The number of people diagnosed with Alzheimer's disease (AD), a progressive and terminal kind of dementia, continues to rise with an estimated 14 million Americans affected by 2050. Prior to an AD diagnosis, many individuals are diagnosed with mild cognitive impairment (MCI) and have similar, but less severe, symptoms as those with AD. A common…

Purpose: Speech perception in noise becomes difficult with age but can be facilitated by audiovisual (AV) speech cues and sentence context in healthy older adults. However, individuals with Alzheimer's disease (AD) may present with deficits in AV integration, potentially limiting the extent to which they can benefit from AV cues. This study…

Background: According to some studies, sentence comprehension is diminished in Alzheimer's disease (AD) patients, but they differ on what underlies the sentence comprehension impairment. Sentence comprehension in AD patients has been studied mainly in the English language. It is less clear how patients with AD speaking a morphologically rich…

As the boom in the older adult population continues to grow, so too grows the number of persons suffering from cognitive diseases, such as dementia of the Alzheimer's type (DAT). Older Latinos diagnosed with the disease make up 4 percent (200,000) of the current population; however, little research on bilinguals with DAT has been carried out…

Source monitoring is the process of making judgments about the origin of memories. There are three categories of source monitoring: reality monitoring (discrimination between self- versus other-generated sources), external monitoring (discrimination between several external sources), and internal monitoring (discrimination between two types of…

Retrieval of proper names is a cause of concern and complaint among elderly adults and it is an early symptom of patients suffering from neurodegenerative diseases such as Alzheimer's disease (AD). While it is well established that AD patients have deficits of proper name retrieval, the nature of such impairment is not yet fully understood.…

Dementia may be more common in older adults with intellectual disability (ID) than in the general population. The increased risk for Alzheimer's disease in people with Down syndrome (DS) is well established, but much less is known about dementia in adults with ID who do not have DS. We estimated incidence rates from a longitudinal study of…

Purpose: Quality of Life (QoL) has become increasingly valued as a key outcome in dementia both in clinical practice and in research. This study compares the QoL of long-term residents with dementia as assessed by the individuals, their relatives, and their care staff. Design and Methods: Data on residents with dementia were collected in 11…

Purpose of the study: To present a critical comparative review of published tools measuring the person-centeredness of care for older people and people with dementia. Design and Methods: Included tools were identified by searches of PubMed, Cinahl, the Bradford Dementia Group database, and authors' files. The terms "Person-centered,"…

Purpose: In this study, the authors investigated emotional prosody in patients with moderate Dementia of the Alzheimer's type (DAT) With Late Onset. It was expected that both expression and reception of prosody would be impaired relative to age-matched controls. Method: Twenty DAT and 20 control participants engaged in 2 expressive and 2 receptive…

Temporal preparation was assessed in 15 Alzheimer's disease (AD) patients, 20 persons with mild cognitive impairment (MCI) and 28 healthy older adults. Participants completed a simple reaction time task in which the preparatory interval duration varied randomly within two blocks (short versus long temporal window). Results indicated that AD and…

Semantic deficits in Alzheimer's disease have been widely documented, but little is known about the integrity of semantic memory in the prodromal stage of the illness. The aims of the present study were to: (i) investigate naming abilities and semantic memory in amnestic mild cognitive impairment (aMCI), early Alzheimer's disease (AD) compared to…

Intelligence is an important indicator of physical, mental and social well-being. In old age, intelligence is also associated with a higher quality of life and better health. Heritability studies have shown that there are strong genetic influences, yet unknown, on intelligence, including in old age. Other approaches may be useful to investigate…

Intellectual disability (ID) is a prevalent form of non-progressive cognitive impairment. The objectives of this articles are: to analyze the changes of ID in China, including its definition, prevalence, rehabilitation, education, vocational development, social life and support services; to review and to compare the issues of intellectual…

This study investigated the relationship between semantic and episodic memory as they support lexical access by healthy younger and older adults and individuals with Alzheimer's disease (AD). In particular, we were interested in examining the pattern of semantic and episodic memory declines in AD (i.e., word-finding difficulty and impaired recent…
