184 Possible Causes for Focal Sharp-Waves or Spikes Occipital or Temporal, Paroxysmal Activity - Sharp-Waves, Temporal Focal Spikes

  • 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] […] background, diffusemultifocal sharp waves and sharp waves-slow waves; paroxysmal fast activity Neurological examination mild diffuse hypotonia, mild ataxia with wide based[ncbi.nlm.nih.gov] 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]

  • Benign Adult Familial Myoclonic Epilepsy

[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] ., frontal intermittent rhythmic delta activity (FIRDA), or spikes and sharp waves as well as spike-wave discharges in temporal regions.

  • Lennox-Gastaut Syndrome

    “Pseudo Lennox syndrome” can be distinguished by the persistently normal background, sleep activation of central-temporal spikes, and lack of tonic seizures.[childneurologyfoundation.org] Interictal EEG showed findings characteristic of LGS: generalized slow spike-wave complexes, multifocal sharp waves, generalized polyspikes and paroxysmal fast activity during[ncbi.nlm.nih.gov] In fact, 10/24 cases showed normal sleep transients with presence of symmetric vertex sharp waves in stage 1 non-REM sleep and also symmetric and well structured sleep spindles[omicsonline.org]

  • Rolandic Epilepsy

    focal or generalized spikes and waves.[ncbi.nlm.nih.gov] The EEG has centro-temporal spikes with accentuation in sleep – therefore a sleep deprived or sleep EEG is important if the awake EEG is normal.[pennsw.com.au] Previous names for childhood epilepsy with centro-temporal spikes Benign rolandic epilepsy Benign rolandic epilepsy of childhood (BREC) Benign epilepsy with centrotemporal[epilepsy.org.uk]

  • Juvenile Myoclonic Epilepsy

    spikes immediately preceding bisynchronous discharges, and subsequently to temporal intermittent rhythmic delta activity and temporal lobe-onset seizures.[ncbi.nlm.nih.gov] In this rare case of coexistent primary generalised epilepsy and focal epilepsy, the epileptic networks of the two forms of epilepsy appear to overlap.[ncbi.nlm.nih.gov] […] was an electrographic evolution from the typical generalised epileptiform patterns, characteristic of juvenile myoclonic epilepsy, to the novel appearance of interictal temporal[ncbi.nlm.nih.gov]
