How Music Restores Memories After Brain Injury

Researchers use popular music to help people with severe brain injuries recall personal memories

In the first study of its kind, researchers Amee Baird and Séverine Samson investigated how popular music can trigger autobiographical memories in people with severe acquired brain injury (ABI). Published in the journal Neuropsychological Rehabilitation, their preliminary case-series explores music-evoked autobiographical memories (MEAMs) as a potential tool for memory rehabilitation after brain injury.

During the study the researchers played extracts from “Billboard Hot 100” number-one hit songs in random order to five patients. The songs, taken from the patient’s life span from age 5, were also played to a control group of non-injured subjects. All were asked their familiarity with the song, whether they liked it and what memory the song invoked.

The study is small and exploratory in scope, but it marks an important step beyond previous MEAM research that focused mainly on healthy adults or people with Alzheimer’s disease. Baird and Samson tested five patients with severe ABI and compared their responses to those of five healthy control participants. For each participant, the researchers selected number-one songs from the Billboard Hot 100 spanning the individual’s life from age five onward. Short extracts of these familiar popular songs were played in random order.

After each excerpt, participants reported how familiar the song felt, whether they liked it, and whether the snippet prompted a specific autobiographical memory. When a memory was reported, participants described the content, such as the person, people, place, or life period associated with the song, and rated the memory’s emotional valence.

Results showed that MEAMs occurred in both groups at comparable rates. The frequency of reported music-evoked memories among ABI patients ranged from about 38% to 71% of trials, while controls reported MEAMs on roughly 48% to 71% of trials. Only one of the ABI patients produced no MEAMs; counterintuitively, one of the ABI patients produced the highest number of MEAMs across the entire sample. Across both groups most music-evoked memories were social in nature—memories of people, relationships, or particular life periods—and most were rated as positive. Songs that evoked memories were consistently rated as more familiar and more liked than songs that did not evoke memories.

Comparing music prompts to standard verbal cues, the researchers found that music was often more effective than the Autobiographical Memory Interview (AMI) verbal prompts at eliciting memories across different life periods. In short, a higher percentage of life-period memories were triggered by music excerpts than were retrieved using the AMI verbal probes in this sample.

Baird and Samson conclude that music can serve as an effective stimulus for eliciting autobiographical memories and suggest that it may have a role in rehabilitation for people with autobiographical amnesia after ABI. They caution, however, that music-based approaches are likely to be useful only when patients retain a basic capacity for autobiographical recall and when pitch perception is intact. In cases with fundamental deficits in autobiographical memory or severe perceptual impairments, music may not yield the same benefits.

Although preliminary, the findings point to practical implications for memory rehabilitation and therapeutic work. Music is inexpensive, widely available, emotionally salient, and can be personalized to reflect an individual’s life history—features that make it a promising adjunct to clinical interventions aimed at restoring personal memories, identity, and emotional connections after brain injury. The study also highlights how familiar songs can access rich, socially anchored memories that are often missed by standard neuropsychological tests.

The authors call for larger, systematic studies to confirm and extend these early observations. They recommend expanding MEAM research to larger ABI populations and to other neurological groups, as well as conducting more detailed investigations in healthy populations. Such work could clarify how memory, music, and emotion interact, identify which patients are most likely to benefit from music-based interventions, and reveal the neural and cognitive mechanisms behind music’s unique capacity to enhance autobiographical recall.
