  • Creutzfeldt Jakob Disease

    OBJECTIVE: We aimed to redefine various periodic patterns (PPs) observed on electroencephalography (EEG) in patients with sporadic Creutzfeldt-Jakob disease (sCJD) using the[ncbi.nlm.nih.gov] Kunze, Clinical changes and EEG patterns preceding the onset of periodic sharp complexes in Creutzfeldt — Jakob disease, Acta Neurologica Scandinavica, 97, 2, (99-106), (2009[doi.org] It also became apparent that the duration could vary greatly ranging from weeks to several years as did the electroencephalographic (EEG) patterns that had the characteristic[doi.org]

  • Rolandic Epilepsy

  • Encephalopathy

    . • Effect depend on dose, and duration of exposure * Narcoleptics—slowing of alpha, increase in theta and delta activity and paroxysmal bursts of sharp and slow waves, these[slideshare.net] This EEG pattern is continuous and remains unchanged during both waking and sleeping states. Structural abnormalities can often be seen on cranial MRI.[orpha.net] […] such as triphasic waves, periodic discharges, NCSE, coma patterns (alpha, theta and spindle), burst suppression, or others were excluded from this investigation.[scielo.br]

  • Vascular Dementia

    Many of the previous studies of vascular dementia using proton magnetic resonance (MR) spectroscopy had been carried out on white matter. However, no proton spectroscopic data of the subcortical gray matter are available in such disease. We report two cases suffering from vascular dementia, with an unilateral[…][ncbi.nlm.nih.gov]

  • Periventricular Leukomalacia

    Abstract To describe the impact of periventricular leukomalacia (PVL) on gross motor function, data on 59 children (37 males, 22 females) with a gestational age (GA) of 34 weeks or less with cerebral palsy (CP) due to PVL grade I ( n 20), II ( n 13), III ( n 25), and IV ( n 1) were studied; (mean GA 29wk 4d [SD[…][doi.org]

  • Fragile X Syndrome

    Fragile-X syndrome (FXS) is a frequent genetic form of intellectual disability (ID). The main recurrent mutagenic mechanism causing FXS is the expansion of a CGG repeat sequence in the 5'-UTR of the FMR1 gene, therefore, routinely tested in ID patients. We report here three FMR1 intragenic pathogenic variants not[…][ncbi.nlm.nih.gov]

  • Benign Familial Infantile Epilepsy Type 4

    The EEG examination showed diffuse abnormal background activity, with sporadic isolated bilateral sharp waves over the occipital regions (a).[onlinelibrary.wiley.com] This is done by performing an electroencephalogram or EEG. This is a painless and non-invasive means of recording the patterns of electrical activity of the brain.[kcnq2cure.org] The EEG examination showed diffuse abnormal background activity, with sporadic isolated bilateral sharp waves over the occipital regions (a).[onlinelibrary.wiley.com]

  • Pyridoxine Dependency Syndrome

    The most noteworthy interictal pattern consists of bursts or runs of high voltage relatively bilaterally synchronous 1-4 Hz activity with intermixed spikes and or sharp waves[indianpediatrics.net] The typical EEG pattern is a consistent (wake and sleep) “suppression-burst” pattern with periods of diffuse amplitude suppression alternating with bursts of high amplitude[demosmedical.com] The most noteworthy interictal pattern consists of bursts or runs of high voltage relatively bilaterally synchronous 1-4 Hz activity with intermixed spikes and or sharp waves[indianpediatrics.net]
