Global Increase of , Neurological Disorders , 'Very Concerning,' Researchers Say.br 'Newsweek' reports that a new study br warns that neurological disorders have br become more common worldwide.br According to a team of international researchers, br the number of people with such conditions has br risen "substantially" over the past thirty years.br These conditions include Alzheimer's disease, br as well as other forms of dementia, br meningitis and stroke. .br In 2021, the team found that 3.4 billion people had br one of these neurological conditions, accounting for br approximately 43 of the world's total population.br Researchers attribute the alarming br statistic to a rapidly aging population and br increases in lifestyle risk factors.br Researchers attribute the alarming br statistic to a rapidly aging population and br increases in lifestyle risk factors.br Over a 31-year period, researchers found br an 18 increase in disability, illness and br premature death related to these conditions.br 'Newsweek' reports that the team's findings highlight the br need for more research into these neurological conditions, br which have proven to be extremely difficult to treat.br 'Newsweek' reports that the team's findings highlight the br need for more research into these neurological conditions, br which have proven to be extremely difficult to treat.br Because many neurological conditions br lack cures, and access to medical care br is often limited, understanding br modifiable risk factors and the br potentially avoidable neurological br condition burden is essential to br help curb this global health crisis, Katrin Seeher, study co-lead author and mental health br specialist at WHO's Brain Health Unit, via 'Newsweek'.br Because many neurological conditions br lack cures, and access to medical care br is often limited, understanding br modifiable risk factors and the br potentially avoidable neurological br condition burden is essential to br help curb this global health crisis, Katrin Seeher, study co-lead author and mental health br specialist at WHO's Brain Health Unit, via 'Newsweek'.br The team's findings were detailed in a studybr published in the journal 'The Lancet Neurology.'.br Neuroscience research is now br progressing rapidly offering br hope through new treatments br for diseases like dementias and br through better understanding br of lifestyle modifications br to best care for our brains, Tara Spires-Jones, president of the British Neuroscience br Association and group leader in the U.K.
