Childhood absence epilepsy (CAE), also known as pyknolepsy, is an idiopathic generalized epilepsy which occurs in otherwise normal children. The age of onset is between 4–10 years with peak age between 5–7 years. Children have absence seizures which although brief (~4–20 seconds), they occur frequently, sometimes in the hundreds per day. The absence seizures of CAE involve abrupt and severe impairment of consciousness. Mild automatisms are frequent, but major motor involvement early in the course excludes this diagnosis. The EEG demonstrates characteristic "typical 3Hz spike-wave" discharges. Prognosis is excellent in well-defined cases of CAE with most patients "growing out" of their epilepsy.

Famous quotes containing the words childhood, absence and/or epilepsy:
“Children became an obsessive theme in Victorian culture at the same time that they were being exploited as never before. As the horrors of life multiplied for some children, the image of childhood was increasingly exalted. Children became the last symbols of purity in a world which was seen as increasingly ugly.”
—C. John Sommerville (20th century)
“... in no part of the world is genteel visiting founded on esteem, in the absence of suitable furniture and complete dinner-service.”
—George Eliot [Mary Ann (or Marian)
“We are compelled by the theory of God’s already achieved perfection to make Him a devil as well as a god, because of the existence of evil. The god of love, if omnipotent and omniscient, must be the god of cancer and epilepsy as well.... Whoever admits that anything living is evil must either believe that God is malignantly capable of creating evil, or else believe that God has made many mistakes in His attempts to make a perfect being.”
—George Bernard Shaw (1856–1950)
