Among 630 patients with human immunodeficiency virus infection, 70 patients with new-onset seizures were studied. Generalized seizures occurred in 66 patients (94%): they occurred as the initial seizure in 56 patients (80%) and during follow-up in another 10 patients (14%). Partial seizures (18 patients), status epilepticus (10 patients), and recurrent seizures (38 patients) were also noted. Identified processes included cerebral toxoplasmosis in 11 patients, cerebral lymphoma in 8, metabolic derangement in 8, cryptococcal meningitis in 7, and vascular infarction in 4. In 32 patients (46%) seizures were not associated with identifiable brain lesions and were believed to result from human immunodeficiency virus cerebral infection. Phenytoin treatment was associated with adverse drug reactions in 16 of 62 patients who received it. Our results suggest that the majority of patients with human immunodeficiency virus and seizures do not have secondary focal brain lesions as the cause of the seizures and that human immunodeficiency virus infection alone can, and often does, cause seizures.

The occurrence of physiological cell death has been known for decades, but interest in the subject was renewed in 1972 when Kerr, Wyllie and Currie described in detail the ultrastructural changes characteristic of dying cells and coined the term apoptosis to describe the process. Cells display a wide variety of morphological changes when dying during development or following a toxic insult. A binary classification scheme suggests that physiologically appropriate death is due to apoptosis and that pathological mechanisms involve necrosis. However, recent studies indicate a potential involvement of apoptotic cell death in ischemia, status epilepticus and HIV-1 infection.

The non-convulsive status epilepticus (NCSE) is a complication of petit mal epilepsy or epilepsy with temporal lobe seizures. Very rarely it is the primary manifestation of a symptomatic epilepsy. This report is on a 30-year old female inpatient with NCSE as the primary manifestation of symptomatic epilepsy, occurring four years after HIV infection (stage B3 according to the CDC classification) through heterosexual contact. After an initial tonic-clonic seizure, the patient suffered from NCSE for four weeks with diminished consciousness and major cognitive deficits. During this whole time period the EEG showed bilateral synchrone 1-2 Hz spike-wave complexes. After several failed treatment attempts, the NCSE was successfully and permanently treated with a combination of valproic acid and ethosuximide. The cerebrospinal fluid, cranial CT and cranial MRI were completely uneventful with regard to a CNS infection by the HI-virus or other infectious agents. 20 days after the initial symptoms, MRI showed bilateral cortical-subcortical and bilateral hippocampal lesions which stood out as focal edema zones, gradually disappeared completely and occurred in combination with the development of a discrete brain and right sided hippocampal atrophy. The EEG continued to show signs of right-temporal epileptic discharges with tendencies to generalise after 3 months but normalised after 6 months. Epileptic seizures are rarely an initial clinical sign of an infection with the HI-Virus even if no signs of encephalitis is detectable in the cerebrospinal fluid or in the cerebral MRI.

Creutzfeldt-Jakob disease (CJD) is a presenile dementia characterized by rapidly progressive mental deterioration, myoclonic jerking, and other less common neurological signs. Few autoctonous cases have been described in Brazil. A 54-year-old white woman, was admitted in our service with a month history of progressive, bilateral cortical blindness. After admission, she developed right partial motor seizures( right facial, upper and lower limbs), she became progressively aphasic( mixed aphasia). Seizures were controlled with phenytoin, but she developed choreoathetotic movements on her right dimidium, with partial control after introduction of chlorpromazine 25 mg q/d. She could no longer stand up or walk due to severe ataxia. The first EEG (October, 2001) showed left hemisphere severe seizure activity (status epilepticus partialis). She was delivered home with enteral nutrition, phenytoin, chlorpromazine and mepacrine 100 mg qd. The following laboratorial tests were negative or normal: blood series, platelets, ESR, kidney and liver function, copper, ceruloplasmin, VDRL, HIV, HTLV-1, lactate, and cerebral DSA (performed in other service).A spinal tap with normal opening pressure was perform and CSF examination was normal. CSF 14-3-3 protein was positive, CSF specific neuronal enolase 7.5 ng/ml(normal). Genetic study of PRNP gene did not disclosed any known mutation. A MRI (October, 2001) showed areas of hyperintense signal (T2 and FLAIR) without Gd-enhancement on T1, in the left temporal lobe and in both occipital lobes; basal ganglia have a normal appearance. DWI imaging showed bright areas at the same sites. An EEG (March, 2002) disclosed a periodical sharp triphasic waves pattern, suggestive of CJD. A second MRI (April, 2002) showed mild generalized atrophy, no ventricular dilatation, and the hyperintense sites disappeared. She remained clinically stable and under use of chlorpromazine and mepacrine until she died due to pulmonary complications on April, 2003.

The authors reviewed the records of 42 patients with HIV infection and status epilepticus (SE). Brain tumor and infection were the most common etiologies. The median duration of SE was 2.0 +/- 10 hours. Most patients (37 [88%]) responded to IV benzodiazepine or phenytoin treatment. Nevertheless, 12 (29%) patients died and 15 (36%) developed new neurologic deficits. In patients with HIV infection, aggressive management of seizures may limit the risk of SE.

