199 Possible Causes for Focal Dystonia - Upper Limb, Parietal Focal Spikes, Photoparoxysmal Response

  • 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.[] […] childhood epilepsy with centrotemporal spike -childhood epilepsy with occipital paroxysms Generalized epilepsies & synd.[]

  • Juvenile Myoclonic Epilepsy

    responses (PPRs).[] PURPOSE: Juvenile myoclonic epilepsy (JME) is commonly associated with photoparoxysmal response (PPR) with a reported prevalence of 25-42%.[] Photic stimulation disclosed a marked photoparoxysmal response, sometimes associated with myoclonic jerks.[]

  • Idiopathic Generalized Epilepsy

    Other characteristic EEG features include polyspikes, polyspike-wave discharges, occipital intermittent rhythmic delta activity, and photoparoxysmal response.[] PURPOSE: Photosensitivity or photoparoxysmal response (PPR) is an electroencephalography trait that is highly associated with idiopathic generalized epilepsies (IGEs) and[] METHODS: We studied 15 photosensitive IGE patients showing a photoparoxysmal response (PPR) to IPS at 20Hz.[]

  • Juvenile Absence Epilepsy

    The EEG showed a photoparoxysmal response in over a quarter of the patients, and one in five displayed asymmetrical anomalies.[] About a third of people with JME may show an abnormal EEG in response to flickering lights (called a photoparoxysmal response).[] Intermittent photic stimulation induces an occipital photoparoxysmal response and may induce generalized discharges with a wide range of flash frequencies (5–40 Hz) ( Guerrini[]

  • West Syndrome

    IARS2 encodes isoleucine-tRNA synthetase, which is aclass-1 amino acyl-tRNA synthetase. IARS2 mutations are reported to cause Leigh syndrome or cataracts, growth hormone deficiency, sensory neuropathy, sensorineural hearing loss, and skeletal dysphasia syndrome (CAGSSS). To our knowledge, IARS2 mutations and[…][]
