Objectives

The aim of this study was to investigate the impact of mixed cognitive intervention training using spaced retrieval training, and errorless learning in participants with early onset dementia. This was based on reality orientation therapy for cognitive function, depression, and occupational performance of patients.

Methods

Two early onset vascular dementia patients (> 65 years) with mild or moderate impairment were enrolled in a pre-test - post-test single-subject research design study. Prior to the study, the caregivers were interviewed about meaningful times, people, places, and areas of interest for the participant. A list of individual training words were selected based upon this information, and the participant was instructed to recall them after a 45-second, 90-second, 6-minute, and 12-minute delay. Baseline (3 sessions), intervention (20 sessions), and a second baseline period (3 sessions) were conducted. Activities of daily living were measured, and cognition was measured using the Consortium to Establish a Registry of Alzheimer’s Disease Korean version, whilst depression was measured using the Korean Form Geriatric Depression Scale, and task performance and satisfaction measured by the Canadian Occupational Performance Measure.

Results

After intervention, both participants showed improvements in activities of daily living (ADL), word list memory/recognition, trail making A, occupational performance, and satisfaction improvement, which was clinically significant in 1 participant who also had a reduced score in the scale of depression classifying him as not depressed.

Conclusion

Spaced retrieval training and errorless learning based on reality orientation therapy is an effective intervention in patients with early onset dementia and mild or moderate impairment.

AbstractAbstract PDF
Objectives
We aimed to determine whether serum levels of homocysteine (Hcy) and its biological determinants, folate and vitamin B12, are related to cognitive decline in elderly people.
Methods
The concentrations of total Hcy, folate, and vitamin B12 were measured in serum samples from 424 cognitively normal controls, 382 mild cognitive impairment patients, and 56 dementia patients from Ansan Geriatric cohort. The Consortium to Establish a Registry for Alzheimer’s Disease (CERAD) neuropsychological battery was used to evaluate cognitive functions.
Results
The dementia patients had higher serum Hcy (dementia, 17.6 ± 6.9 μmol/L; control, 12.9 ± 5.0 μmol/L; p < 0.001) and lower serum folate (dementia, 7.9 ± 4.8 ng/mL; control, 10.0 ± 7.1 ng/mL; p = 0.034) levels compared with controls. There was an inverse relationship between Hcy levels and serum folate or vitamin B12 concentrations. The cognitive status as measured by the (CERAD) score was inversely related to Hcy levels. The adjusted odds ratio of dementia was 5.18 (95% confidence interval: 1.91–14.10; p = 0.001) for moderate (30 ≥ Hcy > 15) hyperhomocysteinemia compared with normal Hcy levels (≤15 μmol/L). In addition, there was weak association between low serum folate (<3.0 ng/mL) and the risk for dementia (crude odds ratio = 3.68; 95% confidence interval: 1.07–12.69; p = 0.039).
Conclusion
Elevated serum Hcy and decreased serum folate concentrations are associated with the risk of dementia in Korean elders.
