Vascular risk factors and cognitive function among 3763 participants in the Hypertension in the Very Elderly Trial (HYVET): a cross-sectional analysis
Background: It is well known that the global population is aging and that those over the age of 80 are the fastest growing part of this expansion. Also known is that prevalence of hypertension and cognitive decline both increase with increasing age.; Method: The Hypertension in the Very Elderly Trial (HYVET) was a double blind […]

Results of the open multicenter prospective study of safety and tolerability of rivastigmine (exelon) in different titration regimes in mild and moderate Alzheimer’s disease
Treatment with cholinesterase inhibitors can cause tolerability-related problems in many patients. To facilitate the titration process, rivastigmine, a novel form of the drug (solution), has been elaborated. An objective of the study was to compare efficacy, safety and tolerability of rivastigmine (exelon) used in conventional capsules and/or solution and to assess adherence to this drug […]

Cognitive and psychiatric effects of vitamin B12 replacement in dementia with low serum B12 levels: a nursing home study
Background: The aim of this study is to determine whether B12 replacement would ameliorate cognitive and psychiatric symptoms in elderly subjects with dementia and low serum B12 levels.; Methods: A test group (n = 28) of nursing home residents with low serum B12 levels (300 pg/mL) were evaluated by blinded raters while the test group […]

Methodological improvements in quantifying cognitive change in clinical trials: an example with single-dose administration of donepezil
Objectives: Change in cognitive function in response to a pharmacologic challenge can be observed with greater sensitivity by employing cognitive tests with optimal psychometric properties and a statistical approach that more accurately accounts for individual variability in performance. To demonstrate this approach we examined the cognitive effects of a single acute dose administration of an […]

Lithium trial in Alzheimer’s disease: a randomized, single-blind, placebo-controlled, multicenter 10-week study
Objective: Lithium, a first-line drug for the treatment of bipolar depression, has recently been shown to regulate glycogen synthase kinase-3 (GSK-3), a kinase that is involved in the phosphorylation of the tau protein. Since hyperphosphorylation of tau is a core pathological feature in Alzheimer’s disease, lithium-induced inhibition of GSK-3 activity may have therapeutic effects in […]

Reliability and validity of the telephone version of the Cantonese Mini-mental State Examination (T-CMMSE) when used with elderly patients with and without dementia in Hong Kong
Background: The objectives of this study were to examine the reliability and validity of a 26-point telephone version of the Cantonese Mini-mental State Examination (T-CMMSE) for a sample of 65 elderly patients, comprising 31 patients without dementia and 34 patients with dementia, in an acute regional hospital in Hong Kong, and to identify an optimal […]

A comparison of neurocognitive impairment in younger and older adults with major depression
Background: Neurocognitive impairment is a well-recognized feature of depression that has been reported in younger and older adults. Similar deficits occur with ageing and it is unclear whether the greater deficits in late-life depression are an ageing-related phenomenon or due to a difference in the nature of late-life depression itself. We hypothesized that ageing alone […]

Results of the Trail Making Test among patients suffering from depressive disorders and organic depressive disorders
Aim: Coexistence of depression and dementia for many years has been widely studied for many years. According to the authors for clinical practice, both psychiatric and psychological, it is also important to effectively differentiate between these disease entities. The aim of this study is to compare the implementation of the Trail Making Test (TMT) in […]

Reliability and validity of A Quick Test of Cognitive Speed for detecting early-stage dementia in elderly Japanese
Aim: The aim of this study was to evaluate the reliability and validity of A Quick Test of Cognitive Speed (AQT) for detecting early-stage dementia in the elderly Japanese population.; Methods: A total of 280 clinical participants (180 with mild Alzheimer’s disease, 43 with amnestic mild cognitive impairment, 32 with non-amnestic mild cognitive impairment and […]

The Nottingham Health Profile: a feasible questionnaire for nursing home residents?
Background: The Nottingham Health Profile (NHP) assesses perceived emotional, social, and physical health problems and the extent to which such problems affect daily activities. The objective of our study was to determine the feasibility of the NHP for nursing home residents.; Methods: A prospective multicenter observational study was conducted in 11 nursing homes from April […]
