What is the purpose of this trial?

This trial explores whether certain activities can help individuals with Early-Onset Alzheimer's Disease. Participants will engage in either cognitive training (also known as computerized cognitive training or cognitive therapy) and Tai Chi-Qi Gong exercises, or play brain games and perform stretching (also referred to as flexibility exercises or physical therapy) for 14 weeks. The researchers aim to determine if these activities improve thinking skills, daily functioning, and mood more effectively than the alternatives. Suitable candidates have already been diagnosed with Early-Onset Alzheimer's, are fluent in English, and have a friend or family member who knows them well. As an unphased trial, this study offers a unique opportunity to contribute to understanding how lifestyle activities can impact Alzheimer's, potentially benefiting future patients.

Do I need to stop my current medications for this trial?

The trial protocol does not specify whether you need to stop taking your current medications.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Studies have shown promising results for both computerized brain training and Tai Chi-Qi Gong exercises. Research suggests that structured computerized brain training can enhance thinking skills and daily activities in people with early Alzheimer's disease. Participants generally find these activities manageable, with no major safety concerns reported in previous studies.

Similarly, Tai Chi-Qi Gong has demonstrated potential benefits for both mental and physical health in older adults. Evidence indicates that these exercises can improve thinking skills and might even slow memory loss. Like brain training, Tai Chi-Qi Gong is usually safe, with studies highlighting its positive effects rather than any negative ones.

Overall, existing research considers both treatments safe and well-tolerated. Participants in studies using these methods have generally not reported serious side effects. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about these treatments for early onset Alzheimer's because they offer a holistic and non-pharmacological approach. Unlike typical treatments that rely on medications to manage symptoms, these treatments focus on physical and mental exercises. Tai Chi- Qi Gong and Cognitive Training aim to improve cognitive function and overall well-being through movement and brain exercises, which could provide a natural way to slow disease progression. This approach might offer a safer alternative with fewer side effects compared to traditional drug therapies.

What evidence suggests that this trial's treatments could be effective for Early-Onset Alzheimer's Disease?

Research shows that computer programs for brain training can improve memory and thinking skills. One study found significant boosts in various types of memory, such as remembering words, images, and temporarily needed information. Another study found that this training can delay the onset of mild cognitive impairment (MCI) and dementia, early stages of Alzheimer's disease. In this trial, participants in the Experimental Cognitive Training and Tai Chi-Qi Gong Arm will receive Cognitive Training.

Research also suggests that Tai Chi and Qi Gong benefit both body and mind. One analysis found these exercises improved physical and mental abilities in older adults. Another study showed that Tai Chi can slow mental decline in elderly individuals with emerging memory problems. Participants in the same arm will also receive Tai Chi-Qi Gong exercise training.

Meanwhile, the Active Control Arm will receive Brain Games and stretching exercises. Overall, combining brain training with Tai Chi and Qi Gong appears promising for improving mental health in individuals with early-onset Alzheimer's. ^{1 6 7 8 9}

A 1-year qigong exercise program significantly reduced the risk of cognitive decline in older Chinese adults compared to a stretching exercise, with a notable odds ratio of 0.314 indicating lower progression of cognitive impairment.

Participants in the qigong group showed significantly higher scores in global cognition and various cognitive domains (memory, visuospatial ability, and language) compared to the stretching group, highlighting the effectiveness of qigong in improving cognitive functions.

Lifestyle interventions, such as education, social engagement, and exercise, can significantly reduce the risk of developing Alzheimer's disease (AD), as shown in a systematic review of various studies.

The review highlights that combining multiple lifestyle changes can be effective in delaying or preventing AD, addressing the need for alternative approaches given the limited treatment options available.

In a 1-year study involving 389 Chinese elders at risk of cognitive decline, those practicing Tai Chi showed a significantly lower risk of developing dementia compared to those doing stretching and toning exercises, with an odds ratio of 0.21.

Participants in the Tai Chi group also demonstrated better preservation of cognitive function and mood, with notable improvements in memory recall and reduced depressive symptoms, indicating the potential benefits of mind-body exercises for cognitive health.

The prevalence of Tai Chi and Qigong (TCQ) use among U.S. adults increased significantly from 1.17% in 2007 to 1.70% in 2017, indicating a growing interest in these mind-body practices over the decade.

The increase in TCQ use was particularly notable among older adults, low-income individuals, and those who were physically inactive, suggesting that TCQ may be a beneficial and accessible form of exercise for these populations to address health disparities.

A study involving 48 individuals with amnestic mild cognitive impairment found that both a combined intervention of Taoist Tai Chi (TTC) and a memory intervention program (MIP) and MIP alone improved memory strategy knowledge and everyday memory behaviors.

However, the addition of TTC did not provide any additional benefits for cognition, gait, or balance, suggesting that while both interventions were effective, TTC did not enhance the outcomes beyond those achieved with MIP alone.

A 12-week Tai Chi program for older adults with mild cognitive impairment (MCI) or dementia was found to be feasible and well-accepted, with an impressive attendance rate of 87% and no reported adverse events.

Participants with MCI showed significant improvements in grip strength and health-related quality of life, while both MCI and dementia groups improved their mobility as measured by the Timed Up and Go (TUG) test, indicating that Tai Chi can enhance physical functioning in this population.

Tai Chi, a mind-body exercise, has been shown to improve cognitive functions and reduce symptoms of mild cognitive impairment (MCI) in older adults, suggesting it could be an effective management strategy for this condition.

The potential benefits of Tai Chi may arise from its ability to activate brain signals, enhance connectivity, increase brain volume, and modulate factors related to brain health, indicating a multifaceted mechanism of action.
