Total creatine kinase (CK) activity in serum was increased post-ictally in 14 out of 17 patients (82%) admitted to the hospital after one or more generalized seizures. No correlation was found between increased CK levels and cerebral or extracerebral ictal injuries. A highly significant negative correlation exists between regular anti-epileptic treatment and elevated levels of the enzyme (p less than 0.01). The maximum value of CK activity was found on the 3rd or 4th post-ictal day in 10 out of 14 patients. Correspondingly, late CK-activity increases on the 2nd-4th post-ictal day were found in 6 out of 9 experiments with unrestrained cats. In cats immobilized by relaxant drugs, only an initial rise of the enzyme within 24 h after the electrographic seizures was observed. These findings suggest that sources other than the skeletal muscle alone contribute to the increased CK activity after grand mal seizures.

In this series of one hundred and twenty-eight adults with Down's syndrome nearly half (i.e. 42.2 per cent) developed a normal EEG. This would appear to bear out the findings of Gregoziades and Pampiglione (1966) that older children with this syndrome tended to have tracings similar to the normal child. The youngest age group of fifteen to twenty-four years developed a normal tracing in 38.9 per cent of cases. The most frequent abnormality was an excess of theta, in keeping with the suggestion of Godinova and Hirai and Izawa that this was due to immaturity. Neither the presence of congenital heart disease nor diabetes nor intercurrent illness appeared to have any effect on the development of seizures. Epilepsy developed at any time during adult life but, not surprisingly, the five cases developing it had shown sharp or paroxysmal activity previously. Two had suffered from fainting attacks. In one, the diagnosis was confirmed later by a typical grand mal seizure and the other by response to anticonvulsants. Neither suffered from congenital heart disease.

A 62-year-old woman developed neurologic deficits 7 months after pulmonary lobectomy for alveolar cell carcinoma of the lung. CT scan of the head demonstrated two metastases with marked peritumoral edema. Administration of Decadron, chemotherapy and 3,000 rad cranial radiation resulted in dramatic improvement of dysphasia and right hand paresis. Almost 2 months later, rhythmic, involuntary movements of the left hand developed. There was progression to multifocal seizures, grand mal seizures, postictal depression, status epilepticus, and coma, with death 9 days after onset of the movement disorder. Bronchoalveolar carcinoma was widely disseminated in lungs and bones, and as three metastases in brain. Bland "ischemic" necrosis in a pseudolaminar pattern was present in the neocortex. Innumerable Cowdry type A intranuclear inclusion bodies were seen in neurons, astrocytes, and oligodenodroglia. Immunofluorescence demonstrated Herpes simplex virus type 2 antigen and electron microscopy revealed virions with the morphology of the Herpes group. The case is significant for (1) the concurrence of intracranial metastases and Herpes simplex encephalitis, and (2) the causal agent, Herpes simplex virus type 2. The implication for the clinical neurocientist is the potential in a patient with systemic cancer, for the causation of neurologic complications by more than one factor or mechanism.

Eight patients developed grand mal seizures during intravenous theophylline therapy. None had a history of neurologic disorder, and all were acutely ill with severe pulmonary or cardiovascular disease, or both. Serum theophylline concentrations obtained within 1 hour of the seizure ranged from 25 mug/ml to 70mug/ml, with a mean value (53 plus or minus 4.8 mug/ml) more than twice the upper limit of the recommended therapeutic concentration. This serum theophylline concentration was greater than the concentration found in a group of patients with less severe drug-related symptoms (35 plus or minus 1.8 mug/ml, P less than 0.01). A third group of patients without drug-related symptoms had a mean theophylline serum concentration of 19 plus or minus 2.0 mug/ml, which was less than that found in either group with toxicity symptoms (P less than 0.05). Factors predisposing to the high serum concentrations in the patients with seizures were both higher drug dosage, compared with the other groups (P less than 0.01), and hepatic dysfunction, which was more common in both groups with drug-related symptoms.

