It wouldn’t usually be a problem (besides the obligatory joke about a politician and a functioning brain), but Joe Biden actually had brain surgery in 1988 to fix multiple aneurysms. John McCain released updated information from his doctor about his cancer, while Biden doesn’t release scans about his brain?

Newly released medical records from vice presidential candidate Joe Biden do not include the results of any recent brain scans, which some experts consider necessary to assess whether the senator is at risk for a repeat of the brain aneurysms that nearly killed him 20 years ago.

Biden’s most recent physical exam in July showed him to be in good health, according to a letter from Dr. John Eisold that the campaign released Monday. The letter from Eisold, who is the attending physician for Congress, described Biden’s cardiac capacity as excellent.

But the 49 pages of records the campaign released gave no indication that Biden’s doctors sought follow-up tests after the serious aneurysms he suffered in 1988. Medical experts are divided over the need for such precautionary brain scans, but many feel it is the only way to be sure a patient is out of danger.

“If this was my patient, I would re-image every three to five years to make sure no new aneurysm had cropped up,” said Dr. Mark Alberts, a professor of neurology at Northwestern University’s Feinberg School of Medicine.

If John McCain’s full medical records are necessary to assess his capacity to serve (and we’ve be informed that they are), then Biden’s are equally necessary.
