90 Possible Causes for EEG Periodic Complexes

  • Creutzfeldt Jakob Disease

    Extrapyramidal muscular rigidity, myoclonus, and characteristic periodic electroencephalographic (EEG) complexes were observed comparatively late in the illness, and some[] Subsequent MRI findings of symmetrical lesions in the basal ganglia (nucleus caudatus, putamen) on the 13th week and EEG with periodic sharp wave complexes (PSWC) in frontal[] Periodic sharp wave complexes every 1 to 2 seconds over slowed background were found on EEG, and MRI showed cerebellar and bifrontal cortical T2/FLAIR/DWI hypersignal without[]

  • Subacute Sclerosing Panencephalitis

    The diagnosis of SSPE is based on characteristic clinical and EEG findings (periodic complexes) and demonstration of elevated antibody titres against measles in cerebrospinal[] Measles antibodies were positive in CSF and the EEG showed slow periodic complexes. This unusual radiological presentation has never been described in SSPE.[] EEG shows periodic complexes with high-voltage diphasic waves occurring synchronously throughout the recording.[]

  • Temporal Lobe Epilepsy

    Periodic limb movement disorder. Tardive dyskinesia. Panic attacks.[] May cause behavioural changes with vocalisations and complex motor and sexual automatisms.[] In differentiating from TLE, may need electroencephalograph (EEG) localisation. Excessive daytime somnolence - eg, due to a sleep apnoea or narcolepsy.[]

  • Status Epilepticus

    However, subtle status, as in complex partial or absence status, may necessitate an electroencephalogram (EEG) for diagnosis.[] EEG Neurosci. 37, 50–53 (2006). 138. Cockerell, O. C., Walker, M. C., Sander, J. W. & Shorvon, S. D. Complex partial status epilepticus: a recurrent problem. J. Neurol.[] The EEG is not only used for initial diagnosis, but is often left running for longer periods to monitor response to treatment.[]

  • Juvenile Myoclonic Epilepsy

  • Focal Onset Impaired Awareness Seizure

    Abstract We describe a patient in whom the only electrographic manifestation of a complex partial seizure recorded by video-EEG telemetry was periodic lateralized epileptiform[]

  • Versive Seizure

A.[] (A) Seizure (Sz) onset with low-voltage fast activity emerging from periodic spiking in the mesial temporal contacts. (B) Sample EEG from early seizure.[] […] recording during a temporal lobe complex-partial seizure.[]

  • Benign Adult Familial Myoclonic Epilepsy

    EEG consists of complex bursts of spikes and sharp waves , with periods of discontinuity; and the burst-suppression pattern, which may later evolve into a hypsarrhythmia pattern[] The onset is typically within the neonatal period, but before 3 mo of age.[]

  • Autistic Disorder

    Scalp video-EEG recordings revealed an epileptic encephalopathy with generalized slow spike-and-wave complexes alternating with electrodecremental periods, which generally[]
