80 Possible Causes for Occipital Sharp-and-Slow-Waves, Onset between 6 and 14 Years

  • Panayiotopoulos Syndrome

    EEG showed right occipital high-amplitude sharp and slow-wave complexes followed by brief generalized discharges of slow waves.[ncbi.nlm.nih.gov] Clinical context Panayiotopoulos syndrome is characterized by onset of seizures between 1 and 14 years of age (majority between 3 and 6 years).[epilepsydiagnosis.org] The electroencephalogram manifestations are severe with long runs of high amplitude occipital sharp and slow waves.[adc.bmj.com]

  • Epilepsy

    Contemporary drug therapy fails to control epileptic seizures in some 30% of patients, resulting in the need to employ other measures when they appear practicable. A good deal of potentially relevant statistical detail is available regarding the outcomes of the available antiepileptic therapies, but its interpretation[…][dx.doi.org]

  • 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] Ictal EEGs show sudden occipital discharges.[emedicine.com] About one third of patients never show occipital spikes.[emedicine.com]

  • Brain Neoplasm

    Stereotactic radiosurgery (SRS) using the Gamma Knife (GK) is now being increasingly utilized for the treatment of brain metastases. However, there are a few reported cases of SRS-induced brain neoplasms. We herein report the case of a Japanese woman with metastatic non-small cell lung cancer (NSCLC) harboring[…][ncbi.nlm.nih.gov]

  • Creutzfeldt Jakob Disease

    MRI found typical cortical hyperintensities in the occipital regions while rhythm slowing and sharp waves were seen in the occipital regions on EEG.[ncbi.nlm.nih.gov] 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]

  • 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]

  • Lennox-Gastaut Syndrome

    Review Article First Online: 09 November 2017 Abstract Lennox-Gastaut syndrome (LGS) is considered an epileptic encephalopathy and is defined by a triad of multiple drug-resistant seizure types, a specific EEG pattern showing bursts of slow spike-wave complexes or generalized paroxysmal fast activity, and[…][doi.org]

  • 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]
