  • Epilepsy

    waves.[] 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),[] EEG recordings showed a variety of changes: generalized spike wave and polyspike wave activity, focal discharges, focal or diffuse slowing or were normal.[]

  • 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[] […] characterized by abrupt, repetitive, stereotyped and involuntary movements (motor tics) or sounds (phonic tics).[] Each SWD was divided into six distinct temporal phases: spike onset, spike peak, slow-wave onset, slow-wave ascending, slow-wave peak, and slow-wave descending phases.[]

  • 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[] Panayiotopoulos et al. (1994) [21] observed that 51.5% of patients had spike/multiple spike-slow wave discharges.[] 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.[]

  • Juvenile Huntington Disease

    Epileptiform discharges include generalized polyspike and slow-wave complex, spike and slow-wave complex, multifocal spikes and focal spikes.[] 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[] Summary of HD symptoms that require treatment: • Movement disorder Involuntary movements Incoordination of voluntary movements Rigidity/dystonia Oral-motor dysfunction. •[]

  • 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.[] They are characterized by single or repetitive, bilateral, abrupt, symmetric, arrhythmic, involuntary movements, predominantly involving the shoulders and arms; however, they[] […] variations between the spike/multispike-slow-wave relationships in generalized discharges of spike-polyspike-slow waves. (3) Predominantly brief discharges (shorter than[]

  • 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[] There is a presentation of clinically-focused information regarding the full spectrum of neurological and psychiatric conditions characterized by involuntary movements.[] They also can include involuntary movements.[]

  • Toxic Encephalopathy

    Some the most common symptoms of toxic encephalopathy include: Altered mental status Increased irrationality Memory loss Seizures Fatigue Involuntary movements Depression[] movements (parkinsonism), fatigue, seizures, arm strength problems, and depression. [1] A paper by Feldman and colleagues described neurobehavioral effects in a 57-year-old[] movements Depression Toxic encephalopathy can cause permanent brain damage and is considered irreversible in many cases.[]

  • 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[] movements Blepharospasm Limb ataxia Pontocerebellar atrophy Parkinsonism EEG with polyspike wave complexes Lafora bodies Morning myoclonic jerks Scoliosis Delayed speech[] movements Plagiocephaly Athetosis Sarcoma Abnormal lung lobation Abnormality of the upper limb Duodenal atresia Acute leukemia Multiple renal cysts Abnormality of the skull[]

  • West Syndrome

    […] and slow-wave activity ( Gibbs and Gibbs 1952 ).[] Tourette Syndrome (TS) is a life-long inherited neuropsychiatric disorder that causes involuntary movements and sounds in patients.[] We did one with Jack (T21) as an infant for atyipical movement, but it was diagnosed as stereotypy.[]

  • Early Infantile Epileptic Encephalopathy Type 3

    […] paroxysms of polyspikes or spikes-slow waves.  Ictal EEG  Varies according to seizure type. 16.[] movements AD 4 GRIN2B 138252 mental retardation- 6; early infantile epileptic encephalopathy 27 AD 19 GUF1 617064 early infantile epileptic encephalopathy, 40 AR 3 HCN1 602780[] West Syndrome (WS) aka as infantile spasms with hypsarrhythmia, EEG abnormality with asynchronous very high amplitude, irregular, continuous multifocal spike an slow wave[]
