Single hair strand could provide biomarker for amyotrophic lateral sclerosis

Researchers at the Icahn School of Medicine at Mount Sinai have shown for the first time that a single strand of hair can reveal unique elemental patterns that distinguish people with amyotrophic lateral sclerosis (ALS) from healthy individuals. The findings, published in eBioMedicine, suggest that a simple, noninvasive hair-based test could one day speed up ALS diagnosis and improve patient care.
