110 Possible Causes for Focal Sharp-Waves

  • Epilepsy

    (EEG) hallmark of focal-onset seizures is the focal interictal epileptiform spike or sharp wave.[emedicine.medscape.com] The cellular neurophysiologic correlate of an interictal focal epileptiform discharge in single cortical neurons is the paroxysmal depolarization shift (PDS).[emedicine.medscape.com] For a review, see the epilepsy book of Rho, Sankar, and Cavazos. [5] For a more recent review, see Kramer and Cash. [6] Pathophysiology of focal seizures The electroencephalographic[emedicine.medscape.com]

  • Rolandic Epilepsy

    sharp waves and RD in siblings.[ncbi.nlm.nih.gov] Focal sharp waves in the centrotemporal area define the electroencephalographic (EEG) trait for the syndrome, are a feature of several related childhood epilepsies and are[ncbi.nlm.nih.gov] We acknowledge Professor Hermann Doose's intellectual contribution to the nosology of focal sharp wave-associated phenotypes in children.[doi.org]

  • Vascular Dementia

    Vascular dementia (VaD) is a general term describing problems with reasoning, planning, judgment, memory, and other thought processes caused by brain damage from impaired blood flow to the brain. Cognitive rehabilitation and physical therapy are the mainstays of dementia treatment, although often ineffective[…][ncbi.nlm.nih.gov]

  • Encephalitis

    Encephalitis is inflammation of the brain. Severity is variable. Symptoms may include headache, fever, confusion, a stiff neck, and vomiting. Complications may include seizures, hallucinations, trouble speaking, memory problems, and problems with hearing.Causes of encephalitis include viruses such as herpes simplex virus[…][en.wikipedia.org]

  • Creutzfeldt Jakob Disease

    Prion diseases are unique transmissible neurodegenerative diseases that have diverse phenotypes and can be familial, sporadic, or acquired by infection. Recent findings indicate that the PrP genotype and the PrP(Sc) type have a major influence on the disease phenotype in both sporadic and familial human prion[…][ncbi.nlm.nih.gov]

  • Periventricular Leukomalacia

    2015 ICD-9-CM Diagnosis Code 779.7 Periventricular leukomalacia 2015 Billable Thru Sept 30/2015 Non-Billable On/After Oct 1/2015 ICD-9-CM 779.7 is a billable medical code that can be used to indicate a diagnosis on a reimbursement claim, however, 779.7 should only be used for claims with a date of service on or before[…][icd9data.com]

  • Fragile X Syndrome

    Fragile X syndrome is a genetic condition caused by a mutation of the fragile X mental retardation 1 (FMR1) gene on the X chromosome. Fragile X syndrome in males is usually more severe than in females and males are never asymptomatic. This is because males have only one X chromosome (unlike females that have 2[…][symptoma.com]

  • Panic Attacks

    Focal paroxysms of sharp wave activity appeared on both patients' EEGs coincident with the spontaneous onset of panic attack symptoms. Both patients remained conscious.[ncbi.nlm.nih.gov] The correlation of focal paroxysmal EEG changes with panic attack symptoms suggests that these attacks were produced by partial seizure activity.[ncbi.nlm.nih.gov]

  • Stroke

    Sharp or spike waves, TIRDA, FIRDA, focal slowing, diffuse slowing, and asymmetry had no significant difference between groups.[n.neurology.org]

  • Cardiogenic Syncope

    A standard EEG showed focal spike and wave with delta slowing on the right centrotemporal region (C4-T4).[jnnp.bmj.com] A Medilog 9000 ambulatory EEG-ECG recording captured a seizure (fig 2 ) beginning with right centrotemporal recruiting sharp waves, followed by a progressive sinus bradycardia[jnnp.bmj.com]
