8,286 Possible Causes for Focal Dystonia - Upper Limb, Photoparoxysmal Response, Seizure

  • Benign Adult Familial Myoclonic Epilepsy

    The most common signs and symptoms in descending order are: asymmetric limb rigidity (100%), upper limb apraxia (91%), gait difficulties (89%), stimulation-sensitive focal[] Photoparoxysmal responses (PPR) were noted in 18 (95%) patients with BAFME but 1 (10%) with EGTCS.[] Focal seizures can spread and become bilateral tonic-clonic seizures. Generalized Seizures With generalized seizures, most or all of the brain is involved.[]

  • Juvenile Myoclonic Epilepsy

    responses (PPRs).[] Response to valproate therapy of rotatory seizures was good.[] PURPOSE: Juvenile myoclonic epilepsy (JME) is commonly associated with photoparoxysmal response (PPR) with a reported prevalence of 25-42%.[]

  • Photosensitive Epilepsy

    A flashing strobe light, for example, can trigger a photoparoxysmal response in a predisposed individual.[] A seizure that is brought on by a visual trigger is described as a visual reflex seizure, a photo convulsive seizure, or a photosensitive seizure.[] The second patient's photoparoxysmal response was suppressed by both parallel-polarized and blue cross-polarized glasses, whereas the third patient's photoparoxysmal response[]

  • Idiopathic Generalized Epilepsy

    Other characteristic EEG features include polyspikes, polyspike-wave discharges, occipital intermittent rhythmic delta activity, and photoparoxysmal response.[] Unilateral seizures, or hemiconvulsive attacks, are motor seizures with tonic and/or clonic phenomena that involve only one side of the body.[] PURPOSE: Photosensitivity or photoparoxysmal response (PPR) is an electroencephalography trait that is highly associated with idiopathic generalized epilepsies (IGEs) and[]

  • Progressive Myoclonic Epilepsy Type 8

    With doses of up to 10 g/day, elimination of photoparoxysmal responses was achieved in all 3 patients.[] These seizures can be mistaken for tics, tremors or clumsiness. How are myoclonic seizures diagnosed? The seizures themselves are easy to identify.[] response Negative 6 and 20 Hz provoked a photoparoxysmal response Negative Brain MRI Mild atrophy of the cerebellum and brainstem Not available Not available Not available[]

  • Temporal Lobe Epilepsy

    Contralateral upper limb dystonia may develop and head and eye version to the contralateral side can occur.[] Berardelli, The Photoparoxysmal Response Reflects Abnormal Early Visuomotor Integration in the Human Motor Cortex, Brain Stimulation, 8, 6, (1151), (2015). Nash N.[] […] generalized seizures.[]

  • 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[] These seizures can be mistaken for tics, tremors or clumsiness. How are myoclonic seizures diagnosed? The seizures themselves are easy to identify.[] GLOSSARY ANOVA analysis of variance ; KM Kaplan-Meier ; PHT phenytoin ; PME progressive myoclonus epilepsy ; PPR photoparoxysmal responses ; PSW polyspikes and waves ; SSEP[]

  • Progressive Myoclonic Epilepsy Type 7

    Intermittent light stimulation generated a photoparoxysmal response at low frequencies. Epileptic activity did not increase during stages of drowsiness.[] .  The syndrome of PME consists of myoclonic seizures, tonic–clonic seizures, and progressive neurologic dysfunction, particularly ataxia and dementia.  Onset - Any age[] PER was quite effective in suppressing photoparoxysmal response in these patients.[]

  • Late-Infantile Neuronal Ceroid Lipofuscinosis

    […] with a photoparoxysmal response associated with other epilepsy syndromes.[] Symptoms appear between ages 2 and 4 and consist of typical neurodegenerative complications: loss of muscle function (ataxia), drug resistant seizures (epilepsy), apraxia,[] Curvilinear bodies were also present in the lymphocytes of a neurologically normal younger female sibling of patient 1, who has had a single seizure, leading to speculation[]

  • Focal Epilepsy - Speech Disorder - Mental Retardation

    Photoparoxysmal responses (PPRs) are generalized epileptiform abnormalities occurring during photic stimulation.[] Many patients, but not all, have seizures. Seizure activity typically resolves by teenage years, but speech is permanently lost.[] This is known as subclinical seizure activity.[]
