PURPOSE: To determine the incidence of psychiatric disorders before and after surgical treatment for partial epilepsy and to document the effectiveness of their treatment. METHODS: Fifty consecutive patients treated surgically for focal epilepsy (44 temporal and six frontal) were evaluated by established neuropsychiatric methods before surgery and over a mean period of 2 years after surgery. The patients with interictal dysphoric disorders, with or without psychotic episodes, were treated with tricyclic antidepressant medication alone or combined with serotonin selective reuptake inhibitors and, if necessary, with the addition of risperidone. RESULTS: Before surgery, 25 (57%) of the 44 patients with temporal lobe epilepsy had dysphoric disorders. After surgery, 17 (39%) of the 44 patients experienced either de novo psychiatric complications (six psychotic episodes, six dysphoric disorders, and two depressive episodes) or exacerbation of preoperative dysphoric disorder (three patients). Eight previously intact patients of the 19 (42%) developed dysphoric disorders after surgery that were significantly related to recurrence of seizures. All psychiatric complications occurred in the first 2 months after surgery, except for the six patients intact before surgery, who had a recurrence of seizures. A significant predictor of ultimate excellent psychiatric outcome was complete absence of seizures after surgery. All postoperative psychiatric complications remitted on treatment with psychotropic medication in the compliant patients. CONCLUSIONS: An exceptional psychiatric morbidity is associated with the months after temporal lobectomy. Possible pathogenetic mechanisms are discussed. Antidepressant drugs are very effective in treating the psychiatric disorders of chronic epilepsy; their use in conjunction with the surgical treatment of epilepsy appears to be crucial for the overall positive outcome of a significant number of patients. 相似文献

In the course of an open study on the add-on treatment of tiagabine (TGB) in patients with localization-related epilepsy syndromes, 2 of 9 patients developed nonconvulsive status epilepticus (NCSE) with electroclinical features consistent with those of atypical absence seizures. One patient had never had atypical absence seizures before. In both cases, immediate discontinuation of TGB was followed by complete and sustained electroclinical remission; we suggest a possible causative role of TGB. This observation may be consistent with a paradoxical effect of TGB in selected cases. Possible risk factors and a pathophysiological hypothesis are discussed. 相似文献

INTRODUCTION AND MATERIAL: During 54 months, we have studied the electro-clinical and neuroimaging features in outpatients with active epilepsy. Each patient was interviewed for one of us. Then, we have reviewed the medical records about both the clinical featuring. EEG and neuroimaging (NI) studies and seizures frequency (SF) outcome. Differences in crude proportions were assessed by chi 2 test for independence by 2 x 2 tables. RESULTS AND CONCLUSIONS: It has been 207 patients with 49 +/- 19.6 years of mean age at review. Partial seizures was significantly related with both a higher SF at onset and politherapy. Also, with a focal EEG distribution but only in case of complex partial seizures. Abnormal NI was significantly more frequent in oldest patients. A greater proportion of patients were in politherapy in four situation: SF at onset > 1 by day, a focal EEG distribution, duration of epilepsy longer than 20 years and age of onset lesser than 60 years. A 37.2% was seizures-free in the last year and in 34% the SF was improved a 50% or more from the beginning. A significantly greater proportion of patients was following with seizures in four cases: when the SF at onset has been > or = 1 by day, being partial seizures, women and having politherapy. 相似文献

We tapered antiepileptic drugs in 40 patients with epilepsy due to neurocysticercosis who had been free of seizures for 2 years. All patients previously received a course of albendazole that resulted in complete destruction of brain cysts. We followed the patients prospectively from the time of diagnosis until 12 months after antiepileptic drug withdrawal. We evaluated the following prognostic factors for seizure recurrence: sex, number of seizures before control, type of seizures, number of parenchymal brain cysts before albendazole therapy, EEG findings, and CT findings after albendazole therapy. In the univariate analysis of prognostic factors for seizure recurrence, the development of brain calcifications caused by albendazole was the only factor associated with a significantly higher rate of relapse (p = 0.004). The multivariate analysis showed that patients who had both recurrent seizures and multiple brain cysts also had a higher risk of relapse than those with single seizures or single cysts (p = 0.05). This study suggests that the prognosis of epilepsy due to neurocysticercosis is not as benign as previously thought. Patients with residual calcifications and those with both recurrent seizures and multiple cysts before albendazole therapy have the highest rate of relapse after withdrawal of antiepileptic drugs. 相似文献

