for how long?<\/strong>\u00a0 For 12 weeks the trial group drank from 2 to 2 1\/2 cups of wild blueberry juice&#8211;the amount was based on their body weight.\u00a0 During the test period everyone had to avoid any additional berries, cherries, grapes, pomegranates, grape juice, or wine to make sure that only blueberry juice was affecting the results.<\/p>\n<p><strong>How were their memories tested?<\/strong>\u00a0 All the participants took\u00a0 pre and post tests that measured their memory function&#8211;the Verbal Paired Associate Learning Test (V-PAL) and the California Verbal Learning Test (CVLT).\u00a0 Both tests are good measures of progressive neurodegeneration and are sensitive to both age-related memory changes, as well as early and more advanced Alzheimer&#8217;s disease.<\/p>\n<p><strong>So, how did the blueberry juice folks do compared to the fake blueberry juice folks?<\/strong>\u00a0 Turns out that the blueberry juice definitely improved their memories.\u00a0 There was significant improvement in the post test of the blueberry juice drinkers, and at the end of the 12-weeks, the blueberry juice group tested significantly better against the placebo group.\u00a0 After 12 weeks the blueberry group&#8217;s\u00a0 V-PAL cumulative learning test scores went from 9.3 points to 13.2 points.\u00a0 The scores on their CVLT word list recall improved from 7.2 points to 9.6 points.\u00a0 <\/p>\n<p><strong>Memory wasn&#8217;t the only thing that improved with the blueberry juice.<\/strong>\u00a0 The researchers also did pre and post tests on depression and fasting glucose levels.\u00a0 After 12 weeks the blueberry juice drinkers had notable reductions in their depression symptom scores, and their fasting glucose levels were reduced.\u00a0 <\/p>\n<p>Both of these changes further support the neurocognitive benefit of blueberry juice.\u00a0 It turns out that the anthocyanins (the polyphenols in blueberries) are not only anti-inflammatory, but they help to &#8220;get rid of&#8221; excess glucose, which is known to damage the brain&#8211;and just might be one of the reasons that blueberries help to improve memory.<\/p>\n<p><strong>How do blueberries benefit the brain?<\/strong>\u00a0 They contain polyphenolic compounds, most prominently anthocyanins, that have antioxidant and anti-inflammatory properties.\u00a0 Anthocyanins are known to increase the signaling between neurons in the brain, improve memory function and slow down neurodegeneration.<\/p>\n<p><strong>What happens next?<\/strong>\u00a0 This was just a first step.\u00a0 It&#8217;s a small study, but the results were encouraging and suggest that consistent supplementation with blueberries may offer an approach to prevent or slow down neurodegeneration.\u00a0\u00a0\u00a0 As every researcher says at the end of their articles&#8211;&#8220;Replication of the findings in a larger, controlled trial will be important to corroborate and amplify these data.&#8221;\u00a0 Stay tuned.<\/p>\n<p style=\"text-align: left;\"><strong>What am I going to do?<\/strong>\u00a0 When I was at<strong> Trader Joe&#8217;s<\/strong> on Sunday, instead of picking up my usual pomegranate juice for my green smoothies, I decided to try a bottle of their <strong>Just Blueberry Unfiltered 100% Juice<\/strong>.\u00a0 It&#8217;s not made from wild blueberries, but what the heck.\u00a0 I think I may also start throwing in some of the <strong>Wyler&#8217;s Frozen Wild Blueberries<\/strong> into my smoothies as well&#8211;alternating with <strong>TJ&#8217;s Frozen Black Raspberries.\u00a0<\/strong> A memory is a terrible thing to lose!<\/p>\n<p style=\"text-align: center;\"><strong><span style=\"color: #bf5f00;

The book is about neuroplasticity&#8211;\u00a0 how our brains are not static, but can change and improve, even as we age.\u00a0 Much of this research is credited to Dr. Michael Merzenich who has pioneered computer-learning activities for children, and has recently developed memory-training programs for adults.\u00a0 <a href=\"http:\/\/www.positscience.com\/\">Click here <\/a>to learn more.<\/p>\n<p>Writing this blog has given me a chance to take time out to study, learn, and concentrate on new areas of research&#8211;and to understand it well enough to be able to write about it.\u00a0 Without undergoing any &#8220;brain testing&#8221;

we&#8217;re more likely to have a solid sense of who we are and be skilled at a career.\u00a0 <em><strong>We still regard ourselves as active, but we have a tendency to deceive ourselves into thinking that we are learning as we were before.<\/strong><\/em><\/p>\n<p><em><strong>We rarely engage in tasks in which we must focus our attention as closely as we did when we were younger, trying to learn a new vocabulary or master new skills.<\/strong><\/em><\/p>\n<p><em><strong>Such activities as reading the newspaper, practicing a profession of many years, and speaking our own language are mostly the replay of mastered skills, not learning.<\/strong><\/em><\/p>\n<p><em><strong>By the time we hit our seventies, we many not have systematically engaged the systems in the brain that regulate plasticity for fifty years.<\/strong><\/em><\/p>\n<p>That&#8217;s why learning a new language in old age is so good for improving and maintaining the memory generally.\u00a0 Because it requires intense focus, studying a new language turns on the control system for plasticity and keeps it in good shape laying down sharp memories of all kinds.\u00a0 And it keeps up the production of acetylcholine and dopamine.<\/p>\n<p><em><strong>Anything that requires highly focused attention will help that system&#8211;learning new physical activities that require concentration, solving challenging puzzles, or making a career change that requires that you master new skills and material.&#8221;<\/strong><\/em><\/p>\n<p><\/span><\/p><\/blockquote>\n<p><span style=\"color: #8b8b8b;\"><\/p>\n<p><strong><span style=\"color: #bf5f00;\"><span style=\"font-size: 14px;\">So, yes, maybe go ahead and add blueberry juice to your daily diet, but better yet, find something that&#8217;s really interesting to you and start learning all about it&#8211;even though there won&#8217;t be a test on it in 2 weeks!<\/span><\/span><\/strong><\/p>\n<p><\/span><br \/><span style=\"color: #8b8b8b;\"><\/span><br \/><span style=\"color: #8b8b8b;\"><\/p>\n<p style=\"color: #000000;\">\n<p><\/span><br \/><span style=\"color: #8b8b8b;\"><\/span><\/p>\n<blockquote><p><span style=\"color: #8b8b8b;\"><\/span><br \/><span style=\"color: #8b8b8b;\"><\/span><br \/><span style=\"color: #8b8b8b;\"><\/span><br \/><span style=\"color: #8b8b8b;\"><\/span><br \/><span style=\"color: #8b8b8b;\"><span style=\"color: #000000;
