22 Possible Causes for Parietal Sharp-and-Slow-Waves

  • Epilepsy

    Epilepsy is a brain disorder in which a person has repeated seizures over time. Seizures are episodes of uncontrolled and abnormal firing of brain cells that may cause changes in attention or behavior. Epilepsy occurs when changes in the brain cause it to be too excitable or irritable. As a result, the brain sends[…][]

    Continuum (Minneap Minn). 2015 Apr;21(2 Neuro-oncology):480-6. doi: 10.1212/01.CON.0000464183.35322.5f. Abstract Neurologists are often on the front lines of diagnosis for primary and metastatic brain tumors. Patients with brain tumors typically have multiple comorbidities and pain generators beyond headache,[…][]

  • Rolandic Epilepsy

    Benign Rolandic epilepsy or benign childhood epilepsy with centrotemporal spikes (BCECTS) is the most common epilepsy syndrome in childhood. Most children will outgrow the syndrome (it starts around the age of 3–13 with a peak around 8–9 years and stops around age 14–18), hence the label benign. The seizures,[…][]

  • Creutzfeldt Jakob Disease

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

  • Lennox-Gastaut Syndrome

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

  • Angelman Syndrome

    Angelman syndrome is a rare genetic disorder characterized by severe intellectual and developmental disability, sleep disorder, frequent and sometimes inappropriate laughter, seizures, jerky movements and ataxia. It is named after the British pediatrician, Dr. Harry Angelman, who first described it in 1965. Patients[…][]

  • Early Myoclonic Encephalopathy

    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,[…][]

  • Miller Dieker Syndrome

    Summary Epidemiology MDS is undoubtedly a rare condition with a reported estimate of 1 cases per 100 000 live births, although incidence and prevalence are probably higher. Clinical description Children with MDS present with severe developmental delay, usually have epilepsy, and feeding problems are common. The[…][]
