Eliminates the risk of Alzheimer's risk gene

 

Usually cataract surgery is done so that the eyesight can be normalized. It also happens. After the surgery, there is a significant improvement in the vision of older people. However, there are other benefits of this surgery. Which you may not know about yet.

Relief from forgetfulness

The study, published in the Journal of the American Medical Association (JAMA), claims that cataract surgery reduces the risk of Alzheimer's disease and amnesia. In the decades-long study, the researchers included 3,038 men and women over the age of 65. Of these, 1382 underwent cataract surgery. The rest did not happen. The researchers found that the elderly who underwent surgery had a 29% lower risk of dementia and other forgetful diseases.

The researchers also conducted an analysis based on glaucoma surgery, but it did not show any significant effect on dementia. Factors such as reading, smoking habits, high BP and high BMI were also taken into consideration by the participants. During this time, a great thing that came to light was that those who underwent cataract surgery did not have the APOE-E4 gene, which increases the risk of Alzheimer's.

Dr. Cecelia S. Lee, assistant professor of ophthalmology at the University of Washington, says, "We were surprised to see the results. According to Dr. Lee, people can argue that when they are healthy enough for surgery, it is possible that the risk of a disease like dementia will not be on them in the future. Dr. Lee believes that when we compare it to glaucoma surgery it becomes clear that the disease of catarrect is not just limited to eye surgery, it has other effects as well.

This study also reinforces the results of prior researches that suggest that workouts, social interaction, reading, or intellectual activities can eliminate important risk factors for iq-related decline with vision and hearing loss.

Increase in gray matter in the brain after catarrect surgery

The researchers believe that visual loss can lead to a lack of input in the brain. This can lead to contractions in the brain. This is a major risk factor for dementia. Dr. Lee says that previous research has made it clear that an increase in gray matter was observed in the brain of patients after cataract surgery. That is, there are definitely some benefits of surgery.
