Forty minutes on a gently vibrating mattress, combined with a nitric oxide pill, could help the brain clear Alzheimer's plaques, according to a study published on November 3, 2026, and shared by The Scientific Report.
The research, led by Vesa Kiviniemi at the University of Oulu in Finland, involved 29 dementia-free adults. During the test, a nitric oxide pill was placed under the tongue, followed by 40 minutes on a gently vibrating mattress, with a second pill taken halfway through.
Blood levels of beta-amyloid 42 rose by 35%
After the session, blood levels of beta-amyloid 42 jumped 35% on average. That protein is the sticky substance behind Alzheimer's plaques. Kiviniemi believes the glymphatic system, the brain's built-in waste network, was flushing it out into the blood, and brain scans showed fluid moving more forcefully through those channels.
In separate analysis, New Scientist reported that additional experiments by Kiviniemi and colleagues tested either only the mattress vibrations or only the nitric oxide pills on the same participants, at least a week before or after the combined approach. Based on brain scans, these solo interventions appeared to have less than half the effect on the glymphatic system than when combined.
Next steps: larger trial planned
Researchers hope to trial the combined approach in 60 people with mild cognitive impairment or Alzheimer's disease next year. Results could follow within two years. New Scientist added that if the trial succeeds, researchers hope to conduct another where a similar group receives the treatment regularly for several months, rather than as a one-off intervention. Kiviniemi said this should be long enough to detect any improvements in cognitive abilities such as memory and problem-solving.
