Abstract: The present thesis aims to characterize emotional distress and burden among caregivers of persons in amnestic mild cognitive impairment (aMCI), which is a probable prodromal stage of Alzheimer’s disease (AD). In the first study (Chapter II), the perceived emotional impact of a wide range of neuropsychiatric symptoms (NPS) was compared between children and spousal caregivers of patients with aMCI or AD. The association between the frequency and severity of NPS and caregivers’ emotional distress was also explored, as well as the relationship between age, sex, and caregivers’ emotional distress. The analyses revealed no significant difference in emotional distress between caregivers of persons with aMCI and with AD for all symptoms. The results indicate a similar emotional distress profile in both aMCI and AD spousal caregivers, with depression, anxiety, apathy, and irritability as the prominent symptoms. However, for children caregivers, emotional distress was significantly higher in caregivers of the AD group than those of the aMCI group. Furthermore, regardless of caregivers’ relationship to the patient or the latter’s condition (aMCI vs AD), there was a positive relationship between the frequency/severity of NPS and caregivers’ emotional distress. There was no effect of sex nor age of caregivers on the emotional distress due to NPS. In the second study (Chapter III), objective and subjective burden along with depressive and anxiety symptoms were investigated in spouses of persons with aMCI. The relationships between psychological morbidity, burden, background and context variables (e.g., sex, education, and health problems of caregivers) were also explored. Results suggested that caregivers have both high levels of subjective and objective burden as well as psychological morbidity (anxiety and depression). They provide new health-related care, emotional support and transportation to the care-recipient. Almost half of them experienced subjective burden associated to stress. In the sample, subjective burden of the caregivers predicted the severity of their depressive and anxious symptoms. Furthermore, when considering the background and context variables, the level of education was negatively associated with depression. As a whole, the results of this thesis indicate that children and spousal caregivers of person with aMCI may need or benefit from targeted interventions in order to reduce the emotional burden related to their role.
