Falls in frontotemporal dementia and related syndromes.

Frontotemporal dementia (FTD) and related diseases are important causes of younger-onset dementia. Falls may be a source of morbidity and mortality in FTD, but remain underreported, and very few high-quality studies have been performed. In this chapter, we briefly review the clinical features of FTD and related syndromes such as motor neuron disease (MND) and atypical parkinsonian syndromes, such as progressive supranuclear palsy (PSP) and corticobasal syndrome (CBS). Falls are frequently encountered in patients who present with FTD syndromes. Although cognitive impairment is associated with falls generally, motor symptoms and signs, as seen in FTD cases that overlap with atypical parkinsonian disorders such as PSP or CBS, or MND, appear to pose the greatest risk. At present, very few systematic studies have been performed to determine the precise frequency, timing, diagnostic implications, and complications of falls in FTD. Further studies are required to understand the scope of this problem, and to develop effective treatments and management strategies.
