  • Panayiotopoulos Syndrome

    EEG showed right occipital high-amplitude sharp and slow-wave complexes followed by brief generalized discharges of slow waves.[ncbi.nlm.nih.gov] Generalized slowing is not seen except in postictal periods. Interictal EEG . A single routine EEG is normal in 10% of patients.[medlink.com] Both syndromes share similar classical inter-ictal EEG features with runs of occipital sharp and slow wave complexes which attenuate on eye opening (Panayiotopoulos, 1981[academic.oup.com]

Ohtahara syndrome is a neurological disorder characterized by seizures. The disorder affects newborns, usually within the first three months of life (most often within the first 10 days) in[…][web.archive.org]

  • Brain Neoplasm

    Continuum (Minneap Minn). 2015 Apr;21(2 Neuro-oncology):480-6. doi: 10.1212/01.CON.0000464183.35322.5f. Abstract Neurologists are often on the front lines of diagnosis for primary and metastatic brain tumors. Patients with brain tumors typically have multiple comorbidities and pain generators beyond headache,[…][ncbi.nlm.nih.gov]

  • Rolandic Epilepsy

    Benign Rolandic epilepsy or benign childhood epilepsy with centrotemporal spikes (BCECTS) is the most common epilepsy syndrome in childhood. Most children will outgrow the syndrome (it starts around the age of 3–13 with a peak around 8–9 years and stops around age 14–18), hence the label benign. The seizures,[…][en.wikipedia.org]

  • Creutzfeldt Jakob Disease

    Although MM2‐cortical‐type sCJD generally shows slow progression without myoclonus or periodic sharpwave complexes, the present patient showed a rapidly progressive clinical[dx.doi.org] 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[ncbi.nlm.nih.gov] A 76-year-old man was transferred to a tertiary neurology center with a clinical history of 6-month weight loss, cognitive disturbance, and nonspecific generalized weakness[ncbi.nlm.nih.gov]

  • Angelman Syndrome

    Angelman syndrome (AS) is a genetic disorder characterised by severe mental retardation, subtle dysmorphic facial features, a characteristic behavioural phenotype, epileptic seizures and EEG abnormalities. AS can be caused by various genetic mechanisms involving the chromosome 15q11-13 region. Neurophysiological[…][ncbi.nlm.nih.gov]

  • Early Myoclonic Encephalopathy

    Epileptic encephalopathy with suppression-burst in electroencephalography (EEG) can evolve into a few types of epileptic syndromes. We present here an unusual case of early myoclonic encephalopathy that evolved into migrating partial seizures in infancy. A female neonate initially had erratic myoclonus movements,[…][ncbi.nlm.nih.gov]

  • Miller Dieker Syndrome

    Summary Epidemiology MDS is undoubtedly a rare condition with a reported estimate of 1 cases per 100 000 live births, although incidence and prevalence are probably higher. Clinical description Children with MDS present with severe developmental delay, usually have epilepsy, and feeding problems are common. The[…][orpha.net]
