They include tyrosine hydroxylase (TH) deficiency, aromatic L-amino acid decarboxylase (AADC) deficiency, succinic semialdehyde dehydrogenase (SSADH) deficiency, gua-nosine triphosphate cyclohydrolase I deficiency, sepiapterin reductase (SR) deficiency and cerebral folate deficiency. Of these, monoamine biosynthesis and metabolism disorders are one group of inherited disorders usually requiring specific diagnostic procedures. Children with disorders of neurotransmitters often present with psychomotor retardation, hypotonia and microcephaly. Although seizures may be more common in patients with SR deficiency, patients with TH or AADC deficiency only occasionally have non-epileptic myoclonus. However, the episodic dystonia and oculogyric crisis manifested in these patients are frequently misdiagnosed as epilepsy, and multiple anti-epileptic drugs (AEDs) may be given. In the present short review, the pathogenesis and diagnosis of these neurotransmitter disorders are discussed, with the hope that correct diagnosis of pediatric neurotransmitter diseases can reduce the unnecessary AED treatment.","PeriodicalId":39430,"journal":{"name":"Epilepsy and Seizure","volume":"3 1","pages":"147-153"},"PeriodicalIF":0.0,"publicationDate":"2010-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70082213","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}

Noebels","doi":"10.3805/EANDS.3.72","DOIUrl":"https://doi.org/10.3805/EANDS.3.72","url":null,"abstract":"The number of genes underlying monogenic epilepsies in human and animal models continues to grow as the clinical syndromes for a variety of heritable epilepsies yield to neurogenetic analysis. Interestingly, the diversity of co-morbid phenotypes linked to single epilepsy gene defects is also expanding. While many rare familial idiopathic epilepsy disorders are typically defined as \"pure\" seizure syndromes, many occur in the context of more complex clinical symptomatology. This is not surprising, since genes that alter cortical excitability are expressed in diverse brain networks, as well as in other tissues. In this brief review, two such genes are described. The gene encoding amyloid precursor protein along with related genes contributing to the accumulation of an aberrant peptide cleavage product, Aβ42, has now been placed in a molecular pathway mediating both the dementia of Alzheimer's Disease and seizures. A second gene, KCNQ1, encoding one of the voltage-sensitive ion channels contributing to membrane repolarisation in the heart, is co-expressed in both heart and brain where mutations contribute to cardiac arrhythmias, early mortality, and seizures. KCNQ1, a member of the cardiac LQTS gene family, is the first validated candidate gene for sudden unexplained death in epilepsy (SUDEP). The new strategy of searching for epilepsy genes linked to non-epileptic co-morbidity is providing illuminating examples of the role of neuronal network hyperexcitability in explaining the clinical spectrum of complex human neurological disorders that feature seizures.","PeriodicalId":39430,"journal":{"name":"Epilepsy and Seizure","volume":"3 1","pages":"72-83"},"PeriodicalIF":0.0,"publicationDate":"2010-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.3805/EANDS.3.72","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70082656","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}

No abnormalities were evident in a physical examination but his cognitive function was impaired. Thus panic disorder or non-specific dementia with psychosis was initially suspected. Brain MRI was almost normal, except for an old right basal ganglia infarction and mild frontal atrophy. Neuroimaging studies showed reduced glucose metabolism over bilateral frontal, right temporal and right parietal regions. When a panic-like attack occurred, EEG documented ictal discharges in the right frontal and temporal areas. After successful treatment with carbamazepine, cognitive dysfunction and abnormal findings on brain imaging were improved. This case suggests that epilepsy should be suspected in a patients presenting with anxiety symptoms of panic-like attacks and hallucinations.","PeriodicalId":39430,"journal":{"name":"Epilepsy and Seizure","volume":"2 1","pages":"28-33"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70082109","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}

Intraoperative electrocorticography demonstrated frequent paroxysmal activities on the yellowish cortex above the CM. Anterior frontal lobectomy including the irritative cortex, CM, MVM and its tributaries was performed. The patient became seizure free after surgery. Pathologically, the irritative cortex above the CM had hemosiderin deposits and astrogliosis. The CM was surrounded by dilated veins of various sizes, indicating MVM, which confirmed the radiological findings of so-called caput medusae. Epileptogenicity in patients with CM and MVM is thought to be due to repeated hemorrhage from the CM.
