[…] the previously shown linkage of absence epilepsy (AE) to 2q36, both in human and WAG/Rij absence rat models, a 160-kb region at 2q36 containing eight genes with expressions in the brain was targeted in a case-control association study involving 205 Turkish [ncbi.nlm.nih.gov]

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 complexes. [orpha.net]

An EEG test will usually show a pattern called generalised spike and slow wave activity, particularly if the child or young person is tired or has been sleep-deprived before the test. [epilepsy.org.uk]

Generalized 3-4 Hz spike or polyspike slow-wave complexes. Neuro Imaging: Not usually required. Mainly from other IGEs such as CAE or Juvenile Myoclonic Epilepsy (JME). At onset, both JAE and JME may present with GTCS. [pennsw.com.au]

The ictal EEG is characteristic, and usually has regular and symmetrical generalised discharges of 3–4 Hz “spike and slow” wave complexes, and may also have multiple spike and slow wave complexes (fig 1 ). 1 The background interictal EEG is usually normal [adc.bmj.com]

The 3 Hz spike and wave discharges are thought to reflect a synchronized thalamocortical network. T-type calcium channels in the thalamus are thought to be an important component in the epileptic circuit. [docneuro.com]

EEG shows classical generalized 3 Hz spike-and-slow-wave discharges. Response to appropriate pharmacological treatment is usually excellent, but relapses are probably unavoidable on drug withdrawal. [medlink.com]

An EEG in untreated individuals is typically abnormal with a specific EEG pattern, known as a 3-6 Hz generalized polyspike and wave discharge. An example of this condition is shown in the figure at the top of this page. [epilepsy.com]

Bursts of generalized polyspikes and waves (multiple spike-and-slow-wave complexes) may also be seen, [30] especially during sleep and in syndromes with older age of onset. [reference.medscape.com]

However, all affected individuals displayed classic JME symptoms with typical EEG traits of 4‐ to 4.5‐Hz generalized polyspike waves, further supporting the notion that EFHC1 mutations are associated with classic JME without pyknoleptic absences. 6 On [onlinelibrary.wiley.com]

Generalized polyspike-and-waves are the most characteristic electroencephalographic pattern. Usual neuroimaging studies show no abnormalities. Atypical presentations should be entertained, as they are likely to induce misdiagnosis. [scielo.br]
