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[neuroweb.us] Photoparoxysmal responses (PPR) were noted in 18 (95%) patients with BAFME but 1 (10%) with EGTCS.[ncbi.nlm.nih.gov] […] childhood epilepsy with centrotemporal spike -childhood epilepsy with occipital paroxysms Generalized epilepsies & synd.[enotes.tripod.com]

    responses (PPRs).[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] Photic stimulation disclosed a marked photoparoxysmal response, sometimes associated with myoclonic jerks.[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] PURPOSE: Photosensitivity or photoparoxysmal response (PPR) is an electroencephalography trait that is highly associated with idiopathic generalized epilepsies (IGEs) and[ncbi.nlm.nih.gov] METHODS: We studied 15 photosensitive IGE patients showing a photoparoxysmal response (PPR) to IPS at 20Hz.[ncbi.nlm.nih.gov]

  • Juvenile Absence Epilepsy

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