179 Possible Causes for Multifocal Spikes, Paroxysmal Activity - Spikes Temporal Bilaterally, 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]

  • Epilepsy

    […] predominance, and multifocal spike-and-slow waves.[ncbi.nlm.nih.gov] Electroencephalography showed multifocal spikes over the right frontal, temporal and parietal regions. The seizure frequency decreased dramatically after tumorectomy.[ncbi.nlm.nih.gov] Inter-ictal multifocal spikes or sharp and slow waves in nearly all EEGs.[epilepsy.com]

  • West Syndrome

    Interictal The background EEG is often highly disorganized with high voltage irregular slow waves intermixed with multifocal spikes and polyspikes, this is termed 'hypsarrhythmia[epilepsydiagnosis.org] The interictal EEG pattern is described as hypsarrhythmic as it is characterised by asynchronous and high-amplitude slow waves and multifocal spikes.[orpha.net]

  • Benign Adult Familial Myoclonic Epilepsy

    Note the high-amplitude, disorganized slow activity with multifocal spikes with an electrodecremental response.[euroformhealthcare.biz] Cortical myoclonus is more commonly encountered in a multifocal form, presenting with multifocal spike discharges.[neupsykey.com] […] with emesis.  Interictal EEG with shifting or multifocal high- amplitude spikes, often with occipital predominance.  Favorable outcome with remission in 1–2 years and normal[slideshare.net]

  • Myoclonic-Astatic Epilepsy

    Interictal EEG revealed generalized irregular multiple spikes-and-waves with focal or multifocal accentuations.[ncbi.nlm.nih.gov] ; LTG, lamotrigine; M, myoclonic seizure; MA, myoclonic-astatic seizure; MF, multifocal spikes; PHT, phenytoin; PSW, diffuse polyspike and wave complexes; SBA, slowing of[omicsonline.org] […] and waves, photosensitivity, 4-7/sec rhythms), no multifocal EEG abnormalities (but often pseudofoci).[ncbi.nlm.nih.gov]

  • 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]

  • Juvenile Absence Epilepsy

    Background activity is often abnormal, reflecting the diffuse or multifocal underlying encephalopathy of symptomatic generalized epilepsy.[reference.medscape.com] Slow spike-and-wave discharges (2.5 Hz). This is an interictal pattern in a child with seizures and developmental delay.[reference.medscape.com] The clinical correlation of generalized spike-and-wave complexes with clinical seizures is not as clear-cut as in typical absence seizures.[reference.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]
