The relationship of apathy with daily life activities, quality of life and caregiver burden in patients with dementia

Abstract Background Apathy is one of the most common neuropsychiatric symptoms in dementia. The aim of this study is to evaluate apathy and its relationships with activities of daily living, quality of life and caregiver burden in patients with dementia. Method The research was conducted in a descriptive analytic type. The sample consisted of 88 patients with a definite diagnosis of dementia attending outpatient clinic of a university hospital in Istanbul between October 2019‐March 2020 and their family caregivers. Depressive patients (assessed by Cornell Scale) and paid caregivers were not included. Apathy Evaluation Scale‐Clinician (AES‐C) and Informant (AES‐I) Forms, Neuropsychiatric Inventory (NPI), Mini Mental Test (MMSE), Quality of Life in Alzheimer’s Disease Scale (QoL‐AD), Lawton Instrumental (Lawton IADL) and the Katz Activities of Daily Living Scale (Katz ADL) were used for patients and Caregiver Burden Inventory (CBI) was used for caregivers. Results The mean age of the patients was 73.11±11.68, and diagnosis duration was 3.9±3.1 years, 64.8% had Alzheimer’s type dementia and 53.4% (n = 47) had mild‐1 dementia. The mean MMSE score was 16.4±6.6, NPI‐Symptom score was 16.6±13.7, AES‐C score was 52.9±10.2. The QoL‐AD score was 28.8±6.1 in patient evaluation and 27.6±6.4 in caregiver evaluation. The AES‐C scores were correlated with NPI, MMSE, ADL, Cornell, QoL‐AD, and CBI. Apathy was found to be an important predictor of both the patient’s QoL and CBI. Conclusion In dementia patients, apathy was found to be associated with patient’s activities of daily living, quality of life, and caregiver burden. It is recommended that patients be evaluated for apathy.
