74 Possible Causes for Active Generalized Spikes and Polyspikes, Small Hippocampi

  • Generalized Clonic or Tonic-Clonic Seizures

    Simple Partial Seizures Simple partial seizures only affect a small part of the brain, usually the temporal lobes or hippocampi, and are usually brief in duration, lasting[efmny.org] Other information is obtained from tests such as: EEG (electroencephalogram) : people with EGTCS have normal EEG background and generalized spike wave or polyspike wave activity[epilepsy.com]

  • Benign Adult Familial Myoclonic Epilepsy

    The EEG shows generalized polyspike and spike-and-wave discharges, frequently precipitated by photic stimulation.[clinicalgate.com] We included patients with single or multiple generalised seizures, in whom at least one active EEG showing a generalised spike and wave or polyspike and wave pattern was obtained[jnnp.bmj.com] Background EEG activity becomes progressively slower. 53 Cortical reflex myoclonus is common to all PME syndromes, in which it is manifested with the classic combination of[clinicalgate.com]

  • Idiopathic Generalized Epilepsy

    Other characteristic EEG features include polyspikes, polyspike-wave discharges, occipital intermittent rhythmic delta activity, and photoparoxysmal response.[ncbi.nlm.nih.gov] The abnormalities included generalized spike-wave and/or spike-polyspike morphology in majority.[annalsofian.org] We included patients with single or multiple generalised seizures, in whom at least one active EEG showing a generalised spike and wave or polyspike and wave pattern was obtained[jnnp.bmj.com]

    (E) Coronal views of the hippocampi at 2 months show bilateral small hippocampi with left hippocampal malrotation.[neurology.org] However, it may show polyspike activity or generalized spike wave pattern later on.[neurologyindia.com] At 4 months, MRI brain revealed bilateral small hippocampi with a dysmorphic corpus callosum.[neurology.org]

  • West Syndrome

    IARS2 encodes isoleucine-tRNA synthetase, which is aclass-1 amino acyl-tRNA synthetase. IARS2 mutations are reported to cause Leigh syndrome or cataracts, growth hormone deficiency, sensory neuropathy, sensorineural hearing loss, and skeletal dysphasia syndrome (CAGSSS). To our knowledge, IARS2 mutations and[…][ncbi.nlm.nih.gov]
