63 Possible Causes for Focal Polymorphic Delta Slowing, Generalized Slow Activities in Bifrontal Distribution, Rhythmic Slowing Frontal

  • 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

    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]

  • Traumatic Brain Injury

    Pediatric head injuries are common and may present with varying degrees of altered mental status in children. The approach to evaluation, diagnosis, treatment, and prevention of further injury is important in achieving good health outcomes after a head injury. In this article, we review the pathophysiology,[…][ncbi.nlm.nih.gov]

  • 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

    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]

  • 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]

  • Astrocytoma

    A 41-year-old man presented to us with left arm and leg weakness and mild word finding difficulties. His preoperative magnetic resonance imaging (MRI) demonstrated abnormal T1 and T2 signal changes in the right temporal lobe and basal ganglia, indicative of possible glioma. An awake craniotomy for right temporal[…][ncbi.nlm.nih.gov]
