Conclusions. Aspirin use, especially current, long-term, and low-dose use, was associated with a decreased risk of depression, anxiety, and stress-related disorders following cancer diagnosis, while the use of non-aspirin NSAIDs was associated with an increased risk, compared with no use of NSAIDs.
Can aspirin reduce brain inflammation?
Because aspirin can be beneficial to the heart, researchers have hypothesized, and smaller previous studies have suggested, that it may also be beneficial to the brain, possibly reducing the risk of dementia by reducing inflammation, minimizing small clots or by preventing the narrowing of blood vessels within the …
Does aspirin relieve stress?
Aspirin can reduce oxidative stress and protect against oxidative damage. Early evidence suggests there are beneficial effects of aspirin in preclinical and clinical studies in mood disorders and schizophrenia, and epidemiological data suggests that high-dose aspirin is associated with a reduced risk of AD.

Does aspirin help dementia?
Daily low-dose aspirin did not reduce the risk of dementia, mild cognitive impairments (MCI) or cognitive decline among healthy older adults without previous cardiovascular events, according to recently published results from the ASPirin in Reducing Events in the Elderly (ASPREE) study.
Can aspirin help vascular dementia?
There is no evidence that aspirin improves the symptoms of vascular dementia. Low-dose aspirin can improve the prognosis of heart disease and stroke, possibly by reducing clot formation within the blood vessels and helping to maintain or improve blood flow to the heart and brain.
