A diet containing compounds found in green tea and carrots reversed Alzheimer\u2019s-like symptoms in mice genetically programmed to develop the disease, USC researchers say.
\nResearchers emphasize that\u00a0the study<\/a>, published in the Journal of Biological Chemistry, was in mice, and many mouse discoveries never translate into human treatments. Nevertheless, the findings lend credence to the idea that certain readily available, plant-based supplements might offer protection against dementia in humans.
\n\u201cYou don\u2019t have to wait 10 to 12 years for a designer drug to make it to market; you can make these dietary changes today,\u201d said senior author\u00a0Terrence Town<\/a>, a professor of physiology and neuroscience at the Keck School of Medicine of USC\u2019s\u00a0Zilkha Neurogenetic Institute<\/a>. \u201cI find that very encouraging.\u201d
\nDiet and Alzheimer\u2019s: Combination therapy<\/strong>
\nWhat\u2019s more, the study supports the idea that combination therapy, rather than a single magic bullet, may offer the best approach to treating the 5.7 million Americans living with Alzheimer\u2019s. Combination treatment is already the standard of care for diseases such as cancer, HIV infection and rheumatoid arthritis.
\nFor this study, the researchers took a look at two compounds, EGCG, or epigallocatechin-3-gallate, a key ingredient in green tea, and FA, or ferulic acid, which is found in carrots, tomatoes, rice, wheat and oats.
\nThe researchers randomly assigned 32 mice with Alzheimer\u2019s-like symptoms to one of four groups with an equal number of males and females. For comparison, each group also included an equal number of healthy mice. For three months, the mice consumed a combination of EGCG and FA, or EGCG or FA only, or a placebo. The dosage was 30 milligrams per kilogram of body weight \u2014 a dosage well-tolerated by humans and easily consumed as part of a healthy diet.
\nDiet and Alzheimer\u2019s: Testing results<\/strong>
\nBefore and after the three-month special diet, scientists ran the mice through a battery of neuropsychological tests that are roughly analogous to the thinking and memory tests that assess dementia in humans. Of particular note was a maze in the shape of a Y, which tests a mouse\u2019s spatial working memory \u2014 a skill that humans use to find their way out of a building.
\nHealthy mice instinctively explore each arm of the Y maze, looking for food or a route to escape and entering the three arms in sequence more often than by chance alone. Impaired mice can\u2019t do this as well as their mentally healthy counterparts.
\n\u201cAfter three months, combination treatment completely restored spatial working memory and the Alzheimer\u2019s mice performed just as well as the healthy comparison mice,\u201d Town said.
\nHow did it work? Town says one mechanism appeared to be the substances\u2019 ability to prevent amyloid precursor proteins from breaking up into the smaller proteins called amyloid beta that gum up Alzheimer patients\u2019 brains. In addition, the compounds appeared to reduce neuroinflammation and oxidative stress in the brain\u2014key aspects of Alzheimer\u2019s pathology in humans.
\nTown said he and his lab will continue exploring combination treatment, with a focus on plant-derived substances that inhibit production of the sticky amyloid beta plaques.
