What are the causes of reduced fit in scaling and clustering studies of semantic proximity data, and how else to measure them: a comment on Storms et al. (2003).

G. Storms, T. Dirikx, J. Saerens, S. Verstraeten, and P. P. De Deyn (2003) noted that the goodness-of-fit indices for scaling and clustering solutions of proximity data from populations with hypothesized semantic deficits tend to be reduced in comparison ...

Calculation impairment in neurodegenerative diseases.

We examined oral calculation in patients with corticobasal degeneration (CBD; N=17), frontotemporal dementia (FTD; N=17), and Alzheimers disease (AD; N=20), as well as 17 healthy seniors matched for age and education. Our calculation model involves at ...

Redundancy gain in the acallosal brain.

The authors measured simple reaction time (RT) to visual stimuli, presented either singly to 1 or the other visual field or in bilaterally presented pairs, to 2 women with callosal agenesis. The stimuli were either white against a black background or ...

Working memory in mild Alzheimers disease and early Parkinsons disease.

Alzheimers disease (AD) and Parkinsons disease (PD) impair working memory (WM). It is unclear, however, whether the deficits seen early in the course of these diseases are similar. To address this issue, the authors compared the performance of 22 ...

Neuropsychological prediction of conversion to dementia from questionable dementia: statistically significant but not yet clinically useful.

BACKGROUND: Verbal memory impairment, one of the earliest signs of Alzheimers disease (AD), may help identify people with cognitive impairment, insufficient for a diagnosis of dementia (questionable dementia: QD), at risk of developing AD. Other ...

Prefrontal cortex dysfunction during working memory performance in schizophrenia: reconciling discrepant findings.

Working memory (WM) deficits are a persistent, disabling and relatively treatment-resistant feature of schizophrenia that may underlie many cognitive deficits and symptoms. They are associated with prefrontal cortex dysfunction. While most neuroimaging ...

Interlocking finger test: a bedside screen for parietal lobe dysfunction.

This study sought to determine the utility of an interlocking finger task in screening for parietal lobe dysfunction. The ability of 69 patients to imitate a standardised set of four interlocking finger figures was compared with concurrent performance on ...

Accuracy of CT scan measurements of the medial temporal lobe in routine dementia diagnostics.

BACKGROUND: Atrophy of the medial part of the temporal lobe is seen in Alzheimers disease (AD). We studied the usefulness of CT scan measurements of the medial temporal lobe (MTL) in elderly with suspected dementia. METHODS: MTL measurements were done ...

Six-month neuropsychological outcome of medical intensive care unit patients.

OBJECTIVE: To examine neuropsychological function, depression, and quality of life 6 months after discharge in patients who received mechanical ventilation in the intensive care unit. DESIGN: Prospective cohort study. SETTING: Tertiary care, medical and ...

Effects of hormone replacement therapy on perceptual and cognitive event-related potentials in menopausal insomnia.

The influence of a combined estrogen-progestin regimen (Climodien, Lafamme) on auditory event-related potentials (ERPs) was investigated in a double-blind, placebo-controlled, comparative, randomized 3-arm trial phase (Climodien 2/3=estradiol valerate 2 ...
