"Although mild cognitive impairment is clearly a significant risk factor for Alzheimer's disease, the present data suggest that the impact of vascular brain injury should be considered when defining the etiology of mild cognitive impairment," the researchers concluded. And more crucially, "Reductions in cerebrovascular disease may be important in preventing mild cognitive impairment," they asserted.
But previous research has shown that vascular injury and amyloid-plaque buildup aren't the only factors linked with cognitive decline. Data show that smoking may contribute to cognitive decline as well. To read research on that link, see Psychiatric News here. And as researchers learn more about the elements of cognitive decline, they have also discovered an association with hearing loss. Read about that research in Psychiatric News here.