Studies dating back more than 150 years reported a relationship between hippocampal sclerosis and epilepsy. Retrospective studies of patients who underwent temporal lobectomy for intractable partial epilepsy found a relationship between a history of early childhood convulsions, hippocampal sclerosis, and the development of temporal lobe epilepsy. Many believe that febrile seizures lead to hippocampal damage and this in turn predisposes the patient to the development of temporal lobe epilepsy. Studies in adult rats have shown that seizures can lead to hippocampal damage and unprovoked recurrent seizures. However, many questions remain as to the relevance of early childhood seizures to hippocampal sclerosis and temporal lobe epilepsy. Human prospective epidemiologic studies have not shown a relationship between early childhood seizures and temporal lobe epilepsy. Recent MRI studies in humans suggest that a preexisting hippocampal lesion may predispose infants to experience febrile seizures, later on hippocampal sclerosis, and possibly temporal lobe epilepsy may occur. Unlike the studies in adult rats, normal immature rats with seizures have not been shown to develop hippocampal damage or unprovoked seizures in adulthood. Furthermore, animal studies reveal that preexisting brain abnormalities can predispose to hippocampal damage following seizures early in life. This paper reviews evidence for and against the view that early childhood convulsions, hippocampal sclerosis, and temporal lobe epilepsy are related, while also exploring clinical and animal studies on how seizures can lead to hippocampal damage, and how this can result in temporal lobe epilepsy. By better understanding the cause and effect relationship between early childhood seizures and hippocampal injury in normal and abnormal brains specific treatments can be developed that target the pathogenesis of epilepsy. 相似文献

Seventeen patients with cortical dysplasia who had surgical resection for medically intractable partial epilepsy were studied. Compared with two groups of surgically treated patients with intractable epilepsy due to tumour (n = 20) and mesial temporal sclerosis (n = 40), patients with cortical dysplasia showed significantly more frequent extratemporal lesions, more frequent non-epileptiform EEG abnormalities and less favourable surgical outcome for seizure control. Patients with cortical dysplasia were younger at onset of seizures and had a lower detection rate of CT abnormalities compared with the tumour group, and lower IQ compared with the mesial temporal sclerosis group. MRI was abnormal in five of seven patients. Six patients became seizure-free or almost seizure-free but eight did not experience relief of seizures. Surgical outcome related to the extent of pathology but not to the histological abnormality. Lesions outside the temporal and frontal lobes were correlated with poor surgical outcome, as were generalised interictal EEG abnormalities, which may reflect extensive or multiple lesions. Ictal intracranial recordings were not useful for presurgical evaluation of cortical dysplasia. 相似文献

We determined how noninvasive presurgical data relate to prognosis after temporal lobectomy in patients with independent bilateral temporal lobe (IBTL) complex partial seizures on the intracranial electroencephalogram (EEG). Between 1986 and 1994, 28 patients had IBTL seizures on intracranial EEG. Fifteen of these 28 patients underwent temporal lobectomy and 13 were not offered surgery. Of the 15 patients who had surgery, 10 patients became seizure-free. Magnetic resonance imaging (MRI) and the Wada test were the only variables associated with a seizure-free outcome. Seven of 10 seizure-free patients had a lateralized Wada result or the presence of unilateral hippocampal sclerosis, whereas none of the patients with persistent seizures had either of these findings. Variables not found to be predictive of a seizure-free outcome included location of scalp interictal spikes, degree of seizure-onset laterality, presence of early epilepsy risk factor, duration of epilepsy, and full-scale intelligence quotient. We conclude that MRI and the Wada test provide information of prognostic value in patients with bilateral temporal seizures independent of intracranial EEG data. 相似文献

Partial seizures and asymmetric abnormalities seen on electroencephalogram (EEG) are infrequent in juvenile myoclonic epilepsy, but when present, can lead to a misdiagnosis of partial seizures. We report four patients with juvenile myoclonic epilepsy who had generalized spike or polyspike and wave discharges on EEG in addition to clinical and EEG evidence of focality. The clinical course and response to therapy was similar to that in typical juvenile myoclonic epilepsy. 相似文献

