Juan Toledo Atucha

Dr. Toledo’s focus of interest is the study of neurodegenerative diseases, mainly Alzheimer’s disease and Lewy body disease, encompassing Parkinson’s disease -with and without dementia- and dementia with Lewy bodies, and the overlap of different neurodegenerative and non-neurodegenerative diseases in subjects with dementia. In his studies he combines cerebrospinal fluid, neuroimaging, neuropathological and clinical measures to model disease progression and biomarker changes and predict clinical outcomes. His main focus of interest is the characterization of Alzheimer’s disease biomarkers, the study of preclinical Alzheimer’s disease stages and the characterization of prevalence and biomarker correlates of coincident diseases in demented patients. Dr. Toledo graduated from University of Navarra medical school in 2004 and completed his residency with Clinica Universidad de Navarra in 2009. He then moved to the USA, where he worked as a researcher in the University of Pennsylvania. Dr. Toledo then completed his neurology residency at Houston Methodist Hospital, followed by a movement disorders fellowship at the University of Florida. He is currently an Assistant Professor of Neurology at Houston Methodist Hospital.
