All the drugs that may have helped with Dementia have failed to be effective in halting this disease. Dementia cases are growing, and scientists are looking to other possible causes instead of relying on drugs. They are now focusing on modifiable risks and if behavior may play a part in dementia. A new study was published in JAMA Neurology, in which scientists claim that at least 100,000 cases could have been prevented with healthy vision. 80 to 90% of vision impairment and blindness can be prevented, especially since eye exams, eyeglasses, and eye surgery are relatively inexpensive. Among the modifiable risk factors that were identified besides eyesight were hearing, inactivity and social contact. Our neural system remains healthy through stimulation. This is especially important for eyesight and hearing whose neurons may fade without this stimulation. Both senses are extremely important for older people to stay in touch with the world by making it possible for them to communicate. These modifiable risk factors possibly can lift some of the future burden on our medical system. Not only are they relatively easy to correct but they are drug free.
