Most seizures during pregnancy occur in women who already have epilepsy. During pregnancy most women will continue their previous level of seizure control, although 15-30% may experience an increase in seizures. Pregnancy-induced changes in antiepileptic drug pharmacokinetics are a major factor affecting changes in seizure control during pregnancy, although compliance is also a significant factor. Status epilepticus occurs in only 1-2% of pregnancies, and if treated appropriately and aggressively carries a fairly low risk of morbidity and mortality. Structural and metabolic changes may precipitate new-onset seizures during pregnancy. The structural causes include intracranial hemorrhage of multiple types, cerebral venous sinus thrombosis, and ischemic stroke. Metabolic causes include hyperemesis gravidarum; acute hepatitis (due to fatty liver of pregnancy or viral hepatitis); metabolic diseases, such as acute intermittent porphyria; infections, such as malaria; and eclampsia.

Rarely in the history of medicine has an X-linked mental retardation syndrome so thoroughly entered every branch of medicine, at least of pediatrics, but also of internal medicine, on account of its protean manifestations. In such countries as Zambia, malaria, tuberculosis, HIV, and other infections diseases, and many environmental and nutritional disorders still top the list of childhood morbidity and mortality. However, in the more developed nations of the Old and New Worlds, prematurity, birth defects, and genetic conditions constitute the major burden of infant mortality adn chronic childhood handicaps. One of the most pervasive of these is the group of FG syndromes seen in every pediatric clinic and mental health service. Thus, in our experience FGS emerges as the most common yet the least known developmental disabilities condition in our society. FGS imposes a tremendous burden of morbidity, and to some extent also of mortality, on society and families. After successful neonatal adaptation, such recurring problems as otitis, reactive airway disease, and constipation can be routinely treated symptomatically. However, the neurodevelopmental burden represents the greatest challenge that FGS presents for families and to society. Under the best of circumstances, motor and speech development catch up. However, virtually all FGS children, boys and girls, have difficulties in psychologic development, school performance, and ultimate emotional adaptation to adult life and social integration. The many such cases added to those with outright psychiatric disturbances are overwhelming social, psychologic, and psychiatric services and, above all, public and private school systems, which are understaffed, under-funded, beyond formulating individual educational plans, and helpless to deal with the enormous burden of special service needs of these children. It's time that handicapped children receive care according to needs and not according to diagnosis. However, the near absence of information on FGS available to these professionals is a handicap in arriving at a specific diagnosis (allowing state and federal support for special services) and in understanding the prognosis, natural history, and such complications as "autism," seizures, and tethered cord that affect the child's success at home, in school, and out in society. The FGS parent support group has been of enormous help in informing families about all of these "issues," and to this day remains the greatest repository of knowledge on FGS. As they say in baseball, it is time at long last for the professionals "to step up to the plate."

The neurologic symptoms in malaria are usually associated with a severe infection by Plasmodium falciparum. Less frequently, the presence of impaired consciousness, seizures and visual and auditory deficits is related with hypoglycemia (by malaria or quinine) or with the toxicity of anti-malarial drugs. In the last years, it was recognized a rare neurologic complication after the efficient treatment of Plasmodium falciparum malaria - post-malaria neurologic syndrome (PMNS). PMNS occurs days to weeks after the parasite clearance, presenting as an encephalopathy of variable severity. The pathogenic mechanisms involved in PMNS are not well understood, being admitted a possible immunological cause. We describe a case of a 61-year-old man presenting with a severe encephalopathy (delirium, cerebellar ataxia and ophthalmoparesis ), 2 days after complete recovery from Plasmodium falciparum malaria. Peripheral blood smears were repeatedly negative for malaria parasites. MRI during acute phase showed extensive multifocal white matter abnormalities. He was treated with high-dose methylprednisolone with complete resolution of neurological deficits. After 9 months the MRI showed minimal residual lesions.

Dyke-Davidoff-Masson syndrome is a disorder involving hemiatrophy or hypoplasia of 1 cerebral hemisphere secondary to an insult in the developing brain. Often this will manifest with seizures, hemiparesis, mental retardation, and facial changes. Associated with this pathology are the radiologically evident changes, such as thickening of the calvarium, hyperpneumatization of the sinuses, and dilation of the ipsilateral lateral ventricle among others. The following is a case presentation of an 18-year-old female emigrating from Ghana who presented to the emergency department with complaints of seizures diagnosed as being caused by cerebral malaria at 13 years of age. We hypothesize that the cerebral malaria and related vascular occlusion are the causes of her acquired cerebral changes. Included are computed tomography images.

