Terry Heiman-Patterson, MD, Professor of Neurology at the Lewis Katz School of Medicine at Temple University, offered insight to Reuters Health about a study published in Nature Medicine that increases in brain perivascular fibroblasts and their protein SPP1 may better predict life expectancy in patients with sporadic amyotrophic lateral sclerosis, or ALS. Dr. Heiman-Patterson was not involved in the study. MD Alert picked up the Reuters Health article.
