Alzheimer’s disease is not normal forgetfulness as we age. Instead, it is a specific form of mental decline. And according to the Alzheimer’s Association it accounts for nearly 80 percent all dementia cases. Natasa Dragicevic, MD, PhD., behavioral neurologist and Alzheimer’s disease specialist with Renown Institute for Neurosciences, weighs in on diagnosing it and the importance of early medical action. How to Diagnose Alzheimer’s Disease In general, the signs of Alzheimer’s disease occur slowly, getting worse over time. For example, forgetfulness is a daily search – for shoes, keys and other misplaced items. Not only is memory affected, but also speech patterns and behavior. There is no single test for Alzheimer’s disease. “Specifically, a neurologist should be the one to diagnose Alzheimer’s disease given differences in presentation,” clarifies Dr. Dragicevic. “And ideally a behavioral neurologist (Alzheimer’s sub-specialist) will be managing the treatment,” she adds. Brain Imaging Diagnosing Alzheimer’s disease involves multiple approaches and medical providers. In short, medical history is reviewed along with a physical exam, lab tests and other diagnostic testing. “A medical workup includes a variety of tests. These include MRI and other brain imaging, as well as neurological and psychological testing. Furthermore, a lumbar puncture is performed to look for markers of the disease,” she states. What Causes Alzheimer’s disease? Although no one knows the cause, researchers think many factors play a role. Uncontrollable risk factors include your genetics and having a family member with the disease. However, the controllable risk factors include: reducing the risk of head injury and keeping your heart healthy. It’s important to realize that high blood pressure, high cholesterol, stroke and diabetes play a role in brain health. Blood loss to the brain causes vascular dementia, leading to long-term blood vessel damage. Symptoms of Alzheimer’s disease Generally speaking, the signs of this disease differ in each person. Yet noticeable behaviors include: • Losing the way to familiar places • Forgetting to pay bills • Trouble finding the right words when talking • Repeating questions • General confusion • Social withdrawal Alzheimer’s Disease – Benefits of Early Diagnosis Equally important, spotting Alzheimer’s disease early allows more time to benefit from medications and possible clinical trials. Likewise, nutrition and exercise changes can be made, increasing blood flow to the body, and perhaps delaying symptoms. Early diagnosis also allows for personal health decisions and quality-of-life conversations to take place.   According to the Alzheimer’s Association, these benefits include: 1. Medical advantage 2. Emotional and social comfort 3. Time to plan ahead 4. Cost savings A Brain Supporting Lifestyle “At the present time, treatment is limited,” explains Dr. Dragicevic. “Usually Alzheimer’s is a progressive ongoing disease – any management at this time is purely symptomatic.” However, she states the following lifestyle changes can help support brain health: • New hobbies such as painting, pottery, music classes or learning a new language • Crosswords, puzzles and playing games, such as Scrabble • Brain challenging mobile apps, such as Luminosity • 30-45 minutes of mild to moderate physical activity per day, such as walking • Eating a Mediterranean diet (primarily plant based foods)

There are many misconceptions about clinical research, so we have unpacked a few common myths we hear to help you make an informed decision in your healthcare. Misconception #1: If I join a clinical trial, I’ll just be a guinea pig. Quite the opposite is true! Through honest and respectful conversation, we ensure all participants are informed of the benefits and risks associated with the clinical trial during the informed consent process. Being in a clinical trial is voluntary, and we respect our patients’ decision to join or decline to participate in the clinical trial. You can always change your mind at any time as well. When patients join a clinical trial, they receive an additional team of healthcare professionals, including additional physicians, pharmacists and research coordinators, dedicated to their safety and well-being. This means that clinical trial participants often receive more support than they would in the standard treatment setting. Misconception #2: Clinical trials are too dangerous because they use new treatments that haven’t been tested. We recognize that there are different levels of risk associated with participating in a clinical trial depending on the type of study. However, new treatments are only reviewed through clinical trials after they have gone through extensive testing. New treatments that do not show promising results for safety and potential benefit during laboratory testing do not receive approval to begin clinical trials. Your research team reviews any expected benefits and risks identified from previous studies during the informed consent process, as well as any updates that occur throughout the duration of the clinical trial. The research team stays in close contact with you during the entire process, documenting and treating any side effects that you experience for both your safety and the safety of participants like you. Misconception #3: I don't want to join a trial because I could be wasting my time receiving a placebo. A placebo is a substance that has no therapeutic effect, sometimes called a “sugar pill.” Participants who receive a placebo during a clinical trial are very important, helping researchers definitively determine the specific good and bad effects of the new medication. Many clinical trials that involve a placebo also offer what is called an open label extension or cross-over study. Cross-over studies ensure that anyone taking the placebo can begin receiving the new medication, often for several years. Cross-over studies help clinician researchers understand the long-term effects of a medication while also giving patients free access to novel care for several months and even years.
