Epilepsy with photosensitivity (PSE) is one of the reflex epilepsy types with pathophysiology still unexplained. In our study we aimed to evaluate the clinical, electroencephalogram (EEG) and prognosis of patients with PSE diagnosis.
A total of 44 patients with PSE diagnosis according to international classification were included in this retrospective and cross-sectional study. The age, gender, syndrome, clinical and EEG characteristics of patients, and treatment response were investigated.
The mean age was 22.09±6.49 years for 28 females and 16 males included in the study. Of patients, 17 had idiopathic photosensitive occipital lobe epilepsy (IPOLE), 11 had juvenile myoclonic epilepsy (JME), 11 had other PSE and 5 had juvenile absence epilepsy (JAE), with the most common visual trigger factors television and sunlight. In terms of seizure type, the most common was generalized tonic clonic seizure (GTCS), with myoclonus, absence and other seizure types observed. There was family history present in 17 patients and valproic acid was most commonly used for treatment.
As noted in the literature, our data show that PSE has defined age group and clinical presentation, good prognosis but requires correct choice of medication for treatment. It is thought that good description of these epilepsy types will reduce misdiagnosis and mistreatment rates.