Although epilepsy is commonly associated with shunt-treated hydrocephalus, its relation to the shunting procedure and the criteria identifying postoperative epilepsy remain controversial. Of 283 patients shunted at Würzburg University Hospital over a 24-year period (1970 to 1994), 182 were followed up for a minimum of 1 year after shunt insertion and entered the study. The data were analyzed retrospectively in 1995 and 1996. Epilepsy was analyzed in relation to the etiology of hydrocephalus, functional status, time and site of shunt insertion, onset of seizures and seizure type, EEG changes, sex, shunt systems, and shunt revisions. Of the 182 patients studied, 37 (20%) developed epilepsy. The incidence of epilepsy varied according to the etiology of hydrocephalus: posthemorrhagic (5%), postinfectious (4%), connatal/miscellaneous/unknown (3%), myelomeningocele (2%), tumor/arachnoidal cyst/aqueduct stenosis (0%). Early shunting and poor functional status was associated with a higher risk for epilepsy. Epilepsy was not influenced by sex, shunt systems, or number of shunt revisions. Twenty-two (12%) of 182 patients developed epilepsy (generalized N=13, focal N=9) after intracranial shunting. Focal EEG abnormalities (N=16) were located mainly at the anatomical site of the shunt (N=14), but only three patients (2%) presented with focal seizures contralateral and focal EEG abnormalities ipsilateral to the site of the shunt. The presence of epilepsy was determined by the etiology of hydrocephalus rather than by surgical intervention. The incidence of postoperative epilepsy (12%) was low. Onset of epilepsy, clinical presentation of seizures, and EEG changes did not appear to be valid criteria for identifying shunt-related epilepsy. Thus, epilepsy as a complication of intracranial shunting might be overestimated in the literature. 相似文献

This study aims to understand seizure control outcomes and the risk of developing new wake seizures (WS) related to the different types of pure sleep epilepsies (SE), which is important in making rational management plans. A retrospective review of the Yonsei Epilepsy Clinic Registry identified 63 patients with pure SE not belonging to any specific epileptic syndromes. They were divided into the group of generalized tonic-clonic seizures during sleep (S-GTCS : n = 21) and the group of partial epilepsies during sleep (S-PE: n = 42) on the basis of seizure phenomenology, EEG, and neuroimaging data. These patients were followed for 2 years and their clinical variables were analysed for seizure control outcomes and development of new WS. Of 21 patients with S-GTCS, 17 achieved a seizure-free outcome and only one patient developed a new WS, which was consistent with a partial-onset secondary GTCS in phenomenology. Of 42 patients with S-PE only 15 patients achieved a seizure-free outcome and 11 patients developed WS during the 2-year follow-up period. Higher baseline seizure frequency and longer duration of epilepsy were associated with a higher incidence of new WS. The results suggest that the patients with S-GTCS carry a favorable clinical course, thus driving privileges or freedom of daily activities can be conferred without delay once their seizures are well controlled. However, the seizure control outcome was poor and the development of WS was frequent in patients with recurrent S-PE. 相似文献

OBJECT: The incidence of epilepsy among children with hydrocephalus and its relation to shunts and their complications, raised intracranial pressure (ICP), and developmental outcome are explored in a retrospective study. METHODS: The authors studied a series of 802 children with hydrocephalus due to varying causes, who were treated by ventriculoperitoneal shunt placement between 1980 and 1990, with a mean follow-up period of 8 years. Patients who had tumoral hydrocephalus and those whose files lacked significant data were excluded. Data extracted from medical records, including history of the hydrocephalus and history of seizures, if any, were analyzed. Thirty-two percent of the children had epilepsy, the onset of which frequently occurred at approximately the same time that the diagnosis of hydrocephalus was made. The majority of the affected children had severe uncontrolled epilepsy. The incidence of epilepsy was significantly affected by the original cause of the hydrocephalus. The presence of radiological abnormalities was also found to be a significant predictor of epilepsy. Similarly, shunt complications predisposed to epilepsy. Episodes of raised ICP related to hydrocephalus or in association with shunt malfunction may also predispose to epileptic seizures. Furthermore, the presence of a shunt by itself seems able to promote an epileptogenic focus. Finally, epilepsy appears to be an important predictor of poor intellectual outcome in hydrocephalic children with shunts. CONCLUSIONS: A prospective study is needed to identify clearly and confirm avoidable factors predisposing to seizures in these children so that we can strive to reduce the incidence of these seizures and, subsequently, improve these children's quality of life. 相似文献

