Touch-screen automatisms in the digital age.

ABSTRACT

OBJECTIVE: To describe a novel set of gestural automatisms related to the use of digital screens on smartphones and tablets in patients with epilepsy. METHODS: Representative patients were selected from among those admitted to the Epilepsy Monitoring Unit at the Toronto Western Hospital between April 2016 and January 2020, and included if they exhibited automatisms clearly related to or mimicking digital device use. RESULTS: In total 5 patients were included, 4 female. All had temporal lobe epilepsy 2 had left mesial temporal sclerosis and 3 had normal imaging. Nearly equal numbers of seizures began with right (5/9) and left (4/9) temporal onsets, with most automatisms occurring after seizure propagation to bilateral temporal involvement (6/9). Left-handed automatisms were most common (8/9). The majority of the automatisms (7/9) were perseverative on device usage prior to the seizure. CONCLUSION: Gestural automatisms appear related to the contemporary lived experience, culture, and habitual behaviour of patients with epilepsy. In the modern era, the use of smartphones and tablets are both common and habitual for many, and this case series shows that touch-screen automatisms may be added to the semiological panoply of temporal lobe seizures.
