One study showed having either visual or hearing impairment increased the risk of developing dementia by 11% and Alzheimer’s by 10%, and having both visual and hearing impairment raised the risk of developing dementia by 86% and Alzheimer’s by 112%. Another study demonstrated "testing for changes in multisensory function may help identify those at high risk for dementia."
