Dementia cases in the U.S. are expected to double by 2060 when around 1 million Americans are projected to develop the memory-losing condition every year, according to a new study that was published Monday in the medical journal Nature Medicine.
The study found that the risk of developing dementia after turning age 55 is around 42 percent. Dementia is a group condition that includes loss of concentration, judgment and memory.
The collaborative study was funded by the National Institutes of Health to NYU Langone. It relied on the data garnered from the ongoing Atherosclerosis Risk in Communities Neurocognitive Study, which began in 1987 and has tracked the cognitive function and vascular health of participants.
“Our study results forecast a dramatic rise in the burden from dementia in the United States over the coming decades, with one in two Americans expected to experience cognitive difficulties after age 55,” said Josef Coresh, the study’s senior investigator and epidemiologist.
The researchers discovered that a lifetime risk of suffering from dementia for men after turning 55 is 35 percent while it is 48 percent for women. For the most part, the higher risk among women is because of their lower death rates, according to researchers.
The study also found those who had a variant of the APOE4 gene are at a higher risk of developing dementia.
Blood pressure control and preventing diabetes are one of the ways to slow down cognitive decline and prevent dementia, according to researchers.
“The pending population boom in dementia cases poses significant challenges for health policymakers in particular, who must refocus their efforts on strategies to minimize the severity of dementia cases, as well as plans to provide more healthcare services for those with dementia,” Coresh said.
A study from September last year found nearly one in five dementia cases are linked to vision impairment, suggesting that diagnosis rates could drop with more sufficient eye health.
