Ode fragrance device to help people with dementia remain helthy by encouraging them to eat.
‘Ode’ fragrance device has been launched for people with dementia.
The device encourages people with dementia to eat and stay healthy. It blasts scents into the surrounding environment, triggering appetites and improving understanding of a person’s surroundings and time of day.
Ode was created by British design firm, Rodd and fragrance expert Lizzie Olstrum. It releases familiar food scents three times a day, around mealtimes, to encourage people to eat.
Developed in response to the government’s Living Well With Dementia programme, it is hoped Ode will help to address the problem of malnutrition among people with dementia.
Weight loss is a widespread symptom of dementia. Studies in the UK have shown that up to 45% of dementia patients lose significant weight after their diagnosis, and up to 50% do not eat enough food.
Rodd managing director and co-founder, Ben Davies, said: “There are a few reasons for dramatic weight loss and malnutrition in dementia sufferers. First, a dementia diagnosis, often leads to depression. Early on, you’re not feeling great. You’re feeling depressed and confused. The last thing you want to do is concentrate on your diet. That puts a strain on already-overloaded care workers, whether in homes or at residential care facilities. What's more, at the latter, dementia sufferers are often disconnected from the process of making food. The caregivers do not have much time and people become really removed from high-quality, appetising food."
Davies and his colleagues were inspired by research on using fragrances to stimulate reminiscence for patients in care facilities. Ode features bespoke fragrances that are as similar to real food smells as possible. These are divided into three menus of three scents each, including traditional English comfort foods like cherry tart and braised beef casserole.
The three fragrances are easily inserted into the Ode device and last three months. Any fragrances Ode comes up with in the future will be able to fit into this system, so the range of possible fragrances is potentially limitless.
Ode is programmed to release its fragrances in waves by heating up the fragrance, then activating a fan that both blows it out into the air and simultaneously cools the bottle, so it's returned to its original state before being heated again. This way, each ‘alarm’ goes off in waves for at least three hours, so if someone wants to eat at 10am instead of 8am, the scent continues to stimulate their appetite.
Davies said: "The test work we’ve done indicated that about 50% of the people who use it either stabilised their weight or gained weight. That’s incredibly rare.
“Ode is not intended as a medical device, but as a way to augment the other treatments that dementia sufferers receive. Other benefits of the product are more nebulous, like that it can provoke conversations between caregivers and patients around memories and thoughts - something rare and vital for people who tend to be extremely isolated.”
