Mild cognitive impairment is a condition characterized by reduced performance in various cognitive domains that include attention, language, and judgement. The study presented analyzed participants diagnosed with MCI to evaluate the neuropsychological correlates of greenness in this population. Greenness is a term used to refer broadly to areas covered by vegetation. The objective was to understand how the exposure to green spaces can impact cognition domains and cognitive decline, adding to the vast field of research on the effects of the environment on health. Patients’ cognitive and behavioral dimensions as well as cognitive decline were assessed through neuropsychological assessments. Greenness was calculated using the normalized difference vegetation index (NDVI) through satellite imaging. The results of this study suggest that high levels of greenness do not present a protective factor for conversion form MCI to dementia and highlight the difficulty that exists in trying to adequately assess exposure to greenness. Indeed, as numerous confounders are present, assessing the effect of greenness alone on neurological health is a challenge. However, this should not constitute a reason to stymie research in this field.
