    Efficacy of cognitive-behavioural therapy interventions on reducing burden for caregivers of older adults with a neurocognitive disorder : A systematic review and meta-analysis
    (Taylor & Francis, 2020-10-30) Verreault, Phylicia; Ouellet, Marie-Christine; Turcotte, Valérie; Hudon, Carol; Robichaud, Lye-Ann
    Background: By 2025, 34 million people worldwide will be living with Alzheimer's disease or another form of dementia (i.e., neurocognitive disorders). Symptoms of cognitive disorders include memory deficits and executive deficits; these and other symptoms have functional repercussions on daily activities such as doing chores, taking medication and preparing meals. People with neurocognitive disorders often rely on a caregiver to alleviate the impact of their symptoms, but this help has consequences for the caregiver. Indeed, caregivers report subjective burden, depressive symptoms, stress, anxiety and a lower quality of life than noncaregivers. Multiple cognitive-behavioural therapy (CBT) trials have been conducted to reduce these symptoms for caregivers, and two meta-analyses have suggested that this method could be beneficial in reducing depressive symptoms. However, no meta-analysis has been conducted to evaluate the efficacy of this type of intervention on reducing subjective burden. Method: Eligibility criteria for the individual studies were determined using the PICOS strategy recommended by the PRISMA Statement. Articles were selected from PsycNet, MEDLINE, AgeLine and ProQuest Dissertation and Theses for the period from 2000 to 2017. Article selection, data extraction and bias analysis for individual studies was completed by two independent authors who used a consensus procedure when discrepancies occurred. The statistics Q, df, p value, I-square and Tau-squared were computed. Standardized effect sizes (Hedges’s g) were also computed for all studies. Result: A total of 20 articles were included in the systematic review. Statistics suggested there was no significant heterogeneity, and a fixed-effect model was used. Ten studies (N = 200 caregivers) evaluated the efficacy of CBT in reducing subjective burden, and the meta-analysis suggested a significant reduction in subjective burden following CBT. Additionally, 17 studies (N = 437 caregivers) evaluated the efficacy of CBT in reducing depressive symptoms, and the meta-analysis revealed a significant reduction for these caregivers following CBT. Conclusion: CBT for caregivers of individuals with a neurocognitive disorder was beneficial in reducing subjective burden and depressive symptoms but had no impact on stress, anxiety or quality of life.

    Caregivers’ emotional distress due to neuropsychiatric symptoms of persons with amnestic mild cognitive impairment or Alzheimer’s disease
    (Routledge, 2018-12-27) Ouellet, Marie-Christine; Hudon, Carol; Mavounza, Céline
    Compared to the literature on Alzheimer’s disease (AD), less is known about the emotional distress of caregivers of persons with amnestic Mild Cognitive Impairment (aMCI). This study describes and compares emotional distress due to neuropsychiatric symptoms (NPS) among children and spousal caregivers of aMCI or mild AD care recipients. It also examined the association between the frequency and severity of NPS and caregivers’ emotional distress. In total, 108 spouses or children of persons with aMCI or mild AD were administered the Neuropsychiatric Inventory, measuring the frequency/severity of NPS in the patient as well as the associated caregiver’s emotional distress. Emotional distress due to each NPS was compared between children and spouses and the relationship between NPS and emotional distress was assessed. There was no significant difference in emotional distress between aMCI and mild AD spousal caregivers for all symptoms, but for children caregivers, emotional distress was significantly higher in the mild AD group than in the aMCI group. Regardless of the caregiver’s relationship to the patient or the condition (aMCI vs mild AD) of the latter, there was a positive relationship between the frequency/severity of NPS and caregiver emotional distress. Caregivers of persons with aMCI experienced emotional distress due to the presence of NPS in their significant others at a level that is generally similar to that experienced by caregivers of persons with mild AD. This study highlights the need for interventions to reduce emotional burden by helping caregivers manage NPS in care recipients.
