Musical dual-task training in patients with mild-to-moderate dementia: a randomized controlled trial.

ABSTRACT: Background/aims:Dual-task training may improve dual-task gait performance, balance, and cognition in older adults with and without cognitive impairment. Although music has been widely utilized in dementia management, there are no existing protocols for music-based dual-task training. This randomized controlled study developed a Musical Dual-Task Training (MDTT) protocol that patients with dementia can use to practice walking and making music simultaneously, to enhance attention control in patients during dual-tasking. Methods:Twenty-eight adults diagnosed with mild-to-moderate dementia were assigned to the MDTT (n=15) or control groups (n=13). The MDTT group received MDTT, while the control group participated in non-musical cognitive and walking activities. The effects of MDTT were evaluated through the primary outcome of attention control, and secondary outcomes of dual-task performance, balance, falls efficacy, and agitation. Results:The MDTT group showed a significant improvement in attention control, while the control group did not (P<0.001). A significant effect favored MDTT over control treatment for the secondary outcome of falls efficacy (P=0.02) and agitation (P<0.01). Conclusion:MDTT, a music therapy intervention that demands a high level of cognitive processing, enhances attention control, falls efficacy, and helps alleviate agitation in patients with mild-to-moderate dementia.

Project description:Patients with Parkinson's disease (PD) have difficulties while performing dual-task activities, a condition present in everyday life. It is possible that strategies such as transcranial Direct Current Stimulation (tDCS) can be associated with motor training enriched with dual-task training to improve the performance of two concurrent tasks. Currently, it is unclear whether specific tasks and clinical conditions of PD patients have different results after the intervention. Therefore, the proposed randomized controlled trial will examine task-dependency in enhancing the effects of tDCS-linked rehabilitation training on PD and the relationships between baseline outcomes in responders and non-responders to therapy. Fifty-six patients with Parkinson's disease will be recruited to participate in this controlled, double-blind randomized multicentric clinical trial. Patients in modified Hoehn & Yahr stage 1.5-3, age between 40 and 70 years will be included. Subjects will be randomly assigned to an experimental group (EG) and a control group (CG). The EG will perform treadmill gait training associated with dual task exercises+tDCS, while the CG will only engage in treadmill gait training+tDCS. Blinded testers will assess patients before and after 12 intervention sessions and after a 4-week follow-up period. All patients will undergo a screening and an initial visit before being assessed for primary and secondary outcomes. The primary outcome measure is functional mobility measured by Timed Up and Go Test. Secondary outcomes include cognitive function, participation, motor function and body function and structure. This study will evaluate the effectiveness of an intervention protocol with tDCS, dual-task training and gait training in patients with PD. The study will also highlight the clinical factors and variability between individuals that could interfere in the training of a specific task and influence the therapeutic effect.

Project description:ObjectiveTo estimate the effect of a moderate to high intensity aerobic and strength exercise training programme on cognitive impairment and other outcomes in people with mild to moderate dementia.DesignMulticentre, pragmatic, investigator masked, randomised controlled trial.SettingNational Health Service primary care, community and memory services, dementia research registers, and voluntary sector providers in 15 English regions.Participants494 people with dementia: 329 were assigned to an aerobic and strength exercise programme and 165 were assigned to usual care. Random allocation was 2:1 in favour of the exercise arm.InterventionsUsual care plus four months of supervised exercise and support for ongoing physical activity, or usual care only. Interventions were delivered in community gym facilities and NHS premises.Main outcome measuresThe primary outcome was score on the Alzheimer's disease assessment scale-cognitive subscale (ADAS-cog) at 12 months. Secondary outcomes included activities of daily living, neuropsychiatric symptoms, health related quality of life, and carer quality of life and burden. Physical fitness (including the six minute walk test) was measured in the exercise arm during the intervention.ResultsThe average age of participants was 77 (SD 7.9) years and 301/494 (61%) were men. By 12 months the mean ADAS-cog score had increased to 25.2 (SD 12.3) in the exercise arm and 23.8 (SD 10.4) in the usual care arm (adjusted between group difference -1.4, 95% confidence interval -2.6 to -0.2, P=0.03). This indicates greater cognitive impairment in the exercise group, although the average difference is small and clinical relevance uncertain. No differences were found in secondary outcomes or preplanned subgroup analyses by dementia type (Alzheimer's disease or other), severity of cognitive impairment, sex, and mobility. Compliance with exercise was good. Over 65% of participants (214/329) attended more than three quarters of scheduled sessions. Six minute walking distance improved over six weeks (mean change 18.1 m, 95% confidence interval 11.6 m to 24.6 m).ConclusionA moderate to high intensity aerobic and strength exercise training programme does not slow cognitive impairment in people with mild to moderate dementia. The exercise training programme improved physical fitness, but there were no noticeable improvements in other clinical outcomes.Trial registrationCurrent Controlled Trials ISRCTN10416500.

