54 Possible Causes for Focal Sharp-and-Slow-Waves, Nocturnal Seizure

  • Panayiotopoulos Syndrome

    Interictal EEG shows occipital spikes although multifocal spikes with high amplitude sharp-slow wave complexes at various locations can be present.[ncbi.nlm.nih.gov] seizures, tonic deviation of the eyes, and vomiting.[ncbi.nlm.nih.gov] Multifocal high voltage repetitive spikes or sharp and slow-waves are seen in 90% of patients; these often are present in different focal areas on sequential EEGs.[medlink.com]

  • Rolandic Epilepsy

    The EEG feature of sharp-slow waves originating from the rolandic region is the unifying feature.[epilepsygenetics.net] Secondary generalization of the nocturnal seizure is common.[epilepsy.com] Seizures usually occur infrequently as generalized nocturnal seizures characterized by a variety of minor tonic-clonic movements, often affecting only one side of the face[epilepsyontario.org]

  • Epilepsy

    Pathologic slowing, when localized, often correlates with focal brain lesions; when diffuse, slow activity often signifies an encephalopathy.[ncbi.nlm.nih.gov] Leu729ThrfsTer6) in TMTC3, encoding transmembrane and tetratricopeptide repeat containing 3, in four siblings with nocturnal seizures and ID.[ncbi.nlm.nih.gov] seizures from other non-epileptic nocturnal paroxysmal events, namely parasomnias.[ncbi.nlm.nih.gov]

  • Early Myoclonic Encephalopathy

    Inter-ictally, clusters of sharp-slow wave focal discharges maximum around the left Rolandic regions (left). They became continuous during natural sleep (right).[slideshare.net] Nocturnal epilepsy Progressive myoclonic epilepsy Reflex epilepsy Secondary reading epilepsy Seizure, myoclonic Seizures, myoclonic Severe myoclonic epilepsy in infancy Stress-induced[icd9data.com] […] dominant nocturnal frontal lobe epilepsy Late-onset childhood occipital epilepsy (Gastuat type) Epilepsy with myoclonic absences Epileptic encephalopathy with continuous[loyolamedicine.org]

  • Lennox-Gastaut Syndrome

    Interictal There may be focal or multifocal spike-and-wave or sharp-slow waves, with an anterior predominance.[epilepsydiagnosis.org] Tonic; atonic and atypical absences Myoclonic, atonic and myoclonic-atonic Tonic seizures Common and characteristic, diurnal and nocturnal Probably exclusion criterion (nocturnal[icnapedia.org] Those cases that appear nocturnally usually occur during the periods of slow-wave sleep in the latter part of the night.[epilepsyontario.org]

  • Miller Dieker Syndrome

    EEG patterns of two types are recognized - diffuse, atypical slow sharp/spike-and-wave complexes in long bursts activated by slow wave sleep or high amplitude fast spike/polyspike-and-wave[epilepsydiagnosis.org] Nocturnal frontal lobe seizures are common. Around 50% of patients report frightening visual hallucinations during their focal seizures.[epilepsydiagnosis.org] Epileptic spasms, atypical absences and focal seizures may also occur.[epilepsydiagnosis.org]

  • Ring Chromosome 20 Syndrome

    EEG patterns of two types are recognized - diffuse, atypical slow sharp/spike-and-wave complexes in long bursts activated by slow wave sleep or high amplitude fast spike/polyspike-and-wave[epilepsydiagnosis.org] Keywords: Medically intractable epilepsy, frontal lobe seizures, nocturnal seizures, non-convulsive status epilepticus, chromosomal testing, mosaic screening DOI: 10.3233[content.iospress.com] nocturnal seizures or non-convulsive status epilepticus.[en.wikipedia.org]

  • Benign Adult Familial Myoclonic Epilepsy

    Note the independent, bi-occipital sharp and slow wave complexes with eyes closed.[euroformhealthcare.biz] Most nocturnal seizures occur in stage 1 and stage 2 , which are moments of lighter sleep. Nocturnal seizures can also occur upon waking.[healthline.com] Benign Familial Neonatal seizures Perrine Plouin 8. Autosomal dominant nocturnal frontal lobe epilepsy Paolo Tinuper, Francesca Bisulli 9.[shorvon.eu]

  • Jacksonian Seizure

    Focal epileptiform discharges occur in secondarily generalized seizures. In absence seizures, spikes and slow waves appear at a rate of 3/sec.[meta-religion.com] Nocturnal Seizures : Nocturnal seizures are usually tonic-clonic.[epilepsywarriors.org] seizures » People who have experienced a traumatic brain injury in the past are at greater risk of focal onset seizures.[healthline.com]

  • Epilepsy with Continuous Spike-and-Slow-Waves during Sleep

    The EEG feature of sharp-slow waves originating from the rolandic region is the unifying feature.[euroepinomics.wordpress.com] Third stage (after months to usually 2 to 7 years) with remission of seizures and general improvement. Timing Seizures are often nocturnal.[epilepsy.com] From age 7, she had absence seizures with falling and rare nocturnal seizures. Waking EEG showed general- ized or left focal spike-wave discharges (Fig. 1B).[docslide.com.br]
