The influence of dinner music on food intake and symptoms common in dementia such as depressed mood, irritability and restlessness was studied. The study was carried out in a nursing-home ward in Sweden. Soothing music was played as dinner music for weeks, Swedish tunes form the 1920s and 1930s for two weeks and pop music for two weeks. Prior to these periods, there was one week without music, and at the end of the intervention there was a two-week control period. The effects of the intervention were assessed by psychological ratings and by weighing the food helpings. It was found that during all three music periods the patients ate more in total. The difference was particularly significant for the dessert. The staff were thought to be influenced by the music, as they served the patients more food, both main course and dessert, whenever music was played. The patients were less irritable, anxious and depressed during the music periods. The results of the study suggest that dinner music, particularly soothing music, can reduce irritability, fear-panic and depressed mood and can stimulate demented patients in a nursing-home ward into eating more.

Many nursing home patients with dementia suffer from symptoms of agitation (e.g. anxiety, shouting, irritability). This study investigated whether individualized music could be used as a nursing intervention to reduce such symptoms in four patients with severe dementia. The patients were video-recorded during four sessions in four periods, including a control period without music, two periods where individualized music was played, and one period where classical music was played. The recordings were analysed by systematic observations and the Facial Action Coding System. Two patients became calmer during some of the individualized music sessions; one patient remained sitting in her armchair longer, and the other patient stopped shouting. For the two patients who were most affected by dementia, the noticeable effect of music was minimal. If the nursing staff succeed in discovering the music preferences of an individual, individualized music may be an effective nursing intervention to mitigate anxiety and agitation for some patients.

Many patients with dementia symptoms display forms of agitation such as the repeating of words, restlessness and aggression. These forms of behaviour may inflict strain on the co-patients and the caregivers. In this study, 17 experienced formal caregivers from nursing homes and collective residential units were interviewed about their experiences of agitated patients with dementia and strategies to improve their care. The questions were open except for specific questions about sound, music, and opinions about pharmacological treatment. A calm atmosphere and a slow pace emerged as important strategies to control agitation. Fixed routines could develop this. The mixing of lucid and agitated dementia patients appeared as a major problem, because some lucid patients became angry when patients with dementia displayed agitation. Irritability in one patient could trigger agitation in other patients but was possible to stop at an early stage. Several responders had successfully used music to calm individual agitated patients. Music seemed to be an underestimated nursing intervention to control agitation in daily life, but uncontrolled sound could cause agitation in the patients and stress in the nursing staff.

At a nursing home ward for demented patients, selections of dinner music were played during three periods of 2 weeks. At the end of the study was a control period. The reactions of five patients to three different types of music were registered by video observations. This study showed that the patients were affected by music, particularly soothing music. For example, it was found that when music was played one of the study's restless patients became unusually calm whereas another fed herself more than usual. The patients spent more time with dinner when music was played. Dinner music made the patients eat more calmly. Music as a nursing tool is an intervention that is simple to realize and worth trying. A tentative conclusion of this study is that music can beneficially affect restless and agitated demented patients.
