Photoparoxysmal responses.

چکیده
Sixty-five outpatients with photoparoxysmal response (PPR) during routine EEG were studied. The PPR showed prevalence in women (75.4%). Seizures were found in 66.1% of cases. The rest recordings were abnormal in 41.8% with prevalence of generalized paroxysm. Eight patterns of PPR were observed, being polyspike mixed to slow wave the most frequent (53%). The epileptic group showed a bimodal distribution in the several bands of photic stimulation, near 8 and 20-24 Hz. A sustained paroxysmal abnormality persisting after the photic stimulation was present in 6 epileptic patients.

No effects of the gonadal hormones on photoparoxysmal EEG responses in idiopathic generalised epilepsy
PURPOSE It is accepted that the estradiol hormone is proconvulsant and progesterone is anti-convulsant. In this study the effects of gonadal hormones on photoparoxysmal responses on EEG in idiopathic generalised epilepsy were researched. METHOD Twenty-two women with photosensitive idiopathic generalised epilepsy having regular menstrual cycles were recruited into the study. Patients presentin...
متن کاملSubdural electrode recording of generalized photoepileptic responses
We evaluated the spatiotemporal distribution of photic driving (PDR), photoparoxysmal (PPR), and photoconvulsive (PCR) responses recorded by intracranial electrodes (ic-EEG) in a patient with generalized photosensitivity and right frontal lobe cortical dysplasia. Intermittent light stimulation (ILS) was performed thirteen times in nine days. Cortical responses to ILS recorded by ic-EEG were rev...
متن کاملThe relationship between photosensitive temporal lobe epilepsy and eye closure activity
We describe a 16-year-old female patient affected by photo-induced temporal lobe epilepsy. During intermittent photic stimulation she showed a photoparoxysmal response in the EEG. This case was diagnosed from clinical symptoms, single photon emission computer tomography, and EEG data. The clinical symptoms were relieved by the administration of carbamazepine. As these photoparoxysmal responses ...
متن کاملSeasonal variations in the incidence of photoparoxysmal response to stimulation among photosensitive epileptic patients: evidence from repeated EEG recordings.
EEG records of photosensitive epileptic patients with repeated EEG recordings at different seasons of the year, were examined for the occurrence of photoparoxysmal response to photic stimulation (photoparoxysmal discharges (PPD]. Recordings in summer showed a lower incidence of PPD compared with recordings in other seasons. Recordings in winter showed a higher incidence of PPD compared with rec...
متن کاملCharacteristics of an adult photosensitive cohort.
Intermittent Photic Stimulation (IPS) is a well recognized provocation maneuver during EEG recording which helps in identifying underlying photosensitivity. The frequency and characteristics of various responses to photosensitivity among our adult patients was determine. EEGs of subjects > or =15 years from 2003-2006, were reviewed. Two main photosensitive responses were observed: Photoparoxysm...
