Chronic obstructive pulmonary disease patients may be at greater risk for mild cognitive impairment, particularly the type that is unrelated to memory, a new study suggests. Of 1,425 participants ages 70 to 89 with normal cognition who were followed for an average of 5.1 years, 171 patients had likely COPD at baseline, and they faced a higher risk of nonamnestic MCI, but there was no elevation of amnestic MCI risk, which can progress to Alzheimer's disease. Study details appear in JAMA Neurology.
