| masked epilepsy | A form of epilepsy characterised by a paroxysmal disturbance, such as headache or vomiting, associated with an epileptic electroencephalographic pattern. (05 Mar 2000) |
|---|---|
| parietal lobe epilepsy | A localization-related epilepsy where seizures originate within the parietal lobe. Seizure semiology may involve abnormalities of sensation. (05 Mar 2000) |
| matutinal epilepsy | A form of epilepsy which occurs on awakening. (05 Mar 2000) |
| reflex epilepsy | Seizures which are induced by peripheral stimulation; e.g., audiogenic, laryngeal, photogenic, or other stimulation. Synonym: sensory precipitated epilepsy. (05 Mar 2000) |
| partial epilepsy | Epilepsy of various aetiologies characterised by focal seizures or secondarily generalised tonic-clonic seizures. Ictal symptoms are often related to the brain region where the seizure begins focally. Synonym: cortical epilepsy, local epilepsy, partial epilepsy. (05 Mar 2000) |
| visceral epilepsy | Epilepsy, usually psychomotor, in which the attacks are initiated by visceral symptoms or sensations; most cases have their focus in the temporal lobe. (05 Mar 2000) |
| pattern sensitive epilepsy | A form of reflex epilepsy precipitated by viewing certain patterns. (05 Mar 2000) |
| centrencephalic epilepsy | An imprecise term referring to epilepsy characterised electroencephalographically by bilateral synchronous discharges, and clinically by absence or generalised tonic-clonic seizures. (05 Mar 2000) |
| grand mal epilepsy | Older term for epilepsy characterised by generalised tonic-clonic seizure. (05 Mar 2000) |
| childhood absence epilepsy | A generalised epilepsy syndrome characterised by the onset of absence seizures in childhood, typically at age six or seven years. There is a strong genetic predisposition and girls are affected more often than boys. EEG reveals generalised 3 Hz spike-wave activity on a normal background. Prognosis for remission is good if the patient does not also have generalised tonic-clonic seizures. See: absence. Synonym: petit mal epilepsy, pyknolepsy. (05 Mar 2000) |
| childhood epilepsy with occipital paroxysms | A benign epilepsy syndrome characterised by frequent occipital spikes often activated by eye closure. It has a seizure semiology that includes visual manifestations; not always remitting later in life. (05 Mar 2000) |
| petit mal epilepsy | A generalised epilepsy syndrome characterised by the onset of absence seizures in childhood, typically at age six or seven years. There is a strong genetic predisposition and girls are affected more often than boys. EEG reveals generalised 3 Hz spike-wave activity on a normal background. Prognosis for remission is good if the patient does not also have generalised tonic-clonic seizures. See: absence. Synonym: petit mal epilepsy, pyknolepsy. (05 Mar 2000) |
| rolandic epilepsy | A benign, autosomal, dominant form of epilepsy occurring in children, characterised clinically by arrest of speech, by muscular contractions of the side of the face and arm and epileptic discharges electroencephalographically. Origin: Luigi Rolando (05 Mar 2000) |
| pharmacoresistent epilepsy | Epilepsy not adequately controlled by medication. Synonym: pharmacoresistent epilepsy. (05 Mar 2000) |
| photogenic epilepsy | A form of reflex epilepsy precipitated by light. (05 Mar 2000) |
