          Abstract

          Purpose

          As an intermediate prodromal stage of dementia, mild cognitive impairment (MCI) causes functional, emotional, and social challenges for both of the person with MCI (PwMCI) and their family caregiver. However, major attention has only been placed on the PwMCI’s for cognitive training. This study evaluated a more comprehensive intervention, which integrated both strength-based and empowerment approaches, to address their complex needs in a dyadic fashion.

          Patients and methods

          This randomized controlled trial allocated 103 MCI patient-caregiver dyads to receive a 14-week dyadic strength-based empowerment program (D-StEP-MCI, n=52) or usual care (n=51). The D-StEP-MCI program consisted of group-based session to the PwMCI, home-based dyadic sessions, and telephone follow-up, with the activities supported the care dyads to navigate their own strengths and resources for integration, together with the trained skills, to optimize role and social engagement in everyday life. Dyadic health outcomes in terms of subjective and objective cognitive function, and neuro-psychiatric symptoms of PwMCI, stress in symptom management of their family caregivers, and depression of the dyads were evaluated at baseline, after the D-StEP-MCI and at 3 months thereafter.

          Results

          By using general estimating equation, the D-StEP-MCI significantly improved the cognitive function, subjective memory, and mood status of the PwMCI, and the positive changes were maintained at the 3-month endpoints. It also has significantly positive effects on caregivers’ stress in symptom management and level of depression.

          Conclusion

          Our findings showed the health benefit of combining strength-based and empowerment approach in supporting the disease adaptation of PwMCI and caregiver in a dyadic fashion. This study also supports the use of a social interaction approach to optimize the everyday engagement of the PwMCI.

          Mild cognitive impairment (MCI) in medical practice: a critical review of the concept and new diagnostic procedure. Report of the MCI Working Group of the European Consortium on Alzheimer's Disease.

          Mild cognitive impairment (MCI) was proposed as a nosological entity referring to elderly people with mild cognitive deficit but no dementia. MCI is a heterogeneous clinical entity with multiple sources of heterogeneity. The concept of MCI was reviewed and a diagnostic procedure with three different stages was proposed by the European Consortium on Alzheimer's Disease Working Group on MCI. Firstly, MCI should correspond to cognitive complaints coming from the patients or their families; the reporting of a relative decline in cognitive functioning during the past year by a patient or informant; cognitive disorders as evidenced by clinical evaluation; absence of major repercussions on daily life; and absence of dementia. These criteria, similar to those defined during an international workshop in Stockholm, make it possible to identify an MCI syndrome, which is the first stage of the diagnostic procedure. Secondly, subtypes of MCI had to be recognised. Finally, the aetiopathogenic subtype could be identified. Identifying patients at a high risk for progression to dementia and establishing more specific and adapted therapeutic strategies at an early stage, together with more structured overall management, is made possible by the diagnostic procedure proposed.

            The Center for Epidemiologic Studies Depression Scale in older Chinese: thresholds for long and short forms.

            No study has examined the diagnostic validity of the Center for Epidemiologic Studies Depression Scale (CES-D) in the Chinese elderly. This study aims to determine appropriate cutoffs for the 20- (CESD-20) as well as a ten-item (CESD-10) version of the instrument. Data were also provided, based on simulated scoring, for the diagnostic performance of the scales when using dichotomous instead of 4-point rating scales. Three hundred and ninety eight persons aged 60 +referred for psychiatric assessment by a physician were administered the CES-D as well as given an independent psychiatric assessment. A spectrum of depression diagnosis as the criterion was used to assess the diagnostic validity of the CES-D. The ten and the 20-item version of the CES-D, regardless of scoring method, produced essentially identical performance indices. The optimal thresholds were 12 and 22 for CESD-10 and CESD-20 respectively, and based on these thresholds, sensitivity, specificity, positive predictive value and negative predictive value were 0.76, 0.55, 0.57 and 0.74 for CESD-10, and 0.75, 0.51, 0.55 and 0.72 for CESD-20. With both ends of the rating scale collapsed to create dichotomous items, the optimal thresholds became 4 for CESD-10 and 7 for CESD-20, and the corresponding performance indices were 0.67, 0.58, 0.56 and 0.69 for CESD-10, and 0.70, 0.58, 0.57 and 0.70 for CESD-20. The ten-item version can be used in lieu of the 20-item version, and a dichotomous response format would probably work as well as the original four-point format, in order to simplify administration for elderly persons.

              Mental Exercise and Mental Aging: Evaluating the Validity of the "Use It or Lose It" Hypothesis.

              It is widely believed that keeping mentally active will prevent age-related mental decline. The primary prediction of this mental-exercise hypothesis is that the rate of age-related decline in measures of cognitive functioning will be less pronounced for people who are more mentally active, or, equivalently, that the cognitive differences among people who vary in level of mental activity will be greater with increased age. Although many training studies, and comparisons involving experts, people in specific occupations, and people whose mental activity levels are determined by their self-reports, have found a positive relation between level of activity and level of cognitive functioning, very few studies have found an interactive effect of age and mental activity on measures of cognitive functioning. Despite the current lack of empirical evidence for the idea that the rate of mental aging is moderated by amount of mental activity, there may be personal benefits to assuming that the mental-exercise hypothesis is true.
