Falls in Parkinson’s Disease and Lewy Body Dementia

Parkinsonism is common in the aging population and associated with falls and injurious falls. It is most commonly associated with a neurodegenerative disorder linked with Lewy body pathology (Parkinson’s disease or dementia with Lewy bodies), but also is found in vascular parkinsonism, progressive supranuclear palsy and multiple system atrophy. After discussing diagnostic considerations, this chapter reviews risk factors as well as medical, surgical and non-pharmacological approaches to manage falls in Parkinson’s disease and other Lewy body disorders.
