Can prior musical experience benefit frontotemporal dementia patients?

A small study conducted in the United Kingdom has found that individuals with frontotemporal dementia who had engaged in musical activities earlier in life demonstrated superior social and emotional functioning. Those who devoted more time to music listening also exhibited enhanced empathy. The research was published in the Frontiers in Neurology.

Frontotemporal dementia is a group of brain disorders that primarily affect the frontal and temporal lobes of the brain, regions associated with personality, behavior, and language. It is characterized by the degeneration of nerve cells in these areas. Symptoms vary widely between individuals and typically include changes in personality and behavior, such as impulsivity, apathy, and a lack of social awareness. Language difficulties, including problems with speaking, understanding, reading, and writing, are also common.

This type of dementia typically starts between the ages of 40 and 65. Its progression can vary, with some individuals experiencing a rapid decline while others may have a more gradual course. There is currently no cure for frontotemporal dementia, but treatments are available to manage symptoms and improve quality of life.

Behavioral variant frontotemporal dementia (bvFTD) is the most common subtype of frontotemporal dementia, characterized by marked changes in personality and behavior. Individuals with bvFTD may exhibit a lack of empathy, inappropriate social behavior, poor judgment, and a decline in personal hygiene. They may also have difficulty with planning and organizing tasks, and their emotional responses can be blunted or exaggerated. Unlike other forms of dementia, memory is often relatively preserved in the early stages of this disorder.

Study author Jochum J. van‘t Hooft and his colleagues hypothesized that past musical experience might modulate behavioral symptoms of socio-emotional dysfunction in patient with bvFTD independently of the effects on cognitive abilities.

The study involved 14 bvFTD patients from a national tertiary referral center in London. Magnetic resonance imaging scans confirmed the degeneration of brain nerve cells in these individuals. Their average age was 65 years, and on average, they had been living with bvFTD for 6 years.

Participants recounted their past musical endeavors, including instrument playing or singing, and their current music listening habits through a survey. They also undertook an assessment of musical enjoyment (the Barcelona Music Reward Questionnaire) and evaluations of their present musical skills. Assessments of their socio-emotional functioning, neurobehavioral and psychiatric symptoms, and empathy (the Modified Interpersonal Reactivity Index) were provided by the patients’ primary caregivers.

The findings indicated that individuals with a more extensive history of musical engagement were likely to have better social and emotional functioning scores and greater perspective-taking abilities. Those more involved in music also tended to listen to music more frequently at the time of the study and to possess superior musical skills.

Participants who spent more time listening to music weekly were inclined to score higher in empathy. Nonetheless, current musical abilities did not correlate with the social or emotional functioning of these individuals.

The researchers concluded, “Musical experience in earlier life and potentially ongoing regular music listening may ameliorate socio-emotional functioning in bvFTD. Future work in larger cohorts is required to substantiate the robustness of this association, establish its mechanism and evaluate its clinical potential.”

This study presents an intriguing connection between musical engagement and the cognitive function of individuals with dementia. It’s important to note, however, that these observations are based on a small cohort of only 14 participants. Research involving larger and more varied groups may produce different outcomes.
