| Sumario: | Luciana Mascarenhas Fonseca,1 Melaine Cristina de Oliveira,2 Laura Maria de Figueiredo Ferreira Guilhoto,3,4 Esper Abrao Cavalheiro,3,4 Cássio MC Bottino1 1Old Age Research Group, Department of Psychiatry, 2Institute of Mathematics and Statistics, University of São Paulo, 3Association of Parents and Friends of People with Intellectual Disability of São Paulo, 4Federal University of São Paulo, São Paulo, Brazil Background: Cognitive decline and Alzheimer’s disease often affect older adults with Down syndrome (DS) much earlier than those in the general population. There is also growing evidence of the effects of negative life events on the mental health and behavior of individuals with intellectual disability. However, to our knowledge, this is the first study investigating objective cognitive decline following bereavement in aging individuals with DS.Objective: The objective of this study was to determine whether cognitive decline correlates with bereavement following the recent loss of a caregiver or with behavioral changes in a sample of adult individuals with DS who do not meet the criteria for dementia or depression, using the longitudinal assessment of the Cambridge Cognitive Examination (CAMCOG), together with the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE).Methods: We evaluated 18 subjects at baseline and over a follow-up period of 14–22 months, attempting to determine whether cognitive decline correlates with bereavement following the recent loss of the main caregiver or with behavioral changes (as assessed with the Neuropsychiatric Inventory).Results: The mean rate of change in CAMCOG was -1.83 (standard deviation 4.51). Behavioral changes had a significant direct influence on cognitive decline. When bereavement was accompanied by behavioral changes, the probability of cognitive decline was 87% (odds ratio 3.82). Conclusion: The occurrence of behavioral changes attributed to bereavement following the loss of the primary caregiver significantly increases the probability of cognitive decline in individuals with DS. Longitudinal comparison of the CAMCOG and use of the IQCODE appear to enrich the analysis of cognitive decline in individuals with DS. Further studies involving larger samples are needed in order to corroborate and expand upon our findings, which can have implications for the clinical management of older adults with DS.
