The objective of this study was to establish the etiology of epilepsy in 210 chronic epileptics (110 female, 100 male), aged 14-82 years (34.2 +/- 13.3). Patients less than 10 years-old and alcoholism were excluded. All underwent neurological examination, routine blood tests, EEG and CT-scan. Twenty patients (10.5%) were submitted to spinal tap for CSF examination. Neurological examination was abnormal in 26 (12.4%), the EEG in 68 (45.5%), and CT-scan in 93 (44.3%). According to the International Classification of Epileptic Seizures (1981), 101 (48.1%) have generalized seizures, 66 (31.4%) partial seizures secondarily generalized, 25 (11.8%) simple partial and complex partial seizures, and 14 (6.6%) generalized and partial seizures. Four patients (2.0%) could not be classified. In 125 (59.5%) patients the etiology was unknown. Neurocysticercosis accounted for 57 (27.1%) of cases, followed by cerebrovascular disease 8 (3.8%), perinatal damage 5 (2.4%), familial epilepsy 4 (1.9%), head injury 4 (1.9%), infective 1 (0.5%), and miscelanea 6 (2.8%).

Twenty seven cases (13 male, 14 female) in the age group of 3-12 years with cerebral cysticercosis were studied and followed up to 3.9 years (mean 1.85 +/- 0.91 years). Seizures (partial 76% and generalized 23.8%) was the feature in 21 patients (77.7%) and raised intracranial tension in 15 (55.5%). Five patients (18.2%) had meningoencephalitis, while 4 (14.8%) had obstructive hydrocephalus due to intraventricular cysts in the 4th ventricle. Twenty two patients received cysticidal drugs (praziquantel or albendazole), while 8 had surgical intervention (CSF diversion, cyst removal, subtemporal decompression or extirpation of the cortical cyst). Mortality was 18.2%. Survivors had epilepsy in 18 patients (81.8%), dementia in 2 (9%), mental subnormality in 6 (27.2%) and hyperkinesia in 12 (54.5%).

We report the preliminary results of an ongoing study of multiple sclerosis (MS) in childhood. The investigations include an analysis of the clinical picture and course. Multiple sclerosis in early childhood may present atypically, with a symptomatology suggesting diffuse encephalomyelitis, meningeal reaction, brain oedema, seizures, impaired consciousness and in some cases take a lethal course. Imaging studies including MRI and MR-spectroscopy, CSF-analysis, electrophysiology (VEP, BAEP, SER), and virological and immunological investigations are performed. So far 15 children have been studied. Their age at the onset of the disease ranged from 3 to 15 years. Abnormal CSF-findings with pleocytosis and oligoclonal IgG bands were present in 11 and 10 out of 15 patients respectively. MRI revealed numerous white matter lesions in the brain stem and cerebral hemispheres. VEP, BAEP and SER's were abnormal in most children. Proton magnetic resonance spectra from plaques exhibited a 50-80% decrease in N-acetyl aspartate, which is a potential marker of vital neuronal tissue, a decrease of the creatine pool and an increase of choline-containing compounds. Lactate was not increased. Our observations of MS in early childhood cast doubt on some of the previous notions concerning a latency period of several years between the exposure to a still unknown agent and the manifestation of MS. In view of atypical features in the initial phase, it would seem desirable to record cases of encephalomyelitis of undetermined origin as potential cases of MS and to register the further course for verification or exclusion.

A retrospective study of 36 confirmed cases of subacute sclerosing panencephalitis (SSPE) was carried out to detect any variation in the clinical and EEG patterns previously described. There were 31 males and 5 females, aged 4 to 24 years. Onset of SSPE at or after 15 years of age was observed in 22.2% of cases. Rapid progression of the disease was observed in 52%. The first symptom was myoclonus in 61.6%, mental regression in 22.2% and generalised seizures in 11.1% of cases. Low positive measles antibody titres in the CSF were found in 36.1% of cases. EEG analysis revealed slow background in 69.2% and periodic complexes in 94.4% of cases. Atypical periodic complexes, focal abnormalities and paroxysms of bisynchronus sharp activity were also observed.

A total of 21 cases of childhood neurocysticercosis seen over five years (1985-89) at JIPMER hospital Pondicherry, are reported. Nine of these patients were males and twelve females. Their age ranged between 5 to 15 years. The presenting features were convulsive seizures (14), features of raised intracranial pressure (6) and meningoencephalitis syndrome (1). Diagnosis of neurocysticercosis was based on positive CSF serological tests (11), CT morphology (11), brain biopsy (1) and autopsy (1). Praziquantel therapy was given in 4 cases, 3 of them showed remarkable improvement in neurological status and one died of acute reaction.

