The Bilingual Aphasia Test (BAT) is designed to be objective (so it can be administered by a lay native speaker of the language) and equivalent across languages (to allow for a comparison between the languages of a given patient as well as across patients from different institutions). It has been used not only with aphasia but also with any condition that(More)
All clinical evidence points to the fact that both languages of bilinguals are subserved by the left hemisphere in the same proportion as in unilinguals. Half of the experimental studies have reported no significant difference in lateralization between unilinguals and bilinguals. Those studies that have reported a difference contradict each other with(More)
After surgical removal of a parasitic cyst in the right prerolandic area, an educated 25-year-old male exhibited obvious deficits in one of his three languages (Gujarati), with no measurable deficits in the other two (French and Malagasy). The patient spoke all three languages fluently before the operation. Gujarati and Malagasy had been acquired in(More)
BACKGROUND The impact of an aging population on the psychiatric emergency service (PES) has not been fully ascertained. Cognitive dysfunctions aside, many DSM-IV disorders may have a lower prevalence in the elderly, who appear to be underrepresented in the PES. We therefore attempted to more precisely assess their patterns of PES use and their clinical and(More)
All of the experimental studies of the past 25 years combined and the meta-analyses of their findings have not advanced our knowledge of the lateralization of language in bilingual speakers one bit. We are left with a clutter of inherently uninterpretable contradictory results. Successive studies do not contribute a single brick to the edifice or a single(More)
To continue to search for a difference in language lateralization between bilinguals and unilinguals is at best a futile task in the face of all the clinical evidence to the contrary and inconsistent experimental findings. No amount of refining of dichotic, tachistoscopic, or concurrent task procedures, or statistical sophistication, is likely to tap the(More)
BACKGROUND The psychiatric emergency service (PES) is a major hub in the mental health care delivery system. The aim of this study was to more precisely define what psychiatrists consider to be a psychiatric emergency and to examine the underlying basis of this assessment. METHODS Over twenty-two thousand PES visits were assessed prospectively for(More)
