30 Possible Causes for Parietal Sharp-and-Slow-Waves, Paroxysmal Activity - Sharp-Waves Parietal

  • Rolandic Epilepsy

    Abstract The aim of this study was to investigate the frequency of reading, writing, and calculation disabilities in children with typical rolandic epilepsy (RE) and healthy control children. We also aimed to define the possible electroclinical markers of specific cognitive dysfunctions in RE. School abilities were[…][doi.org]

  • Creutzfeldt Jakob Disease

    EEG revealed diffuse and slow activities with periodic sharp-wave complex discharges seen in the right parietal, temporal and occipital lobes.[ncbi.nlm.nih.gov] Single-photon emission CT scan showed markedly decreased cerebral blood flow at the right parietal lobe.[ncbi.nlm.nih.gov]

  • 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]

  • Panayiotopoulos Syndrome

  • Lennox-Gastaut Syndrome

    Interictal There may be focal or multifocal spike-and-wave or sharp-slow waves, with an anterior predominance.[epilepsydiagnosis.org] CAUTION If there is prominent bi-parietal rhythmic theta consider epilepsy with myoclonic-atonic seizures.[epilepsydiagnosis.org] Background The EEG background is abnormal in all cases from onset of seizures, with generalized or focal slowing.[epilepsydiagnosis.org]

  • Angelman Syndrome

    Angelman syndrome is a condition characterized by developmental delay due to abnormalities in the maternally derived chromosome 15q11-q13. Typical features include impaired expressive language, an ataxic gait, and seizures. Hyperactivity may result in accidental bruises and abrasions, raising issues of possible inflicted[…][ncbi.nlm.nih.gov]

  • Early Infantile Epileptic Encephalopathy Type 3

    Epileptic encephalopathy with suppression-burst in electroencephalography (EEG) can evolve into a few types of epileptic syndromes. We present here an unusual case of early myoclonic encephalopathy that evolved into migrating partial seizures in infancy. A female neonate initially had erratic myoclonus movements,[…][ncbi.nlm.nih.gov]
