Julianne Moore discusses her father's struggle with Alzheimer's disease, which she witnessed firsthand while filming her role as a professor with early-onset Alzheimer's in the movie "Still Alice." She describes her father's gradual memory loss and increasing inability to care for himself. Moore also highlights the lack of a cure and inadequate federal funding for research, which has shifted its focus to prevention rather than finding a cure. Over 5 million Americans currently suffer from Alzheimer's, and that number is expected to rise dramatically in coming decades without new treatment options.
