Background: Addenbrooke's Cognitive Examination III (ACE-III) was developed as a screening tool for cognitive disorders. Many countries have proven the cultural adaptation, reliability and validity of ACE-III. Aims: To make cultural adaptations of ACE-III for the Turkish population and to examine its validity and reliability. Methods &…

Purpose: This research investigated the nature of cognitive decline in prodromal Alzheimer's disease (AD), particularly in mild cognitive impairment, amnestic type (aMCI). We assessed language in aMCI as compared with healthy aging (HA) and healthy young (HY) with new psycholinguistic assessment of complex sentences, and we tested the degree to…

There is a recognised need for research that illuminates mutually beneficial connections among performance, ageing, disability theory, and praxis. One such project is the Memory Ensemble™, an improvisational theatre intervention for persons with early stage Alzheimer's disease and related dementias (ADRD). This case study explores how the…

Studies have shown that the "Four Seasons" music may enhance the autobiographical performance of Alzheimer's disease (AD) patients. We used a repeated measures design in which autobiographical recall of 12 mild AD patients was assessed using a free narrative method under three conditions: (a) in "Silence," (b) after being exposed to the opus "Four…

Alzheimer's dementia (AD) is a progressive, degenerative disease that occurs in the cerebral cortex due to increased levels of glutamate, the proliferation of plaque-forming amyloid beta proteins, and reactive gliosis. Establishing behavioral indicators of the disease (e.g., impairments of episodic memory) and use of neuroimaging technology…

Aged dogs exhibit a spectrum of cognitive abilities including a syndrome similar to Alzheimer's disease. A major impediment to research so far has been the lack of a quick and accurate test of visuospatial memory appropriate for community-based animals. We therefore report on the development and validation of the Canine Sand Maze. A 4.5-m-diameter…

Recent research has demonstrated that Alzheimer's disease (AD) affects the visual sensory pathways, producing a variety of visual deficits, including the capacity to perceive structure-from-motion (SFM). Because the sensory areas of the adult brain are known to retain a large degree of plasticity, the present study was conducted to explore whether…

In the therapeutic void created by over 20 failed Alzheimer's disease drugs during the past decade, a new marketplace of "brain fitness" technology products has emerged. Ranging from video games and computer software to mobile phone apps and hand-held devices, these commercial products promise to maintain and enhance the memory,…

Adults with Down syndrome and early stage Alzheimer's disease showed decline in their ability to selectively attend to stimuli in a multitrial cancellation task. They also showed variability in their performance over the test trials, whereas healthy participants showed stability. These changes in performance were observed approximately 2 years…

Frontotemporal lobar degeneration (FTLD) often overlaps clinically with corticobasal syndrome (CBS) and progressive supranuclear palsy (PSP), both of which have prominent eye movement abnormalities. To investigate the ability of oculomotor performance to differentiate between FTLD, Alzheimer's disease, CBS and PSP, saccades and smooth pursuit were…

Purpose: The study aim was to develop a measure of self-reported quality of life (QoL) for people with mild to moderate dementia based on their views--the Bath Assessment of Subjective Quality of Life in Dementia (BASQID). Design and Methods: We developed the measure through multiple stages. Two field tests of the measure (ns = 60 and 150)…

A profound loss of cortical cholinergic innervation is a nearly invariant feature of advanced Alzheimer's disease (AD). The temporal course of this lesion and its relationship to other aspects of the disease have not yet been fully clarified. Despite assertions to the contrary, a review of the evidence suggests that a perturbation of cholinergic…

The validity and reliability of a novel route learning test were examined to assess the effectiveness of its use in evaluating spatial memory in healthy older adults and patients with Alzheimer's disease (AD). The Puget Sound Route Learning Test was significantly correlated with an existing measure of cognitive ability, the Dementia Rating Scale.…
