DR. OZ's mom has Alzheimer's, and it's a particularly hard pill for him to swallow.He says, quote, "I'm feeling guilty because I completely missed the signs until fairly late in the process." Oz says that he and his sisters noticed little things, like the way she would struggle to find certain words, or dress oddly.But they never connected the dots. He says, quote, "Alzheimer's is like a snake in the grass.You don't see it.You only see the effects of it suddenly.And if there's a wind blowing the grass, you don't even notice the grass moving strangely.It sneaks up on you."
