Grey's Anatomy-Fact or Fiction?

So, I was eating dinner at the Corner Bakery the other night and couldn't help but over hear a conversation across the way. Two women were sitting and discussing what sounded like the health condition of one of their mothers. Apparently, she had just been diagnosed with Alzheimer's. They continued on in discussing what the doctor had told her to expect in the coming weeks, months, years. As their conversation continued, one of the women asked her dinner mate if she ever watched Grey's Anatomy? When I heard this, I immediately thought, what does this have to do with your mother? Well, it didn't take long to find out. She conveyed, in a very matter-of-fact manner, that Meredith's mother had Alzheimer's as well, but she came out of it at one point and remembered her daughter, but came back thinking it was year's earlier than it actually was. Now, I'm not going to lie, but this disturbed me for a number of reasons. First, Meredith's mother suffered from Dementia. Wrong illness. Second, Grey's Anatomy is a show, produced for entertainment, acted out by actors, and should not in any way be used as a reference for medical diagnoses. Third, I wondered if at some point in my life I will be that lady--comparing my life to that of the latest soap opera and identifying my situation with the lead character. If I ever do get to that point, someone, please, slap me and tell me to snap out of it. And if I don't, I give you permission to take away my driver's license. Institutionalize me. Drug me. Because, I apparently should not be a part of society any more...is this a little dramatic? I don't know. But, I'm pretty sure I won't be old and talking to my cat (I dislike cat's), so that's probably the only other alternative. However, I like to think that if I've lost it, that at least I'll be spunky enough to raise a little hell in the rest home instead of moping around complaining about my latest hip replacement.
