    Abstract Objective: Lumbar puncture (LP) is increasingly common in Alzheimer disease research; however, agreement to undergo LP varies. We sought to determine factors influencing LP consent at Alzheimer's Disease Centers (ADCs) in the United States.
    Methods: A 3-part survey was distributed to each ADC: (1) ADC LP Experience; (2) LP Requestor Experience; and (3) Patient LP Experience (both Initial and Follow-up). In all, 64 LP Requestor, 579 Patient/Initial, and 404 Patient/Follow-up surveys were collected. Logistic regression analyses with generalized estimating equations were used to assess factors associated with LP agreement and post-LP complications.
    Results: Asians and those viewing LP negatively were less likely to agree to LP. Three hundred fifty-two participants had an LP; LP headache occurred in 11.9% (blood patch required in 1.4%) and 9.9% reported other complications. Younger individuals, women, those diagnosed with mild cognitive impairment, use of a Quincke needle, ≤20 mL cerebrospinal fluid drawn, and hemorrhage during LP were associated with LP headache. Use of gravity flow during LP was associated with fewer other complications (nausea, dizziness, vasovagal response, back pain, neck stiffness, and/or nerve root pain).
    Conclusions: LP in Alzheimer disease research is generally safe and well tolerated. Factors influencing LP agreement potentially could be studied to advance participant acceptance of the procedure.

    Abstract Background: The recent development of a national Alzheimer's disease database makes it possible to compare the course of illness in various ethnic groups.
    Methods: The National Alzheimer's Coordinating Center database was used to compare the clinical presentation and course of Alzheimer's disease (AD) in American Indians with whites and African-Americans, and to compare findings in American Indians seen in Oklahoma with those seen elsewhere. We ascertained the diagnosis of probable and possible AD, gender, education, history of affected first-degree relative, depression, history of stroke, Parkinson symptoms, age at onset of dementia, initial visit, and death. We also ascertained years from symptom onset and initial evaluation to death, initial Mini-Mental State Exam (MMSE) score adjusted for education, and years from onset of symptoms.
    Results: Data from 30,993 subjects were analyzed. There were statistically significant but only small differences between groups. American Indians had the lowest proportion of affected first-degree relatives, depression, and extrapyramidal symptoms. Whites had the highest proportion of subjects with affected first-degree relatives and depression, but the lowest history of stroke. African Americans had the most frequent history of stroke and extrapyramidal symptoms. Indians seen in Oklahoma had a lower proportion of affected first-degree relatives than did those seen elsewhere.
    Conclusions: Although there were no clinically significant differences in course of illness between these self-identified ethnic groups, this finding with regard to American Indians must be interpreted with caution, because the subjects for whom we had information regarding ancestry reported a smaller proportion of American Indian (25%) than white (75%) heritage.

    Abstract Importance: It is unclear whether female carriers of the apolipoprotein E (APOE) ε4 allele are at greater risk of developing Alzheimer disease (AD) than men, and the sex-dependent association of mild cognitive impairment (MCI) and APOE has not been established.
    Objective: To determine how sex and APOE genotype affect the risks for developing MCI and AD.
    Data sources: Twenty-seven independent research studies in the Global Alzheimer's Association Interactive Network with data on nearly 58 000 participants.
    Study selection: Non-Hispanic white individuals with clinical diagnostic and APOE genotype data.
    Data extraction and synthesis: Homogeneous data sets were pooled in case-control analyses, and logistic regression models were used to compute risks.
    Main outcomes and measures: Age-adjusted odds ratios (ORs) and 95% confidence intervals for developing MCI and AD were calculated for men and women across APOE genotypes.
    Results: Participants were men and women between ages 55 and 85 years. Across data sets most participants were white, and for many participants, racial/ethnic information was either not collected or not known. Men (OR, 3.09; 95% CI, 2.79-3.42) and women (OR, 3.31; CI, 3.03-3.61) with the APOE ε3/ε4 genotype from ages 55 to 85 years did not show a difference in AD risk; however, women had an increased risk compared with men between the ages of 65 and 75 years (women, OR, 4.37; 95% CI, 3.82-5.00; men, OR, 3.14; 95% CI, 2.68-3.67; P = .002). Men with APOE ε3/ε4 had an increased risk of AD compared with men with APOE ε3/ε3. The APOE ε2/ε3 genotype conferred a protective effect on women (OR, 0.51; 95% CI, 0.43-0.61) decreasing their risk of AD more (P value = .01) than men (OR, 0.71; 95% CI, 0.60-0.85). There was no difference between men with APOE ε3/ε4 (OR, 1.55; 95% CI, 1.36-1.76) and women (OR, 1.60; 95% CI, 1.43-1.81) in their risk of developing MCI between the ages of 55 and 85 years, but women had an increased risk between 55 and 70 years (women, OR, 1.43; 95% CI, 1.19-1.73; men, OR, 1.07; 95% CI, 0.87-1.30; P = .05). There were no significant differences between men and women in their risks for converting from MCI to AD between the ages of 55 and 85 years. Individuals with APOE ε4/ε4 showed increased risks vs individuals with ε3/ε4, but no significant differences between men and women with ε4/ε4 were seen.
    Conclusions and relevance: Contrary to long-standing views, men and women with the APOE ε3/ε4 genotype have nearly the same odds of developing AD from age 55 to 85 years, but women have an increased risk at younger ages.

