Although the first descriptions of the syndrome did not report seizures, their association with epilepsy is relatively common. METHODS: were evaluated 68 individuals with DS and 83 with non-syndromic mental retardation (N-SMR). All patients underwent digital EEG, lasting at least 30 minutes and electrodes positioned according to the International 10-20 System of Electrode Placement. Data were analyzed using descriptive statistics and proportions were compared with Student's t-test and test of Differences between Proportions with p<0.05 considered statistically significant. RESULTS: DS: 27.9% had epilepsy (first seizure with 2.2±3.7 years). Fifteen (22.1%) patients had epileptiform discharges, 5 (7.4%) hypsarrhythmia, 5 (7.4%) focal pattern, 3 (4.4%) generalized pattern and 2 (2.9%) multifocal pattern. N-SMR: 33.7% patients had epilepsy (first seizure with 1.2±4.5 years). Twenty-three (27.7%) patients had epileptiform discharges, 10 (12.0%) focal pattern, 5 (6.0%) generalized pattern and 8 (9.6%) multifocal pattern. CONCLUSION: The difference between the occurrence of epilepsy in DS and N-SMR was not statistically significant, as well as between normal EEG, EEGs with focal pattern, generalized pattern and multifocal pattern. In SD group 7.4% have shown hypsarrhythmia.The comparison with N-SMR was not possible because none of these has shown this EEG abnormality.","PeriodicalId":274261,"journal":{"name":"Journal of Epilepsy and Clinical Neurophysiology","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116988921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Epilepsy has early onset and is usually medically refractory. Etiology and pathophysiological mechanisms are unclear. The EEG can present disorganization and slowing of background activity and multifocal and/or generalized epileptogenic discharges. OBJECTIVE: To report the difficulties and challenges of neurosurgical treatment of a hypothalamic hamartoma in an infant. CASE REPORT: Infant with seizures since eight months old of age. The neurological investigation revealed a lesion in tuber cinereum suggestive of hamartoma. The epilepsy evolved with resistance to antiepileptic drugs, requiring neurosurgical procedure. The endoscopic resection could not be performed because the hamartoma was firmly attached to the hypothalamus. Currently, the child remains with tonic, clonic and atonic seizures. DISCUSSION: Lesionectomy performed by microsurgery or radiosurgery seems to be the most effective treatment for seizure control in patients with hypothalamic hamartomas who do not respond to clinical treatment. Callosotomy may be effective in selected cases, and lobectomy/cortical resections are not related to seizure control. In some patients, particularly in infants, lesionectomy and radiosurgery may be technically unfeasible.","PeriodicalId":274261,"journal":{"name":"Journal of Epilepsy and Clinical Neurophysiology","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126330714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experimental studies have shown that metallothioneins I/II (MT-I/II), which chelate free zinc, can affect seizures and reduce neuronal death after status epilepticus. Our aim was to evaluate the expression of MT-I/II in the hippocampus of patients with temporal lobe epilepsy (TLE). Hippocampi from patients with pharmacoresistant mesial temporal lobe epilepsy (MTLE) were evaluated for expression of MT-I/II and for neuronal, astroglial, and microglial populations. Compared to control cases, MTLE group displayed widespread increase in MT-I/II expression, astrogliosis and reduced neuronal population. MT-I/II levels did not correlate with any clinical variables, but patients with secondary generalized seizures (SGS) had less MT-I/II than patients without SGS. In conclusion, MT-I/II expression was increased in hippocampi from MTLE patients and our data suggest that it may be associated with different seizure spread patterns.","PeriodicalId":274261,"journal":{"name":"Journal of Epilepsy and Clinical Neurophysiology","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130520294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Added more references on mortality/death certificates, suicidal ideation and prophylaxis of preventable deaths (survey and measures). RESULTS: The studies are those: based on the Mortality Database of the Brazilian Ministry of Health; about main factors of risk for premature death in people with epilepsy; about mortality related to the epilepsy (sudden unexpected death in epilepsy - SUDEP, seizure and \"status epilepticus\", suicide, accident, surgery for epilepsy, vagal nerve stimulation and pregnancy); about unrelated mortality from the epilepsy (mainly, neoplasias, cerebrovascular disease, coronary artery disease and respiratory infection); about preventable deaths prophylaxis. CONCLUSIONS: The mortality among people with epilepsy is higher than that of the general population. The question of the increased mortality, in the postoperative period of the surgery for epilepsy, is not yet answered. The suicide occurs more often, particularly in people with refractory epilepsy and/or psychiatric comorbidities.
