“…The proprioceptive input serves as an important afferent to the postcentral area in PLE, triggering the spread of seizures. 8 However, one important challenge of proprioceptvie-induced seizures is the differential from paroxysmal movement disorders. The proprioceptive triggers in epileptic patients can be described as passive or active movement of the extremities, 8,9 misleading clinicians to other diagnosis such as paroxysmal kinesigneic dyskinesia (PKD).…”

Parietal lobe epilepsy (PLE) is characterized by frequent auras and diverse semiologies, largely due to the elaborate connections of the parietal lobe to other regions. c Proprioceptive-induced seizures are a rare but unique expression of PLE. They are characterized by motor seizure attacks precipitated by proprioceptive stimuli of the extremities.cFocal cortical dysplasia (FCD) is a common etiology of drug-refractory PLE. Bottom-ofsulcus dysplasia (BOSD) represents a distinctive subtype notable for its highly localized and subtle lesions, as well as an excellent surgical outcome. Oy-sters cPLE should be part of the differential in patients with paroxysmal movement disorders. Thorough history taking, especially of the triggers and motor attacks, is essential for a correct diagnosis. cThe presence of localized rhythmic epileptic discharges (REDs) on electroencephalography serves as an important indicator of the easily misdiagnosed FCD. A thorough history taking, careful review of MRI, and application of multimodal imaging postprocessing further facilitate subtle lesion detection. cA transient response to antiseizure medications is common in FCD-associated epilepsy. However, early referral to surgery evaluation should be considered because drug refractoriness is likely to develop with time.

“…Epileptic nature of the attacks is shown by the ictal EEG recordings. 75 The maximum EEG electronegativity is seen at the central vertex electrode in the seizures induced by walking. 76 Most of patients respond properly to insulin therapy in non-ketotic hyperglycemia and only a few of them need AEDs where carbamazepine and clobazam can be used in the patients requiring treatment.…”

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-sensitive or photosensitive epilepsies constitute a large proportion of the RE and are mainly related to genetic causes. Reflex epilepsies may present with focal or generalized seizures due to specific triggers, and sometimes seizures may occur spontaneously. The stimuli can be external (light flashes, hot water), internal (emotion, thinking), or both and should be distinguished from triggering precipitants, which most epileptic patients could report such as emotional stress, sleep deprivation, alcohol, and menstrual cycle. Different genetic and acquired factors may play a role in etiology of RE. This review will provide a current overview of the triggering factors and management of reflex seizures.

“…The effects of sensory stimuli, mental activity and emotional state have been studied on generalized discharges (Symonds 1959;Jung 1962;Paulson 1963;Arseni et al 1967) and on petit ma1 absence (Jung 1962; Ounsted and Hutt 1964;Vidart and Geier 1967;Guey et al 1969). There are few studies of interictal focal activity.…”

SUMMARY The number of focal spikes or sharp waves was studied in 5 epileptic children during movement of the limbs and during psychological tests. Another patient studied had frequent petit mal absences. All the patients showed a clear diminution in paroxysmal activity during simple arithmetical calculations, and rebound, i.e. increase in the number of discharges, after the tests. In the 5 children with focal spikes and sharp waves, both mental tests and passive and active movements of the limbs caused the abnormalities to diminish or disappear independent of the site of the EEG focus. The effect was more marked when the limbs were moved contralateral to the affected hemisphere. There was rebound with increase in the number of spikes and sharp waves after the movements as well as after the tests. In the patient with petit mal attacks the number of cortical discharges diminished during mental tests but was not modified during movements of the limbs. Also in this patient there was rebound with an increase in spike‐and‐wave discharges after the test. RÉSUMÉ On a étudié le nombre des pointes ou des pointes lentes focales chez 5 enfants épileptiques au cours de mouvements des membres et pendant des tests psychologiques. Un autre sujet étudié présentait de nombreuses absences petit mal. Chez tous les patients, il y avait une nette diminution de l'activité paroxystique pendant des calculs arithmétiques simples et un “rebond” c'est à dire une augmentation des décharges après les tests. Chez les 5 enfants présentant des décharges de pointes et pointes lentes focales, les tests mentaux et les mouvements passifs ou actifs diminuaient ou faisaient disparaître les décharges, indépendamment de la topographie du foyer EEG. La diminution des décharges focales sur l'hémisphère était plus marquée lors des mouvements des membres controlatéraux. Il y avait un “rebond” après la fin des mouvements et des tests. Chez le sujet avec absences typiques, le nombre des décharges diminuait pendant les tests mentaux, mais n‘était pas modifié par les mouvements. Chez ce dernier également, il y avait un “rebond” avec augmentation des décharges de pointe‐ondes après les tests.
