13. Precortical dysfunction of spatial and temporal visual processing in migraine.
This paper examines spatial and temporal processing in migraineurs (diagnosed according to International Headache Society criteria, 1988), using psychophysical tests that measure spatial and temporal responses. These tests are considered to specifically assess precortical mechanisms. Results suggest precortical dysfunction for processing of spatial and tempo

14. The temporal sequence of aura-sensations in patients with complex focal seizures with particular attention to ictal aphasia.
The sequences of aura sensations in 143 patients with complex partial seizures, were analysed with special emphasis on aphasic symptoms. Anxiety, epigastric sensation and visual hallucination were experienced early in the course of the aura, while illusion of familiarity and aphasia occurred late in the course of the aura. Three groups of interconnections of

A 49 year old woman reported an attack of transient neurological dysfunction associated with unilateral headache. A prominent feature of the aura was a period of complete achromatopsia, so that the visual scene was experienced in monochrome. The episode developed to include features of prosopagnosia and spatial agnosia before resolving completely. Other epis

16. Migraine aura without headache: transient ischaemic attack or not?
Patients with "migraine aura without headache" can be separated from those with transient ischaemic attacks (TIA) on the basis of the onset of symptoms, which is generally gradual and which spread or intensify over minutes or hours, and from the typical migrainous nature of their visual symptoms. Fifty cases were prospectively identified and these were compa

17. Migraine madness: recurrent psychosis after migraine.
A 69 year old man with longstanding migraine with aura had four episodes of psychosis lasting 7-28 days during a 17 year period. During attacks he had formed visual hallucination and delusions, including reduplicative paramnesia. His mother was similarly affected. His EEG showed symmetrical frontal delta waves. The time course and EEG changes are similar to

18. Migraine and non-migrainous headaches. A community survey in Jerusalem.
The epidemiology of migraine and non-migrainous headaches (NMH) was investigated in a community survey in a neighbourhood of western Jerusalem in 1969-71. Diagnoses were based on histories taken by physicians. Prevalence rates among persons aged 15 and over were 10.1% for migraine (including classical migraine, 2.1%) and 25.6% for frequent NMH (more than onc
