Measurements of the ventricular brain ratio (VBR), width of the sylvian fissure, and symmetry of the frontal lobes were obtained from 26 chronic schizophrenic patients, 22 alcoholic and neurological patients, and 20 normal controls. All schizophrenic subjects were non-responsive to long-term neuroleptic medication for 3-25 yr and were between 23 and 45 yr of age. Detailed diagnostic workups differentiated two sub-groups by DSM III criteria, residual and paranoid. The former group was characterized by large VBRs while the paranoids were within the range of normal controls. Those patients with VBRs greater than nine had wider sylvian fissures and increased frequency of reversed frontal asymmetry. As a group, the VBRs of all schizophrenics differed significantly from normal controls but did not differ from those of alcoholics or patients with neurological disorders (migraine, generalized seizures). This finding indicates that DSM III criteria applied to CT scan measures may help define a sub-group within the schizophrenias. While not specific to this disorder, the underlying pathology demonstrating increased VBRs and other CT scan changes may be specific to but different from other disorders.

We studied a 14-year-old boy with episodes of elementary visual hallucinations, blindness, and headache. Electroencephalogram (EEG) showed continuous spike and slow-wave activity, which was confined to the posterior regions; this was related to eyes closed or darkness, but it was inhibited when the patient opened his eyes in an illuminated room or during retained central vision in darkness. The clinical and EEG manifestations were easily controlled by antiepileptic drugs. This case resembles four cases of a recently reported benign syndrome of "basilar migraine, seizures, and severe epileptiform EEG abnormalities. Whether the syndrome is migrainous or epileptic has yet to be elucidated.

Vestibular function studies were performed in 20 children with symptoms suggesting basilar artery migraine. Sixteen children had abnormalities on bithermal caloric testing. Labyrinthine preponderance was found in 1 child with labyrinthine concussion and in 6 children with symptoms suggesting ischemia of the territory supplied by the basilar artery and the occipital branches of the posterior cerebral arteries. Directional preponderance was found in 4 children with symptoms suggesting ischemia of the posterior temporal branches of the posterior cerebral arteries. Five children had both labyrinthine and directional preponderance. normal electronystagmographic findings were present in 4 children and correlated clinically with a milder illness. Head trauma was the triggering factor for the migraine in 5 children. Five children developed complex partial seizures and had evidence of directional preponderance (2 children) and combined labyrinthine and directional preponderance (2 children). The presence of abnormalities on electronystagmography in children with basilar artery migraine correlates with the severity of the disease. Directional preponderance or labyrinthine and directional preponderance are more frequently correlated with ischemia in the posterior temporal branches of the posterior cerebral arteries and may suggest a higher risk of developing vertiginous seizures when ischemia is prolonged.

Two cases are reported of patients whose EEGs showed localised rhythmic seizure activity in the midtemporal regions of one or both hemispheres, unaccompanied by any clinical symptoms: the patients' histories differed: one was of classic migraine and the other complex partial epilepsy. The frequency and morphology of the paroxysmal anomalies was identical in the waking state and in sleep. The nosographic classification of the phenomenon is discussed with reference to Gibbs' reports regarding the "psychomotor variant type of seizure discharge", to the work of Lipman and Hughes on "rhythmic mid-temporal discharge" and to that of Westmoreland and Klass on the "subclinical rhythmic EEG discharge of adults". But in contrast to the last phenomenon there were no signs pointing to a diffuse cerebrovascular disease. Reports of such a pattern are rare in the European literature and nonexistent in the Italian literature, facts which make an ordinary interpretation of the phenomenon difficult.

Occasionally patients in the stroke age-bracket over 40 have unexplained transient cerebral ischemic attacks in association with normal cerebral angiograms. From this group 120 have been collected in whom the transient episodes resembled the neurological accompaniments of migraine. According to symptoms, the patients were categorized as follows: Visual accompaniments (patients with only ordinary scintillating scotoma were excluded), 25; visual and paresthesias, 18; visual and speech disturbance, 7; visual, and brain stem symptoms, 14; visual, paresthesias, and speech disturbance, 7; visual, paresthesias, speech disturbance and paresis, 25; recurrence of old stroke deficit, 9; miscellaneous, 8. In establishing the diagnosis angiography is advisable in all but classical cases. Typical of migrainous accompaniments are the buildup and migration of visual scintillations, the march of paresthesiae, and progression from one accompaniment to another, characteristics that do not occur in thrombosis and embolism. Diagnosis facilitated when 2 or more similar episodes have occurred or migraine-like scintillations are present. Headache occurred in 50% of cases. Other cerebrovascular processes, coagulation disorders, and cerebral seizures must be ruled out.

