264 Possible Causes for 3-4 Hz Spikes, Generalized Asynchronous Slow-Waves, Urine Organic Acids Abnormal

  • West Syndrome

    Urine organic acids, amino acids and serum biotinidase are done. CT or MRI scan of the brain is done before the treatment is started.[epainassist.com] Hypsarrhythmia represents a completely chaotic and disorganized background pattern consisting of high amplitude slow waves and spikes that are asynchronous, non-rhythmic,[web.archive.org] Interictal EEG displays diffuse and asynchronous high voltage spikes and slow waves suggesting the hypsarrhythmic pattern. B.[bmcneurol.biomedcentral.com]

  • Epilepsy

    […] to 8 years of age, in an otherwise apparently healthy child. 3 The classic electroencephalogram (EEG) shows generalized spike-wave bursts (of 3 Hz) with normal background[doi.org] Hz Spike and Wave Discharges, Epilepsia, 31, 5, (557-566), (2007).[doi.org] […] childhood-onset epilepsy, making it the most common form of pediatric epilepsy. 1,2 The syndrome is characterized by daily frequent but brief staring spells, typically beginning at 4[doi.org]

  • Benign Adult Familial Myoclonic Epilepsy

    Massa et al. identified the following EEG characteristics as predictive of a "complicated" course: intermittent slow wave focus, multiple, asynchronous spike wave foci, spike[euroformhealthcare.biz] Childhood absence epilepsy with tonic-clonic seizures and electroencephalogram 3-4-Hz spike and multispike-slow wave complexes: linkage to chromosome 8q24.[reference.medscape.com] Her EEG showed 34 Hz spike and wave discharges. She had a daughter with childhood absence epilepsy, and two sisters and a cousin with seizures (fig 2 , family 1).[jnnp.bmj.com]

  • Brain Concussion

    A brain concussion is a still incompletely defined syndrome of traumatic brain injury (TBI) that causes a spectrum of symptoms without evident structural damage to the brain. A headache, cognitive deficits, emotional instability, sleep disturbances, and an overall change in mental state after trauma are highly[…][symptoma.com]

    OBJECTIVE: The aims of this study were to determine the prevalence and describe the importance of alcohol screening for all patients with traumatic brain injury (TBI) and examine the relationship between gender, age, Abbreviated Injury Scale (AIS), emergent decompressive craniectomy, Glasgow Coma Scale (GCS) from[…][ncbi.nlm.nih.gov]

  • Absence Seizure

    In electroencephalography (EEG), generalized 3-4 Hz spike and slow wave complexes indicate an absence seizure.[symptoma.com] Childhood absence epilepsy with tonic-clonic seizures and electroencephalogram 3-4-Hz spike and multispike-slow wave complexes: linkage to chromosome 8q24.[emedicine.com] 4 Hz spike-and-slow-wave complexes on EEG. [6] In childhood absence epilepsy, seizures are frequent and brief, lasting just a few seconds (pyknoleptic).[emedicine.com]

  • Generalized Clonic or Tonic-Clonic Seizures

    The EEG shows generalised spike and wave discharges of 3 to 4 Hz and some with photic sensitivity. This is potentially a lifelong epilepsy.[pennsw.com.au]

  • Juvenile Myoclonic Epilepsy

    Interictal electroencephalography (EEG) in JME shows interictal epileptiform discharges such as generalized spikes, polyspikes, bilateral-synchronous 4-6/s spike-wave complexes[go.galegroup.com] Myoclonic jerks appear to be time-locked to generalized 3-5 Hz spike-and wave complexes [8]. Photoparoxysmal response was seen in 40% of patients.[go.galegroup.com]
