Here's more evidence for the charge that the health-care industry overscreens, overdiagnoses, overtreats and often overcharges.

A recent study by the University of Michigan published in the Archives of Internal Medicine found that expensive tests like MRIs are used more often than more effective screenings that cost less.

The study concerned peripheral neuropathy, a disorder in which the nerves relaying information to and from the brain don’t work properly. Symptoms include tingling, burning and numbness in the arms and/or legs. Diabetes is the most common cause of peripheral neuropathy.
