  • Idiopathic Generalized Epilepsy

    Generalized spike-wave discharges and diffuse paroxysmal fast activity were categorized as interictal and ictal, based on duration of less than 10 seconds or greater, respectively[]

  • 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[…][]

  • 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[…][]

  • 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[…][]
