ABSTRACT

This randomized controlled trial aims to investigate the effect of 12 weeks of therapeutic exercise on cognitive function and daily activities in patients with mild Alzheimer's disease (AD). A total of 171 patients with mild AD from the Amarousion Day Care Center of the Alzheimer Society of Athens and the Athens General Hospital "G. Gennimatas" were randomly divided into three groups. Group A (aerobic and resistance exercise, n = 57), group B (resistance exercise, n = 57), and group C (control group, n = 57). Group A followed a weekly program consisting of 5 days with 30 min walking and 3 days with resistance exercises for about 45 min. Group B followed only a resistance exercise program, the same as group A. Group C did not participate in any exercise program. After the intervention, cognitive function was assessed with the Cognitive Examination-Revised (ACE-R), Trail Making Test A-B (TMT A-B), and Digit Span Test Forward and Backward (DST F-B) and daily activities with the instrumental activities of daily living scale (IADLs). A significant intervention effect was observed for all outcome measures (global cognitive function and instrumental activities of daily living). ANCOVA Bonferroni corrected post hoc tests revealed that the aerobic and resistance group improved compared to the control group on all measurement scales. The resistance group also showed an improvement compared to the control group. No significant effects were found between the aerobic and resistance group and the resistance group in any of the outcome measures.

ABSTRACT

Dementia involves the loss of cognitive abilities and represents a decline from the prior level of function which impairs functional abilities in day-to-day life. No previous experimental research has been done to assess mental imagery (MI) effectiveness in the motor, cognitive and emotional status of individuals with early-stage dementia. One hundred and forty older individuals with early-stage dementia from the Day Care Centre of the Alzheimer Association in Athens will take part in this study. The sample will be randomly divided into three groups: MI and physical exercise (intervention group), only physical exercise (1st control group), and neither MI nor physical exercise (2nd control group). Assessment will be obtained one week prior to the program, in the middle of the program (6th week of the intervention program) and after the end of the program (13th week of the intervention program). Participants of the intervention group will perform a 30-minute MI programme after the end of every physiotherapy session. Reliable and valid instruments will be used to assess the primary outcomes, i.e., balance and functional status as well as the secondary outcomes i.e., cognitive ability, emotional state and quality of life. The two-way Mixed ANOVA with factors 'intervention' (between groups) and 'time' (within group) will be used as a statistical analysis. Approvals of clinical trial protocol: a) UNIWA Research Committee study protocol approval: 93292 - 26/10/2021. b) ClinicalTrials.gov: ID NCT05232526.
