Effects of a single dose of cortisol on the neural correlates of episodic memory and error processing in healthy volunteers.

RATIONALE: Neuropsychological impairments seen in depression may be secondary to hypercortisolaemia. Repeated cortisol administration impairs episodic memory with an alteration in event-related potentials (ERPs) recorded during information retrieval. It ...

Contribution of informant and patient ratings to the accuracy of the mini-mental state examination in predicting probable Alzheimers disease.

OBJECTIVES: To determine whether the accuracy of the Mini-Mental State Examination (MMSE) in predicting future Alzheimers disease (AD) could be improved by the addition of patient and informant ratings of cognitive difficulties. DESIGN: An inception ...

Perceiving numbers causes spatial shifts of attention.

Number symbols are part of our everyday visual world. Here we show that merely looking at numbers causes a shift in covert attention to the left or right side, depending upon the numbers magnitude. This observation implies obligatory activation of number ...

Predictors of cognitive impairment in advanced Parkinsons disease.

OBJECTIVE: To investigate the cognitive profile of patients with idiopathic Parkinsons disease and to determine the demographic and medical variables that contribute to the cognitive outcome. DESIGN: Retrospective cohort analysis. METHODS: 100 patients ...

Reduced serotonin 5-HT1A receptor binding in the temporal cortex correlates with aggressive behavior in Alzheimer disease.

Previous studies have implicated brain serotonin 5-HT(1A) receptors in several CNS functions, including cognition, mood and emotional states. In Alzheimer disease (AD), cognitive impairment and behavioral symptoms are the main clinical features. However, ...

Paying attention to emotion: an fMRI investigation of cognitive and emotional stroop tasks.

In this research, we investigated the degree to which brain systems involved in ignoring emotionally salient information differ from those involved in ignoring nonemotional information. The design allowed examination of regional brain activity, using ...

A three-factor model of cognition in Alzheimer disease.

OBJECTIVE: To use principal factors analysis to model cognition in Alzheimer disease. BACKGROUND: Earlier studies have used factor analysis to examine the effects on Alzheimer disease cognition of either heterogeneity in premorbid cognition or ...

Categorization of object descriptions in Alzheimers disease and frontotemporal dementia: limitation in rule-based processing.

Studies of semantic memory in probable Alzheimers disease (AD) have focused on the degradation of semantic knowledge, but other work in AD suggests an impairment in the semantic categorization processes that operate on this knowledge. We examined the ...

Quantitative EEG analysis in obsessive compulsive disorder.

Quantitative analysis of the EEG (q-EEG) in patients with obsessive compulsive disorder (OCD) showed a decreased beta and an increased theta power at frontotemporal regions. The patients who had higher scores in doubting test (Maudsley Obsessive ...