A previously healthy 32-year-old man visited our clinic with a 5-week history of involuntary movement. Examination demonstrated continuous myoclonic jerks in the left elbow. Two days later, he developed generalized convulsion. Electroencephalography demonstrated small spikes over the right central region. Thus, we made a diagnosis of epilepsia partialis continua (EPC) with a secondary generalization. On admission, serum electrolytes, glucose and ceruloplasmin levels, and amino acid analysis were unremarkable. HIV serology was negative. Anticardiolipin, anti-MPO ANCA, and anti-Hu antibodies were negative. The cerebrospinal fluid (CSF) showed 151/microl lymphocytes and 23/microl polymorphs, 70 mg/dl of glucose, and 61 mg/dl of protein. Autoantibodies against the glutamate receptor subunits epsilon-2 and delta-2 were detected in the serum and CSF. Cranial MRI was unremarkable. Treatment with acyclovir and high-dose methylprednisolone failed to halt the jerks. Two weeks after admission, he developed status epilepticus, which necessitated general anesthesia. Intravenous immunoglobulin infusion gave no beneficial effects. Two months after the onset of the status epilepticus, his convulsions were controlled with zonisamide, clobazam, and carbamazepine. While he had no motor dysfunctions, he had loss of spontaneity and memory impairment. This report suggests that EPC might be the initial symptom of subacute encephalitis with a possible autoimmune mechanism.

We describe an HIV-infected, bilingual patient presenting with Wernicke's aphasia due to partial status epilepticus with periodic lateralized epileptiform discharges, as the first sign of AIDS-toxoplasmosis complex. The localization of the native and secondary language centers in the brain and the possible role of recurrent seizures in the fluctuating course of Wernicke's aphasia in this patient are discussed. The clinical course of this patient supports the belief that a second language area for a second language learned in the later stages of life is located in an area different from that for the native language but still in close proximity to it.

Epilepsia Partialis Continua (EPC), a subtype of status epilepticus has varied etiology and the outcome depends on the cause. The aim of this study was to analyze the demographic, semiology, etiology, radiological findings, therapeutic response and outcome of EPC. This is a retrospective analysis of 76 patients (M:F: 46:30; mean age: 30.2+/-23.4 years; median age: 26 years) evaluated at our center over last 14 years. Twenty-three subjects (30.3%) had epilepsy for a mean of 25.8+/-52.3 months (range: 1-81 years; median: 14) before developing EPC and in half of them, seizures were controlled with anti-epileptic drugs (AEDs). Rest 53 (69.3%) manifested as de novo. The mean duration of EPC was 47.02+/-188.2 days (range: 1h to 48 months; median: 3 days). One patient of generalized convulsive SE (GCSE) evolved into EPC while five patients of EPC evolved into GCSE. CT scan of brain (n-76) was abnormal in 53 (69.7%) while all the 11 MRI scans which were available were abnormal. EEG (n-21) was abnormal in all but one, however it was non-specific in 7. The diagnoses were-idiopathic: 17, ischemic stroke: 15, meningo-encephalitis: 8, Rasmussen's encephalitis (RE): 7, granuloma: 6, diabetic-non-ketotic-hyperosmolar-coma (DNKHC): 6, CNS malignancies (primary/secondary): 4, birth injury: 4, cerebral venous thrombosis: 3, CNS tuberculosis: 2, and cerebritis, HIV-related, toxemia of pregnancy, and MERRF one each. Patients of >40 years (n=21) had stroke (10), idiopathic (6), DNKHC (4) and metastasis (1) as common causes. Only 12 of them received single AED, while others required 2 or more AEDs to control the seizures. The outcome (n=72) was-controlled: 43 (59.7%); uncontrolled: 26 (36.1%) (RE: 7, idiopathic: 5, birth injury: 4, encephalitis: 3, malignancy: 2, granuloma and MERRF: 1 each) and three patients succumbed (encephalitis: 2, idiopathic: 1). Causes of EPC are varied and it depends on age. Underlying cause determined the outcome and could be refractory in RE, idiopathic, and when associated with birth injury, malignancy and encephalitis. Treatment of underlying cause is essential in addition to AEDs.

Three patients with neurosyphilis are reported. The first and third patients presented with convulsive status epilepticus and the second with non-convulsive status after penicillin administration. In all cerebrospinal fluid and the serum Venereal Disease Research Laboratory Test (VDRL) and Treponema Pallidum hemagglutination (TPHA) or fluorescent treponemal antibody absorption test (FTA-ABS) were positive, but HIV serology was negative. Their EEGs showed periodic, lateralized, epileptiform discharges (PLEDs) just after SE. The first and third patients had no history of epilepsy. Seizures started as focal motor attacks but then secondarily generalized. The first patient's cranial MRI showed cerebral atrophy and hyperintensity involving bilateral medial and anterior temporal regions, more prominent on the left and which disappeared after penicillin treatment. The second case, after receiving penicillin, had nonconvulsive SE, a clinical presentation suggesting a Jarisch-Herxheimer reaction (JHR). Her cranial MR revealed moderate cortical atrophy and widespread confluent hyperintense foci mainly in both periventricular areas, corona radiata and centrum semiovale. MRI of the third case showed a large, left sylvian, arachnoid cyst without mass effect. Executive dysfunction was observed in follow-up neuropsychological tests in all patients. When investigating status epilepticus, neurosyphilis as a cause must not be forgotten.

There have been no serial studies about neuroradiological findings of neurosyphilis in the literature. There have been only case reports concerning HIV negative patients with neurosyphilis. We present 8 HIV negative neurosyphilis patients two of whom are women. The mean age of the patients was 48 years+/-12.37. Five of the 8 patients had general paresis, two optic atrophy and one multiple cranial neuropathies. The CSF findings were quite similar in 6 of 8 patients. In half of the patients cranial MRI showed mild cerebral atrophy. Nonspecific hyperintense small foci in 3 patients are thought to be related to syphilis. Hyperintensity involving bilateral medial and anterior temporal regions more prominent on the left side was seen in one of the patients with general paresis. This finding may be due to cytotoxic edema associated with status epilepticus and may mimic herpes simplex and other limbic encephalitides. Though not typical, certain MRI findings guides for the diagnosis of neurosyphilis.
