A 65-year-old man with newly diagnosed Alzheimer disease comes to a physician's office with several members of his family. The family is apprehensive about what to expect in the coming months and unsure of whether they can take care of the patient at home. The patient's son says that he has been subscribing to an Internet newsgroup on Alzheimer disease to find out more about his father's illness. He asks the physician what she thinks about receiving advice through online forums.
