Magnets in iPad 2 May Alter Settings on Brain Shunt Devices, University of Michigan Study

Researchers at the University of Michigan have found that the Apple iPad 2 can interfere with settings of magnetically programmable shunt devices, which are often used to treat children with hydrocephalus. The iPad 2 contains magnets that can change valve settings in the shunt if the tablet computer is held too close to the valve (within 2 inches). Such a change may result in shunt malfunction until the problem is recognized and the valve adjusted to the proper setting. Patients and their caregivers should monitor use of the tablet computer to ensure that no change is made to the valve settings. The results of this study can be found in the article "Programmable shunt valve affected by exposure to a tablet computer. Laboratory investigation," by Strahle and colleagues, published in the August 2012 issue of the Journal of Neurosurgery: Pediatrics and available online.
