After completing her neurology training at Hospital Ramon y Cajal in Madrid, Dr Delia Chaverri entered as staff Neurologist at the Hospital Carlos III. There she combined her duty as general neurologist with a special involvement with ALS patients. With Dr J. Mora, she established the first ALS Unit in Spain. Devoted mainly to patient care, she has participated in a large number of ALS international clinical trials. In 2014, the Hospital Carlos III merged with Hospital La Paz, forming a single institution where she has been coordinating the ALS unit since 2016. More than 300 patients are treated regularly at the unit by a high level multidisciplinary team.
