Language, Music and Dementia (2019-2020)
Dementia is a term that describes a group of symptoms associated with memory loss and impairment of cognitive process severe enough to reduce a person’s ability to perform everyday activities. In the case of most progressive dementias, including Alzheimer’s disease, there is no cure and no treatment that slows or stops its progression. Given the severity of this condition, there is an urgent need for an innovative solution that can delay the onset of dementia symptoms.
Music and language might become a part of such solution. Modern advances in neuroimaging technologies have produced a greater understanding of how musicianship and multilingualism affect the human brain. Duke researchers have developed a new approach that examines dementia using contemporary cognitive neuroscience and neurolinguistics.
This Bass Connections project will explore the impact of musicianship and multilingualism on delaying the behavioral symptoms of dementia. It will become the first scientific effort of its kind to address the interrelationship between languages, music and dementia. The project’s experimental design includes data collection from human subjects through the use of functional magnetic resonance imaging and behavioral data, such as interviews, recordings and language proficiency testing.
The project’s expected outcomes include a better understanding of the neurological interface and mappings of first and second languages; the interrelationship of music and language mappings in the healthy brain; improvements in patient care and wellness in aging populations by using personalized music; and the creation of a database of narratives by musicians (bilingual and monolingual), both healthy subjects and patients.
Team members will participate in one or more of these research efforts. In the future, the project’s findings may be extended to the educational context. Given a connection between music, language and the delayed symptom progression of dementia, educational programs emphasizing music training and language learning will be of increased interest to the general public. Furthermore, the project leaders are committed to fostering a community of young scholars around the issue by offering a course in the spring semester, Language, Music and Dementia: Neuroscience Approaches (NEURO/LIN/MUSIC 595).
