Memory for Music: Effects of individual intensive musical training based on singing in non-musicians with Alzheimer’s disease

This project, called Memory for Music, focuses on the increasing number of people worldwide living with dementia, especially Alzheimer's disease (AD). AD typically starts with memory problems and eventually affects daily activities. Active music interventions, especially singing, have shown positive effects on mood, behavior, and quality of life for people with dementia, but their impact on cognition is not well understood. The project aims to address this gap by studying the effects of learning new songs on cognitive, behavioral, and brain functioning. The study will involve home-dwelling adults aged 65 or older with AD from Argentina, Austria, and Norway. Participants will undergo 5 months of intensive musical training (twice a week) and 5 months of minimal training (once a month) in a random order, with a 2-month break in between. The interventions include learning new songs with a personal music teacher. General cognition will be measured using the Alzheimer's Disease Assessment Scale – Cognitive (ADAS-cog), and memory for music will be assessed through various methods, including behavioral tasks and brain responses (EEG). Mood will also be evaluated in each session. The goal is to include 113 participants to ensure reliable detection of meaningful effects. The study will explore how mood and memory for music contribute to changes in cognitive abilities, and whether these effects vary based on factors such as sex, age, AD stage, or previous musical training and general education. The project emphasizes collaboration between researchers, service providers, and users to ensure the study's relevance and applicability.

The number of people living with dementia is increasing and is high in low, middle, and high-income countries. Alzheimer’s disease (AD), the most common type of dementia, manifests itself initially with cognitive impairment in memory domains, and later affects all activities of daily living. Active music interventions, particularly singing, can help to improve mood, behaviour problems, and quality of life. Too little is known about their effects on cognition, although some promising studies exist. The M4M project aims to fill this gap by measuring effects of learning new songs on clinical, behavioural and brain functioning. Specifically, M4M aims to examine changes in general cognitive functioning and memory for music in non-musician adults with AD undergoing intensive individual musical training based on singing novel songs, compared to minimal training. Home-dwelling adults with AD, 65 years or older, in 3 countries (Argentina, Austria, Norway), will receive 5 months of intensive intervention (2x/week) and 5 months of minimal intervention (1x/month), in random order, with a 2-month break in between. Interventions will entail learning new songs with an individual music teacher. At the end of each intervention period, general cognition will be measured with the Alzheimer's Disease Assessment Scale – Cognitive (ADAS-cog) by a person who is unaware of the intervention received. Memory for music will be tested with observations, behavioural tasks, and brain responses (EEG). Mood will be assessed in each session. We aim to include 113 participants; this will help us to reliably detect clinically meaningful effects. We will also examine how mood and memory for music lead to changes in cognitive abilities, and whether effects depend on sex, age, AD stage, or previous musical training or general education. M4M will be conducted in close collaboration between academic researchers, service providers, and service users to ensure relevance and applicability.
