16 Possible Causes for Central Focal Spikes, Paroxysmal Activity - Spikes Central Bilaterally, Paroxysmal Activity - Spikes Temporal Bilaterally

  • Benign Adult Familial Myoclonic Epilepsy

    , multifocal, or bilateral distribution and time locked to sharp-wave or spike-wave discharges on the contralateral central areas. 34, 35 ENM has a wide etiological spectrum[clinicalgate.com] Between these bursts are inserted periods of variable duration without obvious paroxysmal discharges but with θ–wave activity of variable amplitude involving both central[neupsykey.com] […] disease, 29, 30 Down syndrome, and mitochondrial disorders. 31, 32, 33 Epileptic negative myoclonus (ENM) is characterized by brief (50 to 400 msec) muscle inhibitions with focal[clinicalgate.com]

  • Epilepsy

    In infancy, the EEG background was normal (1), showed diffuse (3) or focal slowing that was temporal (1) and in the left hemisphere (1), and showed focal (central, temporal[brain.oxfordjournals.org] ) discharges or generalized spike wave and polyspike wave activity.[brain.oxfordjournals.org] After infancy, the EEG background was normal (5), showed diffuse slowing (10) or focal slowing that was bilateral fronto-temporal (2) and left temporal (1).[brain.oxfordjournals.org]

  • Generalized Clonic or Tonic-Clonic Seizures

    ‘Contrary to popular folk belief, nothing should be placed in the mouth during the seizure. Severe injury could occur.’ Generalized tonic clonic seizures (grand mal seizures) are the most common and best known type of generalized seizure. They begin with stiffening of the limbs (the tonic phase), followed by jerking[…][epilepsynw.org]

  • Juvenile Myoclonic Epilepsy

    History Juvenile myoclonic epilepsy (JME) is diagnosed on the basis of clinical findings. Video-electroencephalography (EEG) monitoring of typical seizures is the criterion standard, but in the great majority of patients, a working diagnosis of probable JME is made on the basis of the clinical history, often with[…][emedicine.medscape.com]

  • Organic Brain Syndrome

    Abstract This study addresses the prevalence of organic brain syndrome (OBS) among long-term toluene-exposed rotagravure workers who are still working. The prevalence of OBS in 22 workers exposed to toluene for a minimum of 12 years and 19 unexposed control subjects, matched for age and employment status,[…][ncbi.nlm.nih.gov]

  • Encephalopathy

    Posterior reversible encephalopathy syndrome is an encephalopathy that can be clinically characterized by headache, altered mental status and/or seizures. Neuroimaging demonstrates usually reversible bilateral subcortical vasogenic occipital-parietal edema. Exact pathophysiology remains unclear but is commonly[…][ncbi.nlm.nih.gov]

  • Juvenile Absence Epilepsy

    We describe a 68-year-old woman who had typical absence seizures since 14 years of age. The absences were refractory to treatment and persisted into adulthood, with no seizure-free periods until seizure control at 59 years of age. After six years of being seizure-free, she presented with an episode[…][ncbi.nlm.nih.gov]

  • Uremic Encephalopathy

    BACKGROUND AND PURPOSE: Uremic encephalopathy is a metabolic disorder in patients with renal failure. The purpose of this study was to describe the MR imaging findings of uremic encephalopathy. MATERIALS AND METHODS: This study retrospectively reviewed MR imaging findings in 10 patients with clinically proved uremic[…][ncbi.nlm.nih.gov]
