Sleep\u2010related rhythmical movement disorder (SRRMD) is a benign condition typically seen in early childhood, characterised by stereotyped, rhythmical repetitive movements involving large muscle groups, predominantly during Stage II of non\u2010REM sleep. These movements can closely mimic features of sleep parasomnias, hypermotor seizures or psychogenic non\u2010epileptic seizures (PNES), complicating the diagnostic approach. We present a case of an adolescent female with comorbid SRRMD and PNES and a clinical approach to distinguish between them.<\/jats:p>","DOI":"10.1111\/jsr.70302","type":"journal-article","created":{"date-parts":[[2026,2,9]],"date-time":"2026-02-09T23:19:18Z","timestamp":1770679158000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Is It Psychogenic Non\u2010Epileptic Event, Sleep Related Rhythmical Movement Disorder or Hypermotor Seizure?"],"prefix":"10.1111","volume":"35","author":[{"given":"Akshaya Rathin","family":"Sivaji","sequence":"first","affiliation":[{"name":"Epilepsy Center, Neurological Institute University Hospitals Cleveland Medical Center  Cleveland Ohio USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sanah Virdah","family":"Parvez","sequence":"additional","affiliation":[{"name":"Epilepsy Center, Neurological Institute University Hospitals Cleveland Medical Center  Cleveland Ohio USA"},{"name":"Case Western Reserve University School of Medicine  Cleveland Ohio USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jennifer","family":"Waldron","sequence":"additional","affiliation":[{"name":"Epilepsy Center, Neurological Institute University Hospitals Cleveland Medical Center  Cleveland Ohio USA"},{"name":"Case Western Reserve University School of Medicine  Cleveland Ohio USA"},{"name":"Division of Epilepsy UH Rainbow Babies &amp;
