[Fall Risk and Its Management in Parkinson's Disease].

Falls represent critical clinical events in older people, leading to functional decline, fractures, and deterioration in their ability to perform activities of daily living and decreased cognitive abilities, resulting in a bedridden state. Progression of Parkinson's disease (PD) causes postural instability, gait disturbances, gait freezing, and cognitive dysfunction, which markedly elevate the risk of falling compared with that of the general older adult population. Kempster et al. revealed that patients with PD frequently fall, reaching major milestones in PD such as dementia or institutionalization within only a few years; therefore, falls directly influence the prognosis of those with PD. In addition, falls in those with PD are related to not only motor dysfunction but also nonmotor features, including orthostatic hypotension and cognitive decline. Age-related sarcopenia, comorbidities, polypharmacy, and environmental factors further increase the risk of falls; as such, these underlying factors must be understood, and targeted preventive strategies must be implemented for patient management.
