Memory impairment is the main clinical feature in Alzheimer disease (AD), whereas in frontotemporal lobar degeneration (FTLD) behavioral and language disorders predominate. Objectives To investigate possible differences between the neuropsychological performance in FTLD and AD. Methods Fifty-six AD patients (mean age=72.98±7.43; mean schooling=9.62±4.68; 35 women and 21 men), 17 FTLD patien...

AIM The aim of the study was to test whether children with a diagnosis of ADHD at the age of 7-16 years have deficits in visual-spatial, visual memory, planning, and organisation of the visual-motor functions. METHODS The study included 186 unrelated patients aged 7-16 years diagnosed with ADHD. The control group consisted of 156 healthy individuals aged 7-16 years. The methods applied were t...

STUDY OBJECTIVES Rapid eye movement (REM) sleep is considered critical to the consolidation of procedural memory - the memory of skills and habits. Many antidepressants strongly suppress REM sleep, however, and procedural memory consolidation has been shown to be impaired in depressed patients on antidepressant therapy. As a result, it is important to determine whether antidepressive therapy ca...

We present a general framework for representing belief-revision rules and use it to characterize Bayes’s rule as a classical example and Je¤rey’s rule as a non-classical one. In Je¤rey’s rule, the input to a belief revision is not simply the information that some event has occurred, as in Bayes’s rule, but a new assignment of probabilities to some events. Despite their di¤erences, Bayes’s and J...

the authors present new data on Mytilus edulis shells REY content and fractionation as a potential proxy for REY content in seawater. The potential impact of pH and temperature on such REY signal in the mussel shells is investigated, as well as the potential process of shells REY incorporation. Part of the paper also deals with shell preparation and analytical procedures for analyses of such lo...

It was hypothesized that subjective memory complaints represent the earliest sign of dementia in carriers of the presenilin-1 (PS1) mutation. A total of 122 subjects (44 males, 78 females) were included in this study. Forty of them were positive for the mutation in the PS1 gene (mutation positive, MP) whereas 82 showed negative results (mutation negative, MN). Subjects were active, functionally...

The origin of deep-sea sediments in the western North Pacific Ocean, which are significantly enriched rare-earth elements and yttrium (REY), its paleoceanographic implications have been poorly constrained. Here, we investigated stratigraphic variations chemical compositions textures ferromanganese (Fe–Mn) micronodules separated from sediments. characteristics an extremely REY-rich mud layer var...

Whether long-term blood pressure (BP) variability throughout young adulthood is associated with cognitive function in midlife remains uncertain. Using data from the Coronary Artery Risk Development in Young Adults (CARDIA), which recruited healthy young adults aged 18 to 30 years (mean age, 25 years) at baseline (Y(0)), we assessed BP variability by SD and average real variability (ARV) for 25 ...

With aging, several cognitive skills inevitably decline. However, cognitive losses do not occur homogenously in all elderly people, differing in number and severity of affected cognitive functions. These differences could be exacerbated by socioeconomic differences in a developing country like Brazil. Objectives to characterize the cognitive functioning of healthy elderly subjects whose socio...