As a group, epilepsies of frontal lobe origin are thought to be poorly localized using surface EEG recordings. This finding may depend on the specific areas of frontal lobe from which the seizures originate or the pathologic substrate. We reviewed the presurgical surface EEGs of patients with frontal lobe epilepsy who underwent epilepsy surgery. The specific area of the frontal lobe where seizures originated was determined by 1) intracranial ictal EEG recordings, or 2) the presence of a structural lesion, identified by imaging studies in patients who achieved complete seizure control following surgery. We differentiated patients whose seizures began in the dorsolateral frontal convexity from those whose seizures began in the medial frontal region, and we correlated EEG findings in the interictal, postictal, and ictal states with seizure semiology, pathologic substrate, and surgical outcome. Four of nine patients had seizures originating in the dorsolateral frontal convexity and five had medial frontal onset seizures. Patients whose seizures originated from the dorsolateral convexity had focal interictal epileptiform abnormalities that localized to the region of seizure onset. Patients whose seizures began in the medial frontal region had either no interictal epileptiform abnormality or had multifocal epileptiform discharges. Patients whose seizures began in the dorsolateral convexity showed focal electrographic seizure activity that was localizing. This rhythmic fast activity did not appear to be substrate-specific. Patients whose seizure onset localized to the medial frontal region did not show focal electrographic seizure at clinical onset. We conclude that the scalp EEG recordings of frontal lobe epilepsies contain features that enable differentiation of seizures originating from two different regions of the frontal lobe. 相似文献

Since 1987, we have diagnosed 10 patients, 4 males and 6 females, aged 2-11 years at the last evaluation, who all met the following criteria of severe myoclonic epilepsy in infancy (SMEI): generalized or unilateral long-lasting febrile clonic seizures in the first year of life; the subsequent appearance of myoclonic seizures and other types of seizure (partial seizures, atypical absences and convulsive status epilepticus); and neuropsychological deterioration for a certain period. Family histories of epilepsy and febrile seizures could be traced in 1 and 3 cases, respectively. None of them had previous personal history of brain insult. Electroencephalographic (EEGic) recordings in febrile seizure stage were normal; and continuous prophylaxis with phenobarbital failed to prevent the recurrence of febrile seizures. EEG studies in myoclonic stage showed generalized spike-and-waves, polyspike-and-waves, focal abnormalities and/or photosensitivity. The seizures were highly resistant to antiepileptic drugs. Our experiences suggested that comedication of valproic acid, clonazepam and carbamazepine may be most effective in treatment of the diverse seizures including myoclonic seizures, myoclonic-tonic-clonic seizures, atypical absences and partial seizures. Myoclonic seizures and atypical absences diminished in parallel to a clear-cut decrease in generalized abnormalities on EEG in 4 cases aged more than 7 years. However, the partial seizures, secondarily generalized seizures and status epilepticus were still present. Further investigations should aim to identify the underlying etiology and to search more effective treatment. 相似文献

This review was conducted to evaluate the long-term prognosis of children responding to vigabatrin by examining the incidence of increased seizure frequency, loss of efficacy, and appearance of new seizures in a cohort of 196 children (mean age, 68.2 months; range, 2 months to 19 years) with drug-resistant epilepsy, who had received vigabatrin as add-on treatment in clinical trials. The results indicate that an increase in seizure frequency was uncommon, occurring in only 10% of children with highly drug-resistant epilepsy and that it usually appears shortly after the initiation of treatment. It was clearly not dose-dependent and most often occurred in patients with nonprogressive myoclonic epilepsy. No specific seizure type was specially involved and usually the problem reversed on discontinuing vigabatrin. Loss of efficacy was also uncommon (12% of patients), and again no specific seizure type was found to be associated. Epilepsy syndrome does seem to be a better predictor of loss of efficacy because it occurred most often in symptomatic generalized epilepsies and cryptogenic infantile spasms. A total of 21 patients (11%) developed genuinely new types of seizures. Fifteen of these patients developed new partial seizures that had little impact on the patients' overall clinical improvement. The new partial seizures were better tolerated than the initial seizure type which in most cases had disappeared. Approximately 3% of patients experienced new generalized seizures that aggravated their initial condition. These occurred most often in patients with nonprogressive myoclonic epilepsy; therefore vigabatrin should be used with particular caution in such patients. 相似文献

