Increased deaths from neurological diseases but still below the state average


The Spanish Society of Neurology (SEN) presented the report "Impact of neurological diseases on Spanish mortality". Prepared with the latest data published by the National Institute of Statistics (INE), the report aims to determine the burden of neurological diseases in Spanish mortality and in the different autonomous communities, as well as the evolution of neurological diseases. with the highest mortality rate in the last decade.

According to the data available, more than 78,000 Spaniards died last year due to neurological diseases, which means that they are the cause of 19% of deaths occurring every year in Spain. In Castile and Leon, 4,900 people died because of this cause, accounting for 17.3% of all annual deaths.

Figures that are not equally distributed by sex. While in Spain they accounted for 14.6% of male deaths, the number rises to 23.6% in the case of women (13.5% and 21.2%, respectively, in Castilla y León).

"But in addition, these numbers could be even higher, because by cataloging the International Classification of Diseases, we can not count deaths from traumatic brain injury." According to our estimates, there are approximately 20,000 severe head injuries each year, 40% of those who suffer unfortunately end up dying, "he says. Juan Carlos Portilla, cocal of the Spanish Society of Neurology.

Cantabria (24.1%), Basque Country (22.6%) and Navarre (22%) are Autonomous Communities where there is a higher percentage of mortality due to neurological diseases in relation to the total number of deaths, and are also regions where more women die from this cause (30.6%, 27.8% and 27.6%, respectively). In the case of men's mortality due to neurological diseases, La Rioja (19.4%) is in first place, followed by Cantabria (17.8%) and the Basque Country (17.7%).

On the other hand, the Canary Islands (14.5%), the Community of Madrid (16.35%) and Extremadura (16.8%) are regions where there is a lower percentage of deaths due to neurological diseases – in addition to cities . Autonomous regions of Ceuta (14.7%) and Melilla (15.8%) – and also present the lowest mortality rates due to neurological diseases in men and women.

Another of the report's findings is that although mortality in Spain has increased over the past 10 years, the number of deaths from neurological diseases has not increased by the same proportion. While Spanish mortality increased 10.5% in this period, when we speak only of the mortality of neurological diseases, it reaches 18.5% (16.5% in men and 19.8% in women, compared with 7.6% and 13 , 7%, which increased the Spanish mortality, respectively, in these 10 years). In Castile and Leon, mortality increased by 9.7% in the last 10 years, while mortality from neurological diseases increased by 13.15%.

If we take into account mortality by specific entities, cerebrovascular diseases are the leading cause of mortality in women, among all possible causes and not only neurological causes, and the second cause in the entire Spanish population. Currently, cerebrovascular diseases in Spain produce more than 27,000 deaths per year (11,500 in men and 15,500 in women). On the other hand, Alzheimer's disease is the second most neurological disease with the highest mortality, with about 14,800 deaths per year (4,300 in men and 10,500 in women).

However, in the last 10 years, mortality due to cerebrovascular disease is decreasing – although its incidence continues to increase – thanks to improved treatments. Ten years ago, there were 32,900 deaths in Spain due to cerebrovascular diseases, which means that this period reduced mortality by 17.6%. In the last 10 years, mortality from cerebrovascular diseases decreased by 11.3% in Castile and Leon.

On the contrary, in the last 10 years Alzheimer's disease mortality has increased in Spain by more than 61% (63.7% in women and 55.8% in men). Over the past 10 years, Alzheimer's disease mortality has increased by more than 42.9% (54.4% in women and 20.2% in men) in Castile and León.

And is that, beyond age, there are other series of risk factors, such as high blood pressure, cholesterol or diabetes, which greatly increase the likelihood of suffering any of these diseases. The Spanish Society of Neurology believes that the prevention of these risk factors could at least delay the onset of neurological diseases with a higher mortality rate for several years and theoretically reduce the likelihood of suffering from these diseases by up to 50%.
