  • Juvenile Myoclonic Epilepsy

    We applied dipole modeling and brain distributed source analysis to find current sources comprising spikes and slow waves of polyspike and wave complexes (PSWC) in patients[ncbi.nlm.nih.gov] […] characterized by abrupt, repetitive, stereotyped and involuntary movements (motor tics) or sounds (phonic tics).[omicsonline.org] slow wave discharges.[en.wikipedia.org]

  • Epilepsy

    waves.[ncbi.nlm.nih.gov] It is characterized by recurrent seizures, which are brief episodes of involuntary movement that may involve a part of the body (partial) or the entire body (generalized),[web.archive.org] Generalized polyspike-slow wave in EEG was common to see in myoclonic seizure and can help to make the classification.[ncbi.nlm.nih.gov]

  • Idiopathic Generalized Epilepsy

    […] and slow waves during clonic phase 70% are seizure -free under treatment In some cases, no medical therapy is necessary avoid triggers Epilepsy with myoclonic-atonic seizures[amboss.com] Panayiotopoulos et al. (1994) [21] observed that 51.5% of patients had spike/multiple spike-slow wave discharges.[annalsofian.org] Generalized spike-and-wave or polyspike-and-wave is seen in the interictal EEG. Half of the patients have these abnormalities only in sleep. Caution.[medlink.com]

  • 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] They are characterized by single or repetitive, bilateral, abrupt, symmetric, arrhythmic, involuntary movements, predominantly involving the shoulders and arms; however, they[scielo.br] The EEG has generalized spike or polyspike slow-wave complexes. JAE is a lifelong disorder, although seizures can be controlled in 70% to 80% of patients.[pennsw.com.au]

  • Benign Adult Familial Myoclonic Epilepsy

    […] and slow-wave complexes at 3 Hz associated with myoclonus.  Interictal EEG is variable and ranges from normal to background slowing and generalized spike and slow-wave activity[slideshare.net] There is a presentation of clinically-focused information regarding the full spectrum of neurological and psychiatric conditions characterized by involuntary movements.[books.google.it] They also can include involuntary movements.[healthline.com]

  • Absence Seizure

    Ictal - EEG is of slow (less than 2.5 Hz) spike and slow wave.[en.wikipedia.org] Other associated symptoms that may be present include Lip smacking or chewing movements of the mouth Involuntary movement of hands Finger rubbing Fluttering of eyelids Stopping[medindia.net] 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[emedicine.medscape.com]

  • Generalized Clonic or Tonic-Clonic Seizures

    […] generalized high-amplitude, 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[en.wikipedia.org] movements Blepharospasm Limb ataxia Pontocerebellar atrophy Parkinsonism EEG with polyspike wave complexes Lafora bodies Morning myoclonic jerks Scoliosis Delayed speech[mendelian.co] . • Ictal EEG consists of “Fast activity” (10 Hz or more) and slow waves, with an occasional spike-and-wave pattern. • The EEG interictal expression is of “spike-and-wave[medlink.com]

  • Tonic-Clonic Seizure

    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] This report implies that damage to the BG and/or its connections might cause seizure-like involuntary movement.[ncbi.nlm.nih.gov] […] generalized high-amplitude, 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[en.wikipedia.org]

  • West Syndrome

    […] and slow-wave activity ( Gibbs and Gibbs 1952 ).[medlink.com] Tourette Syndrome (TS) is a life-long inherited neuropsychiatric disorder that causes involuntary movements and sounds in patients.[uhn.ca] Interictal The background EEG is often highly disorganized with high voltage irregular slow waves intermixed with multifocal spikes and polyspikes, this is termed 'hypsarrhythmia[epilepsydiagnosis.org]

  • Juvenile Huntington Disease

    Epileptiform discharges include generalized polyspike and slow-wave complex, spike and slow-wave complex, multifocal spikes and focal spikes.[e-jmd.org] Physical symptoms are present alongside the cognitive symptoms, and tend to get worse in the more intermediate stages of the disease: In early stages, small involuntary movements[info.isabelhealthcare.com] Summary of HD symptoms that require treatment: • Movement disorder Involuntary movements Incoordination of voluntary movements Rigidity/dystonia Oral-motor dysfunction. •[pediatricneurosciences.com]