Epilepsy is one of the commonest neurological/disorders, with peak incidences among the elderly and among children in the first year of life. Approximately 60,000 (0.7 per cent) of the Swedish population, 50,000 adults and 10,000 children, have active epilepsy. Stroke is the aetiology most commonly identified. The majority of those with a first-ever unproven seizure suffer no further seizures. Of those who do have further seizures (i.e., who develop epilepsy), 65-85 per cent eventually become free from seizures, and many of them are able to cease antiepileptic medication. Epilepsy is a heterogeneous disorder. The larger proportion of patients who are otherwise healthy, and who respond readily to antiepileptic treatment and manifest no side effects or only mild ones, are characterised by the best prognosis and are able to terminate treatment within 2-5 years without recurrence. At the other extreme is the smaller group of patients with onset of epilepsy very early in life, and characterised by multiple severe neurological defects, severe daily seizures, resistance (more or less) to all available treatment, and high mortality. In many cases of epilepsy, however, severity and prognosis lie somewhere between these two extremes. 相似文献

A retrospective analysis of seizure outcome and quality of life assessment was done in 64 patients under 18 years of age with medically refractory epilepsy who underwent 64 primary and 16 repeat operative procedures in an attempt to control their epilepsy. At least 2 years' follow-up data were available for each patient. Operative procedures were 44 temporal lobe resections; 16 extratemporal resections; and 4 hemispherectomies. Effective control of previously intractable seizures was obtained in most patients: 55%, 11%, and 17% achieved Engel class I, II, and III status, respectively. Successful seizure control was thus obtained in 83%, while 17% (Engel class IV) failed to improve significantly after operation. Quality-of-life measures parallelled the improvements in seizures control, being highest in Engel I, outcome group and lowest in Engel IV outcome group. In appropriately selected pediatric and adolescent patients with medical refractory epilepsy, surgical management can offer a safe and effective adjunct to medication. 相似文献

The relations between epilepsy and heart are complex and expressed in two opposite sides. (1) Cardiac arrhythmias may provoke epileptic seizures but these seizures are, in this case, syncopal attacks. Nevertheless, in the past, these clinical features have been individualized as "cardiac epilepsy" or epilepsy in cardiacs. However, true epileptic seizures could be observed in the course of a syncopal attack and a syncope may complicate the issue of an epileptic seizure. (2) On the other hand, epileptic seizures may provoke severe cardiac arrhythmias. The incidence rate of sudden death in patients with epilepsy is estimated to be 1/1000 patients. The exact neural mechanisms in cardiac arrhythmias seizures could explain only some of the sudden unexpected deaths observed in epileptic patients. The role of antiepileptic drugs on cardiac conduction as well as the effects of seizures or status epilepticus on the myocardium are other enigmatic aspects of the relations between epilepsy and heart. 相似文献

Idiopathic generalized epilepsy (IGE) comprises several subsyndromes. These are principally: benign neonatal familial convulsions, benign neonatal convulsions, benign myoclonic epilepsy in infancy, childhood absence epilepsy, juvenile absence epilepsy, juvenile myoclonic epilepsy, epilepsy with generalised tonic-clonic seizures on awakening. In addition, there are less well-recognized syndromes, such as eyelid myoclonia with absences. The pathophysiology of the IGE syndromes is not fully understood; it is evident that typical absences are the result of abnormal oscillations between the thalamus and cerebral cortex. Genetic studies are in progress to elucidate the biochemical defects underlying the conditions. The clinical and electroencephalographic features of the individual subsyndromes are distinct, but some patients may be difficult to classify into a particular subgroup. A correct syndromic diagnosis is important, as treatment strategies differ for patients with the different forms of IGE, and it is necessary for genetic research. 相似文献

