Mild cognitive impairment (MCI) is a stage of aging that occurs between normal aging and dementia (precedes dementia). Patients with MCI have memory loss who is otherwise functioning normally and does not match the clinical diagnosis criteria for dementia.  MCI is frequently accompanied by cognitive deficits and non-cognitive. One of the most frequent non-cognitive deficiencies is depression. Depression and mild cognitive impairment are closely associate particularly in the elderly and can progress into neurodegenerative disorders like dementia. This indicates that there is a connection that needs to be explored further. Through this review article, a theoretical review of the relationship between MCI with depression and its conversion to dementia.

Rate Of Progression

The spectrum of cognitive decline in the elderly ranges from what can be classified as normal cognitive decline with aging to subjective cognitive impairment to mild cognitive impairment (MCI) to dementia. This article reviewed the up-to-date evidence of MCI including the diagnostic criteria of MCI due to Alzheimer’s disease, vascular cognitive impairment and MCI due to Parkinson disease, management and preventive intervention of MCI. There are various etiologies of MCI, and a large number of studies have been conducted to ascertain the practical modalities of preserving cognition in predementia stages. Lifestyle modification, such as aerobic exercise, is an approved modality to preserve cognitive ability and decrease the rate of progression to dementia, as well as being recommended for frailty prevention.

IntroductionDepression and mild cognitive impairment are common among the elderly. Half the patients with late-life depression also present some degree of cognitive decline, making the distinction between these conditions difficult.ObjectivesTo conduct a database review in order to understand the relationship between these entities, and treatment approaches.AimsTo create and implement clinical guidelines at our institution, to evaluate and treat elderly patients presenting with depression and mild cognitive impairment.MethodsA PubMed database search using as keywords “late life depression”, “depression”; “cognitive impairment”; “mild cognitive impairment” and “dementia” between the year 2008 and 2015.ResultsLate-life depression and cognitive impairment are frequent among the elderly (10–20%). Depression is also common in the early stages of dementia decreasing as the cognitive decline progresses. The causal relationship between these entities is not well understood and some authors advocate a multifactorial model (genetic risk factors; neuroendocrine changes; vascular risk factors) and the cognitive impairment of said changes is dependent on the individual's cognitive reserve. Regarding treatment of depression in patients with cognitive impairment, most authors advocate a stepped approach with watchful waiting and then, if symptoms persist, the introduction of pharmacotherapy and psychosocial intervention.ConclusionsThe relationship between cognitive impairment and depression is still not clear and probably multifactorial. The diagnosis of depressive symptoms in patients with severe cognitive impairment can be difficult and most forms of pharmacological treatment in this population are not beneficial, making it important to carefully evaluate the benefits of introducing new medication.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Introduction: Physical frailty (PF) appears to be associated with low cognitive performance and mild cognitive impairment (MCI). This review evaluated and synthesized the evidence of studies investigating the association between PF and MCI, the prevalence of both conditions and the rate of conversion of healthy older adult to one of them during the follow-up. Methods: A systematic review was performed according to the PRISMA recommendations in the Pubmed, SciELO and LILACS databases. Five studies were eligible according to inclusion and exclusion criteria. Results: Regarding the study design, cross-sectional studies prevailed. Most studies showed a positive association between PF and MCI. Moreover, PF seems to predict a worse cognitive trajectory among participants with MCI and it is associated to a higher risk of developing MCI. Conclusion: Our findings suggest a significant association between PF and MCI. Further longitudinal studies are needed to better explore causality.

The review article describes the characteristics of curable involutive cognitive impairment in the elderly. It is noted that mild cognitive impairment is predominantly neurodynamic in nature, but over time it can transform into a syndrome of moderate cognitive impairment, which, sometimes, is a precursor of dementia. Special attention is given to the clinical manifestations of mild and moderate cognitive impairment, diagnostic criteria, the course of the disease, and its medical and social impact.

ABSTRACT Mild cognitive decline is a feared aspect of aging associated with frailty experienced by individuals. Objective: To determine the number of elderly people with mild cognitive impairment (MCI); to determine the relationship of sociodemographic and clinical variables by group of individuals with or without MCI and to determine the relationship between MCI assessed by 6CIT and the cognitive domains assessed by the MoCA. Methods: A correlational study was conducted of 44 elderly individuals attending a day-care center or residing in a care home, with an average age of 88.9 ± 8.8 years who answered a structured interview collecting sociodemographic and clinical data. Results: The elderly living at home had higher average body mass index and number of pathologies than those living in an institution for the elderly (p < 0.01). 63.6% of the elderly did not have MCI, and no differences were found between residential settings. The comparison between 6CIT and MoCA yielded differences in the general domain and in visual, attention, abstraction and, orientation subdomains. Conclusion: Cognitive stimulation interventions should be optimized according to the residential setting at the level of comorbidities and nutrition.

The Relationship

Many studies have examined the relationship between cognition, and the cingulum and uncinate fasciculus (UF). In this study, diffusion tensor tractography (DTT) was used to investigate the correlation between fractional-anisotropy (FA) values and the number of fibers in the cingulum and UF in patients with and without cognitive impairment. The correlation between cognitive function, and the cingulum and UF was also investigated. Thirty patients (14 males, age = 70.68 ± 7.99 years) were divided into a control group (n = 14) and mild-cognitive-impairment (MCI) group (n = 16). The Seoul Neuropsychological Screening Battery (SNSB) and DTT were performed to assess cognition and bilateral tracts of the cingulum and UF. The relationship between SNSB values and the cingulum and UF was analyzed. The number of fibers in the right cingulum and right UF were significantly different between the two groups. The MCI group showed thinner tracts in both the cingulum and UF compared to the control group. A significant relationship was found between the number of fibers in the right UF and delayed memory recall. In conclusion, memory loss in MCI was associated with a decreased number of fibers in the right UF, while language and visuospatial function were related to the number of fibers in the right cingulum.
