We reviewed retrospectively a series of 100 inpatients with onset of epileptic seizure after the age of 60. All of them were investigated by EEG and 96 by CT scan. The most frequent cause of seizure was previous stroke, with 25 cerebral infarcts and 5 hemorrhages. Neoplastic lesions were present in 18 cases, with glioma (high grade), meningioma and metastases in the same proportion. Other etiologies included toxico-metabolic (18 cases), post-traumatic (9 cases), cerebral atrophy (4 cases) and miscellaneous (14 cases). The causes of seizure remained unknown in 7 patients, of whom 6 had focal signs in either clinical examination or EEG. Focal seizures (with or without secondary generalization) accounted for 65% of all cases and generalized seizures for 35%. The EEG was normal in 12 patients and abnormal in 88, with diffuse slowing in 55 patients and focal signs in 70 (some patients had both diffuse slowing and focal signs). Fourteen patients presented status epilepticus. Ten died during hospitalization. We conclude that epileptic seizure with onset after age 60 is nearly always symptomatic, and neuroradiologic investigations are necessary in the search for cerebral lesions. In our study, the prevalence of "idiopathic epilepsy" is lower than previously described.

Postictal aphasia has been described in left temporal lobe seizures. It may be of fluent, non-fluent or global type. We present here a patient who displayed signs of mixed transcortical aphasia (MTCA). The patient was a 67 year old man who underwent excision of a left frontal parasagittal meningioma in 1987. Since then he has been treated with phenytoin for generalized tonic-clonic seizures (GTCS). He was admitted in status epilepticus. On awakening, the patient was non-fluent with palilalia and echolalia. His repetition was relatively preserved but all the other language functions were impaired. This picture faded away within a few hours. Brain CT, performed during this postictal state, was normal except for signs related to frontal craniotomy. SPECT, which was performed after language functions returned to normal, displayed left frontal, cingular and insular hypoperfusion. The postictal language dysfunction of the patient corresponded to MTCA. Although our case has frontal, he had no other structural lesion that could explain either diffuse ischemia of the left hemisphere or watershed areas secondary to the generalized seizures. The uniqueness of this case is the combination of postictal MTCA with good prognosis.

A 12 year-old girl was treated with prophylatic cranial irradiation for acute lymphoblastic leukaemia (ALL). At the age of 39, she was admitted to our hospital for status epilepticus. Computed tomography demonstrated two, enhancing bilateral sided intracranial tumors. After surgery, this patient presented meningiomas which histologically, were of the meningothelial type. The high cure rate in childhood ALL, attributable to aggressive chemotherapy and prophylatic cranial irradiation, is capable of inducing secondary brain tumor. Twelve cases of high-dose radiation-induced meningioma following ALL are also reviewed.

The purpose of this study was to analyse retrospectively a feline population with intracranial neoplastic diseases, to document seizure patterns in these animals and to determine whether partial seizures were more frequently associated with structural brain lesions then generalised seizures. In addition, a comparison was made within the population with intracranial neoplasia between two groups of cats: one with and one without seizures. Special emphasis was given to the evaluation of tumour type, localisation and size of the lesion and its correlation with seizure prevalence. Sixty-one cats with histopathological diagnosis of intracranial tumour were identified. Fourteen cats (23%; group A) had a history of seizure(s). Forty-seven cats (77%; group B) had no history of seizure(s). Generalised tonic-clonic seizures were seen in eight cats (57%) and were the most common seizure pattern in our cats with intracranial neoplasia. Clusters of seizures were observed in six cats. Status epilepticus was observed in one patient. The mean age of the cats was 7.9 years within group A (median 8.5) and 9.3 years (median 10) within group B. The cats with lymphoma within both groups were significantly younger than cats with meningioma. In both groups meningioma and lymphoma were confirmed to be the most frequent tumour type, followed by glial cell tumours. The prevalence of the seizures in patients with glial cell tumours was 26.7%, 26.3% in patients with lymphomas and 15% in cases with meningiomas. In 33 cases (54.1%) the tumours were localised in the forebrain, 15 tumours (24.6%) were in the brainstem, four (6.6%) in the cerebellum and nine tumours (14.7%) had multifocal localisation. Parietal lobe and basal ganglia mostly affected group A. In group B tumours were most frequently located in the parietal and frontal lobes as well as in the diencephalon. A positive association was documented between the localisation of a tumour in the forebrain and seizure occurrence.

