    ), status epilepticus or runs of 2–3 s of polyphasic slow/sharp waves (subacute sclerosing panencephalitis).[doi.org] These include periodic lateralising epileptiform discharges in encephalitis, frontal intermittent delta activity in toxic–metabolic or structural abnormalities (if asymmetrical[doi.org]

  • Fragile X Syndrome

    Fragile-X syndrome (FXS) is a frequent genetic form of intellectual disability (ID). The main recurrent mutagenic mechanism causing FXS is the expansion of a CGG repeat sequence in the 5'-UTR of the FMR1 gene, therefore, routinely tested in ID patients. We report here three FMR1 intragenic pathogenic variants not[…][ncbi.nlm.nih.gov]

  • Rolandic Epilepsy

    The interictal EEG in Panayiotopoulos syndrome commonly reveals functional, mainly multifocal, high-amplitude sharp- and slow-wave complexes, with great variability at various[emedicine.com] Generalized spike-and-wave discharges, multiple spike-and-wave discharges, or central temporal or frontal spikes have been reported.[emedicine.com]

  • Vascular Dementia

    Many of the previous studies of vascular dementia using proton magnetic resonance (MR) spectroscopy had been carried out on white matter. However, no proton spectroscopic data of the subcortical gray matter are available in such disease. We report two cases suffering from vascular dementia, with an unilateral[…][ncbi.nlm.nih.gov]

    Ictal EEG may be normal but more commonly shows bifrontal, high-voltage sharp and slow waves or low-ampli tude, fast frontal activity with the clinical seizure.[neupsykey.com] The EEG examination showed diffuse abnormal background activity, with sporadic isolated bilateral sharp waves over the occipital regions (a).[onlinelibrary.wiley.com] The abnormal EEG findings that are most likely to correlate with clinical seizures include spikes or sharp waves, with or without concomitant slow waves, that are generalized[aafp.org]
