The purpose of this study is to determine the effects of ICA-105665 on the photoparoxysmal electroencephalography (EEG) response in photosensitive epilepsy patients exposed to intermittent photic stimulation.
Subjects with epilepsy with a documented photoparoxysmal response to intermittent photic stimulation will participate. Four subjects will be enrolled at each dose level and will receive a single dose of placebo and a single dose of ICA-105665 during the study, each followed by intermittent photic stimulation. The effects of ICA-105665 on the photoparoxysmal EEG response of each group will be reviewed before the dose is selected for each subsequent group of subjects.
Allocation: Randomized, Control: Placebo Control, Endpoint Classification: Pharmacodynamics Study, Intervention Model: Crossover Assignment, Masking: Single Blind (Subject), Primary Purpose: Treatment

The main study objective is to assess the effect of ACT-709478 in male and female subjects with photosensitive epilepsy following single dose administration
This study will evaluate the efficacy of BGG492 in reducing the sensitivity to flashing lights of patients with photosensitive epilepsy, using EEG as a readout.
The aim of this study is to evaluate the ability of a single oral dose of YKP3089 to abolish or clearly reduce the IPS-induced photo-paroxysmal EEG response in photosensitive epilepsy pati...
PF-06372865 in subjects with photosensitive epilepsy
The purpose of this study is: - To determine the pharmacodynamic (PD) effects of ICA-105665 using the intradermal (ID) capsaicin model in healthy male subjects. - To inv...
The objective of this study was to assess for independent association of anxiety symptoms with epilepsy localization and other epilepsy-related and demographic factors in a large tertiary care adult e...
Epilepsy is a major public health problem worldwide. There are many misconceptions about people's knowledge and attitudes about epilepsy, which influence people's behavior towards patients with epilep...
UV-assisted fabrication of gratings using photosensitive fibers is a well-established technique, based on the UV-induced permanent modification of the refractive index of the fiber material. As a resu...
To characterize epilepsy in an elderly population and describe the prevalence of drug resistant epilepsy (DRE) using recently validated International League Against Epilepsy (ILAE) criteria.
Progressive myoclonic epilepsy (PME) is rare epilepsy syndrome. Although EEG is a useful neurophysiological technique in the evaluation of epilepsy, few EEG abnormalities have been described in PME. S...
An anticonvulsant used for several types of seizures, including myotonic or atonic seizures, photosensitive epilepsy, and absence seizures, although tolerance may develop. It is seldom effective in generalized tonic-clonic or partial seizures. The mechanism of action appears to involve the enhancement of GAMMA-AMINOBUTYRIC ACID receptor responses.
Abnormal responses to sunlight or artificial light due to extreme reactivity of light-absorbing molecules in tissues. It refers almost exclusively to skin photosensitivity, including sunburn, reactions due to repeated prolonged exposure in the absence of photosensitizing factors, and reactions requiring photosensitizing factors such as photosensitizing agents and certain diseases. With restricted reference to skin tissue, it does not include photosensitivity of the eye to light, as in photophobia or photosensitive epilepsy.
A disorder characterized by the onset of myoclonus in adolescence, a marked increase in the incidence of absence seizures (see EPILEPSY, ABSENCE), and generalized major motor seizures (see EPILEPSY, TONIC-CLONIC). The myoclonic episodes tend to occur shortly after awakening. Seizures tend to be aggravated by sleep deprivation and alcohol consumption. Hereditary and sporadic forms have been identified. (From Adams et al., Principles of Neurology, 6th ed, p323)
A disorder characterized by recurrent episodes of paroxysmal brain dysfunction due to a sudden, disorderly, and excessive neuronal discharge. Epilepsy classification systems are generally based upon: (1) clinical features of the seizure episodes (e.g., motor seizure), (2) etiology (e.g., post-traumatic), (3) anatomic site of seizure origin (e.g., frontal lobe seizure), (4) tendency to spread to other structures in the brain, and (5) temporal patterns (e.g., nocturnal epilepsy). (From Adams et al., Principles of Neurology, 6th ed, p313)
An anticonvulsant effective in tonic-clonic epilepsy (EPILEPSY, TONIC-CLONIC). It may cause blood dyscrasias.
Epilepsy is defined as a disorder of brain function characterized by recurrent seizures that have a sudden onset. (Oxford Medical Dictionary). A seizure is caused by a sudden burst of excess electrical activity in the brain, causing a tempora...
