The clinical and electrophysiological features and prognostic factors were evaluated for patients who had follow\u2010up \u22655\u2009years.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We identified 29 patients diagnosed with POLE with a mean age of 20.1\u00a0\u00b1\u20097.6\u2009years. In one\u2010third of the patients, POLE syndrome overlapped with genetic generalized epilepsy (GGE). The overlap group had higher rates of febrile seizure history and self\u2010induction; when compared to pure POLE patients, their EEGs showed more frequent interictal generalized epileptic discharges and posterior multiple spikes during intermittent photic stimulation. During long\u2010term follow\u2010up, the remission rate for POLE was 80%, but EEG photosensitivity persisted in three quarters of patients despite clinical remission, and more than half had relapsed after clinical remission.<\/jats:p><\/jats:sec><jats:sec><jats:title>Significance<\/jats:title><jats:p>This first long\u2010term follow\u2010up study, utilizing newly suggested criteria of the International League Against Epilepsy, showed that POLE syndrome shows a notable overlap with GGE but also has distinctive features. POLE has a good prognosis; however, relapses are common, and photosensitivity persists as an EEG finding in the majority of
