Using a smartphone or other personal electronic device (PED) to send text messages produces a “reproducible texting rhythm” that can be detected during video-EEG monitoring, according to Mayo Clinic researchers. In a cohort of 129 patients, this texting rhythm was detected in 27 (20.9%) patients. The rhythm existed in 28% of patients with epilepsy and 16% of those with non-epileptic seizures. The unique pattern was not present in patients when they performed independent tasks or when using a cellphone to make audio calls. The investigators concluded that the reproducible text rhythm “represents a novel technology-specific neurophysiological alteration of brain networks” and proposed that “cortical processing in the contemporary brain is uniquely activated by the use of PEDs.”
