The authors describe the electro-clinical state of four children having a type of epilepsy clinically characterized by rare partial motor seizures and frequent absences. From E.E.G. point of view they had focal (mainly frontal) and diffuse abnormalities. Such diffuse abnormalities became continuous during slow sleep, thus realizing an electrical status epilepticus. During such status partial subclinical seizures were recorded. At the onset such cases have electroclinical features resembling those observed in the form of epilepsy so-called "benign partial epilepsy of children with rolandic or mid-temporal foci". All cases, however, have behavioural problems (instability, desorientation) and decreased school performances. The epilepsy evolution, however, is favourable and such form should consequently be distinguished from the Lennox-Gastaut Syndrome.

The clinical trial of Dipropylacetat (Convulex) demonstrates the advantages of a well organized multicenter-study. In rather short time reliable information concerning indication, compatibility and dosage can be received. The results of this project are similar to other observations dealing with DPA: Good therapeutical effect in primary generalized epilepsies independent of the seizure-type. Astonishing results influencing Lennox-Syndrome. In cases not treated before, Convulex shows at least the same effect than the "standard anticonvulsants" but less side effects, especially sedation. In those untreated "new-comers" therapeutical effect comes earlier than in cases of premedication. 20 to 50 mg/kg/day can be recommended in childhood. In rare cases the dosage was increased up to 120 mg/kg/day without problems.

Newer imaging methods, particularly MRI, are recognizing increasing numbers of frontal static and progressive lesions in patients in whom recurrent seizures are the presenting and only symptoms. Surgical results in terms of controlling frontal seizures are improving and becoming comparable to those achieved in the temporal lobe. The results following removal of discrete frontal lesions are superior to those with more diffuse lesions or without demonstrable lesions. Stereotaxic surgery and microsurgical techniques are allowing safer excisions from formerly inaccessible areas or adjacent to areas of essential function. These advances have increased the number of candidates who benefit from successful frontal lobe surgery. The types of clinical seizures in patients with discrete local frontal lesions usually conform with five of the seven anatomically named seizure types described in the 1989 International Classification of Epilepsies and Epileptic Syndromes (supplemental motor seizures, anterior frontopolar region, dorsolateral, and motor cortex). Too few cases with discrete lesions were found with sufficiently detailed seizure descriptions of possible orbitofrontal and cingulate origin to allow separate categorizations. In those cases symptoms and signs, such as autonomic, mood and affect, gestural automatisms, and versive movements preceding the automatisms, did not seem to differentiate orbitofrontal and anterior cingulate lesion cases from each other or from those in other areas of the anterior third of the frontal lobe.

In 1957, Landau and Kleffner reported six cases of a "syndrome of acquired aphasia with convulsive disorder". Since this first report more than 130 cases with acquired language disabilities with EEG-abnormalities have been described. Comprehension of language is primarily affected, spike discharges are predominantly found in temporal regions. Facultative symptoms are epileptic seizures and psychiatric disorders. The paper gives a review of the literature describing the clinical manifestations, the therapeutic procedure, the prognosis and the etiological factors of this syndrome, which is even listed in the last version of the ICD-10 and the International Classification of Epilepsies and Epileptic Syndromes.

The utility of the "International Classification of Epilepsies, Epileptic Syndromes, and Related Seizure Disorders," proposed by ILAE in 1989, was investigated in a neuropsychiatric clinic with a patient population numbering 300. Two hundred and three patients (67.7%) had localization-related epilepsies (LRE), including one idiopathic case. Sixty-six patients (22%) had generalized epilepsies, 50 idiopathic, 2 Lennox-Gastaut syndrome, and 14 symptomatic. Thirty-one patients (10.3%) with generalized tonic-clonic seizures occurring only during sleep had the epilepsies undetermined whether they are focal or generalized. In the symptomatic LRE cases, 34 cases could not be classified, and 7 of the cases with frontal lobe epilepsies were difficult to subtype. Eleven of the symptomatic LRE cases had some independent seizures, multiple foci in surface EEGs and were intractable. These cases may be defined as "multifocal epilepsies."

