Does auditory rhythmical cueing improve gait in people with Parkinson’s disease and cognitive impairment? A feasibility study

Gait and balance problems resulting from Parkinson’s disease (PD) are more common in people with PD and dementia (PDD), yet, it is unknown whether the benefits of cueing therapy for mobility generalize to them. We aimed to determine the feasibility and effectiveness of auditory cues to improve gait in PD and cognitive impairment (PD-CI). Nine […]

Prevention of dementia by intensive vascular care (PreDIVA): a cluster-randomized trial in progress

Background and Purpose: Cardiovascular risk factors are associated with an increased risk of dementia. Treatment of hypertension and hypercholesterolemia is associated with a decrease in incident dementia. Whether interventions aimed at cardiovascular risk factors in late life also reduce dementia risk is unknown. Here, we report the outline of a pragmatic study that will attempt […]

Addenbrooke’s Cognitive Examination validation in Parkinson’s disease

Background: There is a clear need for brief, sensitive and specific cognitive screening instruments in Parkinson’s disease (PD).; Objectives: To study Addenbrooke’s Cognitive Examination (ACE) validity for cognitive assessment of PD patient’s using the Mattis Dementia Rating Scale (MDRS) as reference method. A specific scale for cognitive evaluation in PD, in this instance the Scales […]

A prospective study of ventriculo-peritoneal shunting for idiopathic normal pressure hydrocephalus

Idiopathic normal pressure hydrocephalus (INPH) is a potentially treatable form of dementia but its diagnosis is difficult and the effectiveness of shunting remains controversial. This study investigates the clinical outcomes of ventriculo-peritoneal shunting in a controlled trial of 33 consecutive patients with INPH. Mean age was 77.2 years (range 58-92 years) and the duration of […]

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 […]

Levodopa use and sleep in patients with dementia with Lewy bodies

Sleep disturbance and excessive daytime somnolence (EDS) are features of Parkinson’s disease (PD) and dementia with Lewy bodies (DLB) that may be influenced by dopamine replacement therapy. The effect of levodopa on sleep and EDS in DLB is unknown and unclear in PD. The aim of this study is to determine if levodopa treatment alters […]

A randomized cross-over study of a traditional Japanese medicine (kampo), yokukansan, in the treatment of the behavioural and psychological symptoms of dementia

The effectiveness and safety of yokukansan (TJ-54), a traditional Japanese medicine (kampo) for the treatment of the behavioural and psychological symptoms of dementia (BPSD), were evaluated in 106 patients diagnosed as having Alzheimer’s disease (AD) (including mixed-type dementia) or dementia with Lewy bodies. Patients were randomly assigned to group A (TJ-54 treatment in period I […]

Donepezil delays progression to AD in MCI subjects with depressive symptoms

Objective: To determine whether the presence of depression predicts higher rate of progression to Alzheimer disease (AD) in patients with amnestic mild cognitive impairment (aMCI) and whether donepezil treatment beneficially affect this relationship.; Methods: The study sample was composed of 756 participants with aMCI from the 3-year, double-blind, placebo-controlled Alzheimer’s Disease Cooperative Study drug trial […]

Vitamin E paradox in Alzheimer’s disease: it does not prevent loss of cognition and may even be detrimental

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. […]

Randomized controlled trial of memantine in dementia associated with Parkinson’s disease

The objective of this study is to investigate the safety and tolerability of memantine, a glutamatergic modulator, in patients suffering from dementia associated with Parkinson’s disease (PDD), an increasingly common complication of PD. This was a 22-week trial of 25 participants with a DSM-IV diagnosis of PDD who were randomized to either placebo or 20 […]
