Falling represents a major public health problem among older persons because it leads to premature mortality, loss of independence, and placement in assisted-living facilities. The purpose of this study was to assess the main features and risks for falls among persons older than 65 years of age as well as to quantify their fear of falling. ⋯ The frequency of falls among older people was similar to those in other populations. These results could be used to help select older persons who should be enrolled in fall prevention programmes.

Current diagnostic criteria recommend neuroimaging as a diagnostic support tool for the clinical diagnosis of dementia with Lewy bodies (DLB). Because DLB causes characteristic impairments and disabilities, such as neuroleptic hypersensitivity, which may significantly increase morbidity and mortality, its prompt and correct diagnosis is very important. The aim of this study was to evaluate the extent to which diagnostic accuracy can be increased by using different combinations of brain perfusion single-photon emission computed tomography (bp-SPECT), 123 I-metaiodobenzylguanidine myocardial scintigraphy (MIBG scintigraphy), and DAT-SPECT. Taking finances and patient burden into consideration, we compared the tests to determine priority. ⋯ In terms of stand-alone diagnostic means, priority should be placed on MIBG scintigraphy or DAT-SPECT for the diagnosis of DLB. However, our results suggest that the combination of bp-SPECT, MIBG scintigraphy, and DAT-SPECT increased the accuracy of the clinical diagnosis of DLB.
