502 Possible Causes for Focal Spikes, Occipital Focal 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] .  Previously called early-benign childhood seizures with occipital spikes  Childhood onset (peak 5 years).  Focal autonomic seizures or autonomic status epilepticus, frequently[slideshare.net] Benign Rolandic epilepsy benign childhood epilepsy with centrotemporal spikes benign focal epilepsy of childhood: Epilepsy characterized by partial (focal) seizures, often[childneurologyfoundation.org]

J.[doi.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]

  • Idiopathic Generalized Epilepsy

    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] Fragmented generalized spike-and-wave can appear focal or multi-focal but usually is not consistently seen in 1 area.[medlink.com] Other characteristic EEG features include polyspikes, polyspike-wave discharges, occipital intermittent rhythmic delta activity, and photoparoxysmal response.[ncbi.nlm.nih.gov]

  • 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]

    Photic stimulation is a recognized cortical precipitant of GSW ( Niedermeyer, 1996 ) and focal occipital spike and slow wave ( Ricci and Vigevano, 1993 ).[academic.oup.com] Although focal spikes can occur, if they consistently arise in 1 area, consider structural brain abnormality.
