About this episode
This episode discusses the link between air pollution and an increased risk of Lewy body dementia, supported by epidemiological data and animal studies.
TWiN explains epidemiological data showing that exposure to air pollution was associated with an increased risk of developing Lewy body dementia, and nasal administration of air pollution in mice led to brain atrophy and impaired cognition and motor function.
