A recent study published in the journal "Neurology" said that taking a low dose of aspirin once a day does not reduce the risk of moderate memory disorders, and does not help prevent Alzheimer's disease.
Aspirin has anti-inflammatory properties, and it also helps prevent clots. Doctors prescribe low doses of aspirin to reduce the risk of heart attacks and strokes. However, this product should be used with care, as it can cause bleeding in the brain.
Since aspirin is good for the heart, researchers have hypothesized that it may also be beneficial to the brain, and may reduce the risk of dementia by reducing inflammation and reducing small strokes in the brain.
However, the researchers in that study - which was conducted on a large sample exceeding nineteen thousand people and lasted for a full period of five years - found that a low dose of aspirin per day did not provide any benefit to the participants in the study, whether at the level of inhibiting dementia.
Those results are disappointing, but researchers say that the study period may not have been long enough to demonstrate the potential benefits of aspirin, so the researchers will continue to study its potential long-term effects through follow-up with the study participants.
