Risks of Occurrence of Psychoses in Relation to the Types of Epilepsies and Epileptic Seizures

Abstract: The possible existence of the risks of occurrence of psychoses was examined in relation to the types of epilepsies and epileptic seizures. This study consisted of two investigations: 1) A study of 879 epileptic patients was conducted in which the incidence of psychoses in the different types of epilepsies was surveyed; the result was that the incidence in temporal lobe epilepsy was the highest, being relatively higher than that of other (non-temporal lobe) partial epilepsies but not significantly different from that of generalized epilepsies. 2) A comparative study was carried out on 96 patients with temporal lobe epilepsy in which 48 were psychotic and another 48 were non-psychotic which served as a control group. The differences of seizure symptomatology between the two groups were compared. The results were that the psychotic group was found to exhibit at a significantly higher rate generalized tonic-clonic convulsion and compound seizure manifestations in comparison with the non-psychotic group. The results appear to support the fact that generalizing mechanisms of temporal lobe epileptic manifestations are closely related to a physiopathogenic factor influencing psychoses.     

Localizing and lateralizing features of auras and seizures

The symptomatology of auras and seizures is a reflection of activation of specific parts of the brain by the ictal discharge, the location and extent of which represent the symptomatogenic zone. The symptomatogenic zone is presumably, though not necessarily, in close proximity to the epileptogenic zone, the area responsible for seizure generation, the complete removal or disconnection of which is necessary for seizure freedom. Knowledge about the symptomatogenic zone in focal epilepsy is acquired through careful video/EEG monitoring and behavioral correlation of seizures and electrical stimulation studies. Ictal symptomatogy provides important lateralizing and/or localizing information in the presurgical assessment of epilepsy surgery candidates. As the initial symptoms of epileptic seizures, many types of auras have highly significant localizing or lateralizing value. Similarly, motor signs during focal and secondary generalized seizures, language manifestations, and autonomic features offer reliable clues to the delineation of the epileptogenic zone. Some focal epilepsies (e.g., neocortical temporal lobe epilepsy, insular lobe epilepsy, temporal-plus epilepsies, and parieto-occipital lobe epilepsy) generate seizure manifestations that mimic temporal lobe epilepsy, potentially contributing to surgical failure. To optimize surgical outcome, careful interpretation of ictal symptomatology in conjunction with other components of the presurgical evaluation is required.     

Recent advance in epileptology]

Nowadays epilepsy is classified according to the international classification of epilepsies, epileptic syndromes and related disorders proposed by International League Against Epilepsy (ILAE, 1989). Among these epilepsies and epileptic syndromes, I detailed the clinical symptomatology and the clinical significance of benign familial neonatal convulsions, juvenile myoclonic epilepsy, epilepsy with myoclonic absence, mesial temporal lobe epilepsy and chronic progressive epilepsia partialis continua of childhood. Of 218 patients with temporal lobe resection who were followed for over 2 years, 172 patients or 79% were seizure free according to Engel's criteria of seizure outcome after surgical treatment. Of 66 patients with extra-temporal lobe epilepsy, 43 patients or 65% were seizure free. From the postsurgical outcome I talked about the need of strict presurgical evaluation to have the good postsurgical outcome. The neuropathology of surgically resected 278 specimens of temporal lobe epilepsy was mesial temporal sclerosis in 184, neuroepithelial tumors in 66, cortical malformation in 11, vascular anomaly in 13, and others in 4. Thirty-nine of resected 66 specimens of extra-temporal lobe epilepsies were cortical malformation. I presented the recent progress of genetic study in epilepsies and stressed the importance of correct diagnosis of epilepsy for genetic study.     

Autonomic phenomena of temperature regulation in temporal lobe epilepsy

Cold shiver and piloerection are rare ictal signs in focal epilepsies. They are often associated with an epileptic seizure focus within the temporal lobe. In rare cases the phenomenon of piloerection has been reported to be confined to body parts ipsilateral to the seizure focus. In this multicentric study epilepsy patients with ictal cold shiver and/or piloerection were retrospectively asked to describe exactly location and spreading patterns of these signs as well as their temporal sequence in relation to other ictal signs. Clinical data, etiology of epilepsy, and seizure focus location were also assessed. In our patient group there was a high relationship to an epileptic focus within the left temporal lobe. Distinct spreading patterns or unilateral piloerection was not indicative of a focus in the ipsilateral temporal lobe as described previously. Our results suggest that phenomena of temperature dysregulation during epileptic seizures may be of value in the presurgical evaluation as they may be indicative of a left temporal lobe seizure focus.     

