New research indicates that neurological conditions, including migraine, stroke, Parkinson’s disease, and dementia, have become the primary cause of global ill-health, resulting in 11.1 million fatalities in 2021.
According to research published in the Lancet, the number of individuals living with or dying from nervous system illnesses has increased drastically over the past three decades, with 3.4 billion people, or 43 percent of the world’s population, impacted in 2021.
According to the data in the Global Burden of Disease, Injuries, and Risk Factors study, from almost 375 million years of healthy life lost in 1990 to 443 million years in 2021, the overall amount of disability, sickness, and early mortality caused by 37 neurological diseases grew by little over 18 percent.
The increase, according to researchers, was caused by variables such as increasing exposure to environmental, metabolic, and lifestyle risk factors like pollution, obesity, and food, as well as the growing global population and longer life expectancy.
The study brought attention to the disparities in health throughout the world, noting that 80 percent of neurological fatalities and illnesses occur in low- and middle-income nations. The mortality rate and years lost to illness, disability, or premature death were five times greater in the most impoverished areas of western and central sub-Saharan Africa than they were worldwide.
The study looked at neurological diseases and neurodevelopmental abnormalities in children for the first time and discovered that they were responsible for 80 million healthy years of life lost globally in 2021, roughly a fifth of the total.
The study highlighted the significance of taking preventative steps to lessen the chance of acquiring certain neurological diseases, chief among them being the reduction of high systolic blood pressure, a measurement of artery pressure during a heartbeat. It was discovered that these actions might avert 84 percent of disease, disability, and early stroke mortality.
