Book Description
I did not observe conclusive evidence of an association between air pollution and cognition in models stratified by APOE-4 status. To my knowledge, this is the largest study to analyze the association of ambient air pollution on cognition and cognitive decline over time in a racially and ethnically diverse sample. These results further support the current evidence on the role of air pollution on accelerated cognitive aging and brain health.

Book Description
As average life-expectancy increases worldwide, there is a heightened public health concern about impaired cognitive function and dementia with advancing age. There are an estimated 10 million new cases of dementia each year and the worldwide prevalence is expected to triple by 2050. Without current effective treatment, research has expanded to identify modifiable risk factors for dementia to promote healthy cognitive aging. Air pollution is a unique modifiable risk factor as levels can be shaped by individual behaviors and population-level environmental policies and regulations. Ambient air pollution is a mixture of particulate matter, gases, and other organic and metallic components. Emerging evidence suggests chronic exposure may affect diseases of the central nervous system, including dementia and cognitive impairment. It is biologically plausible that increased exposure to air pollution can produce a neuroinflammatory response, which in turn can result in structural changes in the brain. Although epidemiologic studies have observed a link among some populations, the causal pathway between air pollution and dementia remains unclear and these studies are subject to specific methodological challenges. The first chapter of this dissertation reviews the epidemiological evidence regarding the relationship between dementia, cognitive impairment, and air pollution and outlines some methodological challenges my research addresses. The second chapter demonstrates different methods to account for competing events in a cohort of older adults in France and provides recommendations for future research in studies of air pollution and dementia. The third chapter examines the causal pathway between air pollution and dementia, evaluating cardiovascular disease as a potential intermediate in a population-based cohort in Ontario, Canada. The fourth chapter expands the generalizability of the current research by examining the relationship between air pollution and cognitive impairment in a US cohort of Hispanic/Latino adults, an understudied ethnic group with well-documented disparities in both air pollution exposure and chronic health outcomes. The final chapter of this dissertation summarizes key findings and highlights future directions to advance epidemiologic research of air pollution and cognitive aging.

Book Description
Cognitive performance is critical to productivity in many occupations and potentially linked to pollution exposure. We evaluate this potentially important relationship by estimating the effect of pollution exposure on standardized test scores among Israeli high school high-stakes tests (2000-2002). Since students take multiple exams on multiple days in the same location after each grade, we can adopt a fixed effects strategy estimating models with city, school, and student fixed effects. We focus on fine particulate matter (PM2.5) and carbon monoxide (CO), which are considered to be two of the most dangerous forms of air pollution. We find that while PM2.5 and CO levels are only weakly correlated with each other, both exhibit a robust negative relationship with test scores. We also find that PM2.5, which is thought to be particularly damaging for asthmatics, has a larger negative impact on groups with higher rates of asthma. For CO, which affects neurological functioning, the effect is more homogenous across demographic groups. Furthermore, we find that exposure to either pollutant is associated with a significant decline in the probability of not receiving a Bagrut certificate, which is required for college entrance in Israel. The results suggest that the gain from improving air quality may be underestimated by a narrow focus on health impacts. Insofar as air pollution may lead to reduced cognitive performance, the consequences of pollution may be relevant for a variety of everyday activities that require mental acuity. Moreover, by temporarily lowering the productivity of human capital, high pollution levels lead to allocative inefficiency as students with lower human capital are assigned a higher rank than their more qualified peers. This may lead to inefficient allocation of workers across occupations, and possibly a less productive workforce.

Book Description
Most people think of Alzheimer’s disease as a condition which predominately affects elderly people, but an increasing amount of evidence indicates that in populations exposed to high concentration of air pollutants, Alzheimer’s disease development and progression can be identified in pediatric and young adulthood ages. Cognitive, olfactory, gait, equilibrium and auditory alterations are seen early, thus the concept of decades-long asymptomatic period prior to clinical cognitive impairment does not apply to the millions of people exposed day in and day out to polluted environments. This book Alzheimer's Disease and Air Pollution – The Development and Progression of a Fatal Disease from Childhood and the Opportunities for Early Prevention is a compilation of work by researchers intent on revealing the links between air pollution and neurodegeneration. The book is divided into 6 sections. It includes a section describing the ways in which air pollution from traffic and tobacco smoke can damage the brain; epidemiological studies establishing a strong link between dementia and particulate matter and ozone; papers explaining the properties of pollution; and works describing the intricate pathways which transform normal neurons into ghost tangles surrounded by a devastated brain. Air pollution is complex; different pollutants, different sizes and shapes and different portals of entry, play different roles, but their capacity to damage neural tissue is abundantly illustrated in this book, which highlights the need for preventive measures to protect the millions of people currently exposed to air pollutants, and the need to ameliorate their harmful effects.

Book Description
More than 3.7 million U.S. service members have participated in operations taking place in the Southwest Asia Theater of Military Operations since 1990. These operations include the 1990-1991 Persian Gulf War, a post-war stabilization period spanning 1992 through September 2001, and the campaigns undertaken in the wake of the September 11, 2001, attacks. Deployment to Iraq, Kuwait, Saudi Arabia, Bahrain, Gulf of Aden, Gulf of Oman, Oman, Qatar, the United Arab Emirates, and Afghanistan exposed service members to a number of airborne hazards, including oil-well fire smoke, emissions from open burn pits, dust and sand suspended in the air, and exhaust from diesel vehicles. The effects of these were compounded by stressors like excessive heat and noise that are inevitable attributes of service in a combat environment. Respiratory Health Effects of Airborne Hazards Exposures in the Southwest Asia Theater of Military Operations reviews the scientific evidence regarding respiratory health outcomes in veterans of the Southwest Asia conflicts and identifies research that could feasibly be conducted to address outstanding questions and generate answers, newly emerging technologies that could aid in these efforts, and organizations that the Veterans Administration might partner with to accomplish this work.