Idiopathic Generalized Epilepsies Imitating Focal Epilepsies

Summary:  Classification of epileptic seizures and epilepsy syndromes as either focal or generalized is a fundamental and early part in the diagnostic process and is generally fairly easily accomplished. However, in patients with idiopathic generalized epilepsies, seizure and EEG features may suggest, particularly to the unwary, the occurrence of focal rather than generalized seizures. Misinterpretation of typical absence seizures as focal seizures, especially as temporal lobe seizures and of myoclonic seizures as focal clonic seizures, is a relatively common error and focal features during generalized tonic–clonic seizures may also be quite common. Sequences of seizures in idiopathic generalized epilepsies (such as absences or jerks followed by generalized tonic–clonic seizures) may also cause confusion. Versive and circling seizures are seizure types whose ictal semiology is clearly focal; nevertheless such seizures are described in idiopathic generalized epilepsies accompanied by generalized EEG discharges. The occurrence of focal EEG abnormalities in certain idiopathic generalized epilepsy syndromes is common. This is best known in juvenile myoclonic epilepsy.     

Classification of epilepsies and epileptic syndromes using the 1989 International League against epilepsy classification: A hospital-based study of 1,250 patients in a developing country

The 1989 International Classification of Epilepsies and Epileptic Syndromes (ICE) of the International League Against Epilepsy was used to study the distribution of epilepsies and epileptic sundromes in 1,250 patients attending an Epilepsy Clinic in Sri Lanka. Of this largely adult population, 917 (73.4%) were classified as having localization-related epilepsy, 228 (18.2%) as having generalized epilepsy, and 104 (8.3%) as having epilepsy undetermined as to whether focal or generalized. Only one case was termed special syndromes because the definition of epilepsy excluded situation-related seizures. Of the localization-related epilepsies, the majority (82.9%) were cryptogenic and 14.5% were symptomatic. Of them, approximately one third were temporal lobe epilepsies; about half the cases could not be localized to a specific lobe of the brain. The generalized category consisted of 214 (93.9%) idiopathic and 14 (6.1%) symptomatic epilepsies. Juvenile myoclonic epilepsy (JME) was the most common idiopathic generalized epilepsy (115 cases, 50.4%). Epilepsies with specific modes of seizure precipitation accounted for 6.8% (85 cases) of the total series. All 85 cases were localization-related epilepsies; 76 had eating epilepsy (EE), and 9 had self-induced epilepsy (SIE). Although some overlap occurred between certain subcategories and specific localization of localization-related epilepsies was difficult, the 1989 ICE was relevant and applicable in a clinical setting with limited investigatory facilities.     

Intractable epilepsy and disturbed visuomotor performance

The factors relevant to intractability, types of epilepsy and impairment of dexterity in patients with intractable epilepsy were studied independently in different groups of patients. The factors relevant to intractable epilepsy that were disclosed in 202 patients, who required hospitalization more than twice, were as follows: strong seizure propensity, neuropsychiatric disorders including mental deterioration of various degrees, ataxia, personality changes and psychotic episodes, intolerance to antiepileptic drugs due to acute or chronic side effects, idiosyncrasy and internal disorders, self-induced seizure, misdiagnosis and mistreatment, and breakdown of family care of patients. The types of epilepsy in 224 patients with intractable epilepsy whose seizures were not adequately controlled and recurred on a monthly basis in spite of hospitalization were classified as follows: 101 patients with localization-related epilepsies or syndromes, 106 with generalized epilepsies or syndromes, 16 with undetermined epilepsies or syndromes and one with specific syndrome. In regard to partial epilepsies, frontal lobe epilepsy and partial epilepsy with multiple foci were at least partially intractable as temporal lobe epilepsy. With respect to intractable generalized epilepsies, miscellaneous symptomatic generalized epilepsies like intractable grand mal epilepsy with progressive mental retardation in childhood were as important as Lennox-Gastaut or West syndrome though it defies classification into any established syndromes. The proposed International Classification of Epileptic Syndromes and Epilepsies was found adequate for analysis of intractable epilepsy. The disturbance of fine motor performance found in 84 patients who participated in occupational therapy was investigated by test programs comprising nine subbatteries.(ABSTRACT TRUNCATED AT 250 WORDS)

