The previously unidentified “texting rhythm” (TR) is a new and specific waveform linked to using new technology associated with text messaging, according to a study presented at ACNS, held in February in Houston. It likely reflects a visual-cognitive network activation unique to cellphone use. 
Benedetto S. DiCiaccio, MD, and colleagues at the Mayo Clinic Jacksonville in Jacksonville, Florida, evaluated 66 patients (51 female, mean age 34.74) with paroxysmal events (38 with epileptic [ES] and 23 with non-epileptic seizures [NES]) who were admitted for video-EEG monitoring. According to the study authors, the TR is a generalized burst of 5-6 Hz theta maximal in the fronto-central head regions during active texting. Other methods of activation included finger tapping/swiping, mathematic computation, scanning eye movements, speech/ cognitive testing, and audio telephone conversations. The presence of a TR was compared between patients with ES and NES and between methods of activation. 
Following data analysis, the TR was found to be highly specific to texting without the appearance of a similar waveform during mental activation or audio cellphone use (P <0.0001) . A TR was present in 44.0% of patients lasting from two seconds to continuous runs during the activity. Further, it was present in 57.9% of patients with ES but only 17.4% of patients with NES (P=0.0019). Additionally, the average age for those with a TR was 30.45, while those without a TR was 38.11 (P=0.0117).
