763 Possible Causes for Diffuse Slowing

  • Dementia

    In patients with delirium, the EEG shows a diffuse slowing of the background rhythm. An exception is patients with delirium tremens, where the EEG shows fast activity.[aafp.org] slow waves or epileptiform discharges on electroencephalogram Differentiating Delirium from Primary Psychiatric Disorder Certain signs and symptoms can help physicians distinguish[web.archive.org] slow waves or epileptiform discharges on electroencephalogram View/Print Table TABLE 4 Distinguishing Characteristics of Delirium, Dementia, Psychotic Disorders, and Depression[aafp.org]

  • Meningitis

    Serial electrodiagnostic testing demonstrated a rapidly progressive diffuse sensory motor axonopathy, and electroencephalogram findings progressed from generalized slowing[science.gov] The capabilities of flow-sensitive MRI, based on slow-flow magnetic resonance pulsing sequences or diffusion-weighted MRI, as an additional valuable diagnostic tool to identify[doi.org]

  • Acromegaly

    Pure somatotrope pituitary adenomas (60%) contain either cells rich in secretory granules that show diffuse immunostaining (such densely granulated somatotrope adenoma are[dx.doi.org] […] observed in older patients with slow disease progression) or cells poor in secretory granules with scattered immunolabelling (sparsely granulated somatotrope adenomas are[dx.doi.org]

  • Continuous Spike-and-Slow-Waves during Sleep

    The EEG findings were characterized by nearly continuous ( 85%) diffuse slow spike and wave activity in two patients, and localized to one hemisphere in two other cases during[scielo.br] , slow spike-wave activity(1).[moh-it.pure.elsevier.com] EEG showed multifocal (predominantly posterior), diffuse and generalized spike-waves, which were continuous during slow-wave sleep, with a spike-wave index 94% [Figure 1].[jpgmonline.com]

Neuroimaging demonstrated normal findings in 10 children.[ncbi.nlm.nih.gov] Interictal electroencephalography in chronic phase in 3 of 4 patients identified diffuse slowing of cortical rhythm, in 2 cases – epileptiform activity in the form of a spike-and-wave[ingentaconnect.com] Follow-up magnetic resonance imaging was performed in 3 cases: 2 were normal and 1 had mild diffuse cortical atrophy.[ingentaconnect.com]