    Abstract Introduction: In 2015, the US Alzheimer's Disease Centers (ADC) implemented Version 3 of the Uniform Data Set (UDS). This paper describes the history of Version 3 development and the UDS data that are freely available to researchers.
    Methods: UDS Version 3 was developed after years of coordination between the National Institute on Aging-appointed Clinical Task Force (CTF), clinicians from ∼30 ADCs, and the National Alzheimer's Coordinating Center (NACC). The CTF recognized the need for updates to align with the state of the science in dementia research, while being flexible to the diverse needs and diseases studied at the ADCs. Version 3 also developed a nonproprietary neuropsychological battery.
    Results: This paper focuses on the substantial Version 3 changes to the UDS forms related to clinical diagnosis and characterization of clinical symptoms to match updated consensus-based diagnostic criteria. Between March 2015 and March 2018, 4820 participants were enrolled using UDS Version 3. Longitudinal data were available for 25,337 of the 37,568 total participants using all UDS versions.
    Discussion: The results from utilization of the UDS highlight the possibility for numerous research institutions to successfully collaborate, produce, and use standardized data collection instruments for over a decade.

    Abstract The Consortium to Establish a Registry for Alzheimer's Disease (CERAD) was funded in 1986 by the National Institute on Aging to develop standardized assessments for patients with Alzheimer's disease (AD). Since that time, CERAD has developed and evaluated clinical and neuropsychological test batteries, a neuroimaging protocol, and an assessment of the neuropathological findings of the brains of these patients at autopsy. Approximately 1,200 carefully screened patients with AD and 450 control subjects were evaluated using these instruments at 24 major medical centers around the United States. Annual follow-up observations of these subjects were made for up to eight years. Autopsy examinations of the brain were done in over half of the deceased cases and the clinical diagnosis of AD was confirmed in 85 percent of them. This article outlines the procedures used for identifying the clinical sites, the entry and annual evaluations of patients and control subjects, the collection and analysis of data at a central Methodology and Data Management Center, and evaluation of the CERAD measures. We also present selected data from the 50 or so peer-reviewed papers published to date, with particular emphasis on findings from African-American patients with AD, and related policy implications.

    Abstract Although autopsy rates in the United States have been decreasing steadily, the necessity for brain autopsy to confirm Alzheimer's disease (AD) remains. Of 308 consecutively deceased AD patients at 24 CERAD (Consortium to Establish a Registry for Alzheimer's Disease) sites, 167 (54%) were autopsied; 141 (46%) were not. The autopsied and nonautopsied groups were comparable in gender (men, 57.5% versus 49.7%), marital status (married, 69.3% versus 67.1%), age at entry (73 versus 74 years), age at death (76 versus 77 years), and stage of disease at entry (mild, 46% versus 43%). However, the autopsied patients were significantly more likely to be white (94.5% versus 82.1%), to be better educated (13.1 versus 11.3 years), to have been in the study longer (mean, 3.3 versus 2.6 years), and to have had longer total duration of AD (8.1 versus 6.7 years). Of the 24 CERAD sites, 13 stressed the importance of autopsy by dedicating a staff member to seek autopsy and by providing free autopsy and transportation; 11 did not. Logistic regression analysis showed that white race (odds ratio [OR] = 2.74; 95% confidence interval [CI] = 1.10-6.83), increased education (OR = 1.12; 95% CI = 1.04-1.21), and emphasis on autopsy (OR = 4.69; 95% CI = 2.67-8.25) were the only significant factors. Although race and education were important, autopsy was more likely to be obtained when sites dedicated resources to this endeavor.

    Abstract We studied the frequency, severity, and clinical correlations of cerebral amyloid angiopathy (CAA) in 117 CERAD subjects with autopsy-confirmed AD. Eighty-three percent showed at least a mild degree of amyloid angiopathy. Thirty of 117 brains (25.6%) showed moderate to severe CAA affecting the cerebral vessels in one or more cortical regions. These brains also showed a significantly higher frequency of hemorrhages or ischemic lesions than those of subjects with little or no amyloid angiopathy (43.3% versus 23.0%; odds ratio = 2.6, 95% CI = 1.1 to 6.2) High CAA scores also correlated with the presence of cerebral arteriosclerosis and with older age at onset of dementia. Our findings suggest that factors contributing to non-AD-related vascular pathology (e.g., atherosclerosis) may play a role in amyloid deposition in cerebral vessels in AD.

    Abstract Little information exists on the performance of black versus white patients with Alzheimer's disease on neuropsychological tests for dementia. In this study, we compared performance on the CERAD (Consortium to Establish a Registry for Alzheimer's Disease) neuropsychological battery between white (n = 830) and black (n = 158) patients with Alzheimer's disease enrolled in the CERAD study at 23 university medical centers in the United States. The black patients were older, had fewer years of formal education, and were more impaired in their activities of daily living than were the white patients. After controlling for these characteristics and for duration of the disease and severity of dementia, there were differences in the performance of black and white patients on several of the cognitive measures. Black patients scored lower than whites on tests of visual naming and constructional praxis and on the Mini-Mental State Examination. There were no statistical differences in performance on tests of fluency and word list memory. These findings suggest that cultural or experiential differences may modify performance on specific neuropsychological tests. These factors, in addition to age and educational background, should be considered when interpreting performance on neuropsychological tests in elderly black patients with dementia.

    Abstract The neuropsychological tests developed for the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) are currently used to measure cognitive impairments of Alzheimer's disease (AD) in clinical investigations of this disorder. This report presents the normative information for the CERAD battery, obtained in a large sample (n = 413) of control subjects (ages 50 to 89) who were enrolled in 23 university medical centers in the United States participating in the CERAD study from 1987 to 1992. We compared separately the performance of subjects with high (> or = 12) and low (< 12) years of formal education. For many of the individual cognitive measures in the highly educated group, we observed significant age and gender effects. Only the praxis measure showed a significant age effect in the low-education group. Delayed recall, when adjusted for amount of material acquired (savings), was relatively unaffected by age, gender, and level of education. Our findings suggest that the savings scores, in particular, may be useful in distinguishing between AD and normal aging.
