ABSTRACT
Introduction: The time from symptom debut to assessment of cognitive impairment (TSA) is usually substantial, and many factors can influence the length of this interval. Our objective was to discern whether elevated alcohol consumption is associated with TSA. Methods: Alcohol consumption was measured among 3,236 older Norwegians assessed for cognitive impairment. Elevated consumption was defined as drinking 4-7 times a week. TSA was defined as the number of months between symptom debut and assessment. The association between alcohol consumption and TSA was examined with a multiple regression analysis controlled for sociodemographic and clinical covariates. Results: Mean (SD) and median TSA were 34.8 (35.8) and 24.0 months, respectively. Elevated alcohol consumption was not associated with TSA. Longer TSA was associated with being male, having a high education level, being retired or unemployed, being single, having low scores on the Mini-Mental State Examination (MMSE) or Personal Activities of Daily Living (PADL), having high subsyndrome scores of depression or agitation on The Neuropsychiatric Inventory - Questionnaire (NPI-Q), or having a spouse/cohabitant as the designated next of kin. Conclusion: This study indicates that elevated alcohol consumption does not influence TSA. Possible explanations are discussed, but further research is needed to determine the effect of alcohol definitively. We did identify other novel characteristics associated with TSA which may be important in minimizing the risk of delayed cognitive assessments and should be kept in mind when considering assessment.
ABSTRACT
OBJECTIVES: To explore alcohol consumption among older Norwegian adults with symptoms of cognitive decline, assess the agreement between the reports of older adults and their next of kin regarding a person's alcohol consumption, and explore clinical and sociodemographic variables associated with agreement. METHOD: Alcohol consumption was measured among 3608 older adults consulting specialist health care for symptoms of cognitive decline. Agreement between the participant and their next of kin regarding the participant's alcohol consumption was assessed with a weighted kappa (κ). A logistic regression analysis for hierarchical data was used to explore variables associated with agreement. RESULTS: Both the participants and their next of kin reported that more than 20% of the participants consumed alcohol 1-3 times a week, and that approximately 10% consumed alcohol four or more times a week. The agreement between the participant's and their next of kin's report regarding the participant's alcohol consumption was high (κ = .852), and variables associated with agreement were no cognitive decline, not drinking alcohol during the last year or ever as reported by the participant, and low agitation scores on a psychiatric assessment. CONCLUSION: This paper found alcohol consumption among older adults with symptoms of cognitive decline that was above the national average in Norway. This is also the first paper to demonstrate that a next of kin can be a reliable source of information regarding older adults' alcohol consumption. Health personnel should consider these findings when performing medical assessments or developing interventions for older adults.
