5,131 Possible Causes for 3-4 Hz Spikes, Disharmonic Maturation of Phalanges and Carpal Bones, Mental Retardation

  • Myoclonic-Astatic Epilepsy

    In contrast, LGS was associated with mental retardation, which persisted after seizure control.[ncbi.nlm.nih.gov] […] presence of generalized spike- or polyspike-wave EEG discharges at 2-3 Hz, without focal spike discharges; and (4) exclusion of severe and benign myoclonic epilepsy (SME,[ncbi.nlm.nih.gov] EEG shows regular and irregular bilaterally synchronous 2- to 3-Hz spike-waves and polyspike patterns with a 4- to 7-Hz background. 84% of affected children show normal development[ipfs.io]

  • West Syndrome

    We report a girl with mild mental retardation with onset of infantile spasms at age of 9 months.[ncbi.nlm.nih.gov] Since then, mental retardation, particularly in terms of language development, became increasingly more obvious.[ncbi.nlm.nih.gov] A 6-month-old girl visited our hospital because of mental retardation, regression, and tonic spasms in cluster.[ncbi.nlm.nih.gov]

    Epilepsy with mental retardation limited to females (EFMR) is a rare type of X-linked epilepsy disorder, affecting heterozygous females disproportionately.[ncbi.nlm.nih.gov] […] to 8 years of age, in an otherwise apparently healthy child. 3 The classic electroencephalogram (EEG) shows generalized spike-wave bursts (of 3 Hz) with normal background[doi.org] Berkovic, Epilepsy and mental retardation limited to females: an under-recognized disorder, Brain, Volume 131, Issue 4, April 2008, Pages 918–927, Download citation file:[brain.oxfordjournals.org]

    MENTAL RETARDATION, X-LINKED, SYNDROMIC, HEDERA TYPE; MRXSH Is also known as mental retardation, x-linked, with epilepsy;mrxe;mrxsh Related symptoms: Intellectual disability[mendelian.co] The EEG shows generalised spike and wave discharges of 3 to 4 Hz and some with photic sensitivity. This is potentially a lifelong epilepsy.[pennsw.com.au] retardation becomes clearer gradually. (6) The EEGs initially lack epileptic discharges, and later they will show generalized spike-and-wave, or generalized polyspike-and-wave[jstage.jst.go.jp]
