Latest shingles vaccine could help delay dementia, study says 02:54
There may be new hope in the fight against dementia , according to recent research that found the latest shingles vaccine appears to delay the onset of the memory-impairing condition.
In the study, published in Nature Medicine on Thursday, researchers found people who got the vaccine lived, on average, an additional 164 days without a dementia diagnosis compared to those who received the previous shingles vaccines.
On "CBS Mornings" Friday , Dr. Céline Gounder, CBS News medical contributor and editor-at-large for public health at KFF Health News, said the results were exciting.
"The fact that we have a vaccine that's already approved, already out there, covered by insurance, super easy to get. The fact that that is showing this kind of level of protection is really promising for a lot," she said.
In an expert reaction shared alongside the study, Dr. Sheona Scales, the director of research at Alzheimer's Research UK, said, "Dementia isn't an inevitable part of aging; it's caused by diseases like Alzheimer's. So finding new ways to reduce people's risk of developing these diseases is vital."
But, it isn't clear how the vaccine might be reducing risk, Scales' comment continued, adding "It will be critical to study this apparent effect further."
The authors also note further research is needed to understand what exactly creates this association.
"I think the real question before us now is, should we be starting to vaccinate even earlier? Will you need more doses if you start vaccinating vaccinating earlier? We don't have answers to that yet," Gounder said.
Preventing dementia later in life involves a lot of the same things experts advise for overall health.
"You want to control your blood pressure, avoid developing diabetes through good diet and exercise, but if you have diabetes, be sure to manage it well, quit smoking," Gounder said.
"Try to minimize your exposure, get some indoor air filtration units. You might want to be wearing a mask outdoors during those periods," Gounder advised.
