Investigators from multinational institutions hypothesized that disruption of CHD2, which encodes chromodomain helicase DNA-binding protein 2, would be associated with common forms of photosensitive epilepsy or photosensitivity manifesting as a photoparoxysmal response alone.
Sternutatio (sneeze) is a poorly understood polysynaptic physiologic reflex phenomenon; even less are some variations of the such as photic sneeze (photo-sternutatory reflex), sneezing induced by bright light, overeating, plucking eyebrows (palpebro-sternutatory reflex) and paroxysmal sneezing, episodes intractable sneezing. The present contribution reviews various aspects patho-physiology its ...
Reflex epilepsies (REs) are identified as epileptic seizures that are consistently induced by identifiable and objective-specific triggers, which may be an afferent stimulus or by the patient's own activity. RE may have different subtypes depending on the stimulus characteristic. There are significant clinical and electrophysiologic differences between different RE types. Visual stimuli-sensiti...
Activation of specific cortical territories by sensory stimuli or of less restricted areas of the brain by cognitive stimuli is known to induce apparently generalized seizures in predisposed patients; this is clinically and electroencephalographically distinct from reflex triggering of partial seizures. Photosensitive patients may have seizures when exposed to environmental stimuli producing ap...
In this interesting paper, the authors have successfully quantified the predictive capabilities of the single-blind, Phase IIa photosensitivity model. Most importantly, their conclusion stresses that potential AEDs showing suppression of the pathological generalized epileptogenic reaction to Intermittent Photic Stimulation (IPS) also show efficacy in phase III double-blind placebo-controlled AE...
Marshall Hall (1790-1857), who graduated from the University of Edinburgh's Medical School in 1812, was considered one of the greatest physiologists of his day. He advanced knowledge in various areas of medicine, in particular elucidating the mechanism of reflex activity in 1833. Hall suggested that convulsive epileptic seizures arose from heightened activity in the afferent limb or the central...
In discussing the significance of reflex epilepsy Critchley (1933) stated that an incoming stimulus would hardly provoke convulsive phenomena unless there was a state of supercharge in the central nervous system. Holmes (1927) described cases in which a cortical lesion apparently caused the disturbed peripheral response to a specific stimulus, and he considered that the appropriate external sti...
