“…Because TICS is a brief telephone-administered cognitive assessment, it is not as effective at evaluating cognitive function as clinically administered tests. Although TICS has been validated as a good indicator for pathological cognitive decline with high sensitivity and specificity (Crimmins et al 2011;Crooks et al 2005;Fong et al 2009), this study cannot make strong claims that Alzheimer's disease or other pathological cognitive decline caused low fluid cognition scores.…”

Population aging has driven a spate of recent research on later-life cognitive function. Greater longevity increases the lifetime risk of memory diseases that compromise the cognitive abilities vital to well-being. Alzheimer's disease, thought to be the most common underlying pathology for elders' cognitive dysfunction (Willis and Hakim 2013), is already the sixth leading cause of death in the United States (Alzheimer's Association 2016). Understanding social determinants of pathological cognitive decline is key to crafting interventions, but evidence is inconclusive for how social factors interact over the life course to affect cognitive function. I study whether early-life exposure to the Great Depression is directly associated with later-life cognitive function, influences risky behaviors over the life course, and/or accumulates with other life-course disadvantages. Using growth curve models to analyze the Health and Retirement Study, I find that early-life exposure to the Great Depression is associated with fluid cognition, controlling for intervening factors-evidence for a critical period model. I find little support for a social trajectory model. Disadvantage accumulates over the life course to predict worse cognitive function, providing strong evidence for a cumulative inequality model.

“…The Telephone Interview for Cognitive Status Modified (TICS-m; 12 items; range = 0-50) was administered to assess cognitive function [35][36][37] . The TICS-m has been reported to yield information that is of value for assessment of cognitive impairment and dementia in epidemiologic research [38] . In addition, each subject was asked to provide the name and telephone number of a study partner (informant) who knew them well and would be willing to answer questions about them.…”

Background: The objective of this study was to establish a prospective population-based cohort to investigate the prevalence, incidence and risk factors for mild cognitive impairment (MCI) and dementia. Methods: The Olmsted County, Minn., population, aged 70–89 years on October 1, 2004, was enumerated using the Rochester Epidemiology Project. Eligible subjects were randomly selected and invited to participate. Participants underwent a comprehensive in-person evaluation including the Clinical Dementia Rating Scale, a neurological evaluation and neuropsychological testing. A consensus diagnosis of normal cognition, MCI or dementia was made by a panel using previously published criteria. A subsample of subjects was studied via telephone interview. Results: Four hundred and two subjects with dementia were identified from a detailed review of their medical records but were not contacted. At baseline, we successfully evaluated 703 women aged 70–79 years, 769 women aged 80–89 years, 730 men aged 70–79 years and 517 men aged 80–89 years (total n = 2,719). Among the participants, 2,050 subjects were evaluated in person and 669 via telephone. Conclusions: Strengths of the study are that the subjects were randomly selected from a defined population, the majority of the subjects were examined in person, and MCI was defined using published criteria. Here, we report the design and sampling, participation, baseline measures and sample characteristics.

“…For the purpose of this study, we contacted surviving patients to assess their cognitive abilities using the Telephone Interview for Cognitive Status, modified (TICS-m), a validated tool used to screen for dementia (table 1). 18,19 To minimize bias, we analyzed functional outcome at hospital discharge of patients that we could not reach by telephone. We administered the TICS-m according to published methods 20 and using a standardized script.…”

Cognitive outcomes of patients undergoing therapeutic hypothermia after cardiac arrest

Objective: We aimed to study the long-term cognitive abilities of patients surviving out-of-hospital cardiac arrest who were treated with therapeutic hypothermia (TH). Methods:We prospectively identified and examined consecutive survivors of out-of-hospital cardiac arrest who underwent TH at our institution from June 2006 to May 2011. The results of brain imaging, serum neuron-specific enolase (NSE) measurements, and EEGs were recorded. We assessed cognitive domains using the modified Telephone Interview for Cognitive Status. An education-adjusted score of $32 was considered normal.Results: Of 133 total patients, 77 (58%) were alive at a median follow-up of 20 months (interquartile range 14-24 months). We interviewed 56 patients (73% of those alive). Median age was 67 years (range 24-88 years). Fifty-one patients (91%) were living independently. Modified Telephone Interview for Cognitive Status scores ranged from 16 to 41. Thirty-three (60%) were considered cognitively normal and 22 (40%) were cognitively impaired. The time to assessment did not differ among the cognitive outcomes (p 5 0.557). The median duration of coma was 2 days, possibly indicating that patients with severe anoxic injury were not included. Eighteen patients were not working at the time of their cardiac arrest (17 were retired and 1 was unemployed). Of the 38 patients who were working up to the time of the cardiac arrest, 30 (79%) returned to work. Cognitive outcome was not associated with age, time to return of spontaneous circulation, brain atrophy, or leukoaraiosis. Conclusions:The majority of surviving patients who underwent TH after cardiac arrest in this series had preserved cognitive function and were able to return to work.
