Introduction/AimAnticholinergic drugs, which have severe central and peripheric side effects, are frequently prescribed to older adults. Increased anticholinergic drug burden is associated with poor physical and cognitive functions. On the other side, the impact of anticholinergics on nutritional status is not elaborated in the literature. Therefore, this study was aimed to investigate the effect of the anticholinergic burden on nutrition.Materials and MethodsPatients who underwent comprehensive geriatric assessment (CGA) 6 months apart were included in the study. Patients diagnosed with dementia were excluded because of the difference in the course of cognition, physical performance and nutrition. Nutritional status and global cognition were evaluated using Mini Nutritional Assessment-short form (MNA-SF), Mini-Mental State Examination (MMSE). Anticholinergic drug burden was assessed with the Drug Burden Index (DBI), enabling a precise dose-related cumulative exposure. Patients were divided into three groups according to DBI score: 0, no DBI exposure; 0–1, low risk; and ≥1, high risk. Regression analysis was performed to show the relationship between the difference in CGA parameters and the change in DBI score at the sixth month.ResultsA total of 423 patients were included in the study. Participants' mean age was 79.40 ± 7.50, and 68.6% were female. The DBI 0 score group has better MMSE and MNA-SF scores and a lower rate of falls, polypharmacy, malnutrition, and risk of malnutrition in the baseline. Having malnutrition or risk of malnutrition is 2.21 times higher for every one-unit increase in DBI score. Additionally, during the 6-month follow-up, increased DBI score was associated with decreased MNA-SF and MMSE score, albumin.ConclusionsThe harmful effects of anticholinergics may be prevented because anticholinergic activity is a potentially reversible factor. Therefore, reducing exposure to drugs with anticholinergic activity has particular importance in geriatric practice.
Objectives Orthostatic hypotension is a well-known disorder, but orthostatic hypertension (OHT) still remains unclear in older adults. The aim of this study was to determine the comparison orthostatic hypotension with OHT according to fall risk and geriatric assessment parameters. Methods A total of 741 patients who were admitted to the geriatric clinic and underwent comprehensive geriatric assessment were reviewed. Orthostatic blood pressure changes were measured by head-up-tilt Table test within the first three minutes. Orthostatic hypotension was defined as 20 or 10-mmHg drop in systolic and/or diastolic blood pressure from supine to standing position. OHT was defined as an increase in systolic blood pressure of 10 mmHg or more while the patient was standing up from the supine position. Results The mean age was 75 ± 8 and 65. About 65% of all participants were female. The rate of orthostatic hypotension and OHT was 17.3 and 7.2%, respectively. The falls and dementia were more frequent, and the Instrumental Activities of Daily Living (IADL) score was lower in orthostatic hypotension group than in OHT and control groups (P < 0.05). These variables were similar between OHT and control groups (P > 0.05). The rates of falls [odds ratio (OR) = 2.02; 95% confidence interval (CI), (0.94–4.33); P = 0.044] and dementia [OR = 2.65; 95% CI, (1.08–6.48); P = 0.032] in orthostatic hypotension group were still higher than in OHT group, even after adjusting for age, sex, estimated glomerular filtration rate and drugs. Conclusion Orthostatic hypotension may be more significant in terms of falls, dementia and impaired IADLs scores in older adults than in OHT and control groups. It seems that OHT may be of no clinical importance in geriatric practice.
Background: It is crucial to evaluate the causes of morbidity and mortality in elderly patients with dementia, such as orthostatic hypotension (OH), which may affect their daily life activities, reduce the quality of life, and increase the caregiver burden. Objective: We aimed to investigate the relationship between OH and the most common subtypes of dementia in detail. Methods: A total of 268 older adults with dementia diagnosed with Alzheimer’s disease (AD), dementia with Lewy bodies (DLB), vascular dementia (VaD), and behavioral variant frontotemporal dementia (bvFTD), and 539 older adults without dementia were included in this prospective study. Comprehensive geriatric assessment including comorbidity, medication evaluation, and the head-up tilt test was also performed. Results: Of the participants, 13.8, 8.3, 6.4, and 4.8% had AD, DLB, bvFTD, and VaD, respectively. After adjusting for age, gender, the presence of comorbidities, and usage of OH-induced drugs; AD, DLB, and VaD were associated with OH (odds ratio [OR]: 2.23 confidence interval [CI] 95% 1.31–3.80; p = 0.003; OR: 3.68 CI 95% 1.98–6.83; p < 0.001, and OR: 3.56 CI 95% 1.46–8.69; p = 0.005, respectively). Furthermore, VaD was independently related to diastolic OH (OR: 4.19 CI 95% 1.66–10.57; p = 0.002), whereas AD and DLB were not. Conclusions: This study shows that elderly patients with DLB, AD, and VaD often have OH, a disabling autonomic dysfunction feature. Moreover, diastolic OH may play a role in the development of VaD. Therefore, considering potential complications of OH, it is essential to evaluate OH in the follow-up and management of those patients.
