I am interested on occupational/environmental causes of neurodegenerative diseases, with the aim of prevention, treatment and understanding pathogenic mechanisms. My research on occupational manganism documented through clinical, neuroradiological and toxicological assessments its possibility of regression by chelating treatment. This work also allowed to diagnose and treat successfully and definitively a child affected by life-threatening manganese-induced status epilepticus resistant to antiepileptic drugs.
In 1998, upon observing a patient occupationally exposed to herbicides who developed amyotrophic lateral sclerosis, Lou Gehrig's disease became my personal and scientific priority, so, thanks to the collaboration of Prof. Adriano Chiò (Neuroscience, University of Turin), I started a case-control study focused on elucidating occupational and environmental risk factors in amyotrophic lateral sclerosis. The study includes whole-life occupational, clinical and lifestyle history collection for all participants, as well as metal determination (Fe, Mn, Pb, Hg, Al, Cu, Zn, Se, Cd, Cr) on blood/serum by atomic absorption spectrophotometry in a subgroup of patients and matched controls. To date, results indicate a statistically significant excess of ALS incidence among welders.
The role of metals as possible triggers of neurodegeneration in prion diseases and multiple system atrophy are among my most recent research fields, always with the aim of prevention, treatment and understanding.
International collaborations (ITC-ILO Turin, Italy; Rovira I Virgili University, Reus, Spain) give me the opportunity of conducting research and training in occupational health and safety to pursue safe and healthy working conditions in industrialized and developing countries.
Dr. Elena Herrero Hernández graduated in General Medicine and specialized in Occupational Health at the University of Turin, Italy. She was awarded a 4 years grant by Compagnia di San Paolo (Turin, Italy), to support her PhD in Pharmacology and social-environmental Toxicology at the University of Palermo, Italy, and joined CROET in February 2007.
