Dr. Alois Alzheimer, a German psychiatrist, discovered Alzheimer's disease in 1907. He noticed that a female patient slowly lost her memory and ability to think and talk and that she developed judgment problems. After her death, he viewed her brain through a microscope and noticed abnormal growths, which he called plaques and tangles, in parts of her brain. These changes occur in the brain of everyone with Alzheimer's disease.
