72 Possible Causes for 'Eye of the Tiger' Sign on MRI, Jerk-Locked Premyoclonus Spikes, Slow-Frequency High-Amplitude Waves with High-Frequency Polyspikes

  • Benign Adult Familial Myoclonic Epilepsy

    T2 weighted brain MRI shows an ”eye of the tigersign corresponding to pallidal hypointensity with a high signal center.[neuroweb.us] […] cortical spikes detected by the jerk-locked back-averaging) ( Ikeda et al., 1990 ).[academic.oup.com] spikes detected by the jerk-locked back averaging (JLA) method), and a good response to antiepileptic drugs. 2 BAFME was first reported in 1990 in the Japanese population[nature.com]

  • Hallervorden-Spatz Syndrome

    Iron deposition in conjunction with destruction of the globus pallidus gives rise to the characteristic eye-of-the-tiger sign in MRI.[ncbi.nlm.nih.gov] […] of the tiger" sign.[ncbi.nlm.nih.gov] It has been postulated that pantothenate kinase 2 mutations underlying all cases of classic Hallervorden-Spatz syndrome are always associated with the eye-of-the-tiger sign[ncbi.nlm.nih.gov]

  • Epilepsy

    Focal cortical dysplasia is a common cause of medically refractory epilepsy in infancy and childhood. We report a neonate with seizures occurring within the first day of life. Continuous video-EEG monitoring led to detection of left motor seizures and a right frontal EEG seizure pattern. Brain MRI revealed a lesion[…][ncbi.nlm.nih.gov]

  • Juvenile Myoclonic Epilepsy

    Juvenile myoclonic epilepsy (JME) is a type of epilepsy that starts in in childhood or the teen years. People who have it wake up from sleep with quick, jerking movements of their arms and legs. These are called myoclonic jerks. Even if you don’t have epilepsy, you’ve probably had these jerks that jolt you awake,[…][webmd.com]

  • 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]

  • Myoclonic-Astatic Epilepsy

    Abstract The EEG of 38 patients suffering from primary generalized myoclonic astatic epilepsy since early childhood is studied in late stages of the disease. Spectral analysis shows that parietal 4-7 cps rhythms (theta rhythms) which are typical of the EEG in the early stages of the disorder can still exist in the[…][ncbi.nlm.nih.gov]

  • Juvenile Absence Epilepsy

    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]
