158 Possible Causes for Central Focal Spikes, Jerk-Locked Premyoclonus Spikes, Progressive Action Tremor

  • Benign Adult Familial Myoclonic Epilepsy

    Usually, myoclonic tremor is the presenting symptom, characterized by tremulous finger movements and myoclonic jerks of the limbs increased by action and posture.[uniprot.org] , 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] […] cortical spikes detected by the jerk-locked back-averaging) ( Ikeda et al., 1990 ).[academic.oup.com]

  • Epilepsia Partialis Continua

    ) Cortical tremor is a form of rhythmic myoclonus, presenting as postural or action tremor in some patients with progressive myoclonus epilepsy (PME), 76, 77 in Angelman syndrome[clinicalgate.com] Structural MRI showed a region of focal cortical dysplasia (FCD) over the right central gyrus and lesions in the mesial frontal and occipital cortex secondary to perinatal[ncbi.nlm.nih.gov] Jerk-locked back averaging (JLA) of magnetoencephalogram disclosed a spike preceding the jerk localized at the hand motor area, whereas JLA of electroencephalogram revealed[ncbi.nlm.nih.gov]

  • 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]

  • Idiopathic Generalized Epilepsy

    Tonic status epilepticus (TSE) in patients with idiopathic generalized epilepsy (IGE) is not well recognized. The objective of this study is to report episodes of TSE in patients with IGE. We retrospectively reviewed the clinical and EEG evaluation of three IGE patients who presented TSE. The three patients had mainly[…][ncbi.nlm.nih.gov]

  • 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]

    PURPOSE: The aim of this study to evaluate the hippocampal, frontal and thalamic lobe functions in the early stage of the juvenile absence epilepsy (JAE) by magnetic resonance proton spectroscopy (MRS). METHOD: Fourteen patients with juvenile absence epilepsy with typical absence seizures and 10 healthy volunteer[…][ncbi.nlm.nih.gov]
