An uncontrolled trial of sodium valproate in 25 severe epileptics uncontrollable by conventional antiepileptic drugs is presented. Excellent control was achieved in petit mal, myoclonic and minor motor seizures. No serious side effects were encountered, but hyperactivity may be aggravated and interaction with other anticonvulsants does occur.

The marriage rate of epileptic patients was 62% in males and 78% in females. Compared with the rates in the general population, the male patients had a 15% lower rate, but there was no difference in females. There were 263 patients with at least one offspring selected for the study. There were 234 sons and 272 daughters (506 total, 1.9 per patient). Distribution by types of seizure was awakening grand mal, absence or myoclonic petit mal in 24%, grand mal with no aura in 21%, grand mal during sleep in 23%, diffuse grand mal in 7%, grand mal with aura in 13%, psychomotor seizure in 9%, and focal seizure in 3%. The probands were composed of 79% idiopathic and 21% symptomatic in pathogenetic classification. An epileptic EEG abnormality was demonstrated in 22% of male and 44% of female probands. The incidence of seizures among offspring was 2.4% (4.2% age-corrected) in a narrow sense (epilepsy) and 9.1% in a broad sense including febrile convulsions. The latter morbidity was 11.0% for the idopathic and 3.2% for the symptomatic group; 11.0% for female and 6.9% for male probands; 10.2% for sons and 8.1% for daughters. The figure was higher for the probands with the age range at onset of seizure of 0--4 years (20.6%) and 20--29 years (12.6%) than for those with other age ranges; higher for those with awakening grand mal, absence, myoclonic petit mal, for those with family history of epilepsy than those without it. Possible correlation of types of seizure between probands and offspring was demonstrated. Thirty-seven percent of offspring exhibited epileptic EEG abnormalities, and the ratio of epileptic EEG abnormalities to clinical manifestation is about 4:1. Possible existence of familial aggregation of EGG abnormalities and of two kinds of families with large or small epileptic predisposition was indicated. The importance of the role of hereditary and environmental factors in epileptic pathogenesis is proved, and the results of an investigation of congenital malformation among offspring of epileptic mothers are presented. These results were considered to be useful for genetic counseling of epileptic patients.

Sodium valproate (Epilim) has been used in the management of 100 patients with previously uncontrolled epilepsy for periods up to 2 years. If all manifestations of epilepsy are considered together, 75% to 100% control of seizures was achieved in 43% of patients, 25% to 74% control in 26%, and no improvement occurred in 31% of patients. Control of 75% to 100% was achieved in 57% of patients with a spike and wave electroencephalogram (EEG) disturbance but only in 35% of those with focal abnormalities, excessive slow activity, or normal records. When the various manifestations of epilepsy were considered individually, the greatest improvement was found among the patients with the minor forms of generalized epilepsy (petit mal absences, myoclonus and atonic attacks) in whom 75% to 100% control was obtained in 67%, compared with 43% of those with major generalized seizures (grand mal) and 30% of those with temporal lobe attacks and other forms of focal epilepsy. Gastrointestinal disturbances and drowsiness were noted as side effects in the early stages of treatment, but the majority of patients tolerated the drug well and many commented on increased mental alertness while taking it. Two patients were over-stimulated and some noticed tremor or twitching as side effects. Some minor abnormalities in blood coagulation studies were noted, but these were transient and did not appear to be of clinical significance. Regular blood counts and biochemical studies have not shown any significant changes. Sodium valproate appears to be a safe and useful anticonvulsant with the advantage that it usually makes patients brighter rather than drowsier. Abnormalities of platelet function have been described in some overseas reports, so that any unexplained bruising or bleeding in a patient taking valproate is an indication for a platelet count and coagulation studies.

Interrupting petit-mal status in infantile myoclonic seizures (n = 11), Lennox syndrom (n = 32), and in myoclonicastatic petit mal (n = 13) diazepame (Valium) and clonazepame (Rivotril) have been injected intraveneously in 56 patients during continuous EEG monitoring (38 patients with diazepame, 18 patients with clonazepame) (Table 1). A judgement according to the EEG findings and the apparent vigilance was performed thirty minutes after the injection was completed (Fig. 1 und 2; Table 3). Following results are presented: 1) There are no significant differences between clonazepame and diazepame with respect to therapeutic success (Table 3). 2. There are almost no differences concerning therapeutic success in the three forms of petit-mal status listed above (Table 3). 3) The initial success was 57%: 46% in infantile myoclonic seizures, 56% in Lennox syndrome, 70% in myoclonic-astatic petit-mal. The number of relapses for all forms was high: On the day following the injection only 18% of all patients did not show continued petit-mal-status: 18% in infantile myoclonic seizures, 15% in Lennox syndrome, 23% in myoclonicastatic petit mal (Table 3). 4) 13 patients were no longer in a status on the following day. 3 children were out of status spontaneously, independent from the intravenous application, 4 patients, one with infantile myoclonic seizures and 3 with Lennox syndrome, showed a focal EEG, 6 patients, 2 with infantile myoclonic seizures, 3 with Lennox syndrome, 4 with myoclonic-astatic petit mal, were further demonstrating generalised paroxysms (Fig. 1 und 2). 5) In infantile myoclonic seizures and in the Lennox syndrome almost always a focal EEG could be seen that accompanied the decrease of generalised paroxysms (hypsarrhythmia or 2/sec slow wave and spike). This finding has not been seen in the myoclonic-astatic petit mal, another sign that the latter is of primary generalised, "centrencephal" origin in contrast to the first two forms of convulsive disorders (Fig. 1, 2).

