Singing legend Etta James has been secretly battling Alzheimer's Disease for more than a year. Ms. James had been admitted to Community Hospital in southern California a week ago to treat an infection, but her son has revealed that his mother had been diagnosed with Alzheimer's over a year ago and has battled it in secret ever since. Donto James, who plays in his mother's band, says his mother is suffering from speech difficulties and has contracted the potentially-deadly MRSA virus.
