There is controversy as to whether vitamin E is beneficial in Alzheimer’s disease (AD). In this study, we tested if vitamin E prevents oxidative stress and loss of cognition in AD. Fifty-seven AD patients were recruited and divided in two groups: placebo or treated with 800 IU of vitamin E per day for six months. […]
Early intervention for mild cognitive impairment: a randomised controlled trial

Phillips, M.,
Storey, E.
Background: Positive effects are reported for memory training for healthy older adults, and yet there is limited information about the benefit of cognitive intervention for older adults with increasing memory difficulties-mild cognitive impairment.; Objective: To investigate the usefulness of an early cognitive intervention for the memory difficulties experienced by people with amnestic mild cognitive impairment.; […]
Delusion symptoms and response to antipsychotic treatment are associated with the 5-HT2A receptor polymorphism (102T/C) in Alzheimer’s disease: a 3-year follow-up longitudinal study

Although the etiology of psychotic symptoms (hallucinations and delusions) in Alzheimer’s disease is still not known, alterations in serotonergic neurotransmission have been proposed. In a 3-year follow-up study, we evaluated the association of serotonin (5-HT) receptor 5-HT2a 102T/C polymorphism (allelic variants CC, CT and TT) with psychotic symptom severity and response to treatment with atypical […]
Cognitive decline from estimated premorbid status predicts neurodegeneration in Alzheimer’s disease
This study investigated the relationship between premorbid and current cognitive function with respect to the clinical features of patients with various types of neurodegeneration in the form of Alzheimer’s disease (AD), mild cognitive impairment (MCI), and subjective cognitive impairment (SCI), as compared with a healthy control group (C). Clinical features (MMSE, cognitive and depressive symptoms), […]
Effect of music on pain for home-dwelling persons with dementia
The purpose of this study was to investigate the effect of music on pain for home-dwelling persons with dementia. A quasiexperimental design was used. Fifteen subjects listened to their preferred music for 30 minutes before peak agitation time, for 2 days per week, followed by no music for 2 weeks. The process was repeated once. […]
Differential effects of global and cerebellar normalization on detection and differentiation of dementia in FDG-PET studies

FDG-PET ([18F]fluorodeoxyglucose positron emission tomography) is frequently used to improve the differential diagnosis of dementia. However, a fundamental methodological issue of the reference area for the intensity normalization procedure is still unsolved. Here, we systematically compared the two most commonly used normalization methods to the cerebral and to the cerebellar metabolic rate for glucose with […]
Sustainability of motor training effects in older people with dementia
Evidence for sustainability of motor training effects in people with dementia is lacking. To examine whether the substantial improvements in motor performance achieved through a three-month specialized, standardized motor training were sustained, the participants of the randomized controlled trial were re-evaluated nine months after training had ceased. As part of a comprehensive study, participants with […]
Cognitive rehabilitation changes memory-related brain activity in people with Alzheimer disease

Yuen, K. S. L.,
Woods, R. T.,
Evans, S. J.,
Parkinson, C. H.,
Rugg, M. D.,
Linden, D. E. J.
Background: People with Alzheimer disease (AD) are capable of new learning when cognitive support is provided, suggesting that there is plasticity even in a degenerating brain. However, it is unclear how a cognition-focused intervention operates on a neural level.; Objective: The present study examined the effects of cognitive rehabilitation (CR) on memory-related brain activation in […]
