Introduction: There is scarce information on the demographic profile and diseases affecting neurologic outpatients. Methods: We evaluated 7,519 neurologic outpatients over 20 years at the outpatient clinic of the Department of Neurological Sciences, Hospital-Clínica Kennedy, Guayaquil, Ecuador. Results: Mean age was 48 ± 19.4 years, and 57.8% were women. Common reasons for consultation included headache (33.2%), focal deficits (10.7%), and seizures (9%). The most common categories of neurologic diseases were cerebrovascular (10.6%), degenerative (7.6%), and traumatic (7.1%). Diseases of uncertain/unknown etiology accounted for 50.2% of cases. Young patients were most often evaluated for headache and seizures, while elderly patients usually presented with focal deficits, movement disorders, or cognitive decline. We also found significant variations in the prevalence of neurologic diseases over the study years. While the prevalence of degenerative diseases increased from 5.7% in 1990-1994 to 10.2% in 2005-2009, that of infectious diseases steadily decreased from 3.7 to 2.1% over the study years. Conclusion: There was a dynamic pattern of neurologic diseases over the years. Nowadays, distribution of neurologic symptoms and diseases in our population is more similar to that reported from the developed world than it was 20 years ago.
