“…10 One factor that was associated with an increase in the risk of falls was a sedentary lifestyle, which could explain the data found in the present study (the risk of falls was considered moderate for the MCI and MID groups and severe for the MOD and SD groups), in which all of the individuals were sedentary. These results are similar to those reported by Hernandez et al, 7 who found that elderly individuals with AD who did not engage in systemized physical activity performed worse in terms of cognitive function, balance and the risk of falls, when compared with elderly individuals with AD who systematically exercised. The same authors concluded that physical activity is important to the maintenance of balance and consequently, a reduction in the risk of falls.…”

“…These data suggest the need for preventative measures that include physical activity for this population. 7 All of the participants who had experienced falls in the previous 12 months were female, corroborating the results of previous studies 10,23,24 which correlated the female gender with a greater risk of falls in old age. This finding has been correlated with the greater fragility of females, in relation to males, as well as the greater prevalence of chronic diseases such as osteoporosis and a greater link to domestic tasks.…”

“…Alterations to any of these systems or their interaction leads to falls. 7 Falls are one of the main health problems faced by the elderly population. Due to their high incidence, they are considered the main cause of morbidity, mortality, decreased independence and a lower quality of life during old age, problems that also affect the lives of caregivers.…”

“…9 Several studies have addressed the correlation between dementia and falls, balance and functionality. However, they usually compare healthy elderly individuals with those who suffer from mild and moderate dementia, 7,10,11 without considering the period prior to dementia known as MCI, or making comparisons with individuals who suffer from severe dementia.…”

Objective: To assess the relationship between cognitive function, balance, risk of falls and functionality in elderly persons with impaired cognitive function and verify if those with mild cognitive impairment had better balance, functionality and a lower risk of falls than those with dementia. Methods: An analytical cross-sectional study of 33 elderly persons of both genders, aged over 60 years, were evaluated using the Mini Mental State Examination (MMSE), Timed Up and Go (TUG) test, Berg Balance Scale (BBS), Clinical Dementia Rating Scale (CDR) and Barthel Index. Four groups were considered: mild cognitive impairment (MCI; n=9), mild dementia (MID; n=12), moderate dementia (MOD; n=7) and severe dementia (SD; n=5). Data comparison was performed by the Mann Whitney U-test and correlation by Spearman's rank Correlation Coefficient, whit a significance level of ( p<0.05). Results: There was a statistically significant difference in the risk of falls and functionality between the MID and MOD groups, functionality between the MOD and SD groups, and balance, functionality and risk of falls between the MID and SD groups. A moderate correlation between MMSE and BBS (r=0.543; p=0.006) was observed in the MCI group, and a moderate negative correlation between p<0.001) and a strong correlation between MMSE and Barthel (r=0.708; p<0.001) were observed in the dementia group. Conclusion: The deterioration in cognitive function was associated with greater impairment of functionality, balance and an increased risk of falls in elderly persons with dementia, compared to elderly subjects with mild cognitive impairment.

“…The MMSE scores ranged from 0 to 30; a lower value indicated a greater degree of cognitive impairment 14 . In the present study and in agreement with the work of Brucki et al 15 , the participants who scored above the cut-off point corresponding to their schooling level minus 1 standard deviation (SD) remained in the study, whereas those who scored below the cut-off point on the MMSE were excluded from the study.…”

| Background: The relationship between aging and increased life expectancy in the overall population likely contributes to a higher frequency rate and incidence of illnesses and functional disabilities. Physical dependence and cognitive impairment might hinder the performance of activities and result in an overload of care duties for the patient's family and the healthcare system. Objective: The aim of this study was to compare the functional and cognitive changes exhibited by the elderly over a 6-month period. Method: This longitudinal and observational study was conducted in a sample of 167 elderly people, who were selected from the database of the Network of Studies on Frailty in Brazilian Elderly, Universidade Federal de Minas Gerais -UFMG. The participants submitted to the Mini Mental State Examination (MMSE), Katz Index, Lawton and Brody's scale and responded to items on Advanced Activities of Daily Living (AADLs). We analyzed the data using multivariate regression models. Results: The participants' functional capacity exhibited reduced performance of specific instrumental activities of daily living (IADLs), p=0.002, and basic activities of daily living (BADLs), p=0.038. Living alone (odds ratio (OR), 2.53; 95% confidence interval (CI), 1.09-5.87) and work status (OR, 2.52; 95% CI, 1.18-5.41) were associated with changes in the IADLs. The scores in the AADL scale (p=0.163) and MMSE (p=0.059) did not exhibit any significant difference during the study period. The participants with better cognitive function were more independent in their performance of AADLs and IADLs. Conclusion: The results depict specific patterns of loss and stability of functional capacity in community-dwelling elderly.Keywords: elderly; activities of daily life; cognition; rehabilitation.

ObjectivesIncreased depression severity has been linked to cognitive impairment (CI). Importantly, CI is a known risk factor for impaired balance and falls. Therefore, this study aims to explore the relationship between CI and neuromuscular functions and secondarily it aims to find out if CI is a potential predictor for neuromuscular functions deficits in depressed elderly.MethodsEighty‐four depressed elderly participated in the study. Assessment for CI symptoms were done using Mini Mental Status Examination (MMSE) in subjects having confirmed depression. Neuromuscular functions such as balance confidence, static and dynamic balance, functional mobility, and fall risk were subjectively assessed using Activities‐specific Balance Confidence (ABC) Scale, Berg Balance Scale (BBS), Timed Up and Go (TUG) Test, and Performance Oriented Mobility Assessment (POMA), respectively.ResultsPearson's analysis revealed that there was moderate positive linear‐correlation between MMSE and BBS (R = 0.382, p = <0.001) and between MMSE and ABC (R = 0.229, p = 0.036*). Further, regression analysis (R2) revealed that MMSE significantly predicted the neuromuscular functions using BBS [F(1, 82) = 14.013, p < 0.001, with an R2 of 0.146] and ABC [F(1, 82) = 4.545, p= 0.036*, with an R2 of 0.053].ConclusionResults of this study points to an impaired CI as a possible factor in development of neuromuscular function impairment in depressed elderly.
