Personality and behavioural changes do not precede memory problems as possible signs of dementia in ageing people with Down syndrome

Objective: The objective was to find out whether changes in personality and adaptive functioning or memory processes decline first in ageing people with Down syndrome. Methods: The authors measured these variables cross-sectionally in a Dutch sample (22 to 62 years of age) of 68 institutionalised people with Down syndrome. Results: The scores on all the variables except one of the temperament scales were found to decline gradually with increasing age, but deterioration of episodic memory started earlier. Conclusions: The authors argued that a subset of their sample suffered from dementia. Furthermore, the data suggested that immediate memory impairment is one of the earliest signs of the disease in people with Down syndrome, just as it is in the general population.

This book examines the major progress made in recent psychological science in understanding the cognitive control of thought, emotion, and behaviour and what happens when that control is diminished as a result of ageing, depression, developmental disabilities, or psychopathology. Each chapter of this volume reports the most recent research by a leading researcher on the international stage. Topics include the effects on thought, emotion, and behaviour by limitations in working memory, cognitive control, attention, inhibition, and reasoning processes. Other chapters review standard and emerging research paradigms and new findings on limitations in cognitive functioning associated with ageing and psychopathology. The explicit goal behind this volume was to facilitate cross-area research and training by familiarizing researchers with paradigms and findings in areas different from but related to their own.

The main purpose of the current investigation was to examine the predictive utility of two sets of criteria for mild cognitive impairment (MCI). A second purpose was to determine the incidence of MCI in a longitudinal, population-based sample of the oldest old in Sweden. The participants were from the larger ‘Origins of Variance in the Old-Old: Octogenarian Twins’ (OCTO-Twin) study, identified through the Swedish Twin Registry. Participants were initially aged 80 or above with a mean age of 83 and were re-examined after two, three, six and eight years. The sample for this study consisted of 263 elders that were randomly selected singletons from twin pairs. Mild cognitive impairment was rated at baseline using both Petersen’s and Ritchie’s criteria. Petersen’s criteria emphasize memory and memory complaint whereas Ritchie’s criteria use a broader set of cognitive indicators. The incidence rate was comparable to that of other studies, however, neither set of criteria predicted subsequent dementia. The failure to confirm subsequent dementia suggests that there may be many sources of MCI in very late life besides incipient dementia. The presence of a key informant, as well as the weighting of performance across domains by an experienced clinician, both of which are hard to quantify, may be the key elements that give predictive values to MCI in prior studies.
Creating successful dementia care settings volume 2: maximising cognitive and functional abilities

Examines the critical features of formal care settings that either support people with dementia or create unmanageable barriers to their ability to function successfully. This volume demonstrates how to avoid unnecessary helplessness. Simple changes to the facility environment can help to support remaining skills. Step by step processes are identified.
