3,625 Possible Causes for Epileptiform Activity, Hyperreninemia, Syncope

  • Traumatic Brain Injury

    Poorly controlled chronic medical problems can result in head trauma by causing confusion or syncope and can also contribute to ongoing symptoms.[doi.org] Ling, Spontaneous Epileptiform Activity in Rat Neocortex after Controlled Cortical Impact Injury, Journal of Neurotrauma, 27, 8, (1541), (2010).[dx.doi.org] Kombian, Anticonvulsant enaminone E139 suppresses epileptiform activity in rat hippocampal slices, Epilepsy Research, 76, 2-3, (85), (2007).

  • Temporal Lobe Epilepsy

    We report a case of a previously healthy man presenting with syncope in whom telemetry revealed sinus arrest.[ncbi.nlm.nih.gov] However, little is currently known about the modulation of these networks by epileptiform activity, such as interictal spikes and seizures.[ncbi.nlm.nih.gov] A 25-year-old previously healthy man was hospitalized for syncope. While standing, he suddenly lost consciousness, followed by a generalized tonic clonic seizure.[ncbi.nlm.nih.gov]

  • Epilepsy

    OR (syncope or non convulsive syncope or syncopal attack).mp.} LIMIT to (human and english language)].[doi.org] It remains unclear whether seizures and epileptiform activity on the EEG are causative or comorbid.[ncbi.nlm.nih.gov] Through an accurate Video-EEG polygraphic analysis, we demonstrated that seizures are related to an abnormal increase of epileptiform activity after eye-closure or loss of[ncbi.nlm.nih.gov]

  • Hyponatremia

    Patients with hyponatremia often present with changes in mental status or with syncope.[consultant360.com] In this setting, release of both antidiuretic hormone (ADH) (increases renal permeability to water) and renin (increases renal sodium retention) occurs.[doi.org] "Syncope: risk stratification and clinical decision making". Emergency Medicine Practice. 16 (4): 1–22, quiz 22–3. PMID 25105200.[en.wikipedia.org]

  • Panayiotopoulos Syndrome

    […] for neurocardiogenic syncope and the EEG shows focal spikes.[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] During non-rapid eye movement (NREM) sleep, the EEG showed epileptiform activity of continuous spike-wave greater than 85% ( Fig 2 ).[scielo.br]

Child.[medicinenet.com] A clinical trial using anti-epileptics could be successful in patients not responding to antidepressants or in the presence of epileptiform EEG activity.[ncbi.nlm.nih.gov] ., palpitations, dyspnea, syncope) Mitral valve prolapse Pulmonary embolus (e.g., dyspnea, hyperpnea, chest pain) Asthma (e.g., dyspnea, wheezing) Hyperthyroidism (e.g., palpitations[emedicine.medscape.com]

  • Vasovagal Syncope

    Cardiac vasovagal syncope has the highest number of mortality while non-cardiac syncope doesn’t have such high mortality.[symptoma.com] activity, implying feigned syncope (pseudosyncope) with pseudoseizures.[ncbi.nlm.nih.gov] A combination of factors may cause a brief syncopal episode in the ICU.[ncbi.nlm.nih.gov]

  • Focal Onset Impaired Awareness Seizure

    This is the first report of a partial epileptic seizure precipitated by vasovagal syncope and the first example of an epileptic seizure induced by syncope in an adult.[ncbi.nlm.nih.gov] EEG technologists may use activation procedures such as hyperventilation and photic stimulation to enhance the ability of EEG to detect epileptiform activity.[currentpsychiatry.com] Electrocardiographic Holter monitoring disclosed only sinus bradycardia so he underwent head up tilt testing to exclude vasovagal syncope.[jnnp.bmj.com]

  • Stroke

    The largest proportions of chameleons were AMS, syncope, hypertensive emergency, systemic infection, and suspected ACS.[ncbi.nlm.nih.gov] The first EEG background activity asymmetry and first EEG with interictal epileptiform activity were independent predictors of poststroke epilepsy during the first year after[onlinelibrary.wiley.com] Key words: abnormal EEG, non-epileptiform abnormalities, slow activity.[scielo.br]

  • Limbic Encephalitis

    In the latest Case Record of the Massachusetts General Hospital , a 75-year-old man was seen because of memory loss and episodes of near-syncope, with word-finding difficulty[blogs.nejm.org] Electroencephalography showed focal or generalized slowing and/or epileptiform activity, maximal in the temporal regions, in all 22 patients tested.[ncbi.nlm.nih.gov] During the prodrome of FBDS alone, patients had normal sodium and brain MRIs, but electroencephalography demonstrated ictal epileptiform activity in 7 patients (24%).[ndcn.ox.ac.uk]