Five cases of alternating hemiplegia in infancy are reported. Special consideration is given to the associated ictal manifestations (tonic seizures, dystonic posturing and abnormal movements bouts of nystagmus and acute autonomic disturbances), some of which were noted in every case. Previously reported cases are reviewed critically, 14 of whom are considered to belong to the same syndrome as the five presented here. The nosology of the syndrome is discussed, and the differences between alternating hemiplegia and the common types of hemiplegia or basilar migraine are emphasized. Whatever its exact nature, alternating hemiplegia in infancy constitutes a well-defined and recognizable syndrome, with a guarded mental and neurological prognosis.

The cranial computerized axial tomography (CAT) findings in groups of patients with epilepsy, migraine, hypertension, and other general medical disorders have been reviewed to assess the frequency and patterns of focal and diffuse brain damage. In addition to demonstrating focal lesions in a proportion of patients with seizures and in patients presenting with a stroke, the CAT scan showed a premature degree of cerebral atrophy in an appreciable proportion of patients with long-standing epilepsy, hypertension and diabetes, and in some patients with migraine, valvular and ischaemic, heart disease, chronic obstructive airways disease, and chronic renal failure. The value of CAT as a means of screening for brain damage in groups of individuals at risk is discussed.

The conversion of Saul to Paul was a major event in the history of Western culture. Compared with its impact, any medical comments may seem redundant, but they have kept their place in the literature for many centuries. The flashing light that caused Saul to fall is often explained as solar retinopathy or keratitis, a seizure, or even a hysterical fit. These interpretations propose either a trivial injury or disease that would interfere with mental health. Neither version is quite compatible with the dramatic dimension of the event and with Paul's later achievements and sufferings. In later years, Paul became a great manager, preacher and writer who was able to carry on under any kind of duress, though not without very painful reactions. He was suffering from bouts of unilateral headache, and also from a chronic eye condition which gave great trouble to his followers but did not cause lasting damage; the descriptions fulfil the criteria for migraine without aura of the 1988 Headache Classification. If the flashing light that caused Paul to fall down is interpreted as a visual migraine aura, with the additional symptoms of "not seeing" or photophobia and anorexia, it falls into place with his later history of migraine.

A cohort of 8 patients with myxoma of the left atria and neurological manifestations is reported. Cerebral ischaemia, sometimes responsible for epileptic seizures, led to the discover of the myxoma (5 cases) or recurrence after exeresis (1 case) with imaging evidence of cerebral infarction in 5 cases. The first manifestation was a retinal embolism and temporary ischaemia in 1 case and pulmonary embolism with regressive cerebral ischaemia in another case with bilateral myxoma. Some clinical particularities should be underlined including exercise-induced neurological defect (3 cases), systemic embolism associated with cerebral infarction (3 cases), migraine headache as the initial manifestation (1 case) preceding by a pseudolupic syndrome suggesting the possibility of cerebral vasculitis or infectious endocarditis (1 case). The prognosis depends on the risk of recurrent atrial tumour formation (1 case). Metastases are rare. Multiple cerebral aneurysms (3 cases) did not lead to haemorrhagic complications.

We studied 10 neurologically normal patients (8 females, 2 males) aged 8-30 years (mean 17 years) who had recurrent episodes if visually induced occipital seizures. Television and computer screens were the main triggers. Seizure onset occurred between the ages of 5 and 17 years (mean 11 years). All seizures were stimulus related and began with elementary visual symptoms, followed in most patients by a slow clustering of cephalic pain, epigastric discomfort, and vomiting, with either normal of only mildly impaired responsiveness. EEG features included normal background activity, occipital spikes and waves, and a photoparoxysmal response which could be occipital, generalized, or both. Four patients also showed spontaneous generalized epileptiform abnormalities, and 3 had rolandic spikes. An Oz electrode was critical in identifying epileptiform activity in some patients. Complete seizure control was achieved in most patients with monotherapy, although occasional stimulus-related seizures occurred in 3 patients who showed a wider range of photosensitivity. These patients have an idiopathic localization-related epilepsy with age-related onset and specific mode of precipitation. Although this type of epilepsy has been reported previously, it has remained underrecognized, probably because it is difficult to differentiate clinically from migraine or from nonreflex childhood idiopathic occipital epilepsy.
