Direct linkChow, Maggie L.; Brambati, Simona M.; Gorno-Tempini, Maria Luisa; Miller, Bruce L.; Johnson, Julene K. – Brain and Cognition, 2010
Modern cognitive neuroscientific theories and empirical evidence suggest that brain structures involved in movement may be related to action-related semantic knowledge. To test this hypothesis, we examined the naming of environmental sounds in patients with corticobasal degeneration (CBD) and progressive supranuclear palsy (PSP), two…

Chronic traumatic encephalopathy is a progressive tauopathy that occurs as a consequence of repetitive mild traumatic brain injury. We analysed post-mortem brains obtained from a cohort of 85 subjects with histories of repetitive mild traumatic brain injury and found evidence of chronic traumatic encephalopathy in 68 subjects: all males, ranging…

Kelsey, Susan G.; Laditka, Sarah B.; Laditka, James N. – Gerontologist, 2010
Purpose: This study examines transitioning residents with Alzheimer's disease or a related disorder (ADRD) from assisted living facilities (ALFs) to memory care units (MCUs) from the perspective of 3 ALF organizational models: freestanding ALFs, ALFs with MCUs, and ALFs in continuing care retirement communities (CCRCs) with MCUs. Design and…

Middei, Silvia; Roberto, Anna; Berretta, Nicola; Panico, Maria Beatrice; Lista, Simone; Bernardi, Giorgio; Mercuri, Nicola B.; Ammassari-Teule, Martine; Nistico, Robert – Learning & Memory, 2010
B6-Tg/Thy1APP23Sdz (APP23) mutant mice exhibit neurohistological hallmarks of Alzheimer's disease but show intact basal hippocampal neurotransmission and synaptic plasticity. Here, we examine whether spatial learning differently modifies the structural and electrophysiological properties of hippocampal synapses in APP23 and wild-type mice. While…

Prasher, V. P.; Airuehia, E.; Carey, M. – Journal of Applied Research in Intellectual Disabilities, 2010
Dementia with Lewy bodies (DLB) is the second commonest cause of dementia in the general population. Several researches have established an association between Down syndrome (DS) and Alzheimer's disease. Very few studies have however showed such an association between dementia with Lewy bodies and Down syndrome. The occurrence of DLB in persons…

Wittich, Walter; Phillips, Natalie; Nasreddine, Ziad S.; Chertkow, Howard – Journal of Visual Impairment & Blindness, 2010
Evaluating the cognitive status of individuals who are visually impaired is limited by the design of the test that is used. This article presents data on the sensitivity and specificity of the version of the Montreal Cognitive Assessment for people who are visually impaired. The original validation data were reanalyzed, excluding the five visual…

Jian, Xue-Qiu; Wang, Ke-Sheng; Wu, Tie-Jian; Hillhouse, Joel J.; Mullersman, Jerald E. – Journal of Abnormal Child Psychology, 2011
Twin and family studies have shown that genetic factors play a role in the development of conduct disorder (CD). The purpose of this study was to identify genetic variants associated with CD using a family-based association study. We used 4,720 single nucleotide polymorphisms (SNPs) from the Illumina Panel and 11,120 SNPs from the Affymetrix 10K…

Jacobs, Heidi I. L.; Van Boxtel, Martin P. J.; Uylings, Harry B. M.; Gronenschild, Ed H. B. M.; Verhey, Frans R.; Jolles, Jelle – Brain and Cognition, 2011
Cortical grey matter atrophy patterns have been reported in healthy ageing and Alzheimer disease (AD), but less consistently in the parietal regions of the brain. We investigated cortical grey matter volume patterns in parietal areas. The grey matter of the somatosensory cortex, superior and inferior parietal lobule was measured in 75 older adults…

Brayne, Carol; Ince, Paul G.; Keage, Hannah A. D.; McKeith, Ian G.; Matthews, Fiona E.; Polvikoski, Tuomo; Sulkava, Raimo – Brain, 2010
The potential protective role of education for dementia is an area of major interest. Almost all older people have some pathology in their brain at death but have not necessarily died with dementia. We have explored these two observations in large population-based cohort studies (Epidemiological Clinicopathological Studies in Europe; EClipSE) in…

Williams, Lynne J.; Abdi, Herve; French, Rebecca; Orange, Joseph B. – Journal of Speech, Language, and Hearing Research, 2010
Purpose: In communication disorders research, clinical groups are frequently described based on patterns of performance, but researchers often study only a few participants described by many quantitative and qualitative variables. These data are difficult to handle with standard inferential tools (e.g., analysis of variance or factor analysis)…

Peters, Frederic; Majerus, Steve; De Baerdemaeker, Julie; Salmon, Eric; Collette, Fabienne – Neuropsychologia, 2009
A decrease in verbal short-term memory (STM) capacity is consistently observed in patients with Alzheimer's disease (AD). Although this impairment has been mainly attributed to attentional deficits during encoding and maintenance, the progressive deterioration of semantic knowledge in early stages of AD may also be an important determinant of poor…

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…

Pyo, Geunyeong; Ala, Tom; Kyrouac, Gregory A.; Verhulst, Steven J. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
The purpose of the present study was to investigate the validity of the Working Group's Autobiographical Memory Test as a dementia screening tool for individuals with moderate to severe intellectual disabilities (ID). Twenty-one participants with Dementia of Alzheimer's Type (DAT) and moderate to severe ID and 42 controls with similar levels of ID…

Garcia-Osta, Ana; Alberini, Cristina M. – Learning & Memory, 2009
The amyloid precursor protein (APP) undergoes sequential cleavages to generate various polypeptides, including the amyloid [beta] (1-42) peptide (A[beta][1-42]), which is believed to play a major role in amyloid plaque formation in Alzheimer's disease (AD). Here we provide evidence that, in contrast with its pathological role when accumulated,…

Gronholm-Nyman, Petra; Rinne, Juha O.; Laine, Matti – Neuropsychologia, 2010
We studied how subjects with mild cognitive impairment (MCI), early Alzheimer's disease (AD) and age-matched controls learned and maintained the names of unfamiliar objects that were trained with or without semantic support (object definitions). Naming performance, phonological cueing, incidental learning of the definitions and recognition of the…
