Neuropsychiatric Manifestations of Wildfire Exposure

Abstract

Introduction:Wildfires are life threatening incessant fires in thickly vegetated areas that spread extremely rapidly to human habitat and are difficult to control by human force. The impact of wildfires is enormous on population health and causes tremendous financial burden to individuals and communities.Aim:The aim is to understand the potential disease burden secondary to wildfires both at an individual and population level and reflect upon the immediate and delayed neuropsychiatric manifestations of smoke exposure.Methods:Data on wildfires associated direct and indirect costs on individual health and health care delivery appears to be scant. The effort of this presentation is to present the federal data from 2012 to 2016 on nationwide wildfires, estimated acreage consumed in wildfires, the population exposed, and deaths. Information was extracted from the National Interagency Fire Center, the United States Fire Administration, and the Federal Emergency Management Agency. Through literature review on neuropsychological sequelae of wildfires smoke inhalation and associated trauma, the goal is to reflect upon potential healthcare burden secondary to neuropsychiatric manifestations.Results:Per National Center for Health Statistics, the national fire death rates from 2012 to 2016 ranged 10 to 11 per million population each year, and the property loss both residential and non-residential was estimated at 9 to 10 billion dollars each year. We know healthcare cost is expensive in the United States, and with the stated estimates, one can only envision the health care and public health system burden.Discussion:The characteristic neuropathology of carbon monoxide toxicity is bilateral Globus pallidus necrosis and the common neuropsychological symptoms include fatigue, affective conditions, emotional distress, memory deficits, sleep disturbance, vertigo, dementia, and psychosis. The health effects and associated disability demand policymakers to allocate resources for wildfire prevention/ containment and primary health care providers education, research, and building effective healthcare delivery systems.
