BACKGROUND Weight gain has been recognized as a common adverse effect of valproic acid (VPA) that leads to discontinuation in some patients but its incidence and correlates have been rarely studied. METHODS We have analyzed the records retrospectively and interviewed 70 adult patients attending an epilepsy clinic on VPA mono- or polytherapy followed over(More)
Monotherapy has been promoted as the ideal in epilepsy treatment because of reduced side effects, absence of drug interactions, better compliance, lower cost and, in many cases, improved seizure control compared to polytherapy. The question of monotherapy vs. polytherapy has assumed increasing importance with the availability of multiple new antiepileptic(More)
BACKGROUND/OBJECTIVE There are presently 26 different generic preparations for five brand name antiepileptic drugs (AEDs) on the Canadian market with others likely to be released in the near future. The purpose of this review is to examine the basis for the controversy surrounding generic substitution for brand name antiepileptic drugs, to present the(More)
In response to increasing cost pressures, healthcare systems are encouraging the use of generic medicines. This review explores potential problems with generic substitution of antiepileptic drugs (AEDs). A broad search strategy identified approximately 70 relevant articles. Potential problems with generic substitution included: The limited evidence (mainly(More)
Vigabatrin (VGB) has been shown in a number of clinical trials with varying designs to be effective and well-tolerated as both add-on therapy and monotherapy in epilepsy with partial seizures with or without secondary generalization as well as in infantile spasms. The present study is an open, long-term (1 year) extension of a randomized double-blind(More)
A questionnaire survey compared the psychosocial effects of epilepsy in 60 patients without major organic pathology (selected cases with temporal lobe epilepsy or primary generalized epilepsy) with those of matched (duration of illness, sex) patients with narcolepsy/cataplexy and with those of age- and sex-matched controls. Comparing epileptic patients with(More)
A longitudinal study of three patients with CT-scan documented paramedian thalamic infarctions (bilateral, primarily right, unilateral left) is reported and the neuropsychology of human paramedian thalamic infarction is reviewed. The neuropsychological deficits following these selected lesions, the nature of the clinical memory disorder, and the(More)
Twelve non-epileptic patients with psychogenic "convulsive" pseudoseizures were studied to delineate useful diagnostic criteria. Six patients had severe psychological disturbances, a long pseudoseizure history and a poor prognosis, while the other six showed little psychopathology, had undergone a recent emotional trauma to account for their pseudoseizures(More)
OBJECTIVES Based on dose predictions from animal and human volunteer studies, most patients enrolled in initial randomized controlled trials of topiramate as adjunctive therapy in adults with partial-onset seizures were randomized to >or= 600 mg/day topiramate. Subsequent experience suggests that dosage needs were overestimated. This double-blind,(More)
