A novel disease-specific biomarker for diagnosis and monitoring of semantic variant primary progressive aphasia

Takeaway

  • The semantic variant primary progressive aphasia-related pattern may represent an objective diagnostic tool.

Why this matters

    Diagnosing and monitoring semantic variant primary progressive aphasia remains clinically problematic. This novel study established a semantic variant primary progressive aphasia-related pattern using principal component analysis. The findings suggest that this semi-quantitative method could be used as an objective tool to diagnose and monitor semantic variant primary progressive aphasia.
