Cognition in People Aged 80 Years and Older: Determinants and Predictors of Change from a Population-Based Representative Study in Germany.

BACKGROUND: The number of people aged 80 years and older (80+) will increase drastically in the upcoming decades. The preservation of cognitive functions will contribute to their quality of life and independence. OBJECTIVES: To identify determinants of cognition and predictors of change in cognitive performance in the population 80+. DESIGN: Cross-sectional and longitudinal population-based on the representative NRW80+ survey. SETTING: Randomly drawn cases of people aged 80+ from the municipal registration offices, including people living in private homes and institutional settings. PARTICIPANTS: The participants in the cross-sectional sample (N=1503, 65.5%female) were 84.7 years old (95%CI[84.5,85.0]) and had 12.3 years of education (95%CI[12.1,12.4]). The participants in the longitudinal sample (N=840, 62.5%female) were 84.9 years old (95%CI[84.6,85.2]) and had 12.3 years of education (95%CI[12.0,12.5]). MEASUREMENTS: The cognitive screening DemTect, age, sex, education, and social, physical, and cognitive lifestyle activities, as well as subjective general health status and depressive symptoms, were assessed at baseline and 24-month follow-up. RESULTS: Younger age, more years of education, and more cognitive lifestyle activities were identified as the most consistent determinants of both better cognitive performance and preservation of cognitive performance for both global cognition as well as the DemTect subtests on memory and executive functions. CONCLUSIONS: Our findings reveal that commonly investigated determinants of, and change in, cognitive performance are valid for the people 80+ and highlight the importance of cognitive lifestyle activities for cognitive health. The maintenance of cognitive functions is a key aspect of healthy aging in terms of preserving independence in people 80+.

Cognition in older offenders in North Rhine-Westphalia: A comparison of prisoners and patients in forensic psychiatry hospitals.

The number of elderly delinquent individuals living in prisons and forensic hospitals is increasing. For both settings, complex needs have been described for the elderly related to age-related changes and frequent somatic disorders as well as mental disorders, primarily depressive symptoms.. One of the biggest challenges are cognitive impairments which have been described for both groups, probably not least due to frequent risk factors (e.g., substance abuse, depressive symptoms). Given that the group of forensic patients has a manifest mental illness, which is usually treated with psychopharmaceuticals, the question arises as to what extent cognitive deficits are more frequent here. For both groups, the detection of cognitive deficits with regard to therapy and release planning is of relevance. In sum, studies on cognitive function in both populations are rare, and the results are hard to compare due to different instruments to assess cognition. Sociodemographic, health-, and incarceration-related data were collected as well as neuropsychological functions using established instruments to evaluate global cognitive functioning (Mini-Mental State Examination [MMSE], DemTect), executive function (Frontal Assessment Battery [FAB], and Trail Making Test [TMT]). In the final sample, 57 prisoners and 34 forensic inpatients from North Rhine Westphalia, Germany being 60 years and older were included. The groups were comparable in age (prisoners: M = 66.5 years, SD ± 5.3; forensic inpatients: M = 66.8 years, SD ± 7.5) and education (prisoners: M = 11.47, SD ± 2.91; forensic inpatients: M = 11.39, SD ± 3.64), but the offenders in forensic psychiatry had spent significantly more time in the correctional setting than prisoners (prisoners: M = 8.6, SD ± 10.8; forensic inpatients: M = 15.6 years, SD ± 11.9). In both groups cognitive deficits were frequent. Depending on the tests and population, between 42% and 64% showed impairments in global cognition, and between 22% and 70% were classified with impaired executive functioning. We found no significant differences in global cognition or executive functions assessed with the TMT between the two groups. However, forensic inpatients were significantly more impaired in the FAB compared to the prisoners. The results emphasize the high frequency of cognitive dysfunction in both settings and a possibly higher frequency of "frontal" dysfunction in forensic inpatients, and, thus, indicate the relevance of routine neuropsychological diagnostic and treatment procedures in these settings.

[Cognitive Training in Parkinson's Disease - A New Therapy Option?]. / Kognitives Training bei Parkinson-Patienten - eine neue Therapieoption?

Cognitive impairment is a frequent and clinically relevant symptom in patients with Parkinson's disease (PD). Given that pharmacological therapy options are limited, non-pharmacological interventions for the prevention and treatment of cognitive impairment in PD patients are attracting increasing interest. This review summarizes the current state of research regarding cognition-based interventions in PD patients. Eleven randomized controlled studies (RCT) were found in a systematic literature search, all of which used cognitive training (CT). These studies and a recently published meta-analysis demonstrate that especially executive and memory functions can be enhanced by CT in PD patients. Future studies examining CT or cognitive stimulation should include large PD samples with well-defined cognitive inclusion criteria so that clear therapy recommendations can be defined for PD patients without cognitive dysfunctions, those with mild cognitive impairment, and those with dementia.
