Poet Wadsworth Longfellow said "music is the universal language of mankind", and there's growing evidence that he was right. New research shows people with Alzheimer's (老年痴呆) disease often respond to familiar music or song lyrics, even when their memories and ability to participate in conversation may be flagging.

Jonathan Graff-Radford, Doctor of Medicine, explains on The Mayo Clinic website why this may be:" Musical memories are often preserved in Alzheimer's patients because key brain areas linked to musical memory are relatively undamaged by the disease. "

When English senior Ted McDermott was diagnosed with Alzheimer in 2016, his son Simon McDermott found Ted became verbally and physically violent as the disease progressed. Grateful for the resources provided by the Alzheimer's Society, Simon and 80-year-old Ted made videos of their daily car duets (二重唱) for a fundraising ''Singing for the Brain" program in 2019. Truly remarkable, considering that some days Ted didn't recognize Simon.

The songs brought them to the attention of the public. In just a few months their efforts had considerable success on YouTube, raising over &100, 000, and resulting in a contract with Decca Records for 80-year-old Ted. Although Ted has begun to decline a little in the last years, he always remembers the words to his favorite songs and is happy to go with Simon daily in the car to sing. Different music-related programs and projects are offered by the U. K. Alzheimer's Society organizations. These programs are designed for people with Alzheimer to provide mental stimulation in a supportive social environment.

Social engagement and keeping your brain active, along with a healthy diet and exercising, may seem like obvious good habits to follow for your health in general. They've also been proven to be factors in reducing the risk of developing Alzheimer.

It's never too late to start taking care of your body and your brain—so make music appreciation or singing part of the routine of your loved one struggling with Alzheimer. As William Shakespeare said, "If music be the food of love, play on."
