Benzodiazepine Use and Cognitive Decline in Elderly With Normal Cognition.
Authors: Zhang Y, Zhou XH, Meranus DH, Wang L, Kukull WA Abstract Benzodiazepine (BZD) use may be associated with dementia. However, differing opinions exist regarding the effect of BZDs on long-term changes in cognition. We evaluated the association between BZD use and cognitive decline in the elderly with normal cognition from the National Alzheimer's Disease Coordinating Center's Uniform Data Set. The study exposure, BZD use, was classified 2 ways: any-use (reported BZD use at a minimum of 1 Alzheimer's disease center (ADC) visit) and always-use (reported BZD use at all ADC visits). The reference group included ...

Adaptive, Dose-finding Phase 2 Trial Evaluating the Safety and Efficacy of ABT-089 in Mild to Moderate Alzheimer Disease.
Authors: Lenz RA, Pritchett YL, Berry SM, Llano DA, Han S, Berry DA, Sadowsky CH, Abi-Saab WM, Saltarelli MD Abstract ABT-089, an α4β2 neuronal nicotinic receptor partial agonist, was evaluated for efficacy and safety in mild to moderate Alzheimer disease patients receiving stable doses of acetylcholinesterase inhibitors. This phase 2 double-blind, placebo-controlled, proof-of-concept, and dose-finding study adaptively randomized patients to receive ABT-089 (5, 10, 15, 20, 30, or 35 mg once daily) or placebo for 12 weeks.

Trajectory of Mobility Decline by Type of Dementia.
Authors: Tolea MI, Morris JC, Galvin JE Abstract Cognitive and physical aspects of functionality are closely related. However, whether physical decline differs by dementia type and progression rate is debatable. To address these issues, we conducted a longitudinal study of 766 older adults whose physical performance and cognitive status were assessed annually with standard assessment tools [eg, Physical Performance Test, Clinical Dementia Rate (CDR)] for 8 years. Compared with participants who remained cognitively normal, those progressing to later-stage dementia (CDR=1) declined in their mobility by a factor of 2.82 (P

Onset of Mild Cognitive Impairment in Parkinson Disease.
CONCLUSIONS: Longitudinal disease-state models support a prodromal dementia stage (PD-MCI) marked by early declines in working memory and visuospatial processing beginning 5 years before clinical diagnosis of PDD. Cognitive declines in PD affect motor ability (bradykinesia), working memory, and processing speed (bradyphrenia) resulting in PD-MCI where visuospatial imagery and memory retrieval deficits manifest before eventual development of overt dementia. Tests of episodic memory may not be sufficient to detect and quantify cognitive decline in PD. PMID: 25850732 [PubMed - as supplied by publisher] (Source: Alzheimer ...

Cancer and Dementia: It’s Complicated
The relationship between dementia and cancer is complex. A wealth of observational data suggest (1) reduced risk of certain cancers in Alzheimer and Parkinson diseases; and (2) increased risk of other cancers in Parkinson disease. These relationships persist despite correcting for reporting artifacts and survival bias. Several potential mechanisms have been proposed and warrant further investigation. Aging is a risk factor for both. Common environmental exposures, such as smoking, may play roles. Common mechanisms such as chronic inflammation and immunosenescence, and common risk factors such as diabetes and obesity, have ...

Memory Profiles in Pathology or Biomarker Confirmed Alzheimer Disease and Frontotemporal Dementia
Conclusions: AD participants showed more rapid forgetting than bvFTD, and both groups showed more rapid forgetting than controls. In contrast, bvFTD did not conform to a more dysexecutive pattern of performance as patient groups committed similar number of intrusion errors and showed comparably low rates of improvement on cued recall and recognition trials. For patients with neuroimaging, there were no group differences in medial temporal volumes, which was the only significant predictor of consolidation for both dementia groups.

RESULTS:: The patient groups did not differ in modified Mini Mental State Examination scores. AD patients scored lowest on the Five-Words Test overall, and showed the greatest reduction from immediate total recall to delayed free recall relative to the other 2 groups, consistent with a predominantly consolidation deficit.

Caregivers were dichotomized into low-burden and high-burden groups based upon: (1) UD score using quartile cutoffs; and (2) MD model via exploratory cluster analysis.

Because therapeutic regimens are limited, modification of lifestyle behaviors may offer the best means for disease control. To test the hypotheses that lifestyle factors are related to lower risk of dementia in the oldest-old, we analyzed data from The 90+ Study, a population-based longitudinal cohort study initiated in 2003. This analysis included 587 participants (mean age=93 y) seen in-person and determined not to have dementia at enrollment. Information on lifestyle...

At baseline, 32.4% of participants had diabetes and 15.8% developed diabetes during the study. During the study period, 22.8% of participants died. In joint longitudinal-survival models, those with baseline diabetes experienced faster cognitive decline (P=0.003) and higher mortality (hazards ratio=1.88; 95% confidence interval, 1.48-2.38) than those without diabetes. Cognitive decline and mortality were similar for those with new-onset diabetes and those without diabetes. For a typical person, 3MS...