The mechanism of epileptic seizures so far remains unclear. Immunological disturbances may be one of the possible mechanisms. The assumption that primary epilepsy is an autoimmune disease lacks an experimental basis. In order to search any relationship between generalized epileptic seizures and autoimmune we examined and measured the serum anti-acetylcholine receptor antibody (A AchR Ab) and anti-synaptic premembrane antibody (A PrM Ab) in 12 patients with typical absences, 20 patients with generalized tonic-clonic seizures (GTC) and 6 patients with Lennox-Gastaut Syndrome. 2 (16.7%) out of 12 patients with absences showed positive both A AchR Ab and A PrM Ab, positive A AchR Ab in 1 patient. Among 20 patients with GTC both A AchR Ab and A PrM Ab were positive in 7 patients (35%), A PrM Ab was positive in 1 patient. Totally in 8 patients A PrM Ab was positive. However, the difference between the two Antibodies was not significant (1.1:1). The two kinds of antibody were positive in 5 (83%) out of 6 patients and A PrM Ab was positive, but A AchR Ab was doubtful in another one patient with Lennox-Gastaut syndrome. Therefore, all the patients with Lennox-Gastaut syndrome showed positive antibody. Our data suggested that different types of generalized epileptic-seizures showed different severity of autoimmune dysfunction. The meaning of this kind of immune dysfunction needs further investigation.

In 1989/90 a follow-up was made possible on 72 of 78 patients who have been treated for the supposed or confirmed diagnosis of a Lennox-Gastaut-Syndrome at the university children hospital of Berne between 1964 and 1978. Nine patients were excluded of this study because the diagnosis was proved wrong retrospectively, leaving 63 cases. Of these, eleven patients (17.5%) have died. The remaining 52 (82.5%) were evaluated regarding their epilepsy, psychomotor development and social adaptation. The follow-up was good for 14.3%, intermediate for 23.8% and poor for 44.4%. Bad prognostic factors were found to be: first manifestation of epilepsy during the first year of life, occurrence of infantile spasms or hypsarrhythmia in the EEG and pathological neurological signs at the beginning of the disease. In the course of illness a change of seizure phenomenology was observed. The infantile spasms were seen only during the first three years of epilepsy. After the second year of disease psychomotor seizures became more and more frequent. Atypical absences, already seen at the beginning, were the most frequent form of seizure from the third year of epilepsy until the end of our observations. During the course of disease the frequency of generalized tonic and tonic-clonic seizures decreased little.

We attempted to classify, according to the International Classification of Epilepsies and Epileptic Syndromes, 986 patients consecutively examined during a 13-month period either in a specialized private practice (n = 642) or in an adult neurology unit in a university hospital (n = 344). Without major difficulty, we classified 97% of patients in more or less clearly defined syndromes. Benign frontal and benign psychomotor epilepsies of childhood were represented in this sample of patients. In either partial or generalized idiopathic epilepsies, a diagnosis of epilepsy appears justified even after a single epileptic event when sufficient electroclinical characteristics are present. Patients with symptomatic generalized epilepsies often have to be classified under two or three headings. Many children with a symptomatic generalized epilepsy also experience partial seizures. Alcoholic epilepsy is described as a veritable epileptic syndrome. The distribution of epileptic syndromes was clearly different in the two samples, casting doubt on the value of some epidemiologic surveys based on selected groups of patients.

We studied 40 patients with temporal lobe epilepsies who had long-term intracranial EEG recordings and temporal lobectomies. They were divided into 3 groups on the basis of the anatomical site of seizure origin. An electrode implantation technique combined intracerebral depth electrodes with subdural strip electrodes. The seizures were of amygdalo-hippocampal origin in 18 patients, lateral temporal in 13 patients, and temporo-basal in 9 patients. The clinical and EEG features were reviewed retrospectively with regard to 3 factors in each patient: localization of interictal spikes in the scalp-recorded EEG, signal symptoms (auras), and presumed etiologies. Epilepsy with amygdalo-hippocampal and lateral temporal seizures was found to be distinguishable by the electroclinical features. It seems practical to classify these 2 subtypes of temporal lobe epilepsies as in the 1989 Classification of Epilepsies and Epileptic Syndromes. Temporal lobe epilepsies thus defined can be regarded as epileptic syndromes rather than a cluster of seizure manifestations.

Temporal lobe epilepsy with amygdalohippocampal seizures may have episodes of severe convulsions in childhood more frequently and the onset age is significantly lower compared to epilepsy with lateral temporal seizures. To the contrary, tumorous lesions are found more frequently in epilepsy with lateral temporal seizures. In view of the presumed known etiologies in relation to the localization of epileptogenic foci, the Classification of Epileptic Syndrome (1989), subdividing temporal lobe epilepsies into 2 groups, was found to be useful.
