This study examined the relationship between subjective memory complaints and performance on tests of memory by relatives of patients with probable Alzheimer's disease (AD) and by older adults without a family history of dementia. Relatives of AD patients did not differ significantly from controls either in level of complaint or in performance on neuropsychological tests. However, among relatives of patients with early-onset AD, significant correlations were found between performance on memory tests and self-rated changes in everyday memory. These findings raise the possibility that relatives who have entered the age range in which their parents or siblings developed dementia symptoms are monitoring their memory performance more diligently than relatives of patients whose illness began at much later ages or persons who have no close relatives with AD.

ABSTRACTIntroduction:The relationship between Alzheimer’s Disease (AD) and alcohol addiction is poorly characterized. Arrests for driving under the influence (DUI) can serve as a proxy for alcohol addiction. Therefore, the potential association between DUI and AD could be helpful in understanding the relationship between alcohol abuse and AD.Materials and methods:A retrospective, population-based cohort study using state health and law enforcement data was performed. The study cross-referenced 141,281 South Carolina Alzheimer’s Disease Registry cases with state law enforcement data.Results:Of the 2,882 registry cases (1.4%) found to have a history of at least one DUI arrest, cases were predominantly White (58.7%) and male (77.4%). Results showed a correlation coefficient of 0.7 (p < 0.0001) between the age of first DUI arrest and the age of AD diagnosis. A dose-response relationship between the number of DUIs and age of AD onset was found to exist, where those with a history of DUI arrest were diagnosed an average of 9.1 years earlier, with a further 1.8 years earlier age at diagnosis in those with two or more arrests for DUI. A history of DUI arrest was also found to be negatively associated with survival after diagnosis, with a 10% decreased life expectancy in those with a DUI arrest history.Conclusions:Driving under the influence, a potential indicator of alcohol addiction, is associated with an earlier onset of AD registry diagnosis and shortened survival after diagnosis. This study contributes to the growing body of evidence suggesting that some cases of AD are alcohol related and, possibly, postponable or preventable.

Abstract Understanding individual factors (e.g., personality) associated with self-reported memory problems is important to refine identification of individuals at a higher risk of developing Alzheimer’s disease (AD). Using multilevel modeling, we examined the association of family history of AD and personality traits with self-reported memory problems in older adults (n = 421; 72.21% White; 62.95% female; Mage = 76.69). Results showed that individuals with a family history of AD reported more frequent memory problems and greater one-year memory decline. Similar findings were reported for individuals with higher extraversion scores. Further, older adults with higher neuroticism scores reported greater one- and ten-year memory decline. Neuroticism was positively related to frequency of memory problems, but only among participants with a family history of AD. Findings suggest that higher neuroticism and lower extraversion may increase older adults’ reports of memory problems. Family history of AD may further exacerbate this tendency.

AbstractEpisodic memory decline is one of the earliest symptoms of late-onset Alzheimer’s Disease (AD) and older adults with the apolipoprotein E e4 (+APOE4) genetic risk factor for AD may exhibit altered patterns of memory-related brain activity years prior to initial symptom onset. In the current study we report the baseline episodic memory task fMRI results from the PRe-symptomatic EValuation of Experimental or Novel Treatments for Alzheimer’s Disease (PREVENT-AD) study in Montreal, Canada, in which 327 healthy older adults, within 15 years of the parent’s conversion to AD, were scanned. During the task fMRI protocol volunteers were scanned as they encoded and retrieved object-location spatial source associations. The task was designed to discriminate between brain activity related to successful spatial source recollection and failures in spatial source recollection, with memory for only item (object) memory. Multivariate task-related partial least squares (task PLS) was used to test the hypothesis that +APOE4 adults with a family history of AD would exhibit altered patterns of brain activity in the recollection-related memory network, comprised of medial frontal, parietal and medial temporal cortices, compared to APOE4 non-carriers (-APOE4). We also tested for group differences in the correlation between event-related brain activity and memory performance in +APOE4 compared to -APOE4 adults using behavioral-PLS (B-PLS). We found group similarities in memory performance and in task-related brain activity in the recollection network. However, the B-PLS results indicated there were group differences in brain activity-behavior correlations in ventral occipito-temporal, medial temporal, and medial prefrontal cortices during episodic encoding. These findings are consistent with previous literature on the influence of APOE4 on brain activity and provide new perspective on potential gene-based differences in brain-behavior relationships in people with parental history of AD. Future research should further investigate the potential to distinguish risk of AD development based on memory performance and associated patterns of brain activity.

