It’s true there is no cure for dementia, yet studies suggest your life choices today can reduce brain decline in the future. How important is diet to brain health? Food is the foundation of your body. Fats, carbs and protein provide the energy for your cells and metabolism. So the quality and amount of food you eat directly affects your brain. Specifically, researchers are paying special attention to the link a high sugar diet and/ or an unhealthy fat diet may have on your brain. Your brain on sugar According to the Alzheimer’s Association, when too much sugar is in the bloodstream for long periods of time, it can damage the brain cells. Many people with diabetes may develop brain abnormalities, and these changes may increase chances of dementia — research is still being done to understand this connection. Many U.S. adults have prediabetes with blood sugar higher than normal. Insulin resistance often leads to diabetes. Insulin resistance has been linked to metabolic syndrome, which is a precursor for cardiovascular and cerebrovascular disease (heart attack, stroke). Some signs of metabolic syndrome include: Large waist size (40 inches or more for men, 35 inches and up for women) Low HDL (good) cholesterol level Higher than normal blood pressure — 130/85 and above Current research suggests too much sugar in the blood causes inflammation, which can damage brain cells. High carbohydrate foods, such as sweetened beverages, chips, white rice, white potatoes, bagels, cereals and desserts, have been shown to raise blood sugar. Although anyone can get diabetes, Hispanic Americans and African Americans are at greater risk.

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)
