My grandmother was just recently diagnosed with acute dementia. (There is a family history of alzheimers and dementia.) She has had numerous test to figure out what is the cause. It seemed to be prolonged high blood pressure and vitamin deficiencies due to her not eating or taking her medication. We need to know what is the best doctors and hospitals for this condition in the Chicagoland area. We are open to information from any research groups on this topic. We are also open to travel to see an expert on the topic.
