Is Alzheimer's diagnosed with a blood test?
I'm a man in late middle age, and I'm worrying that I'm beginning to see symptoms of Alzheimer's in myself. Is there a blood test I can take to determine whether or not I have this? Honestly, I'm afraid of getting the scans, because I'm claustrophobic and terrified of getting brain cancer from the radiation.