Genetics of Epilepsy and Relevance to Current Practice

Genetic factors are likely to play a major role in many epileptic conditions, spanning from classical idiopathic (genetic) generalized epilepsies to epileptic encephalopathies and focal epilepsies. In this review we describe the genetic advances in progressive myoclonus epilepsies, which are strictly monogenic disorders, genetic generalized epilepsies, mostly exhibiting complex genetic inheritance, and SCN1A-related phenotypes, namely genetic generalized epilepsy with febrile seizure plus and Dravet syndrome. Particular attention is devoted to a form of familial focal epilepsies, autosomal-dominant lateral temporal epilepsy, which is a model of non-ion genetic epilepsies. This condition is associated with mutations of the LGI1 gene, whose protein is secreted from the neurons and exerts its action on a number of targets, influencing cortical development and neuronal maturation.     

Depression and schizophrenia in epilepsy: social and biological risk factors

BACKGROUND: In a retrospective study we investigated the role of social and biological risk factors for the development of major depression and schizophreniform psychoses in epilepsy. We tested the hypotheses that social risk factors are associated with depression and biological risk factors are associated with schizophreniform psychoses. METHOD: We studied 25 patients with epilepsy and paranoid-hallucinatory psychosis, 25 patients with epilepsy and major depression, and 50 non-psychiatric epilepsy patients (controls) with respect to biological and psychosocial variables. RESULTS: Schizophrenic patients had an earlier age of onset of epilepsy and a more severe epilepsy as characterised by history of status epilepticus, multiple seizure types and severity of seizures compared to non-psychiatric controls. Simple seizure symptoms were often vegetative and EEGs showed various abnormalities including temporal lobe discharges but no lateralisation to either side. With respect to antiepileptic drugs (AED) there were only few significant differences between groups: Polytherapy as well as treatment with phenytoin (DPH) was more frequent in psychotic patients as compared to non-psychiatric patients. Patients with psychoses were also characterized by a disturbed familial background, lack of interpersonal relationships, social dependency and professional failure. Depressive patients were significantly older than non-psychiatric controls and they suffered more frequently from focal epilepsies arising from the temporal lobe. They did not differ from controls with respect to severity of epilepsy. Treatment with valproate (VPA) was inversely linked with depression, suggesting that VPA may have prophylactic antidepressive properties in epilepsy patients. There were no psychosocial variables significantly linked with depression. CONCLUSIONS: In this study, patients with different forms of psychiatric complications in epilepsy could clearly be distinguished from controls. However, we could not confirm the simple hypothesis that there are biological predictors for schizophreniform psychoses and psychosocial predictors for major depression. Neurological and sociological variables seem linked with both, suggesting a multifactorial etiology.     

伴海马硬化的颞叶癫痫患者的临床特点及手术治疗

目的探讨颞叶癫痫海马硬化的临床特点及手术治疗的效果。方法伴海马硬化的颞叶癫痫患者18例,其中男10例,女8例;年龄12~37岁,病程3~10年。癫痫复杂部分性发作10例,部分性发作继发全身性发作2例,全身强直-痉挛性发作6例。结合患者的临床表现、MRI检查和视频脑电图(V-EEG)监测结果,对这18例患者行前颞叶切除术(包括大部分海马和杏仁核)。结果所有患者术中皮层和深部电极脑电图均发现颞叶皮层海马、杏仁核有异常放电,术后病理检查均证实海马硬化的诊断。术后18例患者均出现发热,但经过抗炎、腰椎穿刺及支持治疗后渐好转。术后1年以上的随访发现16例癫痫发作完全消失,2例术后较术前显著改善,仅偶有癫痫发作,但均长期服用抗癫痫药物。结论对于颞叶癫痫伴有海马硬化的患者,如果同时脑电图又发现有同侧颞叶痫样放电,则可以考虑行该侧前颞叶切除术(包括大部分海马和杏仁核),若手术切除彻底,其术后疗效也较满意。
