The author's grandfather, a grandfather who taught his son, Alzheimer's disease, was the kindest man I've ever known and taught me not to speak ill of others. He also had a tenderness with livestock and sheep, taught me how to plant vegetables and play piano and the Irish flute. However, the diagnosis of Alzheimer's came to light ten years ago, with the official cause of his death being a heart attack and a broken heart. The author reflects on the complexity of the disease's story, with new treatments showing modest results but not enough to halt its decline. The current scientific approach to tackling Alzheimer's is now focusing on attacking the metabolic, metabolic, and genetic predispospospositions, not the symptom, but the aging system. Over 7 million Americans currently live with Alzheimer's.
