It is not in the best interest of persons with epilepsy to deny the possibility that seizures could cause enduring behavioral disturbances. Rather, it is essential to pursue clinical and animal investigations in order to identify any such changes that might occur and to elucidate their mechanisms. Many testable hypotheses can be developed from existing(More)
Dehydroepiandrosterone (DHEA) and its metabolites, DHEA-sulphate (DHEA-S) and androsterone, have neurosteroid activity. In this study, we examined whether DHEA, DHEA-S and androsterone, can influence serotonin (5-HT) neuronal firing activity via modulation of γ-aminobutryic acid (GABA(A)) receptors. The firing of presumed 5-HT neurones in a slice(More)
BACKGROUND It is important to establish the validity of diagnostic coding in administrative datasets used in stroke and transient ischemic attack (TIA) research. This study examines the accuracy of emergency department (ED) TIA diagnosis and final diagnostic coding after hospital admission. METHODS Using administrative datasets, we identified all patients(More)
Unilateral microinjections of kainic acid (4.7 nmol) were made into the dorsal hippocampus of 17 unanesthetized freely moving cats. These injections provoked an acute period of intense seizure activity (first 48-72 h) which in 10 cats was followed by a chronic period of recurrent spontaneous complex partial seizures persisting for as long as the cats were(More)
The study aims were to determine the prevalence of positive syphilis serology and meningovascular neurosyphilis (NS) in patients admitted with transient ischaemic attack (TIA) and stroke to a tertiary hospital serving a culturally diverse community. A retrospective cohort analysis was conducted using routinely collected administrative data and medical(More)
Optic neuropathy and transverse myelitis (TM) are common symptoms of multiple sclerosis (MS) but may also be seen in association with the antibody-mediated autoimmune disorder, neuromyelitis optica (NMO). We report a female patient presenting with intractable vomiting and hiccups and TM shortly followed by an acute encephalopathy, most likely due to NMO(More)
Granulomatous interstitial nephritis (GIN) is an uncommon cause of renal failure, which may be caused by drugs. Levetiracetam is an increasingly used anti-epileptic medication that is not known to cause renal toxicity in adults. To our knowledge, levetiracetam has not previously been reported as a cause of GIN. We report the case of a 69-year-old woman who(More)
This study extends our previous work in which we described the presence of an interictal behavioral disturbance in a chronic animal model of temporal lobe epilepsy (TLE). In this study, we investigated the cerebrospinal fluid (CSF) neurotransmitter changes underlying the development of chronic recurrent seizures of temporal lobe origin and interictal(More)
We report a 37-year-old woman with a 2 month history of proximal muscle weakness and extremely high creatine kinase (21,808 U/L) due to necrotizing auto-immune myositis (NAM) in association with anti-synthetase syndrome. Myositis-specific auto-immune antibody panel was positive for anti-Signal recognition particle and anti-PL-12. CT scan of the chest(More)