Petit mal epilepsy is primarily a disorder of childhood. It is a comparatively rare type of seizure and is relatively benign. It rarely causes demonstrable evidence of pathologic cerebral changes, except in patients who have frequent attacks of petit mal status. Patients with petit mal epilepsy are prone to develop major motor (grand mal) seizures. Therefore, concurrent administration of petit mal and major motor anticonvulsants is recommended.

Six patients ranging in age from 42 to 69 with no prior history of seizure disorder presented an acute prolonged or intermittent confusional state, with or without psychotic symptoms, as an ictal manifestation. The EEGs demonstrated protracted generalized spike and wave discharges, but full diagnostic evaluation disclosed no evident cause for the seizures. All promptly responded to small amounts of intravenous diazepam and subsequent oral phenytoin and phenobarbital. Three of the six patients had focal spike or sharp wave discharges on EEGs recorded subsequently, suggesting that the episodes may reflect secondary generalized seizures in some cases. These cases do not fit in the classic category of petit mal status and appear to be a distinct entity.

A synthetic procedure for the preparation of imidazolidinediones by the base-catalyzed cyclization of propargylureas is described. This method appears to be the most versatile way of obtaining these compounds containing tertiary groups substituted on ring-nitrogen number 3. One of these derivatives, 3-tert-butyl-5,5-dimethyl-2,4-imidazolidinedione (1a), has shown a moderate level of subcutaneous metrazole seizure threshold activity (scMet indicates potential for control of petit mal epileptic seizures) in control screens on mice, as determined by the National Institute of Neurological and Communicative Disorders and Stroke.

In freely moving cats the behavioral and EEG-shifts, accompanied by myoclonic jerks with slow negative waves and spike-wave complexes in the cortexand caudate nucleus, were recorded following a single intramuscular injection of high penicillin doses. The stimulants of catecholaminergic transmission (L-DOPA and apomorphine) inhibited the development of such phenomena but facilitated origination of tonicoclonic cramps. The inhibitors of catecholaminergic synapses (aminazin and haloperidol) exerted reverse effects. The electrolytic injury to the caudate nucleus head also prevented formation of petit mal-like seizures while the threshold low-frequency stimulation of the nucleus increased penicillin effect.

Two case reports illustrate the therapeutic response of congenital nystagmus to a diet eliminating synthetic food colors, synthetic food flavors, the antioxidant preservatives butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA), and a small group of foods thought to contain a natural salicylate radical. A brief discussion of the hyperkinetic syndrome is offered with the proposal that a variety of neurologic and neuromuscular disturbances (grand mal, petit mal, psychomotor seizures; La Tourette syndrome; autism; retardation; the behevioral component of Down's syndrome; and oculomotor disturbances) may be induced by identical chemicals, depending upon the individual's genetic profile and the interaction with other environmental factors. It is perhaps the failure to integrate all the signs presented by the various clinical patterns with hyperkinesis or Minimal Brain Dysfunction (MBD) under a single heading that eye muscle involvement manifested as either nystagmus or strabismus has not been emphasized as part of the hyperkinetic syndrome.

An intrinsic asymmetry of nigrostriatal dopamine system postulated to be responsible for motor imbalance in normal rats (Glick et al., 1976) is believed to create asymmetry of arousal-sensitive wave-spike discharges. In the present study, bilaterally recorded pentamethylenetetrazol (PMZ)-activated wave-spike discharges were correlated with circling behavior in intact rats. Thirteen naive rats (10 male, 3 female) were implanted with electrodes symmetrically placed over the visual cortices, and their rotation directionality was assessed in the rotometer subsequent to administration of d-methamphetamine sul-ate, 1.5 mg/kg, i.p. In 9 rats a PMZ injection, 20 mg/kg, i.p., revealed asymmetric wave-spike bursts. All of them reliably rotated in the dirction opposite to the hemisphere with lower amplitude wave-spike discharges. It is believed that the nigrostriatal dopamine system plays a major role in modulating the asymmetry of wave-spike seizures. The findings are discussed as they relate to asymmetric generalized wave-spike dischanges found in certain petit mal patients.