Surgical treatment of refractory epilepsy in childhood and adolescence has been shown to be effective in reducing the seizure frequency. This paper examines the question: "Does this result in a better socioeconomic outcome in later years?" Patients who underwent a surgical procedure for the treatment of their medically refractory epilepsy at our hospital, had more than 2-years' follow-up, and were less than 18 years old at time of survey were included. From a retrospective chart review, age at onset and at surgery, duration of seizures prior to surgery, years of follow-up, type of surgery, and neurological status were obtained. From a telephone survey, seizure frequency after surgery, marital, financial and driving status, level of education, and employment status were ascertained. Sixty-four patients in our epileptic surgical series meet entry criteria. Significantly higher levels of education, employment status and independence were found in patients with a class I Engel outcome compared to other Engel outcomes. 相似文献

CONCLUSION: We conclude that despite inevitable variability the clinical picture of JME is characteristic. It is easy to diagnose JME if one thinks of it while the history should be thoroughly analyzed. An EEG recording during sleep confirms the diagnosis. An early diagnosis of JME permits adequate prognosis of the subsequent course of epilepsy, and adequate therapy brings remission in most of the patients. If treatment starts following the large number of severe GTC seizures, the response to therapy is incomplete. The persistency of the illness throughout the life, the need for continuous medication and therapeutic unresponsiveness in cases with late diagnosis, do not justify the increasing misconception that JME is of benign nature. Diagnosis of JME is rare because of insufficient familiarily of physicians with the illness. BACKGROUND: Juvenile myoclonic epilepsy (JME) is an idiopathic generalized epileptic syndrome characterized with the combination of myoclonic, generalized tonic-clonic (GTC) and absence seizures that are readily provoked by sleep deprivation. PATIENTS: Forty-three patients, aged from 14 to 51 years, participated in a 5-year follow-up study. Diagnosis was made according to the criteria (Table 1) for diagnosis of JME set by Panayiotopoulos et al. (1994). Nineteen patients made their first contact with a neurologist at the Institute of Neurology and were diagnosed as JME, while the remaining 24 were referred to from other medical institutions with a diagnosis of therapy resistant to focal epilepsy. All patients underwent a somatic and neurological examination, "mini mental test," EEG in waking and CT scan of the brain. Some patients had EEG performed during sleep and some had MRI of the head. RESULTS: JME began between 9 and 26 (average 17) years. All patients had myoclonic seizures, 98% had GTC and 23% absence seizures. The first myoclonic seizure occurred between 9 and 24 years while the frst GTC seizure occurred between 10 and 32 years. Myoclonic seizures (83% of patients) and GTC seizures (70% of patients) occurred most often immediately after awaking. The most frequent provocative factors were insufficient sleep, alcohol abuse and tiredness. Epilepsy in the family was present in 39%, focal neurological deficiency in 9% and pathological findings on of CT and MRI in 7% of patients. Waking EEG was pathological in 77% of patients; it included generalized spike-wave discharges in 73%, multiple spike-wave complexes in 33% and focal discharges in 12% of patients, respectively. In all 26 patients tested, sleep EEG was pathological most often with multiple spike-wave complexes in 85% and 3-4 Hz spike-wave complexes in 57% of patients. The correct diagnosis of JME following a comprehensive examination was made in 24 (56%) patients after a delay of 1 to 35 years. In 24 patients with delayed diagnosis of JME the replacement of earlier medication with valproic acid (VPA) induced remission in 18 patients (75%) while 1 patient (4%) experienced a reduction in the number of seizures. Five patients (21%) did not respond to VPA medication: 2 due to a weak compliance, another 2 due to inefficient medication and 1 because of the preexistent malabsorption syndrome. In 19 patients (44%) with initial diagnosis of JME, VPA was introduced immediately upon diagnosis. Of them, 15 (79%) had excellent response to VPA, 1 refused therapy and for 3 patients there is no information. In 2 patients VPA was substituted due to side effects (hepatotoxicity and alopetia) with lamotrigine (low doses), which brought about decrease in frequency and mitigation in myoclonic seizures. 相似文献
