1,558 Possible Causes for Lower and Upper Limbs Affected, Myoclonic Jerking, Photoparoxysmal Response

  • Benign Adult Familial Myoclonic Epilepsy

    Photoparoxysmal responses (PPR) were noted in 18 (95%) patients with BAFME but 1 (10%) with EGTCS.[ncbi.nlm.nih.gov] 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.[ci.nii.ac.jp] Attacks may last several minutes to half an hour and more frequently affect the lower than upper limbs.[epilepsydiagnosis.org]

  • Juvenile Myoclonic Epilepsy

    responses (PPRs).[ncbi.nlm.nih.gov] The myoclonic jerks occur rarely in EMA. They are usually mild and are freqently restricted to the upper extremities.[ncbi.nlm.nih.gov] PURPOSE: Juvenile myoclonic epilepsy (JME) is commonly associated with photoparoxysmal response (PPR) with a reported prevalence of 25-42%.[ncbi.nlm.nih.gov]

  • Idiopathic Generalized Epilepsy

    Other characteristic EEG features include polyspikes, polyspike-wave discharges, occipital intermittent rhythmic delta activity, and photoparoxysmal response.[ncbi.nlm.nih.gov] Myoclonic-astatic seizures consist of symmetric myoclonic jerks followed by periods of absent muscle tone that can result in falls.[symptoma.com] PURPOSE: Photosensitivity or photoparoxysmal response (PPR) is an electroencephalography trait that is highly associated with idiopathic generalized epilepsies (IGEs) and[ncbi.nlm.nih.gov]

  • Nocturnal Myoclonus Syndrome

    About a third of people with JME may show an abnormal EEG in response to flickering lights (called a photoparoxysmal response).[epilepsy.com] It has frequently been confused with, and should be clearly differentiated from, other normal jerking movements of sleep, such as partial myoclonic jerks and massive myoclonic[ncbi.nlm.nih.gov] Attacks may last several minutes to half an hour and more frequently affect the lower than upper limbs.[epilepsydiagnosis.org]

  • Familial Infantile Myoclonic Epilepsy

    response Increased epileptiform discharges in sleep state transitions Vaproate and levetiracetam good (lamotrigine can exacerbate myoclonus) – lifelong therapy Generalized[emilytam.com] One fifth of patients have photosensitivity, with myoclonic jerks precipitated by photic stimulation.[medlink.com] Targeted and whole-exome sequencing in a cohort of 580 patients with photosensitive epilepsy or photoparoxysmal response as determined by EEG revealed an overrepresentation[genomemedicine.biomedcentral.com]

  • Photosensitive Epilepsy

    A flashing strobe light, for example, can trigger a photoparoxysmal response in a predisposed individual.[mdedge.com] Seizure types in photosensitive epilepsy include focal onset occipital seizures, with initial visual symptoms, or generalized tonic seizures and myoclonic jerks seen in IGE[academic.oup.com] Generalized myoclonic jerks Generalized myoclonic jerks are usually symmetric and predominate in the upper limbs.[epilepsyontario.org]

  • Unverricht-Lundborg Syndrome

    Background activity kept stable during the course of the disease; generalized paroxysmal discharges and photoparoxysmal response gradually disappeared with a significant difference[moh-it.pure.elsevier.com] The myoclonic jerks occur in the muscles of the arms and legs closest to the torso, and are triggered due to a variety of common external stimuli.

  • Restless Legs Syndrome

    Complying with an irresistible urge to move the affected limbs brings temporary relief. Sleep may become disrupted, resulting in excessive daytime hypersomnolence.[icd9data.com] A disorder characterized by aching or burning sensations in the lower and rarely the upper extremities that occur prior to sleep or may awaken the patient from sleep.[icd10data.com] […] and rarely the upper extremities that occur prior to sleep or may awaken the patient from sleep.[icd9data.com]

  • Neuronal Ceroid Lipofuscinosis

    A characteristic photoparoxysmal response on electroencephalogram provided an important clue for the correct diagnosis of late infantile neuronal ceroid-lipofuscinosis, which[ncbi.nlm.nih.gov] jerk and visual impairment.[ncbi.nlm.nih.gov] EEGs revealed a photoparoxysmal response (PPR) on intermittent photic stimulation in 93% (13 of 14) of patients.[ncbi.nlm.nih.gov]

[Figure 1][neurologyindia.com] As the affected children grow up, they develop myoclonic jerking, and their seizures may become refractory to treatment. Synonym: severe myoclonic epilepsy of infancy[medical-dictionary.thefreedictionary.com] Generalized ictal myoclonic jerks: The generalized ictal myoclonic jerks are always preceded by clear-cut spike-wave discharges.[icnapedia.org]
