Key result
Left MCA stroke presents with atypical contralateral SREDA mimicking focal seizures on EEG.
Why the study?
The occurrence of atypical unilateral SREDA in patients with contralateral structural cerebral abnormalities such as stroke is rare and not previously described.
Case Report (n=1)
This case report describes a rare instance of atypical SREDA associated with a contralateral structural cerebral abnormality, providing potential insight into its underlying mechanisms.
May warrant EEG caution to avoid misdiagnosing seizures in stroke; leaves open the spectrum of SREDA variants in cerebrovascular disease.
Subclinical rhythmic electrographic discharges in adults (SREDA) is a well-known benign EEG phenomenon. However, the occurrence of SREDA is rare, and atypical forms are even more elusive, with only few cases reported in the literature. Herein, we describe a case of a 77-year-old woman with a left middle cerebral artery stroke and paroxysms of rhythmic, sharply contoured activity over the right central head region, mimicking focal seizures on EEG, that were determined to represent atypical SREDA. To our knowledge, no case of SREDA with a contralateral structural cerebral abnormality has been described, and its occurrence offers some limited insight as to the mechanisms underlying this mysterious entity.

Campbell et al. (2016) conducted a case report in Stroke and atypical SREDA (n=1). Left middle cerebral artery stroke was evaluated. A 77-year-old woman with a left middle cerebral artery stroke exhibited atypical unilateral SREDA over the contralateral right central head region, mimicking focal seizures on EEG.
