Loco, because of the difficulty in diagnosis, many

Loco, because of the difficulty in diagnosis, many MD's will opt to begin treatment with available medications to slow the advance of the disease. Any good physician would explain the positives and negatives of a test like Lympro, the same way they do in prescribing a new medication to a patient. Given the devastating affect of AD, many patients, and families will choose to take the test I believe rather than to wait and see. Delay is the problem. Kind of like the good old "PSA" test for prostate cancer. Even though it is quite unreliable, most MD's still choose to use it because there is nothing better available right now, and that delay, if there is cancer can be fatal. Judgment calls are nothing new to the medical community.
