230 Possible Causes for Myoclonic Jerking, Progressive Loss of Vision

  • Neuronal Ceroid Lipofuscinosis

    jerk and visual impairment.[] Most childhood forms of NCL are clinically characterized by progressive loss of vision as well as mental and motor deterioration, epileptic seizures, and premature death,[] Myoclonic jerks constituted the most prominent paroxysmal phenomenon.[]

  • Neuronal Ceroid Lipofuscinosis 3

    Also typical are short, sharp muscle contractions called myoclonic jerks.[] Like the other neuronal ceroid-lipofuscinoses, it is characterized by progressive loss of vision, seizures, and loss of cognitive and motor functions, leading to premature[] Other features of the condition include recurrent seizures that involve uncontrollable muscle jerks (myoclonic epilepsy), difficulty coordinating movements (ataxia), vision[]

  • Myoclonic-Astatic Epilepsy

    The involvement of these structures might predispose to the typical seizure semiology of myoclonic jerks observed in MAE.[] Patients with NCLFs experience progressive loss of vision, and VS may decrease during the progression of the disease.[] jerks, by using burst-locked EEG averaging where necessary.[]

  • Neuronal Ceroid Lipofuscinosis 5

    By 4-5 years the children usually have myoclonic jerks of their limbs and head nods.[] […] degeneration of movement 0002333 Myoclonus 0001336 Progressive visual loss Progressive loss of vision Progressive vision loss Progressive visual impairment Slowly progressive[] […] muscles (myoclonic jerks), and seizures.[]

  • Dementia

    Occasionally, blurred vision and hallucinations are associated with the condition.[] Unlike dementia caused by Alzheimer’s, memory problems and behavioral changes caused by CJD progress rapidly, usually over a period of several months.[] Symptoms include memory loss, speech impairment, confusion, muscle stiffness and twitching and general lack of coordination, making the individual susceptible to falls.[]

  • Benign Adult Familial Myoclonic Epilepsy

    By the jerk-locked averaging method, a positive spike time-locked to the myoclonic jerk was demonstrated in four patients before 15-20 msec of myoclonic jerk.[] Patients with NCLFs experience progressive loss of vision, and VS may decrease during the progression of the disease.[] ., adj myoclon ic. A single myoclonic arm or leg jerk is normal when the person is falling asleep. Myoclonic jerks are severe with grand mal seizures.[]

  • Choroid Plexus Papilloma

    Six months later, he came to us with progressive loss of vision due to raised intracranial pressure.[] History of severe episodic headache, diplopia and progressive diminution of vision for one and a half months was also reported.[] Case 2 : A 32 year old female was admitted in December 1995 with history of progressive hearing loss in the right ear for 7 months.[]

  • Mucolipidosis

    Random multifocal myoclonic jerks had diffuse EEG correlates [Figure 1]. Attenuation of visual evoked potentials was noted.[] vision loss.[] Type I sialadosis is the milder form with onset of gait abnormalities, progressive vision loss, bilateral macular cherry-red spots, and myoclonus in the second or third decade[]

  • Familial Infantile Myoclonic Epilepsy

    One fifth of patients have photosensitivity, with myoclonic jerks precipitated by photic stimulation.[] This presents with onset of generalised tonic-clonic seizures between the ages of 5-10 years accompanied with progressive loss of cognitive skills, and loss of fine notor[] Sometimes, similar myoclonic jerks can occur also after an infectious event, and for these cases the more appropriate term of “parainfectious myoclonic jerks” has been introduced[]

  • Subacute Sclerosing Panencephalitis

    Typical initial symptoms consist of intellectual decline, deterioration in school performance, and myoclonic jerks.[] The authors here report a case of a 3-year-old child who presented with vision loss followed 15 months later by quadriparesis with bladder involvement.[] Features like myoclonic jerks, cognitive decline and typical EEG findings lead to a strong suspicion of SSPE.[]
