262 Possible Causes for Focal Polymorphic Delta Slowing, Occipital Slowing

  • Stroke

    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] Some epileptic focus can produce irregular focal slowing, associated or not with structural lesions, as well as postictal slowing after a focal seizure 6.[scielo.br] A nonrhythmic, temporal intermittent polymorphic delta activity (TIPDA) may occur interictally in patients with temporal and extratemporal epilepsy with an equal frequency[scielo.br]

  • Migraine

    Strongly associated with the aura many migraineurs get, this slow wave of abnormal neuronal excitation usually begins in the occipital lobe at the back of the brain, and spreads[sciencemag.org]

  • Traumatic Brain Injury

    We report on a patient with traumatic brain injury who showed motor recovery concurrent with recovery of injured corticofugal tracts (CFTs), diagnosed by diffusion tensor tractography (DTT). Four weeks after onset, when the patient started rehabilitation, he showed severe weakness of both upper and lower[…][ncbi.nlm.nih.gov]

  • Cerebral Hemorrhage

  • Brain Neoplasm

    RATIONALE AND OBJECTIVES: To compare differences in diffusion tensor imaging (DTI) and dynamic susceptibility-weighted contrast-enhanced (DSC) magnetic resonance (MR) perfusion imaging characteristics of recurrent neoplasm and radiation necrosis in patients with brain tumors previously treated with radiotherapy[…][ncbi.nlm.nih.gov]

  • Malignant Glioma

    At present, there is no uniform consensus on the treatment of recurrent glioblastoma, especially the re-irradiation dose and temozolomide (TMZ) dose. The literature on the treatment of recurrent glioblastoma (GBM) by conventionally fractionated stereotactic radiotherapy (CFRT) is even rarer. A 44-year-old woman[…][ncbi.nlm.nih.gov]

  • Postictal State

    Figure 1: Electroencephalogram (EEG): Diffuse slow wave activity in theta frequency of 5-6 Hz.[jneuro.com] […] demonstrated an increased signal intensity in right temporal lobe, which was more prominent in the insular cortex, and asymmetrical changes of intensity in the right parietal-occipital[jneuro.com]

  • 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]

  • Transient Ischemic Attack

    A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by loss of blood flow (ischemia) in the brain, spinal cord, or retina, without tissue death (infarction). TIAs have the same underlying mechanism as ischemic strokes. Both are caused by a disruption in blood flow to the brain, or[…][en.wikipedia.org]
