“…To the best of our knowledge, the current study is the first report using the final cohort and their complete follow‐up data. Eligible participants were aged ≥65 years; diagnosed with invasive, nonmetastatic breast cancer; spoke English or Spanish; passed an entry cognitive screen using the Blessed Orientation‐Memory‐Concentration test28; and were within 20 weeks of surgery.…”

BACKGROUNDThe number of survivors of breast cancer aged ≥65 years (“older”) is growing, but to the authors' knowledge, little is known regarding the cognitive outcomes of these individuals.METHODSA cohort of cognitively intact older survivors with nonmetastatic, invasive breast cancer was recruited from 78 sites from 2004 through 2011; approximately 83.7% of the survivors (1280 survivors) completed baseline assessments. Follow‐up data were collected at 6 months and annually for up to 7 years (median, 4.1 years). Cognitive function was self‐reported using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ‐C30); scores ranged from 0 to 100, with a higher score indicating better function. Group‐based trajectory modeling determined trajectories; women were assigned to a trajectory group based on the highest predicted probability of membership. Multinomial logistic regression evaluated the association between receipt of chemotherapy (with or without hormonal treatment) and trajectory group.RESULTSSurvivors were aged 65 to 91 years; approximately 41% received chemotherapy. There were 3 cognitive trajectories: “maintained high” (42.3% of survivors); “phase shift” (50.1% of survivors), with scores slightly below but parallel to maintained high; and “accelerated decline” (7.6% of survivors), with the lowest baseline scores and greatest decline (from 71.7 [standard deviation, 19.8] to 58.3 [standard deviation, 21.9]). The adjusted odds of being in the accelerated decline group (vs the maintained high group) were 2.1 times higher (95% confidence interval, 1.3‐3.5) for survivors who received chemotherapy (with or without hormonal therapy) versus those treated with hormonal therapy alone. Greater comorbidity and frailty also were found to be associated with accelerated decline.CONCLUSIONSTrajectory group analysis demonstrated that the majority of older survivors maintained good long‐term self‐reported cognitive function, and that only a small subset who were exposed to chemotherapy manifested accelerated cognitive decline. Future research is needed to determine factors that place some older survivors at risk of experiencing cognitive decline. Cancer 2016;122:3555–3563. © 2016 American Cancer Society

“…The CDR is derived from a semistructured interview with the participant and a knowledgeable informant. In addition to the interview, the clinician also collects brief performance measures to assess the patient’s cognitive ability including the Mini Mental Status exam [14] (since 1996), the Short Blessed Test [15], abstracting similarities and differences, performing calculations and the Clock Drawing Test [16]. The CDR evaluates cognitive function in each of six categories (memory, orientation, judgment and problem solving, performance in community affairs, home and hobbies, and personal care) without reference to the detailed neuropsychological testing described below or results of previous evaluations.…”

Background: The longitudinal cognitive course in Parkinson’s disease (PD) with and without dementia remains undefined. We compared cross-sectional models of cognition in PD (both with and without dementia), Alzheimer’s disease (AD), and nondemented aging and followed the participants over time. Method: Previously validated models of cognitive performance in AD and nondemented aging were extended to individuals with PD (with dementia, n = 71; without dementia, n = 47). Confirmatory factor analysis and piecewise regression were used to compare the longitudinal course of participants with PD with 191 cognitively healthy subjects and 115 individuals with autopsy-confirmed AD. Results: A factor analytic model with one general factor and three specific factors (verbal memory, visuospatial memory, working memory) fit demented and nondemented PD. Longitudinal change indicated that individuals with PD with dementia declined significantly more rapidly on visuospatial and verbal memory tasks than AD alone. Cognitive declines across all factors in AD and PD dementia accelerated several years prior to clinical dementia diagnosis. Conclusion: Both specific and global cognitive changes are witnessed in PD and AD. Longitudinal profiles of cognitive decline in PD and AD differed. PD with or without dementia has a core feature of longitudinal decline in visuospatial abilities.

“…However, items that were not rated highly by clinical experts were rated highly by more than 75% of the client experts and vice versa. For example, the question about "getting ready in the morning" was rated as (Katzman et al, 1983). Sensitivity and specificity of the 6CIT in identifying dementia has been found to be similar to the MMSE (Brooke & Bullock, 1999).…”