Behavioral And Psychological Symptoms

Alzheimer's disease (AD) is associated with a substantial reduction in life expectancy, and mortality has long been evaluated as part of the natural history of this progressive disease. Survival time also plays an important role in projecting the future public health costs of AD. There is now considerable evidence linking mortality in AD with the severity of cognitive impairment and the level of disability in common activities of daily living (Bowen et al., 1996; Jagger et al., 1995; Moritz et al., 1997); established predictors of mortality in AD are listed in Table 1. However, the relationship between mortality and other disease characteristics has received less attention.

Three points of interest lie in considering how Alzheimer, and more significantly Perusini, struggled to throw light on the cause of this devastating disease. There is a stimulating possibility that Perusini believed presenile forms of Alzheimer’s disease described the same disease as senile forms. If so this would anticipate current opinion, and reveal Perusini to dissent from Kraepelin. In addition, Perusini may have understood the pathological relationship between neuritic plaques and vascular changes, once more foreseeing the modern view of Alzheimer’s disease. Finally, Perusini and Alzheimer disagreed with Jung's view concerning the relationship between neuropathology and clinical psychiatry. This point highlights the major change occurring at that time from classical neurology to the psychoanalytic era. In his last work (1911) Alzheimer quoted his Italian disciple many times, even speaking of ‘Perusini's cases’ (Perusinischen Fälle). This article is an attempt to change the eponym of Alzheimer’s disease into the Alzheimer-Perusini disease. This is a brief history of a master and his disciple, whose scientific lives were, by events, divided.

To determine predictors of cognitive deterioration, the authors performed baseline and 1- to 5-year follow-up (mean ± SD = 2.5 ± 1.2 years) neuropsychological assessments on 36 persons (mean age ± SD = 62.1 ± 8.0; range = 50 to 81 years) with age-associated memory impairment. Subjects were recruited from a larger group of volunteers, had minimal medical comorbidity, and 25 of them had a family history of Alzheimer's disease. Baseline age and a subjective memory measure indicating reported frequency of mnemonics usage were significant decline predictors. Subjects reporting more frequent mnemonics use at baseline were more likely to show objective cognitive decline at follow-up. Baseline full-scale IQ, educational level, and family history of Alzheimer's disease failed to predict decline. These findings suggest that although age is the strongest decline predictor in some people with age-associated memory impairment, self-perception of memory function may also predict subsequent cognitive loss.

This study explored psychosocial and cognitive predictors of perceived threat of Alzheimer’s disease (AD). Respondents were 1641 adults (mean age: 64.4; 54% female; 82% white) who completed a module in the Health and Retirement Study, a nationally representative survey of adults aged ≥50. Findings show that perceived threat was significantly higher for those aged 50 to 64 ( P < .001) and 65 to 74 ( P < .05) than for those ≥75. Respondents with a family history of AD had significantly greater perceived threat ( P < .001) than those with no experience. Stronger endorsement of the beliefs that stress ( P < .01) or genetics ( P < .01) are important AD risk factors was significantly associated with greater perceived threat, as was having more depressive symptoms ( P < .01), poorer self-rated memory ( P < .01), and lower cognitive function ( P < .01). Personal experience moderated the relationship between perceived threat and 2 variables: age and self-rated memory. Understanding perceived AD threat may inform practice and policies centered on early and accurate diagnosis.

Objective: Amnesia in Alzheimer's disease (AD) appears early and could be caused by encoding deficiency, consolidation dysfunction, and/or impairment in the retrieval of stored memory information. The relationship between AD pathology biomarker β-amyloid and memory dysfunction is unclear.Method: The memory task functional MRI and amyloid PET were simultaneously performed to investigate the relationship between memory performance, memory phase-related functional connectivity, and cortical β-amyloid deposition. We clustered functional networks during memory maintenance and compared network connectivity between groups in each memory phase. Mediation analysis was performed to investigate the mediator between β-amyloid and related cognitive performance.Results: Alzheimer's disease was primarily characterized by decreased functional connectivity in a data-driven network composed of an a priori default mode network, limbic network, and frontoparietal network during the memory maintenance (0.205 vs. 0.236, p = 0.04) and retrieval phase (0.159 vs. 0.183, p = 0.017). Within the network, AD had more regions with reduced connectivity during the retrieval than the maintenance and encoding phases (chi-square p = 0.01 and &lt; 0.001). Furthermore, the global cortical β-amyloid negatively correlated with network connectivity during the memory retrieval phase (R = – 0.247, p = 0.032), with this relationship mediating the effect of cortical β-amyloid on memory performance (average causal mediation effect = – 0.05, p = 0.035).Conclusion: We demonstrated that AD had decreased connectivity in specific networks during the memory retrieval phase. Impaired functional connectivity during memory retrieval mediated the adverse effect of β-amyloid on memory. These findings help to elucidate the involvement of cortical β-amyloid (Aβ) in the memory performance in the early stages of AD.
