Listening to music can soothe people of any age. The woman above was 108 when the photo was taken.

We have been keeping an eye on the use of music to connect dementia patients to calming memories. (For example, in this post.)

Today we have Robert Booth reporting at the Guardian that when hospital staff in the UK worked with Alzheimer’s patients on a targeted playlist for each person, the results included lowered heart rate and less agitation.

“Trials are under way at an NHS trust to see if an algorithm can curate music playlists to reduce suffering in Alzheimer’s patients as well as in stressed medical staff.

“A test among people with dementia found an algorithm that ‘prescribes’ songs based on listeners’ personal backgrounds and tastes resulted in reductions in heart rate of up to 22%, lowering agitation and distress in some cases.

“[Now] Lancashire teaching hospitals NHS trust is extending trials to medical staff who worked in critical care during Covid to see if it can ease anxiety and stress. It is also planning to test it on recovering critical care patients, needle-phobic children and outpatients coping with chronic pain in the hope of reducing opiate prescriptions.

“The technology operates as a musical ‘drip.’ playing songs to patients and monitoring their heart rates as they listen. … An algorithm allows the software, which is linked to a streaming service like Spotify, to change forthcoming tracks if the prescription doesn’t appear to be working. Its artificial intelligence system assesses the ‘DNA’ of songs, examining 36 different qualities including tempo, timbre, key, time signatures, the amount of syncopation and the lowest notes. Gary Jones, the chief executive of MediMusic, the company developing the software, said these were among the factors that can shape the heart rate and blood pressure response to a track.

“A trial of 25 people with Alzheimer’s aged from their 60s to their 90s conducted at the Lancashire NHS trust has shown some promising results, the trust said. …

Said Dr Jacqueline Twamley, academic research and innovation manager, ‘Some people it doesn’t affect the heart rate at all, but you can see the effect in their facial expressions and in them tapping along. One patient burst out crying. He said the song brought back happy memories and they were happy tears.’ …

“When Twamley tried it, she was surprised to see the algorithm prescribed her songs by Gloria Estefan, the Pretenders, Lionel Richie and Billy Ocean. She is a fan of more raucous bands, including Led Zeppelin, Queens of the Stone Age and the niche progressive rock outfit Porcupine Tree. But it still had an effect.

” ‘I was quite stressed at the beginning of it, but I just felt calm afterwards,’ she said.

“The system aims to select songs that create a gradation in heart rate, starting with something bracing like Tchaikovsky’s 1812 overture and moving towards a lullaby.”