Eighty-five patients were admitted to the hospital under the preliminary diagnosis of epileptic seizures. None of them had more than five seizures before admission. Sixty-five of these 85 patients had a neurological and electroencephalographic follow-up examination 5 to 7 years later. Another 8 had been readmitted before. From these 8 the diagnosis of cerebral tumor was made in 3 patients. In almost half of the remaining 70 cases the etiology of seizures remained uncertain. The leading known etiologic factors were chronic alcoholism, head injury and perinatal brain damage. Before admission seizures recurred once or twice a year in most patients. After discharge from the hospital 25 patients were without further seizures, 15 of the seizure-free group never received anti-epileptic treatment. The remaining 10 were without medication for a period of time before the follow-up. All seizure-free patients were given the diagnosis of very rare grand mal seizures or seizures of uncertain origin. Only two of the untreated group (total of 17) had seizures after discharge. These findings show that recurrence of seizures was predictable, when patients were discharged. Predictors of recurrance were "treatment" or "no treatment" given initially. Antiepileptic medication should be given in cases of one seizure or more a year, when epileptic origin is certain. Very rare seizures and seizures of uncertain origin may stay without antiepileptic treatment. Sporadic seizures are benign in most cases - comparable to seizures of late onset. Both groups overlap.

This survey covers 74 patients with temporal lobe epilepsy, resistant to medication, who underwent unilateral temporal lobectomy during the years 1960-1969 at Rigshospitalet, Copenhagen. Preoperatively all patients were socially incapacitated. In all patients a unilateral or predominantly unilateral temporal EEG focus was found. No tumour or gross vascular malformation had been recognized before or during operation. At follow-up 45 patients were free from seizures. A further 15 had obtained a reduction in their seizure frequencies by at least 75%, while the remaining 10 survivors, only obtained a slight improvement or remained unchanged. There were four deaths. The operation also favourably influenced the psychiatric status, which was found closely related to relief from seizures. Prognostically favourable factors were: i) preoperative presence of a single type of seizure, ii) duration of epilepsy of less than four years, iii) operation in or before early adulthood, iv) an anterior temporal or sphenoidal electrode focus, or both, on the EEG. The prognostically unfavourable factors regarding complete relief from seizures were: i) preoperative presence of grand mal, ii) age at onset of epilepsy or of the first grand mal seizure between 5 and 19 years of age, iii) preoperative duration of epilepsy of over ten years and of grand mal of over one year. Prognostically unfavourable factors regarding psychiatric normalization were: i) preoperative presence of psychosis, ii) ictal-affective attacks or automatisms of a complex nature, iii) impairment of intellectual functions. The eventual neuropathological conclusion was that the more specific and circumscribed the histological abnormality the better the final outcome. The social rehabilitation was found to be significantly improved by operation at an early age.

The effect of an antiepileptic drug, valproic acid (VPA), on an experimental form of epilepsy, the kindling phenomenon, is described. In cat, 50 mg/kg i.p. per day is sufficient to block the progressive establishment of generalized seizures produced normally by repetitive electrical stimulation of the amygdala. However, a focal afterdischarge persists during the entire treatment. Higher doses (75-150 mg/kg) are necessary to protect the animal against the generalized tonic-clonic seizure when the kindling phenomenon is established. These effects and the action of barbiturates, which was also tested, seem to attribute to VPA a complex role in the mechanism of this action.

Depakine Labaz in doses from 30 to 1200 mg daily was given to 52 patients in an outpatient clinic. In 13% of cases symptoms of drug intolerance developed and the treatment had to be discontinued. In 45 cases treatment was continued. The drug was given usually to patients refractory to previous drugs, with evidence of organic brain disease. The highest degree of clinical improvement was observed in patients with grand mal seizures and seizures without convulsions. The influence of this treatment of partial complex seizures was slightly smaller. The number of patients treated was too small for evaluation of the effects in partial simple seizures. The total proportion of improved patients was about 60%. In EEG curves normalization of background activity was the most frequent findings, without appearance of rapid activity. In some cases manifestation of focal changes was observed. The favourable effect of Depakine on seizure activity manifested itself in later period of treatment and was slight. The drug had a favourable effect on the wellbeing of patients and had no significant toxic effect in the liver or kidneys.

79 patients with primary generalized epilepsies have been treated with DPA in a medium dosage of 51 mg/kg bodyweight/day, range 14 to 125 mg/kg/day, for a medium time of 22 months, range 2 to 49 months. 51 children out of this group had been treated previously and were therapy resistant to other medications. 27 children got DPA for their first medication. 34 patients were treated with DPA as a single drug, 45 were treated in combination with other medications. Therapeutic success was found to be remarkable good in impulsive petit mal (n = 4, all patients without any more seizures), in absences (n = 52, complete success in 84%), and in primary generalized grand mal seizures with spike-waves in the EEG alone or in combination with petit mal (n = 30, 87% success). However, centrencephalic myoclonic-astatic seizures (n = 17, no more seizures in 35%) were influenced significantly less. Side effects were rarely seen, mostly they could be observed in those patients treated with DPA and another medication. Side effects never induced interruption of treatment with DPA.
