Temporal Lobe Epilepsy

Temporal lobe epilepsy is a form of focal epilepsy, a chronic neurological condition characterized by recurrent seizures. Over 40 types of epilepsies are known. They fall into two main categories: partial-onset (focal or localization-related) epilepsies and generalized-onset epilepsies. Partial-onset epilepsies account for about 60% of all adult epilepsy cases, and temporal lobe epilepsy (TLE) is the most common single form causing refractory epilepsy.

Temporal lobe epilepsies are a group of medical disorders in which humans and animals experience recurrent epileptic seizures arising from one or both temporal lobes of the brain. Two main types are internationally recognized according to the International League Against Epilepsy.

  • Medial temporal lobe epilepsy :(MTLE) arises in the hippocampus, parahippocampal gyrus and amygdala which are located in the inner aspect of the temporal lobe.
  • Lateral temporal lobe epilepsy (LTLE) arises in the neocortex on the outer surface of the temporal lobe of the brain.

Because of strong interconnections, seizures beginning in either the medial or lateral temporal areas often spread to involve both areas and also to neighboring areas on the same side of the brain as well as the temporal lobe on the opposite side of the brain. Temporal lobe seizures can also spread to the adjacent frontal lobe and to the parietal and occipital lobes. The causes or etiology of different temporal lobe epilepsies vary and are discussed below.

Famous quotes containing the words epilepsy and/or temporal:

    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)

    When once a certain class of people has been placed by the temporal and spiritual authorities outside the ranks of those whose life has value, then nothing comes more naturally to men than murder.
    Simone Weil (1909–1943)
