Stroke, Small-Vessel Disease, and Occupation: Systematic Review and Data Analysis

Area of Science:

• Neurology
• Occupational Health
• Epidemiology

Background:

• Novel risk factors for stroke are being explored, including occupational exposures.
• Small-vessel disease (SVD) is a significant factor in stroke development.
• The relationship between specific occupations and SVD risk requires further investigation.

Purpose of the Study:

• To systematically review existing literature on stroke-occupation associations.
• To analyze the relationship between high-risk occupations and SVD indicators in mild ischemic stroke patients.
• To determine if occupational status influences SVD score, white matter hyperintensity volume, or stroke subtype.

Main Methods:

• Conducted a systematic review of 37 papers on occupation and stroke.
• Analyzed data from 414 mild ischemic stroke patients undergoing MRI.
• Assessed associations between high-risk occupations and SVD metrics, adjusting for multiple confounding factors.

Main Results:

• High-risk occupations were significantly associated with higher SVD scores (OR 1.64).
• No significant association was found between high-risk occupations and lacunar stroke subtype (OR 1.03).
• Occupational status did not correlate with white matter hyperintensity volume (β=-0.003).

Conclusions:

• Limited data exists on stroke-occupation associations.
• High-risk occupations are linked to increased SVD scores, suggesting a potential pathway to stroke.
• Further research is needed to clarify the impact of occupation on stroke subtypes.
