Scientists have made enormous strides in understanding how Alzheimer’s disease affects the brain. Many of these insights point toward new therapies and improved ways to diagnose the disease and monitor its progression.
At any given time, dozens of studies are recruiting participants to help explore these exciting new approaches. Every clinical study contributes valuable knowledge, regardless of whether the experimental strategy works as hoped.
Without study participants, however, progress is stalled, and scientists report growing difficulty finding enough volunteers to complete these studies.
If you or a friend or family member has Alzheimer’s or another dementia — or even if you don’t — you can help advance knowledge about this illness. By participating in a clinical study, you can help new treatments, preventive strategies and diagnostic tools to become a reality.
What is a clinical study?
A clinical study is any medical research project involving human volunteers. Research into improved approaches usually begins with laboratory work or animal studies. Following early success with these methods, new strategies must demonstrate their effectiveness in the final proving ground of human testing.
What is a clinical trial?
A clinical trial is a specific type of study in which one group of volunteers gets an experimental treatment, while a similar group gets a placebo ( a look-alike “sugar pill”). Scientists evaluate the effect of the new treatment by comparing outcomes in the two groups.
Phases of clinical trials
The U.S. Food and Drug Administration (FDA), which regulates medical products and drugs, oversees a rigorous process for testing experimental treatments that is based on sequential phases. The treatments must perform well enough in each phase to progress to the next one. If a treatment performs adequately in all stages through Phase III, the FDA reviews the data and determines whether to approve the drug for use in general medical practice.
- Phase 1 trials, the first stage of human testing, typically enroll fewer than 100 volunteers. These studies are primarily concerned with assessing the safety of a drug and whether it has risks or side effects.
- Phase II trials enroll up to a few hundred volunteers with the condition the drug is designed to treat. These studies provide further information about the safety of the drug and focus on determining the best dosage. Scientists also watch for signs of effectiveness, but Phase II trials are generally too small to provide clear evidence about benefit.
- Phase III trials may enroll several hundred to thousands of volunteers, often at multiple study sites nationwide or internationally. Phase III trials provide the chief evidence for safety and effectiveness that the FDA will consider when deciding whether to approve a new drug.
- Phase IV trials, also called post-marketing studies, are often required by the FDA after a drug is approved. The trial sponsor must monitor the health of individuals taking the drug to gain further insight into its long-term safety effectiveness and the best way to use it.
How to find a study near you
Alzheimer’s Association TrialMatch is a clinical studies matching service. TrialMatch uses information about your diagnosis, location and preferences to match a person with current clinical studies. Finding the right trial can be done over the phone or online. Once a match is found, and with your permission, a TrialMatch specialist will contact you to answer questions.
If you would like to consider participating in a clinical study, call 1-800-272-3900 or visit alz.org/trialmatch. More information about clinical studies can also be found at clinicaltrials.gov.
Do your snacking habits affect brain health? Could your diet choices help to reduce (or elevate) your risk for diseases like Alzheimer’s? As the prevalence of Alzheimer’s disease continues to rise (more than 5 millions Americans have a diagnosis), many have been intrigued by these questions. Unfortunately, there is no proven method for preventing Alzheimer’s disease and the research into its prevention is lacking. However, an emerging body of scientific research indicates that certain food choices may be conducive to a healthy brain.
Ever heard the axiom “healthy mind, healthy body”? It’s often true! Hypertension, diabetes, high cholesterol, and other chronic diseases have been associated with an increased risk for developing Alzheimer’s disease and other types of dementia. These diseases are harmful to the blood vessels in the body, and they can ultimately cause a lack of blood flow to the brain.
Want to ensure that your diet will protect your body and your mind? Adhering to a heart healthy food selection, like the Mediterranean diet, may help.
The benefits of diet on heart health are already well-documented, and many researchers believe that these same disease fighting foods can be beneficial in protecting the brain. The studies conducted on this subject have yielded promising results, however, more research must continue in order to learn more about effective prevention strategies for Alzheimer’s.
Don’t forget, aging doesn’t start when we reach 65. It’s happening to us all the time, everyday! Commit to a healthy lifestyle long-term, and you will be more likely to stave off chronic diseases, like Alzheimer’s. Life is a marathon, not a sprint!
Want to give it a spin? Below is a sample grocery list that reflects adherence to the Mediterranean diet. The most effective eating plan is one that works with your preferences and lifestyle. Experiment with foods that are most appealing to you and enjoy!
