Learning disability: An abnormal condition affecting children of normal or above-average intelligence, characterized by difficulty in learning fundamentals such as reading (dyslexia), writing (dysgraphia), and math (dyscalculia). [childneurologyfoundation.org]

Photoparoxysmal responses (PPR) were noted in 18 (95%) patients with BAFME but 1 (10%) with EGTCS. CONCLUSION: Faster frequency of GSW, compared with that in EGTCS, accompanied by PPR may be characteristic EEG features of BAFME. [ncbi.nlm.nih.gov]

Response 3 progressive myoclonus epilepsy Spastic Paraplegia with Myoclonic Epilepsy [rgd.mcw.edu]

Generalized paroxysmal abnormalities were found in all cases, whereas a photoparoxysmal response was observed in two. JLA showed a positive–negative spike or a series of wavelets related to myoclonus on the contralateral sensorimotor regions. [onlinelibrary.wiley.com]

Generalized epileptiform discharges were recorded in 25% of cases, and a photoparoxysmal response in 31%. [cris.unibo.it]

Of these nine, seven had multifocal discharges corresponding with contralateral jerky movement and photosensitivity (photoparoxysmal response, photomyoclonic response). SEPs and long latency reflex (C-reflex) were studied in 11 patients (Table 1). [nature.com]

Generalized polyspike wave discharges (in 1 of 36 [3%]) or irregular, generalized, frontally maximal sharp wave discharges (in 1 of 36 [3%]) were seen. [jamanetwork.com]

The EEG shows generalized polyspike and spike-and-wave discharges, frequently precipitated by photic stimulation. [clinicalgate.com]

Bursts of generalized polyspikes and waves (multiple spike-and-slow-wave complexes) may also be seen, [30] especially during sleep and in syndromes with older age of onset. [reference.medscape.com]

Note the generalized polyspikes induced by eye closure. Fig. 12. Landau-Kleffner syndrome (LKS). Four-year-old girl with LKS. Language regression occurred at 3 yr of age. [euroformhealthcare.biz]

[…] and slow-wave complexes at 3 Hz associated with myoclonus.  Interictal EEG is variable and ranges from normal to background slowing and generalized spike and slow-wave activity  Variable course and outcome.  Many resistant to drug therapy  Less favorable [slideshare.net]

Bursts of generalized polyspikes and waves (multiple spike-and-slow-wave complexes) may also be seen, [30] especially during sleep and in syndromes with older age of onset. [reference.medscape.com]

Ten- to 16-Hz rapid spikes with slow waves occur with myoclonic seizures, photosensitivity is common, and abnormalities may occur in sleep. 3.1.7. Epilepsy With GTCS on Awakening GTCS occur exclusively or predominantly shortly after awakening. [euroformhealthcare.biz]

Her EEG showed 3–4 Hz spike and wave discharges. She had a daughter with childhood absence epilepsy, and two sisters and a cousin with seizures (fig 2 , family 1). [jnnp.bmj.com]

The classic interictal EEG finding is the hypsarrhythmia pattern, which consists of a highvoltage, disorganized background with multifocal spike and sharp waves. [euroformhealthcare.biz]

Cortical myoclonus is more commonly encountered in a multifocal form, presenting with multifocal spike discharges. If myoclonus is triggered by stimuli, the term cortical reflex myoclonus is used. [neupsykey.com]
