Comparison of Early Interventions in the Prevention of Alzheimer’s Disease in Patients with Down Syndrome: A Systematic Review
Background: Down Syndrome (DS) is the most common chromosomal abnormality with an incidence of 1:700 live births. Alzheimer’s disease (AD) affects almost all of these individuals from the age of 30, whose susceptibility is on the rise with increasing life expectancy. However, interventions can limit or improve cognitive decline. Objectives: To compare early interventions in the prevention of AD in patients with DS. Methods: Randomized Controlled Trial published in English, in the last 5 years, in humans, at PUBMED. Were included studies involving participants over 18 years old, diagnosed with DS and those with unclear interventions were excluded. Six articles were found and after applying the criteria, two studies were part of this review. The PRISMA scale was used. Results: Ptomey et al. (2018) intervened with online exercise, selecting 27 participants divided into two groups: A) one session/week; B) two sessions/ week. After 12 weeks it was observed that group B showed improvement in learning compared to group A. Sano et al. (2016) performed an intervention with Vitamin E (VE) for three years in 337 individuals, segregated in: A) 1,000 IU, orally, twice/day; B) placebo. There was no significant difference in the progression of cognitive, functional, behavioral and clinical deterioration between the groups. Conclusions: The practice of physical exercise proved to be promising in the prevention of AD, however the use of VE did not show significant results. Further studies on the subject are needed.
