“…14,15 A previous CHS study found greater neighborhood greenspace was borderline associated with lower ventricle grade score. 21 Greater neighborhood greenness was associated with greater amygdala integrity 25 and greater cortical thickness in middle-age to older adults, [22][23][24] and multiple gray and white matter regional volumes among children and middle-age to older adults. 26,27 These studies suggest beneficial associations for both greater NSES and greenspace on structural brain health measures.…”

INTRODUCTIONWe examined whether a combined measure of neighborhood greenspace and neighborhood median income was associated with white matter hyperintensity (WMH) and ventricle size changes.METHODSThe sample included 1260 cognitively normal ≥ 65‐year‐olds with two magnetic resonance images (MRI; ≈ 5 years apart). WMH and ventricular size were graded from 0 (least) to 9 (most) abnormal (worsening = increase of ≥1 grade from initial to follow‐up MRI scans). The four‐category neighborhood greenspace–income measure was based on median neighborhood greenspace and income values at initial MRI. Multivariable logistic regression tested associations between neighborhood greenspace–income and MRI measures (worsening vs. not).RESULTSWhite matter grade worsening was more likely for those in lower greenspace–lower income neighborhoods than higher greenspace–higher income neighborhoods (odds ratio = 1.73; 95% confidence interval = 1.19–2.51).DISCUSSIONThe combination of lower neighborhood income and lower greenspace may be a risk factor for worsening white matter grade on MRI. However, findings need to be replicated in more diverse cohorts.HIGHLIGHTS Population‐based cohort of older adults (≥ 65 years) with greenspace and MRI data Combined measure of neighborhood greenspace and neighborhood income at initial MRI MRI outcomes included white matter hyperintensities (WMH) and ventricular size Longitudinal change in MRI outcomes measured approximately 5 years apart Worsening WMH over time more likely for lower greenspace‐lower income neighborhoods

“…Recent studies have studied the neurological effects of residential greenness and reported significant neuroprotective effects, including reduced depression [ 13 ], slower cognitive decline [ 14 ], increased cortical thickness [ 15 ], reduced mortality from neurological diseases [ 11 ], and reduced risk of AD and non-AD dementia [ 12 ]. Although this study provides evidence about the neurological effect of residential greenness based on PD incidence, there is still a dearth of information, requiring further studies to elucidate the effects of greenness on neurological disorders.…”

“…Recently, residential greenness has been widely examined as an emerging environmental factor that reduces various health comorbidities, including neurological diseases [ 10 , 11 , 12 , 13 ]. Good residential greenness has been associated with reduced prevalence of depression [ 13 ], slower cognitive decline [ 14 ], increased cortical thickness [ 15 ], reduced mortality from neurological diseases [ 11 ], and reduced risk of AD and non-AD dementia [ 12 ]. This recent evidence supports the hypothesis that residential greenness could be a neuroprotective factor for PD.…”

It is widely known that exposure to residential greenness is beneficial for health. However, few studies have analyzed the association between greenery and Parkinson’s disease (PD). We selected 313,355 participants who matched the inclusion criteria from the National Health Insurance Service-National Sample Cohort, followed up from 2007 to 2015. Residential greenness, represented by the normalized difference vegetation index (NDVI), was obtained from satellite measurements. We estimated hazard ratios of PD associated with a 0.1-unit increase in long-term greenness exposure at the district level for the previous 1 year of each year until a censoring/event occurred, using time-varying Cox proportional hazard models, adjusted for individual- and area-level characteristics. During the 2,745,389 person-years of follow-up, 2621(0.8%) participants developed PD. Exposure to higher levels of residential greenness was found to be associated with a decreased risk of PD incidence (21% per 0.1-unit increase, 95% confidence interval (CI): 0.74–0.84). In subgroup analyses, stronger protective effects were observed in participants aged over 50 years, females, overweight/obese participants, non-urban residents, non-smokers, alcoholics, and those with comorbidities. Long-term exposure to greenness was beneficial to incident PD, and our findings could aid in the development of public-health strategies.

“…Natural vegetation or green space/greenness surrounding residential and workplaces has been hypothesized to be protective towards dementia [ 16 ]. Potential beneficial effects of greenness on brain structure and function include greater cortical thickness [ 17 , 18 ••, 19 ] and reduced ventricular size [ 20 ]. Research has shown a protective effect of residential greenness for a number of other outcomes including all-cause mortality, obesity, cardiovascular and respiratory diseases, poor sleep quality [ 21 ••, 22 – 29 , 30 ••], pediatric anxiety and depression, and adverse birth outcomes [ 31 , 32 , 33 ••, 34 •, 35 ].…”

Purpose of Review We assessed the relation between environmental greenness and risk of dementia and cognitive impairment, based on a systematic review and meta-analysis up to March 30, 2022, characterizing whenever possible the shape of the association using dose–response meta-analysis. Recent Findings Twelve studies were included in this review, either using normalized difference vegetation index (NDVI) or land use/cover (LU/LC) methodology to assess greenness. Comparing the highest versus lowest exposure categories of greenness assessed using the NDVI (6 studies) or LU/LC (6 studies), we found no association with dementia. Dose–response meta-analysis of the association between greenness measured by LU/LC and dementia, based on only 3 studies, indicated a U-shaped association, but estimates were imprecise. Summary Our systematic review and meta-analysis provided some evidence of a slight inverse association between greenness and dementia at intermediate exposure levels, but not at high levels. Potential methodological limitations, such as exposure misclassification and unmeasured confounding, may have affected the results.
