In 2020 an unimaginable video went viral. It featured a former ballet dancer named Marta Cinta González Saldaña, affected by extreme Alzheimer’s illness in her senior years. Within the video, Saldaña listens to a bit of music from Tchaikovsky’s Swan Lake and all of the sudden flashes awake starting to maneuver to a dance routine she presumably rehearsed again and again in her youthful days.
A majority of these clips have been shared for years, and so they spotlight the beautiful approach music can rekindle dormant neural pathways in aged topics experiencing critical types of dementia. And whereas music remedy is now a standard follow in nursing properties, little analysis has really zoomed in on the neural mechanisms behind the phenomena, or particularly, what sorts of music might optimize the potential mind advantages.

Editor’s notice: Readers typically ask us for follow-ups on memorable tales. What has occurred to this story over time? This piece was initially revealed in 2022 however has been re-edited and up to date with new data present as of Feb 18, 2025. Take pleasure in!
A 2022 research, led by Psyche Loui from Northeastern College’s Music Imaging and Neural Dynamics Lab, answered two particular questions with regard to this unimaginable music-triggered phenomenon. How does a managed eight-week music remedy program affect the exercise and connectivity between auditory and reward areas of the mind? And, are the useful results of music amplified when the music is self-selected, specializing in songs which might be significantly significant to a person?
To research, the analysis crew recruited a small cohort of cognitively wholesome older adults. At the side of a music therapist, every volunteer created two playlists of music – one dubbed “energizing” and the opposite “stress-free.”
The cohort was tasked with listening to music from their self-selected playlists for one-hour day by day, over the course of eight weeks. The one-hour every day music expertise was designed to be targeted, so every topic was requested to concentrate to their moods, feelings, and recollections whereas listening to their playlists. This wasn’t merely enjoying tunes within the background whereas doing every day chores.
In the beginning and finish of the research, every participant additionally took half in a mind imaging take a look at the place they listened to 24 completely different audio excerpts. Six of these excepts had been self-selected by the participant, whereas the remainder had been different items of music spanning many alternative genres chosen by the researchers.
In a dialog with New Atlas in 2022, Loui defined how her crew’s findings revealed the eight-week music intervention did end in elevated connectivity throughout some key mind areas.
“We noticed adjustments in auditory connectivity to the reward system, particularly the connectivity between the auditory community and the medial prefrontal cortex (which is a part of the reward system) was elevated after intervention,” Loui famous. “We additionally noticed that the fitting govt management community, which incorporates areas which might be necessary for consideration and govt perform, turned extra correct at representing music after the intervention.”
In accordance with Loui, this research was the primary time a music-based intervention had been proven to trigger longitudinal enhancements in connectivity between these explicit mind networks. From a scientific standpoint these findings are thrilling, as decreased connectivity and exercise within the medial prefrontal cortex is seen in a variety of neurodegenerative circumstances, in addition to psychiatric ailments akin to schizophrenia and despair.

The opposite main discovering within the research was that self-selected music was rather more efficient at participating these mind pathways, in comparison with different kinds of extra unfamiliar music. Loui additionally added, the best self-selected music appeared to be songs linked to a participant’s youthful years.
“… we had contributors take heed to about one third self-selected music, and two-thirds researcher-selected music, whereas getting their brains scanned, in order that we might evaluate mind exercise between self-selected and other-selected music, [and] we discovered that self-selected music was rather more efficient at participating the mind,” Loui defined in 2022. “The best music tends to be from adolescent and early maturity for the participant.”
The discovering that the best music for rekindling neural pathways in older age is what was listened to in a single’s youth curiously remembers a big physique of research illustrating how music and cultural style is fundamentally formed in a person’s teenage years. Movie theorist David Bordwell as soon as referred to this phenomena as “the legislation of the adolescent window,” and these mind imaging findings actually affirm that sure neural pathways linked to cultural experiences are actually locked down in these key adolescence.
“Between the ages of 13 and 18, a window opens for every of us,” Bordwell wrote. “The cultural pastimes that appeal to us then, those we discover ourselves drawn to and even obsessive about, will at all times have a strong maintain. We might broaden our tastes as we develop out of these years – we should always, anyhow – however the sports activities, hobbies, books, TV, motion pictures, and music that we beloved then we’ll at all times love.”
A key takeaway from the 2022 research is that there can’t be a one-size-fits-all technique to music remedy, Loui identified. So listening to music you want is necessary, however what this research couldn’t reply is strictly how clinically efficient music remedy could also be as therapy for sufferers with dementia.
… music is an entry key to your reminiscence, your pre-frontal cortex
A study published in 2021 from researchers on the College of Toronto explored the same intervention to Loui’s work, however in Alzheimer’s sufferers with very early-stage cognitive decline. It was a small research, and in contrast the impact between musicians and non-musicians of three-weeks of every day hour-long listening periods with acquainted music.
Whereas mind exercise was barely completely different in these contributors with a historical past of enjoying music, there have been distinct indicators of cognitive enchancment in each teams after three weeks of music remedy. Senior writer on the research Michael Thaut mentioned listening to acquainted music in a single’s senior years may very well be considered a sort of mind gymnasium.
“Whether or not you’re a lifelong musician or have by no means even performed an instrument, music is an entry key to your reminiscence, your pre-frontal cortex,” Thaut said. “It’s easy: hold listening to the music that you just’ve beloved all of your life. Your all-time favourite songs, these items which might be particularly significant to you. Make that your mind gymnasium.”
Extra just lately, a few researchers from USC actually homed in on what occurs within the mind when one listens to nostalgic music. They scanned a variety of folks’s brains in an MRI machine whereas they listened music they beloved, and Sarah Hennessy, one of many researchers, known as the outcomes “superb.”
“Once you hear nostalgic music, there’s exercise throughout your mind, however most notably within the default mode community, which is often lively after we’re daydreaming,” Hennessy said in 2024. “It is usually lively after we’re desirous about our personal narrative. We even have exercise in some visible areas that usually course of what you see in entrance of you. However all these contributors had their eyes closed. So, what is likely to be taking place is that contributors are visualizing what was in entrance of them through the reminiscence the music evoked.”
Loui’s newest research, revealed in October 2024, regarded carefully at how music may help folks deal with sure duties. She discovered sure varieties of music may help folks with consideration difficulties zoom in on a venture. Quick music with no lyrics, she urged, helps focus the mind’s pure rhythmic exercise.
“The mind really oscillates at sure frequencies,” she said recently. “Should you insert these frequencies into the music, that may affect your exercise in those self same frequencies within the mind — we noticed that the mind was very clearly ‘part locking,’ or [working] in time to those amplitude modulations that had been inserted within the music.
The 2022 research was revealed within the journal Scientific Reports.
