NPS are common even in the early stages of AD. NPS were significantly associated with caregiver assessment of the patient's QoL but not with patients' self-assessed QoL. Depression decreases QoL, but may remain unrecognized in AD patients, emphasizing the need for careful and structured assessment of NPS before deciding on the appropriate treatment.

Spouse caregivers with low SOC seem to be a vulnerable group of caregivers. The many negative effects of perceived health accumulate in these caregivers during the very early phases of the caregiving process. Vulnerable caregivers need to be recognized at the time of AD diagnosis so that they can receive psychological support and counselling in addition to prevent morbidity in these caregivers.

Objective: To examine the association between neuropsychiatric symptoms (NPS) with self-and caregiver-rated Quality of Life (QoL) for patients with Alzheimer's disease (AD) during a 5-year follow-up. Methods: The ALSOVA 5-year follow-up study included, at baseline, 236 patients with either very mild (Clinical Dementia Rating Scale (CDR) 0.5), or mild (CDR 1) AD, together with their caregivers from three Finnish hospital districts. QoL was evaluated using patient self-reported, and caregiver-rated, QoL in AD (QoL-AD) scores. NPS were assessed using the Neuropsychiatric Inventory (NPI), and AD severity was evaluated using the CDR, with cognition tested by the mini-mental state examination. The performance of daily activities was assessed using the Alzheimer's Disease Cooperative Study-Activities of Daily Living Inventory. Results: Over the 5-year follow-up period, patient self-reported QoL-AD scores did not change significantly (p = 0.245), despite increases in their NPS. However, caregiver-rated patient QoL-AD scores declined significantly (p ≤ 0.001), as total NPI scores increased during follow-up. No NPS at baseline, and only apathy at follow-up, correlated significantly (p = 0.007) with patient self-rated QoL-AD scores. Caregiver-rated patient QoL-AD scores correlated significantly with most NPS, especially (p ≤ 0.001) apathy, agitation, anxiety, irritability, depression, and delusions at baseline, and delusions, hallucinations, apathy, appetite disturbances, and anxiety during follow-up. Conclusions: Patient rated QoL-AD scores are an unreliable tool with which to evaluate the success of therapy for NPS. Instead, caregiver-rated scores for patients correlated well with NPI scores, and health care professionals in the clinic should preferentially use these.

Well-educated nursing staff are needed in care and nursing homes to provide high-quality care because comprehensive and advanced nurse competence is required to meet the needs of older people.

Diaries can be used as a primary method of data collection in nursing research, as they produce subjective knowledge of the experiences, emotions and meanings associated with caregiving. Their use can result in a high level of motivation, and ability to reflect on life promotes successful writing.
