14 Possible Causes for Focal Sharp-Waves, Focal Sharp-Waves or Spikes Occipital or Temporal, Paroxysmal Activity - Sharp-Waves

  • Epilepsy

    (EEG) hallmark of focal-onset seizures is the focal interictal epileptiform spike or sharp wave.[emedicine.medscape.com] […] background, diffusemultifocal sharp waves and sharp waves-slow waves; paroxysmal fast activity Neurological examination mild diffuse hypotonia, mild ataxia with wide based[ncbi.nlm.nih.gov] The cellular neurophysiologic correlate of an interictal focal epileptiform discharge in single cortical neurons is the paroxysmal depolarization shift (PDS).[emedicine.medscape.com]

  • 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]

  • Creutzfeldt Jakob Disease

    Sporadic Creutzfeldt-Jakob disease (sCJD) mainly occurs in the elderly, with the peak age of onset ranging from 55 to 75 years. The symptoms of sCJD are not unique, and laboratory tests such as magnetic resonance imaging (MRI), electroencephalogram (EEG) and cerebrospinal fluid (CSF)14-3-3 protein have low[…][ncbi.nlm.nih.gov]

  • 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]
