Idiopathic Intracranial Hypertension Mortality in Brazil: An Epidemiological Analysis

Resumo

Introduction: Idiopathic Intracranial Hypertension is an unexplained increase of intracranial pressure, which is defined by the relationship between the cranial components (brain, cerebrospinal fluid, and blood) and its volume, a constant. Objective: To compare, through a prevalence analysis, the mortality of Idiopathic Intracranial Hypertension among the Brazilian regions in the one decade (2011-2020). Methods: Epidemiological, retrospective, descriptive study, carried out with data obtained from the Mortality Information System (SIM/SUS) and data published by the Brazilian Institute of Geography and Statistics (IBGE). From these data, the number of deaths per million people of each Brazilian region per year of the period was calculated. For a more elaborate analysis, the variables age group of patients and gender were considered. Results: In 2011, the national average of deaths per million from Idiopathic Intracranial Hypertension in Brazil was 0,63. The Southern Region featured the lowest mortality rate, with 0,47 deaths per million, and the Northern Region featured the highest rate, with 0,68. Furthermore, males were proven more vulnerable than females, spanning 57% of total deaths that year. Regarding age group, in 2011, deaths were more prevalent in the groups ranging from 20-29 and 50-59 years old, while they were less prevalent in the group ranging from 10-14. In 2020, the national average of deaths per million was 0,40, representing a 37% drop when compared to the beginning, in which the Mid-Western Region had the biggest decrease (71%), and the Northeastern Region had the lowest decrease (17%). In that regard, the region with the biggest mortality rate is the Northeastern, with 0,58, while the lowest rate goes to the Mid-Western Region, with 0,18. In relation to gender, the male population had a reduction of 29% while the female had a reduction of 33%. Moreover, the age group of 20-29 years old had the biggest decrease in that period (76%), and the age group of 50-59 years old, besides having a reduction of 24%, kept the highest average, with 20,6 deaths. Conclusion: This analysis allowed a better understanding about the impact of Idiopathic Intracranial Hypertension in Brazil, since, despite an important decrease in mortality rate during the period of 2011-2020, keeps being a relevant cause of death among the population, mostly affecting the males, the age group between 50-59 years old and the country's Northeastern Region.
