Dementia is a disease in which a person's cognitive abilities are impaired. Dementia causes gradual deterioration of mental abilities, memory, ability to navigate in time and space, recognize people and objects.
According to the data, people with age-related macular degeneration, cataracts and eye disease that is related to diabetes may have a higher risk of developing dementia.
Researchers collected health information on approximately 12 people aged 55 to 73, and then followed them for 15 years, noting who was diagnosed with dementia and age-related eye diseases. It found that the risk of dementia was 26% higher among people with age-related macular degeneration, 11% higher among people with cataracts, and 61% higher among people with eye disease caused by diabetes. However, glaucoma was associated with an increased risk of developing dementia.
Numerous eye diseases also increased the risk to humans. Those who had two eye diseases were at higher risk of dementia than those who had only one disease. In addition, people who had at least two eye diseases and other health problems such as diabetes, heart disease, stroke or depression were almost three times more likely to develop dementia.
