Richard Lipton is an investor in a new gadget that sends magnetic pulses through the brain. A medical researcher, Lipton published results of a study that claims to prevent migraine headaches. ABC's Sharyn Alfonsi and CBS' Jon LaPook both offered free publicity to his TransCranial Magnetic Stimulator. Lipton claims that if the TCMS is applied when a migraine patient experiences an "aura," which is the warning symptom of an attack, 40% of them can be averted. Alfonsi cautioned that the contraption has not been approved by the Food & Drug Administration while LaPook cautioned that the magnet is no miracle cure. LaPook explained that the aura--"visual changes like flashing lights, zigzagging patterns, blind spots"--is a warning sign for only 25% of all migraines. Do the math and that means Lipton's contraption prevents just 8% of cases, of which half can be prevented by a placebo, according to Lipton.
