Pragmatic language production deficits in Parkinson’s disease

Pragmatic language production deficits in Parkinson’s disease

This study examines pragmatic language production deficits in people with Parkinson’s disease (PD). Participants (PD and non-PD) were interviewed and their responses coded for degree of informativeness. PD participants were more under-informative than non-PD participants. Response underinformativeness was associated with decreased executive control, mental status, and speech act comprehension m...

Language functions in right-hemisphere damage and schizophrenia: apparently similar pragmatic deficits may hide profound differences.

Sir, In a recent article discussing the cognitive roots of schizophrenic communicative behaviour, Mitchell and Crow (2005) emphasized the importance of full access to right hemisphere language functions to ensure successful social communication. Based on the literature describing communicative deficits among right-hemisphere-damaged (RHD) patients, as well as on the literature reporting functio...

Language deficits in pre-symptomatic Huntington's disease: evidence from Hungarian.

A limited number of studies have investigated language in Huntington's disease (HD). These have generally reported abnormalities in rule-governed (grammatical) aspects of language, in both syntax and morphology. Several studies of verbal inflectional morphology in English and French have reported evidence of over-active rule processing, such as over-suffixation errors (e.g., walkeded) and over-...

Automatic, unsupervised classification of dyskinesia in patients with Parkinsons Disease

One of the characteristic symptoms of patients with Parkinson Disease (PD) is a rigidity of movement. These symptoms disappear after administration of Levodopa. However, the long-term use of levodopa causes involuntary movements (dyskinesia). A proper diagnosis requires an automatic, unsupervised method for the detection and classification of levodopa induced dyskinesia. The main problem, howev...
