  • Dementia in the severely aphasic: Global Aphasia without hemiparesis—A stroke subtype simulating dementia
    American Journal of Alzheimers Disease and Other Dementias, 1999
    Co-Authors: Nages Nagaratnam, Catriona Mcneil
    Abstract:

    Patients with severe Aphasia and possible dementia cannot be adequately assessed for want of normative data. We describe four patients with Global Aphasia without hemiparesis who were referred for evaluation of dementia without the knowledge that they had previously suffered a stroke. All four had no neurological deficits except for language dysfunction. The study looked at the utility of the commonly-used dementia scales in patients with severe Aphasia and possible dementia. The findings indicated the limitations of verbal, non-verbal cognitive tests and the reliance on informant reports. Appropriate weighting of these may help in arriving at a more accurate diagnosis. Until guidelines for a reliable criteria are established, the clinician should assess the patient in a Global way and not just in one aspect of the patient's symptomatology. Dementia in the severely aphasic remains a diagnostic challenge and merits further study.

  • Speech Recovery Following Global Aphasia Without Hemiparesis
    Neurorehabilitation and Neural Repair, 1996
    Co-Authors: Nages Nagaratnam, Robyn Barnes, S. Nagaratnam
    Abstract:

    Twelve patients with Global Aphasia without hemiparesis were studied to determine site of infarction and relate this to severity of Aphasia and recovery from it. All patients were studied with CT scans without contrast and the site of the lesion or lesions deter mined by tracing the lesion from standard horizontal slices taken 10 mm apart. Lan guage impairment was determined by the Boston Diagnostic Aphasia Examination and the Aphasia Language Performance Scales, done within four to eight days after onset and at three months following the stroke. All patients had deficits in all language modalities with reduced verbal output, impaired comprehension, impaired reading, writing, and repetition.The CT scans showed that four patients had lesions in language areas located ante riorly, four had lesions posteriorly, and in four the lesions were both anterior and posterior.Recovery was correlated with lesion location and Aphasia severity. Those with initially severe Aphasia had less good recovery than those with m...

  • Global Aphasia without Hemiparesis
    Neurorehabilitation and Neural Repair, 1990
    Co-Authors: Nages Nagaratnam, K. Patston
    Abstract:

    This case report describes a patient with Global Aphasia with little or no hemiparesis. Initially, computed tomography (CT) revealed a petechial hemorrhagic infarction anteriorly and another infarction posteriorly in the left hemisphere. Subsequently, CT showed a large confluent infarction in the territory of the left middle cerebral artery. At the end of 12 months, speech recovery was poor. Key Words: Global Aphasia—Hemiparesis—Computed tomography.

  • re education of gestural communication in a case ol chronic Global Aphasia and limb apraxia
    Cognitive Neuropsychology, 1991
    Co-Authors: Roberto Cubelli, Piera Trentini, Carmelo G Montagna
    Abstract:

    Abstract Since neuropsychological studies have shown that Global aphasics can communicate by gestures, much rehabilitative effort has been devoted to potentiate the residual nonverbal abilities, and especially the effectiveness of gestural communication. Most therapists have tried to teach aphasic patients to memorise specific gestures taken from well-codified sign systems, but have failed to demonstrate substantial improvements in everyday-life communication. In this article we report the results of pantomimic training of GM, a 63-year-old woman with chronic Global Aphasia and severe limb apraxia, who did not show any improvements following standardised speech re-education. A special pantomime training program was devised, aimed to focus her attention on critical features of gestures. After treatment the patient showed a significant improvement of gestural ability measured by means of a pantomimic referential task.
