950 Possible Causes for EEG Slowing, Focal Polymorphic Delta Slowing, Generalized Slow Activities in Bifrontal Distribution

  • Stroke

    Deep Belief Networks Based Brain Activity Classification Using EEG from Slow Cortical Potentials in Stroke.[dergipark.org.tr] In some cases, focal slow activity may presents as focal and irregular slow activity in the delta frequency, receiving the designation of polymorphic delta activity (PDA)[scielo.br] Abnormal EEG was found in 40 patients (58%) and was associated with higher age (p 0.021). The most common EEG pathology was focal slowing (30; 43.5%).[ncbi.nlm.nih.gov]

  • Migraine

    Abstract Acute confusional migraine (ACM) shows typical electroencephalography (EEG) patterns of diffuse delta slowing and frontal intermittent rhythmic delta activity (FIRDA[ncbi.nlm.nih.gov] EEG was normal at the beginning of visual aura.[ncbi.nlm.nih.gov] After 15minutes, posterior slow waves appeared over the migrainous hemisphere, spreading progressively towards anterior regions: first the central region (5minutes after onset[ncbi.nlm.nih.gov]

  • Traumatic Brain Injury

    The frequency of alexithymia and the proportion of cases reporting low emotional empathy after traumatic brain injury (TBI) were compared with a control group. The study also examined the relationship between alexithymia and emotional empathy, controlling for the influence of cognitive ability, severity of head[…][oadoi.org]

  • Cerebral Hemorrhage

    Intracerebral hemorrhage is a rare event during pregnancy that can result in serious morbidity and mortality for the mother and infant. In this article, we describe a case involving a multiparous woman at 34 weeks gestation who presented with a 5-cm intracerebral bleed. Within 2 hours of presenting, she underwent[…][ncbi.nlm.nih.gov]

  • Brain Neoplasm

    The clinical and radiologic manifestation of neurocysticercosis are varied. Since the introduction of anticysticercal drugs, surgery is only rarely needed in treatment. During the last 2 years, we have encountered two patients with minimal symptomatology whose cerebral CT and magnetic resonance studies demonstrated[…][ncbi.nlm.nih.gov]

  • Malignant Glioma

    Int J Mol Sci. 2017 Feb 10;18(2). pii: E350. doi: 10.3390/ijms18020350. Author information 1 Institute of Life Sciences, Chongqing Medical University, 1 Yixueyuan Road, Yuzhong District, Chongqing 400016, China. yingying_shao1226@outlook.com. 2 Department of Clinical Pharmacology, Xiangya Hospital, Central South University,[…][ncbi.nlm.nih.gov]

  • Brain Concussion

    A brain concussion is a still incompletely defined syndrome of traumatic brain injury (TBI) that causes a spectrum of symptoms without evident structural damage to the brain. A headache, cognitive deficits, emotional instability, sleep disturbances, and an overall change in mental state after trauma are highly[…][symptoma.com]

  • Epilepsy

    Her EEG showed slow background with continuous occipital small spikes and photosensitivity.[ncbi.nlm.nih.gov] EEG findings showed that slow background activity was significantly common among patients with EP (P 0.009).[ncbi.nlm.nih.gov] Electroencephalography (EEG) showed progressively slowed background activity and sporadic generalized spike-and-wave discharges.[ncbi.nlm.nih.gov]

  • Astrocytoma

    […] multiforme.[1] Diagnosis[edit] A continuous EEG recording of the brain's electrical activity may help to identify and localize seizure activity, especially in children.[en.wikipedia.org] However, they are low-grade tumors, with a slow rate of growth, so patients commonly survive longer than those with otherwise similar types of brain tumours, such as glioblastoma[en.wikipedia.org]

  • Meningoencephalitis

    The diffuse slowing seen on EEG and seizure activity suggest that cerebral cortex was affected by the meningoencephalitis.[jamanetwork.com] Electroencephalogram (EEG): Frequently abnormal (diffuse slowing with periodic discharges) in chronic and acute HSE and can sometimes help to determine the localisation in[patient.info] Continuous EEG monitoring in the neurologic intensive care unit showed generalized background slowing and frequent spike-and-wave activity.[jamanetwork.com]
