovascular risk factors and symptoms.
- The absence of these risk factors and symptoms is linked to a low prevalence of these MRI findings.
- These findings highlight the potential role of MRI in assessing cerebrovascular health.
