Vision impairment may indicate dementia risk. Several systemic conditions are modifiable risk factors for dementia. A new study research revealed that systemic conditions plus vision impairment increases a person’s risk of dementia.
Currently, there is no cure for dementia. Therefore, it is important to identify risk factors to aid in the control and eventual prevention of this pandemic.
The latest study investigates ophthalmic and systemic conditions and their link to dementia.
Various studies have already shown that systemic conditions, such as obesity, depression, hypertension, and diabetes, are leading risk factors for dementia.
The researchers behind the new study analyzed data from the UK Biobank to determine whether ophthalmic conditions indicates a higher incidence of dementia.
For the research, they included 12,364 adults aged 55–73 years between 2005 and 2010 and then followed them up for 11 years until 2021. During this study, they found 2,304 cases of all-cause dementia along with 945 cases of Alzheimer’s disease and 513 cases of vascular dementia.
The researchers found that conditions including stroke only, heart disease only, diabetes only, hypertension only, and depression only in combination age-related macular degeneration was associated with an increased risk of dementia.
“Bottom line for individuals is: If you are experiencing vision loss, it’s important to consult an eye doctor to explore possibilities of sight correction,” Claire Sexton, DPhil, the Alzheimer’s Association’s director of scientific programs and outreach.
