Objectives Individuals with prenatal alcohol exposure (PAE) may be diagnosed with fetal alcohol spectrum disorder (FASD) if they have significant impairments in at least three different areas of functioning. The areas of functioning are viewed as separate entities for diagnostic consideration; however, some areas, including executive functioning (E...

Objective We investigated group differences in current source density (CSD) patterns from EEG signals before and after a working memory (WM) task performed by mild cognitive impaired (MCI) subjects and healthy elderly (HE). Methods EEG was recorded during N-back WM tasks in 41 age-, sex- and education-matched participants divided into MCI (N = 19)...
Article
Background and objective: In this study we investigate whether or not event-related potentials (ERP) and/or event-related (de)synchronization (ERD/ERS) can be used to differentiate between 27 healthy elderly (HE), 21 subjects diagnosed with mild cognitive impairment (MCI) and 15 mild Alzheimer's disease (AD) patients. Methods: Using 32-channel E...

Introduction: Alzheimer’s disease (AD) affects above 24 million people in the world. Petersen et al. developed the concept of mild cognitive impairment (MCI), thus describing a state of pre-dementia characterized by intermediate symptoms between normal aging and dementia caused by the onset of AD. Electroencephalographic (EEG) records in patients w...

Amnestic mild cognitive impairment (aMCI) represents a group of individuals who are highly likely to develop Alzheimer's disease (AD). Although aMCI is typically conceptualized as involving predominantly deficits in episodic memory, recent studies have demonstrated that deficits in executive functioning may also be present, and thorough categorizat...

The primary goal of this study was to evaluate the false recognition phenomenon in persons with frontotemporal dementia (FTD) and those with Lewy-body disease (LBD). Patients with LBD (n=10) or FTD (n=15) and their corresponding controls (n=30) were subjected to the Deese-Roediger-McDermott (DRM) paradigm to induce false recognition. Patients were...

Diagnosis of different types of dementia is often based on clinical symptomatology rather than underlying pathology; therefore, accurate diagnosis depends on a thorough description of cognitive functioning in different dementias. Furthermore, direct comparison of cognitive functions between different types of dementia is necessary for differential...
Article
A thorough description of cognitive functioning in individuals with dementia and those at risk of developing dementia is essential for early and accurate diagnosis. Executive functioning is one cognitive domain in which deficits have been reported in various types of dementia, including mild cognitive impairment (MCI, often a transitional stage bet...