A 43-year-old male presenting with headache and dizziness underwent craniotomy and gross total resection of an extraaxial tumor was achieved via left occipital interhemispheric approach. The tumor was diagnosed as papillary meningioma arising from the left falcotentorium with such pathologic characteristics of bronchoalveolar adenocarcinoma. At postoperative day 40, he developed generalized tonic clonic seizure and then progressed to a status epilepticus pattern. Brain magnetic resonance imaging showed irregular leptomeningeal enhancement with a significant peritumoral area. Through a cerebrospinal fluid (CSF) study, we identified the meningioma cells of the papillary type from the CSF. At the postoperative day 60, he fell into semicomatose state, and the computed tomography imaging showed low density on both cerebral hemispheres, except the basal ganglia and cerebellum, with overall brain swelling and an increased intracranial pressure. He died on the following day. We experienced a rare case of a papillary meningioma with leptomeningeal seeding.

The presence of cerebral palsy and that of slow growing brain tumors are risk factors for convulsive and nonconvulsive status epilepticus. Nonconvulsive status epilepticus (NCSE) needs electroencephalographic (EEG) monitoring to be confirmed as it may be clinically subtle. Furthermore, it may present with a variety of ictal EEG morphologies. We report a case of a patient with cerebral palsy and a large central meningioma. Electroencephalogram showed a slow pattern of periodic lateralized epileptiform discharges (PLEDs) (a pattern considered as being situated in the ictal-interictal continuum) on an alpha background. The patient was treated for NCSE successfully with benzodiazepines followed by up-titration of his antiepileptic drug doses.

Epilepsy is a heterogeneous clinical condition characterized by recurrent unprovoked seizures, their causes and complications. The incidence, prevalence and mortality of epilepsy vary with age, place and time contributing to a variable extent to the burden of the disease. Diagnostic misclassification may have strong impact on personal and societal reflections of the disease in light of its clinical manifestations and the need for chronic treatment. Epilepsy accounts for a significant proportion of the world's disease burden ranking fourth after tension-type headache, migraine and Alzheimer disease. Among neurological diseases, it accounts for the highest disability-adjusted life year rates both in men and in women. Although epilepsy is self-remitting in up to 50% of cases, variable long-term prognostic patterns can be identified based on the response to the available treatments. Epilepsy carries an overall increased risk of premature mortality with variable estimates across countries. Premature mortality predominates in patients aged less than 50 years, with epilepsies due to structural/metabolic conditions, with generalized tonic-clonic seizures, and seizures not remitting under treatment. Among deaths directly attributable to epilepsy or seizures, included are sudden unexpected death in epilepsy (SUDEP), status epilepticus, accidents, drowning, unintentional injuries, and suicide. Somatic and psychiatric disorders prevail in patients with epilepsy than in people without epilepsy. Asthma, migraine and cerebral tumors tend to occur more frequently in younger adults while cardiovascular disorders, stroke, dementia and meningioma predominate in the elderly. As being a fairly common clinical condition affecting all ages and requiring long-term (sometimes lifelong) treatment, epilepsy carries high health care costs for the society. Direct costs peak in the first year after diagnosis and then vary according to the severity of the disease, the response to treatment, and the presence of comorbidity. Although in several countries the costs of epilepsy are met by the national health systems, out-of-pocket costs may be a relevant fraction of the overall costs, especially in countries where the public management of health care is suboptimal or non-existent. Epilepsy strongly affects patients' independence, psychological health and emotional adjustment. Epilepsy impairs all aspects of health-related quality of life. Awareness and attitudes of the public about epilepsy may significantly affect the burden of the disease. All these factors add to the burden of the disease. However, many of the factors implicated in the onset of epilepsy, its course and treatment can be favorably addressed with appropriate strategic plans. More research is needed to investigate and manage the medical and psychosocial implications of epilepsy.

Status epilepticus during the post-operative period is a rare complication for neurosurgery patients. Acute encephalopathic syndromes can present a diagnostic challenge due to the wide range of possible etiologies, and can also have vastly different outcomes. Posterior reversible encephalopathy syndrome is a rare neurological disorder, usually associated with specific medical conditions, that causes a disturbance of CNS homeostasis, while cortical laminar necrosis (CLN) is an unusual type of infarction characterized by selective necrosis of the cerebral cortex with sparing of the white matter. We present a 45-year-old woman who was operated on for left frontal lesion with radiological features compatible with anterior falx meningioma. Postoperative clinical and electroencephalographic data were compatible with non-convulsive status epilepticus originating from the occipito-mesial area. MRI showed bilateral diffuse temporo-occipital abnormally bright cortex as a consequence of neuronal apoptosis compatible with laminar cortical necrosis, and clinical examination revealed persistent cortical blindness. The pathogenesis of encephalopathic syndromes is still unclear. Non-convulsive status epilepticus should be considered as a possible cause of late recovery of consciousness in neurosurgery patients. Delayed treatment may cause irreversible lesions, including in brain areas far from the surgical field.