The cases of three patients with focal seizure associated to non-cetotic hyperglycemia are reported. Two patients presented motor epilepsy partialis continua (EPC). One case showed EPC as the first clinical manifestation of diabetes mellitus. Neurological exam was normal in all patients. CT and CSF were normal in the cases they were evaluated. Scalp EEG registered during a focal seizure revealed a bilateral temporal spiky activity. Glycemia levels were 455, 660 and 439 mg/dl. Two patients presented hyponatremia simultaneously. No patients had benefit with phenytoin or diazepam, and one patient got worse after them. Seizure control occurred after insulin and electrolytic treatment. It is important to diagnose this type of condition to avoid changes of non-cetotic hyperglycemia syndrome in a hyperosmolarity and coma state, disturbance which brings a higher mortality.

Tryptophan (Trp), 5-HTP, 5-HT, 5-HIAA, HVA, and MHPG in CSF and total Trp(T-Trp), free Trp(F-Trp) and serotonin in serum were determined in 80 children with epilepsy and also in a control group. It was found that Trp, 5-HT, 5-HIAA in CSF and F-Trp in blood decreased in children with epilepsy. But the decrease of F-Trp was not the main cause of decreased 5-HT metabolism, because the no positive correlations among the four substances were found. Each of them returned to normal levels after the treatment with phenytoin or valproate. 5-HT concentration was negatively correlated with the frequency of the epilepsy episodes. 5-HIAA and HVA levels were relatively higher in the epileptics with brain damage as with compared with those who had no brain damage. The MHPG level was higher in the patients simple partial seizures. Complex partial epileptics and those patients receiving antiepileptic drugs had a lower serum T-Trp level. T-Trp was negatively correlated with the serum valproate concentration. Both T-Trp and F-Trp levels decreased in the patients treated with phenytoin.

A case of mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes, in which a pituitary growth hormone (GH) secretion deficiency of hypothalamic origin was revealed through neuro-endocrinological examinations, was described. The case was a 10-year-old girl, who had been suffering from generalized tonic seizures since age 5, four episodes of alternating hemiplegia since age 6, stunted growth since age 7, and simple partial motor seizures as well as gelastic seizures since age 8. Marked elevation of lactate and pyruvate in both serum and CSF, abundant ragged red fibers in biopsied muscle, and low density areas in the left occipital lobe and bilateral globus pallidus in addition to diffuse brain atrophy on CT scan and MRI of the head were demonstrated, although the activities of muscle enzymes complex I-IV were within normal ranges. Pituitary GH secretion was deficient under the loadings with insulin, L-DOPA, sleep, and a single growth hormone releasing factor (GRF) administration, but normal GH response was registered under the repetitive stimulation with GRF. Activities of other hormonal axes were normal. It is likely that short stature commonly observed in MELAS patients is due to hypothalamic dysfunction, which might be brought out by chronic ischemia and energy deficiency of the diencephalon based upon mitochondrial abnormality of that region. It is likely that gelastic seizure in this case is due to hypothalamic dysfunction.

We report a 14-year-old boy with mitochondrial myopathy, encephalopathy, lactic acidosis, and strokelike episodes (MELAS) who presented repeated episodes of abdominal pain and vomiting since the age of 8 years. In addition, he developed strokelike episodes with myoclonic seizures and transient hemiplegia on three occasions. At the age of 14-1/12-years, he also developed epilepsia partialis continua persisting for 10 days, which was associated with myoclonic seizures synchronized with spike discharges at the right central area. Laboratory examination disclosed increased levels of lactate and pyruvate in serum and CSF and low density areas in the bilateral temporal regions on CT scan. Muscle biopsy showed scattered ragged-red fibers. The enzyme activities (pyruvate dehydrogenase complex, pyruvate carboxylase, phosphoenol pyruvate carboxykinase, and cytochrome c oxidase) and the rates of decarboxylation of [3-14C]pyruvate in cultured skin fibroblasts were within normal ranges.

By means of RIA, the contents of Leu-enkephalin, Met-enkephalin, and Beta-endorphin in CSF of 32 epileptic patients and 24 controls were determined. It was found that the mean Leu-enkephalin content in CSF of the epileptic patient group was significantly higher than that of the control group (P less than 0.01), whereas the mean contents of Met-enkephalin and Beta-endorphin in CSF showed no significant change as compared with those of the control group. The increase of Leu-enkephalin was not related to such factors as type of seizure, age of onset, length of time after the last seizure, taking of antiepileptic drugs, and abnormality in cranial CT manifestation. This suggested that endogenous opioid peptides might take part in the neurochemical mechanism of human epilepsy, and leu-enkephalin could play an important role in the development of epileptic episodes.
