Asian Scientist Journal (Jul. 26, 2022)– Older adults with sight impairment are at larger danger of creating dementia, discovered a latest systematic evaluate research. Imaginative and prescient issues are rising in prevalence, with over 2.2 billion folks experiencing some type of imaginative and prescient impairment on the planet. Extra generally recognized in older adults, eyesight issues can hinder one’s day by day life. If left untreated, they will additionally contribute to the cognitive decline and improvement of ailments like dementia in folks.
A multinational staff of researchers from Peking College in China and College of Denver in the US, printed this discovering in Ageing and Psychological Well being, highlighting the significance of early intervention for sight points. This systematic evaluate is among the many first to quantitatively consider the connection between imaginative and prescient issues and dementia by analysing present research.
Dementia is a rising public well being concern and is estimated to have an effect on 78 million folks by 2030.
