Expanding the spectrum of the “texting rhythm” in <scp>EEG</scp>

A 49-year-old male was evaluated with video-electroencephalography for possible epilepsy due to recurrent anxiety with confusion. EEG showed 5–6 Hertz monomorphic, generalized, frontocentral activity during tasks like reading, texting, computer work, and LEGO play (Figure 1). This ceased when relaxed or asleep (Figure 2). Two non-epileptic events were captured, and MRI was normal. Frontal-midline theta rhythms relate to tasks requiring cognitive control.1, 2 Texting rhythm (TR) is a novel pattern defined as reproducible, stimulus-evoked, generalized frontocentral monomorphic 5–6 Hertz activity.3-6 EEG/MEG studies suggest frontal-midline theta originates in the dorsal anterior cingulate and medial prefrontal cortex.1, 2 TR may involve broader networks, including brainstem–thalamic, occipital–parietal, and prefrontal neocortical networks.3, 7 TR-like patterns, seen in knitting, may arise from the same regions and the supplementary motor cortex for motor planning and visuospatial processing,5 possibly also explaining LEGO-related rhythms. TR, a normal finding seen in 24% of adults, should not be misinterpreted as pathologic.3 The authors report no disclosures relevant to the manuscript.