Malaria is a major public health problem in the developing world owing to its high rates of morbidity and mortality. Of all the malarial parasites that infect humans, Plasmodium falciparum is most commonly associated with neurological complications, which manifest as agitation, psychosis, seizures, impaired consciousness and coma (cerebral malaria). Cerebral malaria is the most severe neurological complication; the condition is associated with mortality of 15-20%, and a substantial proportion of individuals with this condition develop neurocognitive sequelae. In this Review, we describe the various neurological complications encountered in malaria, discuss the underlying pathogenesis, and outline current management strategies for these complications. Furthermore, we discuss the role of adjunctive therapies in improving outcome.

Two cases of a one and 4 year old child of plasmodium vivax malaria are reported in association with CNS complications. Both presented with encephalopathy and seizures. One had severe thrombocytopenia, massive intracranial bleed and hydrocephalus requiring shunt surgery while the other had gastrointestinal manifestations, encephalopathy and hydrocephalus. Both responded to quinine but are left with sequelae.

The etiology of epilepsy still represents an open subject of discussions and research. Contrary to the majority of diseases for which drugs are developed following the origin of disease, epilepsy is treated symptomatically because it is perceived to have diverse causes. Recent results of oncological, neurological, developmental and biochemical studies suggest that the reproductive dysfunction in men and women, as a side effect related with antiepileptic therapy, points to the single origin of this disease. It seems that contrary to the present definition of estrogen as a compound affecting seizure susceptibility, based on causal chains: of increased estrogen levels (alcohol intake) and seizure, fact that all antiepileptic drugs are aromatase inhibitors or have estrogen binding properties, described cases of seizures in epileptic patients taking quinine as preventive therapy against malaria, impact of photic activation and sleep on estrogen level, it can be assumed that estrogen plays the leading role in the mutual origin of different types of epilepsy.

Root bark of Nauclea latifolia Smith (Rubiaceae) was evaluated for its anticonvulsant, anxiolytic, and sedative activity in mice. Animal models (maximal electroshock-, pentylenetetrazol-, and strychnine-induced convulsions; N-methyl-D-aspartate-induced turning behavior; elevated plus maze; stress-induced hyperthermia; open field; and diazepam-induced sleep) were used. The decoction from the bark of the roots of N. latifolia strongly increased the total sleep time induced by diazepam. It also protected mice against maximal electroshock-, pentylenetetrazol-, and strychnine-induced seizures. In addition, turning behavior induced by N-methyl-D-aspartate was inhibited. N. latifolia antagonized, in a dose-dependent manner, stress-induced hyperthermia and reduced body temperature. In the elevated plus maze, N. latifolia increased the number of entries into, percentage of entries into, and percentage of time in open arms, and reduced rearing, head dipping, and percentage of time in closed arms. In the open field test, N. latifolia increased crossing and reduced rearing and defecation. It could be concluded that the decoction of N. latifolia, used in traditional medicine in Cameroon in the treatment of fever, malaria, insomnia, anxiety and epilepsy seemed to possess, sedative, anticonvulsant, anxiolytic and antipyretic properties in mice.

Cerebral malaria is a severe multifactorial condition associated with the interaction of high numbers of infected erythrocytes to human brain endothelium without invasion into the brain. The result is coma and seizures with death in more than 20% of cases. Because the brain endothelium is at the interface of these processes, we investigated the global gene responses of human brain endothelium after the interaction with Plasmodium falciparum-infected erythrocytes with either high- or low-binding phenotypes. The most significantly up-regulated transcripts were found in gene ontology groups comprising the immune response, apoptosis and antiapoptosis, inflammatory response, cell-cell signaling, and signal transduction and nuclear factor kappaB (NF-kappaB) activation cascade. The proinflammatory NF-kappaB pathway was central to the regulation of the P falciparum-modulated endothelium transcriptome. The proinflammatory molecules, for example, CCL20, CXCL1, CXCL2, IL-6, and IL-8, were increased more than 100-fold, suggesting an important role of blood-brain barrier (BBB) endothelium in the innate defense during P falciparum-infected erythrocyte (Pf-IRBC) sequestration. However, some of these diffusible molecules could have reversible effects on brain tissue and thus on neurologic function. The inflammatory pathways were validated by direct measurement of proteins in brain endothelial supernatants. This study delineates the strong inflammatory component of human brain endothelium contributing to cerebral malaria.

Cerebral malaria is a diffuse encephalopathy associated with seizures and status epilepticus which can occur in up to one-third of patients with severe malaria, particularly that caused by Plasmodium falciparum. In this article, we report three cases of Plasmodium vivax malaria (all adult male patients) complicated by seizures and symptoms of diffuse meningoencephalitis. Two patients had predominantly meningeal signs, while in the third patient the features were purely of encephalitis All cases were treated with artesunate. Usually, cerebral malaria is caused by P. falciparum, and rarely, cerebral malaria is a presenting complication or occurs during the course of P. vivax infection.
