251 Possible Causes for Slow-Frequency High-Amplitude Waves with High-Frequency Polyspikes, Spike-and-Slow-Wave or Polyspike-and-Slow-Wave Discharges, Variable Psychomotor Retardation

  • Myoclonic-Astatic Epilepsy

    retardation mainly affecting speech.[ipfs.io] Myoclonic-atonic seizures with falls are the defining symptoms. • EEG shows frequent generalized discharges of spike/polyspike-slow wave at varying frequencies of 2.5 to 3[medlink.com] Boys (74%) are more often affected than girls (Doose and Baier 1987a). [2] Prognosis Epilepsy with myoclonic-astatic seizures has a variable course and outcome.[ipfs.io]

  • Generalized Clonic or Tonic-Clonic Seizures

    ‘Contrary to popular folk belief, nothing should be placed in the mouth during the seizure. Severe injury could occur.’ Generalized tonic clonic seizures (grand mal seizures) are the most common and best known type of generalized seizure. They begin with stiffening of the limbs (the tonic phase), followed by jerking[…][epilepsynw.org]

  • Benign Adult Familial Myoclonic Epilepsy

    Abstract Benign adult familial myoclonic epilepsy (BAFME) has been mapped to chromosome 8q23.3-q24.1, 2p11.1-q12.1, 5p15.31-p15.1, and 3q26.32-3q28, in Japanese, Italian, Thai, and French pedigrees, respectively. Recently, we investigated a Chinese BAFME family. Clinical and electrophysiological studies revealed that nine[…][ncbi.nlm.nih.gov]

  • Juvenile Myoclonic Epilepsy

    Juvenile myoclonic epilepsy is a common form of epilepsy mainly characterized by myoclonic jerks, but affected individuals may also experience generalized tonic-clonic seizures and absence seizures. Symptom onset typically occurs around puberty and although the disease persists into adulthood, patients do respond[…][symptoma.com]

  • Idiopathic Generalized Epilepsy

    Tonic status epilepticus (TSE) in patients with idiopathic generalized epilepsy (IGE) is not well recognized. The objective of this study is to report episodes of TSE in patients with IGE. We retrospectively reviewed the clinical and EEG evaluation of three IGE patients who presented TSE. The three patients had mainly[…][ncbi.nlm.nih.gov]

  • Myoclonic Jerking

    Massage therapists may be the first to witness their clients’ myoclonic symptoms. Bodyworkers able to differentiate between muscle spasms, harmless twitches and pathological body jerks will know when to refer their clients for a neurological evaluation. When a client’s body jerks on the massage table, it is natural[…][integrativehealthcare.org]
