Primary progressive aphasia (PPA) is a clinical dementia syndrome characterized by progressive decline in language function but relative sparing of other cognitive domains. There are three recognized PPA variants: agrammatic, semantic, and logopenic. Although each PPA subtype is characterized by the nature of the principal deficit, individual patients frequently display subtle impairments in ad...

AIMS Some studies show coronary heart disease (CHD) to be a risk factor for cognitive function while others report no association between the two. We examined the effect of CHD history and duration on cognition in a middle-aged population. METHODS AND RESULTS Data come from the Whitehall II study of 10,308 participants (33% women), aged 35-55 years at baseline (Phase 1; 1985-88). CHD events w...

BACKGROUND Cognitive decline caused by chemotherapy used in the treatment of malignant diseases was reported in several studies. ICCTF recommends the diagnosis of cognitive function in patient treated with chemotherapy. One of the suggested method is Verbal Fluency Test (VFT). METHODS Study was carried out on a group of 30 women with early breast cancer treated with adjuvant chemotherapy and ...

OBJECTIVE : This study addressed the issue of whether person naming deficits in mild cognitive impairment (MCI) occurred with deficits in person semantic knowledge and whether person knowledge was more impaired than general semantics. BACKGROUND : Recent definitions of MCI are beginning to encompass cognitive impairments outside the domain of episodic memory. Increasing evidence suggests that...

Tasks of fluency tap the ability to generate multiple responses spontaneously following a single cue or instruction. The present study compared the fluency performance of subjects with autism and clinical control subjects at two different levels of ability (high-functioning subjects with a verbal IQ of 76 or greater, and globally learning disabled subjects with a verbal IQ of 74 or below). A ba...

Postural instability and gait disorders (PIGD) in Parkinson's disease (PD) seem to be associated with executive dysfunction. We investigated which specific executive functions are associated with functional mobility in mildly affected PD patients. Functional mobility (Timed Up&Go Test, TUG), PIGD score, (spatial) working memory, set shifting, response inhibition and response generation were ass...

This article considers the semantic structure of the animal category from a cross-cultural developmental perspective. Children and adults from three North American communities (urban majority-culture, rural majority-culture, and rural Native American) were prompted to generate animal names, and the resulting lists were analyzed for their underlying dimensionality and for the typicality or salie...

Deep brain stimulation (DBS) of the subthalamic nucleus (STN) in individuals with Parkinson's disease (PD) has often been associated with reduced verbal fluency performance. This study aimed to directly assess semantic switching as a function of STN stimulation in PD participants with the Homophone Meaning Generation Test (HMGT). Seventeen participants with PD who had received STN DBS completed...
