According to a recent study, the risk of dementia in older adults can be increased by problems with eyesight. According to a recent systematic review and meta-analysis of 16 studies comprising 76,373 individuals, older adults who suffer from untreated eye problems could be at higher risk for developing dementia. The results of the study, reported in the peer-reviewed journal Aging and Mental Health, suggest a need for further studies examining how treating older people’s eyesight problems, such as through eyeglasses or cataract surgery, might prevent cognitive issues and dementia.
People’s lives are greatly affected by this condition. As the disease progresses, individuals experience more significant memory loss and changes in personality and behaviour. As a result, they will ultimately become entirely dependent on others to take care of them.
The researchers included 16 studies involving 76,373 participants, five cross-sectional studies and 11 longitudinal studies published through April 2020. From these studies, the authors examined the association of visual impairment with cognitive outcomes in older adults.
