9 Possible Causes for Paroxysmal Activity - Sharp-Waves Bilaterally

  • Epilepsy

    OBJECTIVE: To study seizure control and rates of foetal malformation in pregnancies of women with epilepsy treated with antiepileptic drug polytherapy. METHODS: The use of conventional statistical methods to analyse the Australian Pregnancy Register records of 1810 pregnancies in women with epilepsy, 508 treated[…][ncbi.nlm.nih.gov]

  • 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]

  • Rolandic Epilepsy

    Rolandic epilepsy, sometimes also referred to as benign childhood epilepsy with centrotemporal spikes, is the most common type of childhood epilepsy. Spontaneous remission before puberty is observed in the majority of cases. Characteristic RE seizures are hemifacial motor seizures, sometimes also motorsensory[…][symptoma.com]

  • 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

    The evolution of severe periventricular leukomalacia was followed by ultrasonography in three newborn infants, and the subsequent myelination of the brain was assessed by nuclear magnetic resonance imaging. Four stages of periventricular leukomalacia could be identified by ultrasonography; (1) initial congestion,[…][ncbi.nlm.nih.gov]

  • Fragile X Syndrome

    Fragile X syndrome is the most common inherited form of cognitive deficiency in humans and perhaps the best-understood single cause of autism. A trinucleotide repeat expansion, inactivating the X-linked FMR1 gene, leads to the absence of the fragile X mental retardation protein. FMRP is a selective RNA-binding[…][ncbi.nlm.nih.gov]

  • Benign Familial Infantile Epilepsy

    The EEG examination showed diffuse abnormal background activity, with sporadic isolated bilateral sharp waves over the occipital regions (a).[onlinelibrary.wiley.com] […] and sporadic isolated bilateral sharp waves over the occipital regions (Fig. 4a).[onlinelibrary.wiley.com] In this patient, IPS induced moderate‐voltage irregular spike‐and‐slow wave complexes and paroxysmal bursts of high‐voltage polyspikes more evident over the occipital region[onlinelibrary.wiley.com]

  • Pyridoxine Dependency Syndrome

    The most noteworthy interictal pattern consists of bursts or runs of high voltage relatively bilaterally synchronous 1-4 Hz activity with intermixed spikes and or sharp waves[indianpediatrics.net] The other pre-pyridoxine paroxysmal EEG abnormalities include focal spikes or sharp waves, multi-focal spikes and single sharp waves recorded over a whole quadrant or over[indianpediatrics.net]
