- Delirium on the day of admission to general internal medicine wards was studied in 400 consecutive patients aged 70 years and above regarding occurrence, associated factors, clinical profile, length of hospital stay, and mortality. The patients were assessed using the Organic Brain Syndrome Scale and the Mini-Mental State Examination, and delirium was diagnosed according to Diagnostic and Statistical Manual of Mental Disorders (4th ed) criteria. Delirium on the day of admission occurred in 31.3% of the patients and was independently associated with old age, fever on the day of admission (≥ 38°C), treatment with neuroleptics, impaired vision, male sex, and previous stroke. Delirious patients had longer hospital stay (15.4 vs 9.5 days, P < .001), a higher mortality rate during hospitalization (11/125 vs 5/275, P < .001), and a higher 1-year mortality rate (45/125 vs 55/275, P = .001). Delirium is a common complication with often easily identified causes, and it has a serious impact on outcome for older medical patients.

- Clinical profiles of delirium in 717 older people with and without dementia age 75 years and older in 4 different types of care were studied. Delirium and dementia were diagnosed according to DSM-IV criteria. Delirious demented participants (n = 135) had more often had previous delirium episodes and were more often being treated with analgesics compared to delirious participants without dementia (n = 180). The clinical profile of delirium in the participants with dementia was more frequently characterized by aggressivity, latency in reaction to verbal stimuli, restlessness and agitation, delusions, anxiousness, hallucinations, and a poorer orientation and recognition. Delirium among demented participants more often had a fluctuating course during the day and was more common in the evening and at night. In conclusion, clinical profiles of delirium in participants with and without dementia are different, which might indicate a different etiology or pathophysiology, or both, and a need for different treatment strategies.

- Although mild cognitive impairment and dementia are common and have important clinical consequences for patients with Parkinson’s disease (PD) and their caregivers, it is still unclear whether cognitive symptoms may predict the development of dementia in PD patients. The objective of this study was to determine whether cognitive deficits in nondemented PD patients predicted the development of dementia 4 years later. A total of 76 nondemented PD patients from an epidemiological study of PD in the county of Rogaland, Norway, were assessed at baseline and 4 years later with neurological, psychiatric, and neuropsychological evaluations. Twenty-five (42%) new cases of dementia were diagnosed after 4 years. Time to complete the third card of the Stroop test was the only variable that was independently associated with dementia. The authors concluded that poor performance on a test sensitive to executive dysfunction predicted later development of dementia in PD patients. This finding may have important clinical implications as a marker of subsequent development of dementia.

- Nondemented co-twins of twins who were diagnosed as demented were compared to randomly selected members of normal control twin pairs in which both mem-bers of the pair were nondemented. Nondemented co-twins included 23 monozy-gotic and 62 dizygotic twins; there were 27 normal control twins. Both monozy-gotic and dizygotic nondemented co-twins of dementia cases scored significantly lower than normal control twins on 5 of 10 cognitive tests. Moreover, monozygotic co-twins of dementia cases had a generally lower score profile than dizygotic co-twins of dementia cases did. These findings show that being at greater genetic risk for dementia is reflected in cognitive performance even in the absence of a diagnosis of dementia.

APOE alleles in Parkinson disease and their relationship to cognitive decline: a population-based, longitudinal study

Tidskriftsartikel (refereegranskat)abstract
- Apolipoprotein E gene alleles have been linked to various cardiovascular and neurodegenerative disorders. There have been conflicting reports of associations between Apolipoprotein E alleles and Parkinson disease and Parkinson disease dementia. To investigate the role of Apolipoprotein E alleles in Parkinson disease and Parkinson disease dementia, we have determined Apolipoprotein E genotypes in a group of patients with Parkinson disease (n = 95) and compared them with those of healthy control participants (n = 73). Additionally, in 64 longitudinally followed patients with Parkinson disease, the allele types were correlated to development and progression of dementia and to time from onset of Parkinson disease to dementia using multivariate and survival analyses. The Apolipoprotein E e4e4 genotype was more common in patients with Parkinson disease (7.4%) than in healthy controls (1.4%; P = .03). No significant associations between the Apolipoprotein E genotype and development and progression of dementia or time to dementia were found. More studies with larger Parkinson disease samples are warranted.

- Carriers of expanded alleles of the fragile X mental retardation ( FMR1) gene may display parkinsonism, cognitive decline, and behavioral changes. The authors screened 2 male groups of patients affected with Parkinson's disease (PD) (n = 137). One group (n = 56) was followed longitudinally for up to 12 years. Length of CGG repeats in PD patients was compared with healthy controls (n = 310). In addition, the association of the number of CGG repeats with cognitive decline or hallucinations was studied in the longitudinally followed PD group. The authors found no repeats in the premutation range (55-200 CGG repeats) and no significant difference in the proportion of intermediate-size (41-54 CGG repeats) carriers between the PD and the control groups. Using linear regression, the number of CGG repeats was not related to motor or cognitive progression. However, the marked cognitive decline in 2 patients carrying intermediate-size alleles points to a possible association. More studies with larger PD samples are warranted.

Tidskriftsartikel (refereegranskat)abstract
- This article explores new statistical methodologies for using longitudinal data in the early prediction of Alzheimer’s disease (AD). Specifically, the authors examine some new techniques that allow the joint or “shared” estimation of longitudinal components based on both duration (survival) and quantitative changes (growth curves). These new shared growth-survival parameter models may be used to characterize the declining functions that anticipate the onset of AD. The authors apply these models to data from the Kungsholmen Project, a longitudinal study of aging in Stockholm, Sweden. They examine age-based survival-frailty models for the onset of AD, latent growth-decline curve models for changes in cognition over age, and 3 alternative forms of models for the shared relationships of survival and early cognitive decline. The accuracy and reliability of this approach is considered for a better understanding of the developmental course of AD in these data, including the potential removal of biases due to subject selection.

- The aim of this study was to investigate the influence of cognition on motor function using 2 simple everyday tasks, talking and walking, in younger subjects with Alzheimer’s disease and mild cognitive impairment. A second aim was to evaluate reliability for the dual-task test Talking While Walking. Walking speed during single and dual task and time change between single and dual task were compared between groups. The test procedure was repeated after 1 week. Subjects with AD had lower walking speed and greater time change between single and dual task compared with healthy controls. Reliability for Talking While Walking was very good. The results show that motor function in combination with a cognitive task, as well as motor function alone, influences subjects with Alzheimer’s disease in a negative way and that decreased walking speed during single- and dual-task performance may be an early symptom in Alzheimer’s disease.