Project description:BACKGROUND:Results from a phase 2a study indicated that treatment with the novel ?7 nicotinic acetylcholine receptor agonist ABT-126 25 mg once daily (QD) was associated with a trend for improvement in cognition in subjects with mild-to-moderate Alzheimer's dementia (AD). A phase 2b program was designed to evaluate a broader dose range of ABT-126 as monotherapy in subjects with mild-to-moderate AD. The program consisted of a double-blind, placebo and active controlled study of ABT-126 (dose range 25-75 mg) and an open-label extension study (75 mg). METHODS:The randomized double-blind study enrolled 438 subjects (Mini-Mental Status Examination score of 10-24, inclusive) not currently taking acetylcholinesterase inhibitors or memantine. Subjects received 24 weeks of ABT-126 25 mg QD (n?=?77), ABT-126 50 mg QD (n?=?108), ABT-126 75 mg QD (n?=?73), donepezil 10 mg QD (n?=?76), or placebo (n?=?104). The primary endpoint was the change from baseline to week 24 in the 11-item Alzheimer's Disease Assessment Scale-Cognitive subscale (ADAS-Cog) total score. Subjects completing the double-blind study could enroll in the 28-week open-label extension study. Adverse events (AEs) and other safety parameters were monitored in both studies. RESULTS:A total of 367 patients (83.8 %) completed the double-blind study and 349 (79.7 %) entered the open-label study. Compared with placebo, donepezil significantly improved ADAS-Cog 11-item total scores from baseline to week 24 (-2.29?±?0.95; one-sided P?=?0.008). No ABT-126 dose demonstrated a statistically significant improvement vs placebo at week 24 in the ADAS-Cog total score: ABT-126 25 mg, -0.47?±?0.94 (P?=?0.309); ABT-126 50 mg, -0.87?±?0.85 (P?=?0.153); and ABT-126 75 mg, -1.08?±?0.94 (P?=?0.127). Rates of serious AEs and discontinuations due to AEs were similar across treatment groups. The most frequently reported AEs in both studies were constipation, fall, and headache. No clinically meaningful changes were observed in other parameters. CONCLUSIONS:In the double-blind trial, donepezil significantly improved ADAS-Cog scores but no statistically significant improvement was seen with any ABT-126 dose. ABT-126 had an acceptable safety profile in subjects with mild-to-moderate AD in both studies. TRIAL REGISTRATION:ClinicalTrials.gov NCT01527916 , Registered 3 February 2012 (randomized trial).

Project description:BackgroundFunctional independence and safe mobility, especially in older people, mostly rely on the ability to perform dual tasks, particularly during activities with variable- and fixed-priority attention. The aim of this study is to compare the dual-task training with progression from variable- to fixed-priority instructions versus dual-task training with variable-priority on gait speed in community-dwelling older adults.MethodsThis is an assessor- and participant-blinded, two-arm, randomized controlled trial with 60 community-dwelling male and female older adults between the ages of 60 and 80 years old. Participants will be randomly allocated into either the intervention group or the control group using a computer-generated permuted block randomization schedule. The intervention group will undertake a progressive dual-task training in which the participants will be progressively submitted to dual-task walking and postural balance exercises with variable- to fixed-priority instructions. The control group will be submitted to dual-task training with variable-priority attention exercises. Both groups will receive 48 sessions lasting for 60 min each over 24 weeks. The primary outcome will be the gait speed under single- and dual-task conditions. Secondary outcomes will include spatiotemporal gait parameters, functional balance, executive function, falls, quality of life, and depression symptoms. All the analyses will be based on the intention-to-treat principle.DiscussionThis is the first assessor- and participant-blinded, two-arm, randomized controlled trial with 6 months of intervention and an additional 6-month post-training follow up aiming to evaluate the effectiveness of training with progression from variable- to fixed-priority instructions on gait biomechanics, postural balance, falls episodes, executive functioning, and quality of life in community-dwelling older adults. If our hypotheses are confirmed, this training protocol can be implemented widely to improve gait speed and other functional activities and quality of life in community-dwelling older adults. This study protocol can be used to improve these functional aspects of community-dwelling older adults. This study may also contribute to future guidelines for the improvement of these clinical and biomechanical aspects in older people.Trial registrationClinicalTrials.gov Identifier - NCT03886805, Registered 22 March 2019.
