74 Possible Causes for EEG Multifocal Abnormality

  • 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]

  • Absence Seizure

    BACKGROUND: Absence seizures are a subtype of epileptic seizures clinically characterized by transient alterations in states of consciousness and by electroencephalography indicating diffuse spike-wave discharges (SWD). Conventional brain magnetic resonance imaging (MRI) is not routinely used to establish the[…][ncbi.nlm.nih.gov]

  • Juvenile Myoclonic Epilepsy

    Juvenile myoclonic epilepsy (JME) is characterized by seizures, severe cognitive abnormalities, and behavior impairments. These features could evolve over time and get worse, especially when the encephalopathy is pharmacoresistant. Thus, genetic studies should provide a better understanding of infantile epilepsy[…][ncbi.nlm.nih.gov]

  • Idiopathic Generalized Epilepsy

    The term idiopathic generalized epilepsy (IGE) is used to designate a group of epileptic conditions with a genetic etiology. Patients with IGE have otherwise normal development, don't present with any structural brain damage and usually have a family history of epilepsy. Clinical manifestations of IGE depend on its[…][symptoma.com]

  • Encephalopathy

    Encephalopathy (; from Ancient Greek: ἐνκέφαλος "brain" πάθος "suffering") means any disorder or disease of the brain, especially chronic degenerative conditions. In modern usage, encephalopathy does not refer to a single disease, but rather to a syndrome of overall brain dysfunction; this syndrome can have[…][en.wikipedia.org]

  • Juvenile Absence Epilepsy

    Valproic acid is commonly and effectively used in the treatment of idiopathic generalized epilepsies, including juvenile absence epilepsy. Although several adverse effects are associated with this drug, it has only rarely been known to exacerbate seizures. Similar to antiarrhythmic drugs aggravating particular[…][ncbi.nlm.nih.gov]

  • Paroxysmal Exertion-Induced Dyskinesia

    Background Paroxysmal exercise-induced dystonia is a rare hyperkinetic disease characterized by episodic dystonic attacks after prolonged exercise. However, its pathophysiological and anatomical basis are poorly understood. Objective To explore the exact anatomical location responsible for paroxysmal[…][archneur.ama-assn.org]

  • Puerperium

    In addition, the EEG shows abnormal patterns of brain activity.[doi.org] Stage 2 is marked by obtundation, hypotonia, strong distal flexion and multifocal seizures.[doi.org]

  • Birth

    In addition, the EEG shows abnormal patterns of brain activity.[doi.org] Stage 2 is marked by obtundation, hypotonia, strong distal flexion and multifocal seizures.[doi.org]

  • Panayiotopoulos Syndrome

    Interictal EEGs revealed functional multifocal abnormalities. The evolution was benign in all patients with seizures remission before the age of 14.[ncbi.nlm.nih.gov] EEG revealed an abnormal pattern with recurrent multifocal epileptiform activity over the bilateral occipital and frontal regions during sleep.[ncbi.nlm.nih.gov] There is marked variability of interictal EEG findings from normal to multifocal spikes that also change significantly in serial EEGs.[en.wikipedia.org]
