504 Possible Causes for Focal Spikes, Progressive Action Tremor, Temporal Focal Spikes

  • 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] EEG during drowsiness and sleep showing frequent bilateral synchronous/independent biphasic spikes followed by slow waves in the centro-temporal regions. 32.  Childhood/adolescent[slideshare.net] […] childhood epilepsy with centrotemporal spike -childhood epilepsy with occipital paroxysms Generalized epilepsies & synd.[enotes.tripod.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] Focal seizures began at 5 years and were refractory to medical treatment.[ncbi.nlm.nih.gov] (EEG) hallmark of focal-onset seizures is the focal interictal epileptiform spike or sharp wave.[emedicine.medscape.com]

  • West Syndrome

    Brain MRI revealed no abnormal findings although interictal EEG demonstrated left centro-parieto-temporal localized spike foci.[ncbi.nlm.nih.gov] A “leading” spike had a focal origin in all 42 type I spasms and involved the pre‐ or postcentral gyrus within 0.1 s in 37 of these spasms.[doi.org] At time they appear to be focal, and a few seconds later they seem to originate from multiple foci.[en.wikipedia.org]

  • Idiopathic Generalized Epilepsy

    Fragmented generalized spike-and-wave can appear focal or multi-focal but usually is not consistently seen in 1 area.[medlink.com] The EEG signature of IGE is bisynchronous, symmetric, and generalized spike-wave complex; although focal, irregular, and so called "fragments" of discharges are not uncommon[ncbi.nlm.nih.gov] The morphology of the focal spike-and-wave typically appears similar to the generalized spike-and-wave.
