671 Possible Causes for Progressive Action Tremor, Spike-and-Slow-Waves, 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] […] and slow wave seen in at least 85% of slow-wave sleep.  Characterized by a hallmark EEG presentation, called continuous spike and-wave during sleep (CSWS) or electrical[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] […] predominance, and multifocal spike-and-slow waves.[ncbi.nlm.nih.gov] Electroencephalography showed spike-slow waves and slow waves with mixed asynchronized spike waves originating from the frontal lobe during the sleep stage.[ncbi.nlm.nih.gov]

    , poly spike discharges." [2] The clonic phase EEG will show "high amplitude activity that is typically interrrupted by slow waves to create a spike-and-slow-wave pattern.[en.wikipedia.org] According to "Harrisons Manual of Medicine," the EEG during the tonic phase will show a "progressive increase in low-voltage fast wave activity, followed by generalized high-amplitude[en.wikipedia.org]

  • Juvenile Absence Epilepsy

    All patients had minimum twice EEG recordings and all had typical 3-Hz generalized spike and slow-wave discharges at least on one EEG.[ncbi.nlm.nih.gov] EEG shows classical generalized 3 Hz spike-and-slow-wave discharges.[medlink.com] Diagnostic methods Diagnosis relies on the clinical features and on electroencephalogram (EEG) recorded awake and during sleep, that displays a generalized 3-4 Hz spike-and-slow-wave[orpha.net]

[37] In hypokalemia, diffuse slow activity can be seen together with paroxysmal delta/theta activity, as well as focal paroxysms of sharp waves and spike-waves[neurologyindia.com] Intermittent bursts of high voltage slowing and spike and wave activity are noted, particularly in the frontal leads. 44 The EEG may show an initial deterioration after treatment[jnnp.bmj.com] ., frontal intermittent rhythmic delta activity (FIRDA), or spikes and sharp waves as well as spike-wave discharges in temporal regions.
