Can magnetic fields cure genetic defects? FUCK NO, but that's what proponents of neurofeedback would bullshit you into believing. Plan to pay hundreds of dollars per session. Unsurprisingly many many sessions will be required. Similarly unsurprising: insurance companies do not cover fraudulent-science so you will be wasting only your own money.
If you could instantly think your way out of disease or will changes to your DNA medicine would be obsolescent quickly. OBVIOUSLY neurofeedback is fraud. Any doctor offering it under his shingle risks losing his license, the privilege of practicing medicine, or stiff fines. REPORT these tricky motherfuckers to their state medical board
