12 Possible Causes for Generalized Asynchronous Slow-Waves

  • 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]

  • Traumatic Brain Injury

    Cochrane Database of Systematic Reviews Background Raised intracranial pressure (ICP) is an important complication of severe brain injury, and is associated with high mortality. Barbiturates are believed to reduce ICP by suppressing cerebral metabolism, thus reducing cerebral metabolic demands and cerebral blood[…][doi.org]

  • Epilepsy

    Epilepsy is a brain disorder in which a person has repeated seizures over time. Seizures are episodes of uncontrolled and abnormal firing of brain cells that may cause changes in attention or behavior. Epilepsy occurs when changes in the brain cause it to be too excitable or irritable. As a result, the brain sends[…][medlineplus.gov]

  • West Syndrome

    Hypsarrhythmia represents a completely chaotic and disorganized background pattern consisting of high amplitude slow waves and spikes that are asynchronous, non-rhythmic,[web.archive.org] Interictal EEG displays diffuse and asynchronous high voltage spikes and slow waves suggesting the hypsarrhythmic pattern. B.[bmcneurol.biomedcentral.com] The spikes usually alternate randomly between focal, multifocal, and generalized discharges at different moments within a brief record.[web.archive.org]

  • Hydrocephalus

    Hydrocephalus is a clinical condition characterized by disturbance of cerebrospinal fluid regulation in the central nervous system. Cerebrospinal fluid regulation has three important steps - formation, flow and absorption. Infants with hydrocephalus presents with complaints such as poor feeding, vomiting, reduced[…][symptoma.com]

  • Benign Adult Familial Myoclonic Epilepsy

    Massa et al. identified the following EEG characteristics as predictive of a "complicated" course: intermittent slow wave focus, multiple, asynchronous spike wave foci, spike[euroformhealthcare.biz] […] wave clusters, generalized 3-Hz spike wave discharges, discharges with positive or negative myoclonia, or abundance of interictal abnormalities during waking or sleep.[euroformhealthcare.biz]

  • Dravet Syndrome

    When present, they consist of spikes, single and multiple spike-waves, generalized, symmetric or asymmetric, isolated or in brief bursts, and of localized sharp waves, slow[icnapedia.org] The localized findings are usually seated in the central areas, bilaterally, synchronous or asynchronous, and in the vertex, and may spread to the entire hemisphere but can[icnapedia.org]

  • Seizure

    "Seizures beget seizures" is a generally accepted clinical axiom. The argument follows that earlier treatment is more effective than later treatment in halting status epilepticus (SE). [20, 21] In caring for the seizure patient in the emergency department (ED), 3 basic pitfalls must be avoided. The first is failure to[…][emedicine.com]

  • Continuous Spike-and-Slow-Waves during Sleep

    Massa et al. identified the following EEG characteristics as predictive of a "complicated" course: intermittent slow wave focus, multiple, asynchronous spike wave foci, spike[euroformhealthcare.biz] […] wave clusters, generalized 3-Hz spike wave discharges, discharges with positive or negative myoclonia, or abundance of interictal abnormalities during waking or sleep.[euroformhealthcare.biz]
