What a load of bull!

Researchers announced today that a diagnosis of Alzheimer's can be made with up to 100% accuracy using a cerebrospinal fluid test. That is complete crap because no test in the medical world can ever be 100% accurate. Such a stupid claim is only ever made by a quack who just wants to make money off everyone's suffering. What goes on in this test is that you analyze some of the patient's brain juice for amyloid beta or tau proteins. If you search for those proteins with a spinal tap, then apparently the onset of Alzheimer's can be predicted with a 100% accuracy. A 100% accuracy is impossible because every medical test is bound to give false positives and false negatives (but not both at the same time).
