Personalised Prevention of Falls in Persons with Dementia—A Registry-Based Study
Abstract
1. Introduction
2. Materials and Methods
2.1. Data Materials
2.2. Methods
2.3. Variables
2.3.1. Person Characteristics
- Sex (male/female); age (years).
- Physical activity. Easy and strenuous activities were registered, and a physical activity score was calculated as 0–8.
2.3.2. Medical History and Cognitive Functions
- Depression. Depression in dementia was measured using the Cornell scale, scoring 0–38. Scores ≥12 indicate moderate–severe depression [16]. Cornell measures not only depression but also a range of neuropsychiatric symptoms.
- Cognitive fluctuations. The MAYO Fluctuation Composite Scale, scoring 0–4, was used to measure cognitive fluctuations [17]. High scores indicate more fluctuations.
- Drugs. The number of drugs taken regularly was noted and used as a proxy for both comorbidity and side effects of the drugs.
2.3.3. Diagnoses
- Dementia diagnoses: Dementia was classified as Alzheimer’s disease (AD), mixed AD/vascular dementia (MixADVD), vascular dementia (VD), frontotemporal dementia (FTD), or dementia with Lewy bodies (DLB). The diagnosis of FTD was according to Neary et al. [23], and DLB was diagnosed according to McKeith et al. [24]. The ICD-10 criteria (the 10th revision of the International Statistical Classification of Diseases and Related Health Problems) were used for the other diagnoses. According to ICD-10 F 00.2, the diagnosis of MixADVD was applied to persons with features of both AD and VD.
